**Totomaru Isshiki** (一色都々丸いしきととまる, *Isshiki Totomaru*), frequently shortened to **Toto** (トト, *Toto*), is a police detective of the Metropolitan Police Department. He is currently helping Ron Kamonohashi investigate cases by pretending to be the one who solves them.

## Physical description

Totomaru is a slender, young man with short brown hair and either gray or brown eyes.

While Toto may not be particularly athletic, he is full of energy.

To work, he usually wears a gray suit with an assortment of ties; the one he wears the most is striped in shades of blue. He sometimes wears a beige coat over his work clothes, and seldom a black jacket.

Like Ron, who often wears clothes featuring Japanese sweets, Toto sometimes dons clothes depicting food or bearing the name of dishes, though the food on Toto's attire (e.g. sushi and *osuimono*) is more savory rather than sweet.

## Personality and traits

Toto is pure-hearted, empathetic, and straightforward. He does not hesitate to help others in need, paying no heed to what problems it may cause; he just wants to do what he thinks is right. For that reason, his body often acts before his mind.

Though many (initially) believe he is unsuited for detective work and he is mostly delegated to paperwork, Toto is very dedicated to his occupation, wanting nothing more than to ensure the safety of the citizens. He greatly values life and often prays for the victims of his cases. Totomaru works hard and much, pulling all-nighters if he has too. This makes him, ultimately, an integral part of his division.

Furthermore, Totomaru says what he thinks without hesitation and voices his thoughts out loud without realizing it. According to Ron Kamonohashi, this is an indicator that he was a spoiled child and brought up in a refined environment. Toto also moves his mouth when he talks to himself.

When something amazes him, Toto usually exclaims "Wowza!" (すごっ, *Sugo*, lit. "amazing").

## Biography

### Early life

Because his parents were always busy, Totomaru was raised by his grandmother.

He eventually became a detective at the Metropolitan Police Department. In his early career, Toto got tricked and let a culprit escape three times and was once reported for questioning people in a residential area at 3 a.m.

### Metropolitan Serial Drownings Case

Totomaru's division is working intensely to find the culprit behind the Metropolitan Serial Drownings Case. He wants to help as well, but when a fifth victim is discovered, Amamiya tells Toto to go home and sleep because he would only be a "nuisance" due to his incompetence. Saddened, Toto seeks out Kiku to lament over the situation, and Kiku refers him to a private detective whom he believes to be the only one capable of solving this case.

Totomaru heads to the Maison du Kamonohashi where Ron Kamonohashi lives. Though he is initially unwilling to hear him out, Ron invites Toto inside when he tells him that Kiku sent him. Toto asks for his help to solve the current string of serial murders, and Ron declines, as he does not do any detective work anymore. However, when Amamiya calls Toto, and Ron overhears that another victim was discovered, he gets the insuppressible urge to solve the case, even though he knows he should not because of his incurable "fatal flaw." Toto assures him that he will ensure nothing bad happens, and they head to Kazahana Park.

There, Ron examines Okamasa's corpse and deduces that he is a businessman and that he was drowned and robbed. Toto then hands him a map that marks all the places where the victims were found; to Toto's amazement, Ron can solve the case after briefly studying the map. Afterward, Ron takes Totomaru shopping, and although he is quite confused, Totomaru allows Ron to dress him in horrid designer clothes and send him to a barber for a haircut. Before Toto goes inside, Ron urges him not to fall asleep and pretend to be a wealthy businessman.

Toto does as he was told, and just when the barber is about to drown him in the basin, Ron—who was waiting outside—picks the lock and reveals him as the serial killer. The barber filled the sink with oxygen-deficient air, making it easy for him to drown his victims. Upon being confronted, the barber runs away, and Toto and Ron chase him to the roof. The barber confesses and says he did it for revenge and money. To Toto's horror, Ron then pressures the barber into jumping off the roof, and the barber complies. Without much thought, Toto moves forward and manages to grab the barber at the last minute which impresses Ron. He then saves both Toto and the barber from falling.

Later, they return to Ron's apartment where Ron enlightens Totomaru about Kill on Sight, his strange ability that allows him to persuade murderers into committing suicide. Because he cannot control this power, he needs Toto's help: Ron will solve Toto's cases, and Toto will support Ron and pretend to be the one solving them.

### Locked Room Piggy Bank Theft Case

Sometime later, Toto visits Ron again. Ron immediately asks him if he has a case for him, and when Toto negates, he throws himself to the ground in frustration. Ron explains that he used to be BLUE's top student before he was expelled after being accused of murder. Because he lost his detective license as well and cannot solve cases without it, he needs Totomaru's assistance. Toto informs him that he is his division's "dead weight" and only receives small, unremarkable cases; today, while his colleagues are looking into a corpse found by a river, he has to handle the Locked Room Piggy Bank Theft Case. Ron, however, is happy to take on any case, no matter how big or small. They then head to the crime scene.

There, they are greeted by the younger sister who shows them her piggy bank and explains that she was away two days ago. When she returned, the piggy bank had become lighter; before, it used to be as heavy as a statue. She and her older sister have also been receiving weird silent phone calls lately. The older sister then arrives and testifies that she returned home earlier than the younger sister. Because the older sister insists that the piggy bank weighs the same as before, they decide to break it open, revealing significantly fewer coins than before. Ron orders Totomaru to send the coins to forensics and says that they will meet up later because he needs to take a walk. Although Totomaru is thoroughly confused, he complies.

At the river, Toto receives a call from forensics: Only the older sister's fingerprints were found on the coins. He and Ron then join Amamiya by the riverbank where she and her subordinates are investigating. After Ron examines the corpse, he makes Toto present his deduction: The piggy bank theft and the river corpse cases are connected. The dead man is the older sister's stalker who she killed in self-defense with the piggy bank. She replaced the broken piggy bank and transported the body to the river in a suitcase.

The older sister confesses, and Ron compels her to drown herself in the river. Totomaru first holds Ron back and tells Amamiya to go after the older sister, but when she escapes Amamiya's grasp, Totomaru jumps after her himself and saves her.

Later, Toto heads to the Metropolitan Police Department where Amamiya informs him that they found a fragment of the piggy bank in the stalker's hair and his fingerprints and blood in the sisters' living room. As the older sister acted out of self-defense, she will likely receive a lenient punishment. Amamiya then scolds Toto for bringing an outsider to the crime scene and demands to know his name. However, as soon as Toto tells her that his name is "Kamoo," Amamiya lets the matter go.

Afterward, Toto returns to the Maison du Kamonohashi to see Ron. Ron praises Toto's performance and declares the day "Puppet Establishment Day."

### Benizome Hot Springs Murder Case

When Ron calls Totomaru, saying that he needs his "help," Totomaru immediately hurries to his aid as he believes that BLUE is after his life. However, when he arrives at the supermarket, he learns that Ron only needs his help paying for his groceries as the cashier does not allow him to open a tab. After Toto pays, Ron receives a lottery ticket and wins a weekend trip to the Benizome Hot Springs for two people.

Later, they head to the Benizome Annex where they are greeted by Spitz Feier. Toto and Ron immediately go to the men's bath, and Ron tells Toto about a legend he read in the pamphlet they received from their taxi driver: Apparently, the hot springs received its name after a girl was sacrificed and her blood dyed the water red.

Afterward, Toto and Ron play ping-pong, and when they lose their ball and wade, in vain, to find it, they return to the men's bath to warm themselves up. A moment later, Amamiya enters the men's bath and quickly leaves when she realizes her mistake. That evening, Ron and Toto play *The Game of Life* with a few other guests—Michiyo and Sachiko's husband—in the Crimson Room until 2 a.m. Amamiya is not present because she went to bed early.

The next morning, a staff member discovers a corpse in the women's bath: It is Sachiko who went to the bath alone at around 10 p.m. Suspicion immediately falls on Amamiya because she is the only one without an alibi, but Ron declares that she cannot be the culprit, and that Toto will prove it. "Toto" already deduced that the murder was modelled after the Benizome legend; Amamiya does not know it and, thus, could not have committed the crime.

Michiyo testifies that she saw mist rising from the river after dinner, and Ron discovers the lost ping-pong ball in a dam created from leaves, branches, and a rain gutter. After he and Toto also find a bathmat, and Amamiya reminds them about the embarrassing run-in, Ron solves the case.

After Toto and Ron discuss the case in their room, they gather everyone in the women's bath, and Toto reveals what happened: Sachiko was killed by her husband. He redirected the river's cold water into the women's bath, placed a bathmat over the bath's entrance, and put red leaves in the water. When Sachiko entered the bath, she tripped because of the mat and fell into the water; the sudden temperature change made her die of a heat shock. To set everything up, the husband switched the banners to the baths which is why Amamiya walked into the men's bath by accident.

When the husband confesses to the crime and that he cheated on Sachiko with Michiyo, Toto shouts at him for stealing his wife's life. He then realizes that Ron did not pressure the culprit as usual and looks around for Ron, only to watch him get dragged away by Spitz. Totomaru follows them into the forest where Spitz reveals that he is a BLUE instructor and was sent to find out whether Ron is engaging in any detective work. However, he assures Ron that he will lighten his punishment if he admits everything, but Ron sees through his ruse and the true reason why Spitz sought him out: He needs his help.

Spitz admits that he needs his help locating his missing brother. Ron declines as he does not trust him, but Toto vouches for Spitz. Touched by his effort, Spitz says he will do his best to gain their trust before he leaves. Ron then notes that Spitz might be useful in the future.

### Hand Collector Killer Case

Amamiya informs Toto that she chose him to work with Omito Kawasemi on the Hand Collector Killer Case as it is a collaborative investigation between the Metropolitan Police Department and the Aichi Prefectural Police. Toto is thrilled at first, but his excitement quickly wanes when Kawasemi arrives, points out everyone's mistakes in the department, and labels Toto as having "zero talent" and unsuited to be a detective. Thereafter, Toto, Kawasemi, and Yamane head to the crime scene.

At the Tokyo Central Art Museum, Yamane tells Kawasemi and Toto that a truck driver brought some sculptures here from the Aichi Prefecture, and when he unloaded them, he noticed that one of them is a corpse. When Kawasemi sees that the culprit cut off the man's hands, he notes that it is "the same M.O." but does neither elaborate nor pay attention to Toto who wants to know more and help. Ron then invades the crime scene, disguised as "Kamomi Tekemono," a hand puppeteer and consultant for hand-related cases. He could locate Toto because he had Spitz track Toto's phone for him. Although Kawasemi is displeased by Ron's presence, he reluctantly allows him to stay as he does not seem to be a "half-assed" civilian, at least.

Toto tells Ron about Kawasemi's accomplishments which causes him to become jealous and determined to solve the case before Kawasemi. Ron then forces Yamane to brief them: The Hand Collector is notorious for stabbing his victims in the heart and, as his name implies, cutting off their hands. Last night, Yamane and Kawasemi could corner the Collector, but he managed to tackle Kawasemi and run away. Curiously, the dead man that was discovered in the transporter is the man they thought to be the Hand Collector.

Excited, Ron goes to examine the corpse and notes the body's under-dressed state and the tattoo on the arm stump. Yamane clarifies that it is a bird tattoo and that he saw it last night while handcuffing him. Ron then tricks Kawasemi and tests his reaction time: He could effortlessly dodge Toto and, thus, must be lying: The killer could not have easily tackled him.

Kawasemi admits that he was lying, but only to shield Yamane. He was there when the culprit escaped, and Kawasemi realized that the situation must be unsettling Yamane: After all, a button was missing from his orderly partner's sleeve. Ron then points out that Yamane is missing a button again which sends him into a panic; only when Ron says he has it, does Yamane calm down, relieved to know that it is "here this time." Hearing his words, Ron solves the case.

Afterward, Spitz calls from the room of the corpse in the truck, Minoru Mushanokoji. He found the three victims' hands in a fridge, proving that Mushanokoji is indeed the Hand Collector. Ron then tells Toto his deduction to present Kawasemi and Yamane: Mushanokoji committed suicide last night after Yamane and Kawasemi cornered him. Yamane found the body and removed Mushanokoji's blood-stained jacket, cut off his hands, and placed him in the truck so that he could report that Mushanokoji ran off with the handcuffs. In reality, Yamane had lost them but was too frightened of Kawasemi to admit it. Kawasemi is horrified and apologizes to Yamane for putting so much pressure on him.

Kawasemi later approaches Toto and Ron: He has seen through their relationship, and it made him see Toto in a new light because Ron can only display his abilities with Toto's help. Kawasemi adds that he is looking forward to their next joint case—which he will solve, not them. Ron, on Totomaru's behalf, accepts the challenge which frustrates Totomaru.

### Live Broadcast Murder Case

Totomaru visits Ron who recently purchases and television and is now binge-watching shows. His favorite show, "Lie or Truth? ESP!!," will air now, and Ron invites Totomaru to watch it with him.

In today's episode, genius neurosurgeon Mofu Usaki faces off against self-proclaimed ESP Dankichi Torage. Torage claims that he can control someone's brain by only using writing. He picks a volunteer from the audience, and after the host Onoyako puts voice-cancelling headphones on him, Torage begins to write words on panels. He holds them up; as soon as the volunteer reads the command, his brain will obey and execute the order, and the man will be unable to fight back. And indeed, it seems to work: The volunteer jumps and runs when he reads the words on the panels. Mofu objects, saying that she analyzed the man's movements and found out that he is the same volunteer Torage chose the last time. This means they are working together, and the demonstration is a farce.

This enrages Torage and, to prove her wrong, he writes "death" on the next panel. When the volunteer reads the word, he collapses. Torage checks his pulse and pronounces him dead right before the live broadcast is cut off.

Toto and Ron hurry to Donut Television; because everyone else is busy, Amamiya assigns the case to Toto. At the studio, Ron examines the corpse and gets an autograph from Torage (oddly, he uses the thick end of his marker to write his name) before he and Totomaru speak to Mofu. She tells them that the volunteer was killed with a nerve poison, and Ron agrees, saying that he spotted a puncture wound on the victim's neck that must have come from the poison needle. Mofu also informs Ron and Toto that the victim let out a groan when she massaged his heart; his breathing stopped again right afterward. This is the final piece of information that allows Ron to solve the case.

Toto and Ron then gather everyone, and Toto announces that they will re-enact what happened earlier. Mofu will be the test subject this time, and Toto will use Torage's marker and cards. When Torage is reluctant to hand the marker over, Mofu goes to get it from him and trips in the process. The marker lands in-between other pens, and Mofu picks it up.

During the re-enactment, everything happens like it did before—Mofu even collapses when she sees the final word. Toto reassures everyone that she is not dead: When he showed the panel to the audience, it read "death." Before he showed it to Mofu though, he turned it upside down. "Death" turned into "sleep." The same occurred earlier, and when Torage checked the sleeping volunteer's pulse, he killed him with the poison needle he hid in his marker. Torage confesses that the volunteer was his assistant who was threatening to expose him if he did not give him 90% of his profits.

While Totomaru yells at Torage for killing his accomplice, Kill on Sight activates and Ron pressures Torage to stab himself with his marker. When Toto rushes to save him, the tip touches his skin which sends him into a panic, but they quickly realize that Mofu picked up the wrong marker earlier. However, the incident still shakes up Ron and he hurries out of the studio. Toto follows him, and when Ron says that he regrets resuming his detective work because Toto nearly died because of him, Toto wonders if they should continue with their teamwork. Toto then spots Mofu whose bandage got stuck on a handrail. He helps her, and Mofu thanks him for today and remarks that his "brilliant deduction" is going to save many lives. This reassures Toto to keep working with Ron, and Toto runs after Ron.

Toto finds Ron outside Donut Television. He convinces him not to quit, saying that he will not die that easily and that he believes in Ron. Then, Toto surprisingly receives an invitation to a party at the Nandan Observatory on Nandan Island. As soon as Ron sees the invitation, he wants to come along.

### Island Observatory Murder Case

Ron tells Toto that he wants to accompany him because Nandan Island is famous for its brown sugar syrup; he also wants to distance himself from cases for a while. Toto agrees to take him along.

Three days later, the observatory director Takumi Jumonji drives Toto and Ron on a boat to the island. He informs them that he invited Totomaru as a security measure because, ten years ago, there was a terrible incident at the observatory. However, before Jumonji can elaborate, Ron cuts him off, not wanting to hear anything about any cases.

Not long afterward, they arrive and head to the observatory. Jumonji shows Toto and Ron around and explains that there is a model gun in the lobby to repel evil spirits. When they go to the observation dome, they hear the cook Minami Unno screaming that she will kill someone; she does this regularly to relieve stress because the closed-off dome is perfectly soundproof.

Then, the other guests join them in the dome: Eisaku Donzawa, Kayoko Onodera, and John Grizzly. Ron immediately recognizes Grizzly and wonders why a BLUE instructor is acting as a bodyguard at a party. Grizzly educates him and Toto about the Nandan Observatory Murder Case: Ten years ago, a viewing party for the same meteor shower they will be watching today was held. The party ended with the director at that time, Jumonji's father, and six guests shot in the dome. Neither the murder weapon nor the culprit was ever found. Jumonji adds that he is holding a "re-do" party to "overcome" that tragedy. While everyone cheers for him, the last guest, Princess Ori, arrives, and Ron flips the lever to open the dome. Everyone then watches the dome open and the telescope turn.

At night, everyone gathers on the roof for the meteor viewing and the standing buffet party. During the party, Onodera and Donzawa tell Toto that Ron possesses vast knowledge of astronomy, and Ron explains that he got interested in astronomy because his famous detective ancestor did not know anything about that subject. Hearing this, Toto realizes that he does not know much about Ron's past and he, thus, decides to seek out Grizzly to find out more about the Bloody Field Trip Case and Ron's illness.

Princess Ori then tells Totomaru that he has to stop Ron he is about to hula hoop although he ate too much. Totomaru tries to stop him, but Ron quickly finishes hula-hooping and then heads to bed early. Toto remains on the roof and later watches the meteor shower which brings him to tears with its beauty. Afterward, he remembers that he has not seen Onodera for a while. Donzawa informs him that she went back to her room to get some photography equipment, but that was two hours ago. Then, the dome moves and a gunshot is heard from inside it.

Immediately, Toto and the others run to the observation dome. Because the door is locked and Jumonji cannot find the master key, Toto, Jumonji, and Grizzly need to break the door open. On Jumonji's order, Unno brings flashlights, and when they search the room, they find Ron with a gun beside him and Onodera's corpse on the other side of the room. Princess Ori screams at the sight of the body which wakes Ron up. He testifies that he does not remember anything after going to bed. Because the other guests cannot be ruled out as suspects, Toto and Grizzly begin investigating.

After they inspect the room, Grizzly concludes that only Ron could have murdered Onodera as it was a perfect locked room situation. Surprised, Ron sits up because he did not know that the door had been locked; in the process, he discovers the missing master key in his pocket. Grizzly, subsequently, orders Toto to arrest Ron, though he should bring him his boots first; otherwise, Ron might cut himself on the glass shards covering the ground. Toto wants to protest, but, to his surprise, Ron does not want to fight the accusation at all.

Toto brings Ron to a storage room and handcuffs him to a pipe. He asks him if he really cannot remember anything, and Ron affirms. Toto then shifts the conversation to the Bloody Field Trip Case and asks Ron if the situation now feels like the situation then. Ron replies that it does, and when Ron gives up, believing that he must have killed Onodera, Toto reminds him that he could not have killed her. After all, he only pressures murderers to death, and Onodera was an innocent person. His words slightly unfreeze Ron's brain, and he remembers that he is, actually, a terrible shot. He could not have possibly shot Onodera through the heart from behind. Wanting to find the real culprit, Totomaru hurries out.

Toto re-examines the observation dome and notes how precisely all the lights were shot out, meaning that Ron could not have done that. He also remembers that he heard only one gunshot and that the telescope is always recording. And while Toto looks through the telescope data, Grizzly arrives with a stepladder as he wants to inspect the room and the data as well.

Although they have opposite goals, Grizzly gives Toto everyone's testimonies: Onodera went to her room shortly after 11 p.m. and was killed at 1 a.m. And because the others all have alibis for that timeframe—Jumonji was at his office from 11:30 to midnight, Donzawa only briefly left the roof to go to the restroom, Unno was in the kitchen from 11 p.m. to 1 a.m. taking to Ori who got something to drink after broadcasting a performance from midnight to 12:40—only Ron could be the culprit. Still, Toto insists that Ron did not kill Onodera because Ron is his friend and he knows him. He then shows Grizzly his findings, and when Grizzly sees the telescope data, he realizes that Ron is indeed not the killer. He gives Toto the key to Ron's handcuffs and remarks they need to hurry to capture the culprit before they kill again.

Totomaru returns to the storage room to free Ron. Ron praises him for being able to prove his innocence. However, because Toto does not understand how exactly he did that, Ron explains it to him: Onodera was killed at 1 a.m., but all seven lights in the dome were shot out before 11 p.m.; the telescope recordings proved this. Thus, at the time of Onodera's murder, the floor was already covered in glass shards. As Ron's feet were not cut when he was found, he could not have taken a single step after 11 p.m., and Ron could impossibly have shot Onodera with the telescope between them.

Ron adds that someone must have laced his brown sugar meal with sleeping medicine to ensure that he would retire to bed early. Everyone could have done this though, and not just Unno.

Back in their room, Ron drinks multiple syrup packs to bring his brain back to full functionality, and Totomaru informs him that Grizzly promised to reopen the Bloody Field Trip Case investigation. A moment later, they hear a gunshot and see Grizzly falling past their window. They hurry outside but can only confirm his death.

Ron inspects Grizzly's body and retrieves the fishing line he is clutching right before Jumonji and Donzawa, who carries an umbrella, join them; they heard the gunshot and wanted to find out what happened. Toto then gathers everyone in the lobby for a general breakdown of the events: Grizzly was shot with the same gun as Onodera, meaning that the killer must have taken it from him.

Furthermore, because none of the guests have an alibi (they were either alone or asleep), they are all suspects. Thereafter, Toto and Ron return to the observation dome for further inspection, and Toto tells Ron what happened earlier. They examine the door and discover glue on its sides; they also realize that Onodera is lying right in front of the dome switch. Because the dome opened right before Toto and the others heard the gunshot, Onodera might have flipped the switch before her death. Toto does not know what to make of the situation; in his eyes, nobody could have committed the crime. Ron, however, manages to solve the locked room mystery, though he does not know who the culprit is.

At this moment, Princess Ori approaches them to inquire if they know where the flashlights are. She asked Unno already, but Unno told her to get them herself, annoyed to be requested to fetch the flashlights a third time. This piece of information is the final puzzle piece that Ron needs to solve the case completely, and he thanks Princess Ori for giving him it.

After everyone comes together in the observation dome, Totomaru reveals that Jumonji is the culprit: Jumonji immediately found Grizzly's corpse, although he could not have known its location if he had only heard a gunshot. He also ran outside without an umbrella to cover up that he had already got wet earlier when he killed Grizzly. Furthermore, Jumonji had left the party early. During that time, he attacked Onodera, put her to sleep, and brought her to the dome with Ron. He slipped the master key into Ron's pocket and placed the model gun next to him before he connected the telescope and the trigger of a gun he hid inside the vent with a fishing line. Lastly, he sealed the door with glue.

Because Onodera only received a light dose of sleeping medicine, she woke up earlier than Ron. She tried to turn on the lights first, in vain, because they were destroyed beforehand. Onodera then went to open the door. When it did not budge because of the glue, she turned the key, but that only locked the door. Ultimately, she flipped the dome switch, and when the dome opened and the telescope turned, the gun's trigger was pulled and she was shot in the back. Jumonji later retrieved the gun from the vent and killed Grizzly with it.

Jumonji exposed himself when he told Unno to get the flashlights *before* they entered the observation dome. He would only know that they would need them if he had destroyed the lights. Jumonji confesses to having killed Onodera because she was actually a journalist who wanted to reveal the truth behind the Nandan Observatory Murder Case: Jumonji's father killed the guests before committing suicide. Jumonji then hid the murder weapon to cover up his family's shame.

Hearing his confession, Kill on Sight activates, and Ron orders Jumonji to shoot himself. Toto stops Ron before the ability takes hold of Jumonji, but Jumonji swallows a cyanide capsule. With his dying breath, he tells Ron that he will never escape "his" grasp.

Toto confirms Jumonji's death before he and everyone but Ron head to the lobby. He calls the local police and later guides them to the observation dome. When the investigation is over, Toto speaks with Ron in the lobby; he informs him that the police left with the bodies and that they can leave now too.

Ron tells Toto that he retracts his words about giving up on detective work: Earlier, he opened the dome again, and when the room was lit up, the "96"-mark under Onodera's corpse became visible. This indicates that this case purposefully felt like the Bloody Field Trip Case and that both cases were orchestrated by the same people. Ron declares that he will never forgive them; at the same time, he is excited to have his personal mystery now. He asks Toto if he will continue to help him, and Toto affirms.

### Poisoned Latté Case

Toto visits Ron and helps him with his gigantic futon. Afterward, they discuss the events of the Island Observatory Murder Case and the fact that the boat which carried the corpses of Grizzly, Onodera, and Jumonji sank and the entire crew went missing. Whoever gave Ron his "96"-scar must have been responsible for this as well.

Toto then heads to work where Amamiya informs him that she has a job prepared for him and sends him to a conference room. There, Chicory Monki is awaiting him. She wants to feature him in the "person of note" section in Lime Weekly's next issue which surprises Totomaru, as the section normally highlights entertainers or athletes. Chicory explains that she chose him because she admires detectives and has heard of the recent cases "he" solved. Although the situation weirds him out, Toto agrees to her request to shadow him all day nevertheless.

After work, he and Chicory go to Pot Coffee to do a quick interview. To Toto's surprise, Ron is working there; he explains that he has been doing shifts there ever since he taught the shop's owner how to make his special brown sugar latté. Ron takes Toto's and Chicory's orders as well as the ones from Hayami, Julie, and Tamada who arrive shortly afterward. Ron quickly prepares everyone's drinks; he decorates the lattés with platypuses and gets offended when Hayami calls them ducks while picking up her order.

When Ron learns that Chicory is a crime reporter, he tries to get into her good graces; after all, Chicory could be a valuable source of information for difficult cases. However, Ron's attempts do not only bother Totomaru but also annoy Chicory. A moment later, Julie dies after drinking a poisoned latté.

The ambulance and police arrive, and Ron is about to inspect the corpse when Chicory interrupts him. To Toto's dismay, she urges Ron to leave and make room for Toto, "the famous detective" who will definitely solve the case while she records everything.

Toto then interviews the suspects, among them Ron as he has prepared the drinks. Hayami brought the lattés to their table, and right after she and her friends took a group photo with the drinks, she excused herself, having received a call. Julie left the table too to take more photos; during that time, Tamada was the one watching the drinks. When they all came together again, Julie picked the first cup and then collapsed after drinking it. Ron points out that, considering the chain of events, he, Hayami, and Tamada all had an equal opportunity to poison Julie. Totomaru objects because Ron could not have possibly known which latté Julie would choose; he also has no motive for indiscriminate murder. Ron praises Toto's improved deduction skills, and Tamada informs them that Julie took the latté that was the farthest away from her.

Toto, Ron, and Chicory then check Julie's social media posts and the pictures Chicory took earlier. They find a picture of the three lattés right after Ron finished them and the group picture in which Julie poses with her latté. Toto frantically scrolls through the pictures trying to figure out what happened when Ron offers him a jumbo-sized hot towel with the Pot Coffee logo on it, saying that it might be a hit on social media. Toto replies that it might stand out for the wrong reasons; Ron tells him this is the key before he pushes his hair to the side, indicating that he solved the case.

After Ron lets Toto in on the mystery, Toto calls everyone together: Hayami killed Julie. She poisoned one latté and scratched the platypus art on the other two, knowing that Julie would choose the poisoned one as it was the best-looking one. "Toto" figured this out after comparing Chicory's photo to the group picture.

Hayami admits her crime; she killed Julie because she always wanted to be the center of attention and stole Hayami's boyfriend when he got scouted by a talent agency. Ron then pressures Hayami to smash her head on a teapot sculpture, though Toto can save her on time by grabbing a sack of coffee beans and hauling it between Hayami and the sculpture. In the process, Toto accidentally knocks Chicory's recorder from her hands, breaking it. He apologizes for that afterward, but she is not upset at all because she could see him in action. She realized that he was not like how she imagined him; he may not be a quickwitted detective, but he is amazing nonetheless because of how devoted he is to all he does.

Afterward, Ron makes Chicory and Toto more lattés on which he writes "You did it!!", "Got 'em!!", and "Reporter Connections." Toto stirs them before showing them to Chicory.

### Sandbox Murder at Dawn Case

At 6 a.m., Toto comes to the Maison du Kamonohashi to tell Ron that he does not have any cases for him. This immensely disappoints Ron as he is so bored that he even tried engaging the dead ants in conversation which scares Toto. Still, Ron thanks Totomaru for his hard work, as he can see that he must have done paperwork all night. Totomaru confirms this and adds that he worked so hard that he hallucinated when he walked past a park at dawn: A "strange blue thing" hovered in the air for a moment before disappearing.

Intrigued by this "hallucination," Ron drags Toto to the park. There, they discover a tomb in the sandbox, and when Toto digs there, he finds the corpse of Tatsuo Kinoshita. They call the police, and the body is examined: Kinoshita died of suffocation at 3 a.m.

Just past 7 a.m., Kinoshita's friends Tetsu Yamada and Hajime Satou arrive and are questioned. According to the writing in the sandbox ("I was killed by Tetsu Yamada"), Yamada is Kinoshita's murderer; his shoes are even full of dirt and sand. However, Yamada has an alibi: He was home from midnight onward, watching a movie with friends who can attest to his claim. He only came out now to take out the trash.

Toto has no idea what could have happened, he is sleep-deprived and hallucinating, and instead of helping Ron is chatting with ants and getting upset over an antlion trap. Ron, however, assures him that he did not hallucinate because it is "all connected." He then entrusts Toto with his deductions.

Thereafter, Totomaru and Ron gather Yamada, Satou, and the other police officers so that Totomaru can present Ron's deduction: Yamada killed Kinoshita. He drugged Kinoshita before midnight and brought him to the park where he buried him in the sandbox, but left the space around his head free of sand. Yamada ran a hose through the sand to provide him with air and covered Kinoshita's head with a sheet. In its middle was a hole, and Yamada put sand on top of the sheet, turning it into an antlion trap: The sand slowly fell through the hole and onto Kinoshita's head. The sand gradually covered his head, and Kinoshita died of asphyxiation hours later. Yamada also tied a string to the sheet to pull it away while he was still at home. Having created a "perfect" alibi, Yamada dared to write "I was killed by Tetsu Yamada" into the sand to ensure that he would get questioned early before his testimony fell apart.

Yamada confesses that he killed Kinoshita because he flirted with his girlfriend Mika. His words trigger Ron's Kill on Sight ability, and Ron persuades Yamada to stab himself with a broken bottle, but Toto can stop him. After Yamada is arrested, Toto asks Ron how he knew that he did not hallucinate and that a case was behind the "flying blue object." Ron replies that Toto can withstand a single all-nighter and that he is not naive enough to hallucinate.

### Mad Chameleon Murder Case

Amamiya sends Toto to Nagoya to make a report on regional crime patterns; while he is there, Toto should also check up on Kawasemi who has been in a slump since he lost Yamane. For a moment, Toto believes that Amamiya might be worried about Kawasemi. He changes his opinion when she gets excited about the "death throes" of Kawasemi's career.

Totomaru informs Ron about this on the train to the Aichi Prefecture. Though Ron claims he is only coming because, if Kawasemi was unable to solve any cases lately, there would be more for him, Totomaru is sure that he is actually concerned for Kawasemi. Ron says he considered this too, but he never cared about someone else's feelings, at least in his student days. He does, however, acknowledge Toto as his friend.

Later, when Toto is in front of the Aichi Prefectural Police's headquarters, he receives a message from Ron: Something urgent came up and Toto should meet up with Kawasemi alone; he will join them later. Toto then goes to look for Kawasemi and finds him accidentally lecturing an undercover officer about his appearance and asking another officer for his name although he gave it already. Afterward, Kawasemi spots Toto, and they head to a restaurant to catch up. Kawasemi admits that he is indeed in a major slump. Because it is already so late, they go shopping for souvenirs; Toto gets a lot for his grandmother.

While Toto and Kawasemi walk around in the shopping center, he spots a sign that warns passersby about the Mad Chameleon. Kawasemi explains that someone is attacking students during the day with a wrench and stealing their smartphones. Because no victim described the culprit the same way, they were dubbed the "Mad Chameleon." A moment later, they witness a Mad Chameleon attack. Totomaru chases after them, whereas Kawasemi tends to the victim. Toto sees the Mad Chameleon elbowing a woman right before escaping into a clothing store around the corner.

Totomaru gathers everyone in the store and lines them up for inspection. Kawasemi later joins Toto and tells him that the victim died. Angered that the Mad Chameleon crossed the line, Kawasemi examines the five suspects but cannot see anything. Just then, Ron calls Toto, and Toto gives him the details on the Mad Chameleon Murder Case. Ron is certain that the culprit is not using a disguise. He adds that he will go to them and that they should wait for him.

Toto and Kawasemi then speak to a police officer. Because the culprit disguised himself well, the security cameras could not get a clear image of his face. However, they could discern from the angle of the wench wound on the victim's head that the Mad Chameleon is at least 5'6" which narrows down the five suspects to three. Kawasemi re-examines them, and when this attempt proves unsuccessful again, he lets the suspects go; their contact information was already recorded.

Thereafter, Ron arrives in handcuffs as the police considered him a "suspicious person" and arrested him. Only when Kawasemi informs them that Ron is a crime consultant, he is set free. Ron asks why the victim, a student, was wearing a suit. Kawasemi tells him that he must have been at a job interview and that all of the Mad Chameleon's victims had been wearing suits.

Ron remarks that they must be hiding something; after all, nobody can fully change their appearance. While Toto does not know what he means, Kawasemi immediately understands it: The "It's Me!" scam in which fraudsters dress in suits and impersonate bank workers to gain the trust of their targets. All victims are receivers in the scam and they lied to hide their connection to the fraud ring as the Mad Chameleon is part of it as well. The victims' phones were stolen to get rid of any evidence of their contact with the fraud ring.

With the mystery solved, they only need to identify and catch the culprit. Ron insists that only Kawasemi can do it; when Kawasemi persists that he cannot, Ron vexes him until he breaks Kawasemi out of his slump. He then makes him think about the suspects, and Kawasemi immediately "sees" the answer: The culprit did not elbow anyone; he checked his watch because of the sign announcing the time of the road closure. He thought he still had time because he was wearing a watch that showed the incorrect time. Because of that, he had to hide in the shop.

As the Mad Chameleon gave the police the wrong contact information, they need to wait for him to return for the stolen smartphone that he had hidden in the shop. Ron points out that the phone is right in front of them and is "making a call."

Later, while Toto and Ron are on their way home, Kawasemi catches the Mad Chameleon and calls Toto to inform them about his success. The culprit's watch was off because he partied in Singapore until yesterday. Then, Toto asks Ron about his "urgent matter" from earlier, and Ron tells him that he was examined for his "pathological culprit killing" and that, according to his test results, the doctors might be able to lessen the symptoms.

One week later, Amamiya notifies Totomaru that Kawasemi cross-examined all the victims in the Mad Chameleon Case, and they told him about the fraud ring. He is now about to uncover the ring's headquarters, and his arrest rate is even higher than before—a fact that enrages Amamiya and leads her to yell at Toto for giving him a boost.

### Yadagami-sama Murders Case

Toto is heading home from work when Ron calls to ask for his opinion as he is unsure whether to help Spitz find his missing brother. Toto tells him that they should help him; after all, Spitz has been assisting them with their investigation. Ron then informs Toto that Spitz has been tailing him, and Toto looks around and spots Spitz standing on a roof.

Together, they head to Ron's now partially furnished apartment. After Toto notes that Spitz looks rather crestfallen today, Ron reveals that he agreed to help Spitz but only if he steals BLUE's file on the Bloody Field Trip Case. This angers Toto, and he scolds Ron for pressuring Spitz into committing a crime. After all, they should help Spitz without demanding anything simply because he is their friend. Toto's words move Spitz, and he accepts Ron's condition. Immediately afterward, they travel to Yada Village in the Yamanashi Prefecture.

On the way, Spitz imparts that his brother was an anthropologist; he vanished eleven years ago when he took Spitz to Yada Village for research. They also discover a waterfall and spot a a woman standing by a shrine. A moment later, a villager throws an axe and nearly hits Toto. After the man apologizes, Toto, Ron, and Spitz continue their journey.

At Yada Village, the mayor and various villagers protest against a surveyor who wants to evict the entire village to build a dam. The villagers claim that this will anger Yadagami-sama, the god protecting their village. After the surveyor leaves, the mayor invites Totomaru, Ron, and Spitz to stay at his house. He guides them there, and when they arrive, they meet the woman from the waterfall who turns out to be the mayor's granddaughter Mii.

Later, Toto, Spitz, and Ron have dinner in their room. Spitz gives them more information on his brother's disappearance: After questioning the villagers all day about the Yadagami Legend, he and his brother went to bed. The next morning, his brother was gone, and although everyone, including the police, thoroughly searched the village, Shepherd Feier could not be located.

At some point, Toto looks out of the window and sees a gigantic snake wrapped around the surveyor who is staying in the mayor's hut on the other side of the river. Immediately, he, Ron, and Spitz hurry to the hut where they only hear a bang and find neither a snake nor the surveyor inside. The following morning, the surveyor is discovered strangled in the waterfall basin outside Yada Village.

After the local police arrive, they, Toto, Ron, and Spitz inspect the crime scene. The surveyor, apparently, did not die from strangulation; he died when he hit his head falling into the basin. Then, the mayor and Mii come, and the mayor claims that Yadagami-sama killed the surveyor. Ron asks Mii what she was doing by the waterfall yesterday, and Mii explains that she was making an offering to Yadagami-sama.

Thereafter, Totomaru, Spitz, and Ron walk to the hut and meet Muroi on the way. He tells them that Yadagami-sama is a living legend as there are still reports about its "power of disappearance." For example, the god made machinery vanish 15 years ago, and Shepherd Feier disappeared as well. Muroi also reports that he once fell asleep in the mountains, only to wake up at its foot. When Ron inquires about his whereabouts yesterday, he testifies that he was at the Yadagami Shrine to see the objects there, but it was closed.

When they arrive at the hut, the police officer tells Toto, Ron, and Spitz that they have found nothing suspicious except for a bottle of brown sugar which Ron recognizes as the one he lost yesterday. Disheartened, Spitz goes to the window—and spots a white snake in the river. However, when Toto and Ron look outside, they see nothing. Considering the "snake" Spitz saw and the fact that the stain the brown sugar bottle left is not where the bottle currently is, Ron solves the case.

They then gather everyone by the waterfall, and Totomaru explains what happened: The mayor strangled the surveyor with a rope from the shrine and threw him into the basin. He placed a picture of a snake curled around a man in the hut and attached it to a tatami mat. It was held up upright with a string; one end was tied to a rock that was dangled out of the window, the other pinched in the front door's frame. When Ron, Toto, and Spitz arrived and opened the door, the mat fell, made a "bam" sound, and Yadagami-sama "vanished." The rock and the string tumbled into the river, and Spitz later assumed the string was a snake.

The picture is a scroll from the shrine; to hide its absence, the shrine was closed yesterday. The location of the brown sugar bottle and its stain did not match because the mayor lifted the mat to retrieve the scroll. Because this trick required witnesses to work, only the mayor could be the culprit: After all, he assigned Toto, Spitz, and Ron to that specific room.

As soon as the mayor confesses, Ron pressures him to fall into his death. However, when Toto tries to save the mayor, the ground gives up under them. Toto can hold onto a rock, and Ron, Mii, and Spitz pull him and the mayor up with a rope a mysterious person tossed them.

Following the mayor's arrest, Toto and the others return to the mayor's house. There, they encounter Shepherd Feier who has been hiding at Yada Village all along after becoming the target of a "certain" organization. Now, because the mayor killed the surveyor to protect him, Shepherd Feier does not want to hide anymore, as he cannot live at the expense of others' happiness. He, thus, asks Toto to arrest him. Ron then informs Shepherd Feier about Mii's feelings for him before he and Toto leave them and Spitz alone.

As promised, Spitz travels to BLUE to steal the Bloody Field Trip Case file. However, when he returns, he does not have the file with him but a message from Aimee Emmerich for them all—Ron, Toto, and Spitz: The lead Ron is searching for has been deleted from both the police's and BLUE's records; it concerned a bit of blood that belonged neither to Ron nor to any of the victims. And since Aimee learned about the Island Observatory Murder Case, she is sure that the Bloody Field Trip was orchestrated by the M. Family; they also gave Ron his Kill on Sight ability alongside his "96"-scar. Aimee adds that while she wants to help Ron, she cannot because there is an M. Family spy at BLUE.

After finishing Aimee's message, Ron declares that he will best the M. Family.

### Shibuya Revelation Serial Murders Case

One morning, Totomaru accompanies Amamiya to the Shibuya Mall Park to investigate a case. To his surprise, Ron is already there; he managed to get access to the crime scene by pretending that he has to deliver candy to Toto. Because Amamiya is upset that she is not subscribed to Kamonohashi Sweets when Toto is, Ron offers her a subscription which she fills out before they arrive by the body: The blindfolded, bound victim has been impaled by the horn of a unicorn statue. A plate saying "And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them" hangs from his neck. Amamiya wonders if it is some kind of poem, and Ron informs her that it is a verse from the Revelation of St. John.

Afterward, a police officer informs Toto and Amamiya that the victim died of blood loss at around 2 a.m. The security officer checked all floors before he switched on the anti-intrusion sensors at midnight; curiously, the sensors did not detect anything, and they are at a loss in how the murderer managed to escape the crime scene.

Meanwhile, Ron inspects the corpse and quickly solves the case. He passes his deduction to Toto so that he can present it to Amamiya: The culprit suspended the victim from the arch above the unicorn, and the victim had to hold onto the rope so that he would not fall into the horn. When his strength eventually left him, he let go of the rope and was impaled.

The victim is then identified: His name is Ryouji Katsunami and he belongs to a hacking group that recently committed a cryptocurrency theft. When Ron learns that the police discovered a burn mark on Katsunami's neck, Ron hurries to the corpse to check the spot. The mark reads "0 10:00." Ron tells Toto that the M. Family must be behind the murder and that this is a direct challenge to him: The burn mark is in the exact same location as his "96"-scar, and the Revelation quote is from Chapter 9, Verse 6. Furthermore, the numbers are announcing the next murder: Someone is hunting down all three members of the hacking group. "10:00" indicates that the next murder will happen at 10 a.m.—which is in thirty minutes.

Toto and Ron split up from Amamiya to find out what the "0" could mean and run into Chicory. Toto asks her if she knows a place nearby that has something to do with "0," and Chicory tells him about Platform 0 at the Shibuya Station Bus Terminal. Toto and Chicory immediately hurry there; however, Ron does not accompany them because he is unconvinced that this is the solution as the corners of the "0" are unconnected.

When Toto and Chicory arrive at the bus terminal five minutes before 10 a.m., Ron calls them: He figured out that the "0" refers to the scramble crossing; the missing corners stand for the areas where there is no pedestrian crossing paint. Toto and Chicory rush to the crossing, and they and Ron make it just in time. At exactly 10 a.m., the crossing is covered in smoke. When the smoke subsides, it reveals Hibino's corpse. He was pierced through his heart with an arrow bearing the mark "Δ 11:00."

The third hacker is also at the scramble crossing and when he sees Hibino's corpse, he runs away. Toto runs after him while Ron remains with the corpse. However, while Toto loses the third hacker, Spitz is fortunately able to catch him.

After Ron joins Toto and Spitz, the hacker tells them that he and the others were hired by someone called "Marry Ito." That person masterminded the cryptocurrency theft and is now killing the hackers he employed. "Marry Ito" then calls the hacker: If he wants to live, he has to bring the cold wallet with the stolen cryptocurrency to the Delta Hotel at 11 a.m. If he calls the police, their deal will end and he will die.

Hearing this, Ron concludes that the message on the arrow means the same: the Delta Hotel at 11 a.m. He persuades Toto to use the third hacker as bait to catch "Marry Ito," and Toto calls Amamiya to inform her about the plan. Afterward, Ron and the others head to the Delta Hotel where they meet Amamiya who has gathered and stationed officers around the hotel.

Toto and the third hacker hide in a hotel room, whereas Ron stays in the lobby to keep a close eye on everything. At 11 a.m., the third hacker receives a call from "Marry Ito" who tells him that they noticed the officers, meaning the deal is off. Hoping that he can still hand over the cold wallet to "Marry Ito" and secure his survival, the hacker runs into the lobby; Totomaru hurries after him. Ron then notices that the chandelier will fall just when the hacker passes under it. He points this out to Totomaru who manages to tackle the hacker on time. The chandelier, thus, falls without injuring anyone.

A moment later, music starts to play. Ron immediately recognizes it as Haydn's 96th Symphony and realizes that they have played right into the M. Family's hands: Haydn's 96th is also known as the "Miracle Symphony" because, during its first performance, a chandelier fell but did not hurt anybody—just like earlier. Toto relays this information to Amamiya. She then informs him and Ron that the tip of the arrow that killed Hibino is made of iridium. Afterward, she takes the third hacker to the Metropolitan Police Department. Spitz goes to check out the crossing again.

Meanwhile, Ron shows Toto that he found a tablet with the next announcement—"Ⓗ 12:00"—behind the hotel's music player and educates him that iridium is in group nine, period six of the periodic table. This, Haydn's 96th, and the Revelation quote from Chapter 9, Verse 6 indicate that all the crimes are connected to his "96"-scar. Ron is sure that, with the third hacker's safety guaranteed, the M. Family will now settle things with him. He and Toto then hurry to Shibuya City View Tower, the only place nearby with a heliport.

They go up to the heliport where they encounter the third hacker. He tells them that the police car was attacked, and he was brought to the tower by someone wearing a helmet. That man ordered him to give Ron and Toto a phone. As soon as the hacker hands it to them, "Marry Ito" calls: He says that Ron will taste "a detective's despair" at noon.

While Ron has no idea what "Marry Ito" could mean, he suddenly solves Hibino's murder: Hibino was not shot from afar; instead, he was stabbed at close-range with the arrow, and the culprit used e.g. a whip to make a "whooshing" sound. The culprit, therefore, must have been at the crossing. Ron then tears off the third hacker's face, exposing Winter Moriarty. He reveals that he has been suspicious of the hacker since "Marry Ito's" first call as it was oddly one-sided and the only reason they knew to go to the Delta Hotel. Until he figured out the scramble-crossing mystery, Ron also considered that the third hacker might be the culprit's assistant, not necessarily the culprit in disguise.

Shortly afterward, Ron checks the phone Winter gave him and sees that it is already noon. The screen on the opposite building then explodes, and Ron can only watch the scene in horror while Winter tells him that he cannot save anyone, particularly the third hacker and Amamiya as Winter strapped bombs around them that were set to explode at noon. Toto and Ron try to call Amamiya and realize that their phones are broken; they were destroyed by a magnet when they entered the tower. Furious, Totomaru attacks Winter, but Winter quickly beats him to the ground.

Winter keeps taunting Ron, and Ron insults them and the M. Family's methods in return. Although Winter longs to kill Ron, they decide against it as they are a Moriarty and, thus, have to engage Ron in "a battle of wits" and give him "a detective's despair." Hearing this phrase yet again, Ron realizes that Amamiya and the hacker are still alive: "A detective's despair" means being unable to solve a problem you could have solved, or being unable to save someone's life. This means that the problem can be solved; the explosion was, therefore, only a dummy and did not kill Amamiya and the hacker.

Frantically, Ron tries to figure out how to solve the problem, but cannot think of something. Only when Toto points out there was already an explosion at twelve, does Ron realize that it is not twelve yet: The explosion destroyed the opposite building's clock screen, and they can only rely on the phone Winter gave them—and it shows the wrong time. Winter reveals that it is, in fact, 11:55:42.

Ron tells Toto to search for anything related to "96," and Toto immediately looks at Ron's scar: Ron is the only thing related to "96" around. Thus, Amamiya and the hacker must be in the tower. Winter discloses that they are in the first-floor storage room. With only two minutes left, Totomaru tries to call the elevators, but they are both on the first floor. Winter is certain of their victory; however, when it turns 12 a.m. there is no explosion: Spitz listened to their conversation and could get to the storage room on time.

Ron then demands to know what the meaning of his "96"-scar is. Although Winter refuses to tell, their wording makes Ron work out that the "6" must stand for the "sixth Holmes generation." Irked, Winter deliberately triggers Ron's Kill on Sight ability by confessing to the Shibuya Revelation Serial Murders Case. Ron attempts to persuade them to jump off the roof; surprisingly, Winter can resist him though. They blow up the glass railing behind them and is about to flee when they receive a call from their brother and is shot down the roof.

Toto later goes to the Metro Police's headquarters where Amamiya notifies him that the third hacker committed suicide. She also tells him to verify the culprit in the morgue, but Winter's body was exchanged with another. Toto reports that to Ron and Spitz when he meets up with them at the Maison du Kamonohashi. Spitz tells them that he intercepted the final transmission and heard that someone called him "Winter." Ron muses if "Winter" is a codename and guesses that whoever called them, the one they called "brother," is the M. Family's leader. Ron becomes even more determined to take him down.

### Midsummer Beach Hut Drowning Case

On his way to visit Ron, Toto encounters Mofu who is moving into the Maison du Kamonohashi after she was kicked out of her condo. Together, they go to see Ron, and Mofu reveals that she has found a way to suppress Kill on Sight. However, because it requires Ron to take a dangerous combination of various medicines. Mofu only permits Ron to take it when she is around.

Mofu then receives a call from Shikada who reminds her that she has a surgery today. After she leaves, Totomaru suggests that Ron takes a break from solving cases. They decide to go to the beach and on their way out, they run into Mofu whose surgery was cancelled last-minute. Ron invites her to come along, and they all head to Natsukaze Beach.

There, they seek out the beach hut because Ron wants to buy shaved ice, but they sold out of shaved ice this morning. This sours Ron's mood, and Toto tries to cheer him up by suggesting doing another activity on his to-do list. Ron does not feel like swimming anymore though and when Mofu offers to do the activity in his stead, he lends her his platypus swim accessories. Mofu goes swimming while Toto remains behind with Ron.

They then overhear an argument between the beach hut owner and two surfers, and Ron drags Totomaru to the surfers when the argument is over. He tells them that Totomaru is a police officer and that he might help. The surfers impart that their friend Taku Manba got a stomachache after eating something from the beach hut yesterday. Last night, he went to confront the owner but never returned. Totomaru advises them to contact the local police, and a moment later, Ron notices Mofu waving to them: She has discovered a corpse by the rocks; the surfers immediately identify it as Manba, and Ron deduces that he was murdered.

After the local police arrive, Toto explains to an officer the situation, and Mofu informs him about the result of her autopsy: Manba went to speak to the beach hut owner at 10 p.m. after he got drunk with his friends and he drowned between 2 and 3 a.m. His hands are purplish red, but he is otherwise uninjured. The officer concludes that he must have tried to surf while drunk and subsequently drowned, but Ron objects: Not only is Manba wearing a dry suit for boaters or divers, but the suit is also too large for him, and his surfboard is still where he left it the day before.

Thereafter, Toto, Mofu, and Ron question the beach hut owner about what he did last night: He cleaned up the shop, went home, and then drank all night with friends. Although he acts highly suspiciously, they cannot simply arrest the owner. They then buy food from him and head to their beach chairs to eat and discuss the case.

Because Totomaru's yakisoba is burned and barely edible, Mofu goes to get it replaced but trips on the way and swallows a bit of salt. She notes that it is unusually salty, and after Ron tastes the sand as well, he solves the case.

Ron takes his Kill on Sight medication before he, Toto, and Mofu gather everyone. Toto then reveals what happened: The beach hut owner killed Manba. Manba passed out in front of his hut, and the owner dressed him in a dry suit and placed him on a raft which he had created by combining ice blocks with salt. For that reason, the sand is especially salty, and he has run out of ice despite there being barely anyone at the beach.

The dry suit would ensure that Manba would not get chilblains or marks from the rope that tied him to the raft. The beach hut owner then pushed Manba on the raft into the ocean. Manba woke up when the ice melted, and drowned when it was fully gone. Because he had clung to the raft, he got chilblains on his hands. Furthermore, the hut owner's fingerprints were found on the surfboards outside the inn where Manba and his friends were staying; he left them there when he tried to take Manba's. He murdered Manba because he had already received three complaints of food poisoning; if Manba had reported him too, the health bureau would have closed his shop.

The beach hut owner confesses, and because of the medicine, Ron does not compel him to commit suicide. Toto and Mofu are happy that it worked, but the joy is short-lived: Ron suddenly calls Toto and Mofu "Max" and "Molly" before he passes out.

The next day, Totomaru visits Ron, and Ron tells him that Max and Molly were his childhood friends. Totomaru informs him that the medication's side effects include losing one's consciousness and experiencing memories of the past. He also requested that she allows Ron to take the medicine in Toto's presence as well, and Mofu gave her permission.

### Genius Composer Kidnapping Case

Three days later, Totomaru takes Ron to a Nyo-Nyon concert after his friend Higuchi got them platinum tickets for it. On the way to the venue, they talk about the talent kidnapper Hummingbird because he recently kidnapped the sculptor Masatatsu Oyama: Hummingbird always sends calling cards to his targets, and although the police put great effort into protecting the targets, Hummingbird is always able to outmaneuver them. Curiously, Hummingbird never asks for ransom; he simply wants his abductees to demonstrate their talent to him.

When they arrive at the venue, Ron spots a man with a mask and sunglasses who simultaneously watches two videos—one about first-class ballet, the other about a master craftsman—on two different smartphones and has two different earpieces in each ear. Ron asks the man if he can guess his occupation, and when the man allows it, Ron deduces that he is Hummingbird—or, rather, a wealthy heir who admires him. Totomaru apologizes for Ron's behavior and ushers him inside.

The concert brings Toto to tears. Afterward, Higuchi approaches him and Ron and asks for their assistance because Hummingbird sent a calling card to Nyo-Nyon. Because Toto provided primary help to Nyo-Nyon, he is requested to protect her on the day of the announced kidnapping, alongside the Metropolitan Police Department's Special Crimes Division under Namazu.

To Toto's surprise, Ron was also called by Nyo-Nyon. Namazu is suspicious of Ron, but before he can check his ID, the Yamanashi Prefecture Police under Sannou arrives as the mansion is on the border of Tokyo and Yamanashi and they also received a calling card from Hummingbird. Begrudgingly, Namazu agrees to cooperate with the Yamanashi Police.

Inside the mansion, Nyo-Nyon tells them about the building's history: A fire destroyed the original building, sans the clock tower. For that reason, she has installed smoke detectors all over the mansion. Sannou then suggests keeping Nyo-Nyon in a place where nobody could reach her, and Nyo-Nyon takes everyone to her composition room on the top of the clock tower. Namazu agrees to let her stay there.

Mitsubashi, Nyo-Nyon's manager, locks the staircase door, and everyone heads to wait in the living room. An hour later, the smoke alarm is set off, announcing a fire in the living room although there is none. Immediately, everyone hurries to the composition room, but Nyo-Nyon has already vanished.

Namazu goes to contact his subordinates at the base of the hill while Mitsubashi shows Toto, Ron, and Sannou around the lower rooms. In the storage room, Mitsubashi notices that the curtain is gone, and Toto and Ron ask her a few questions regarding Nyo-Nyon's work. Although she claims not to know anything about music, Mitsubashi's word choices indicate that she is actually knowledgeable in this area.

Afterward, they return to the living room, and Sannou announces that he has solved the case. However, he only wants to tell his deduction when Namazu returns. While they wait, Toto informs Ron that none of Hummingbird's victims filed criminal reports after their abductions. Ron then asks Toto to contact Chicory as he wants her to look into something for him.

When Namazu returns, Sannou says that he believes Mitsubashi to be Nyo-Nyon's kidnapper: Nyo-Nyon ran downstairs upon hearing the smoke detectors and pressed herself behind the locked staircase door, frozen in fear. Earlier, Mitsubashi took longer than the rest to arrive in the composition room. While the others hurried upstairs and did not notice Nyo-Nyon, Mitsubashi kidnapped Nyo-Nyon and hid her in a secret room.

Sannou now wants to take Mitsubashi to the Yamanashi Prefectural Police for further interrogation, but Toto and Ron object, saying that she cannot be Hummingbird because she is the real Nyo-Nyon: She betrayed herself with her word choice earlier (referring to "volume" as "level") and showed signs of distress when she was in the composition room with the windows uncovered ("Nyo-Nyon" said "she" was afraid of heights). Mitsubashi admits everything: The other woman is a singer her agency hired to her "face" when she threatened to quick if she had to reveal her own.

Right before Toto uncovered Mitsubashi's secret, Namazu went to the foot of the hill because a suspicious person was sighted there. Sannou decides to head there as well, and Toto, Ron, and Mitsubashi accompany him.

On the drive, Ron tells Sannou "Toto's" deduction: After the smoke alarm went off, "Nyo-Nyon" looked out of the window and saw a group of Yamanashi police officers holding the stretched-out curtain from the storage room. They urged her to jump, she complied, and the officers, being Hummingbird's accomplices, carried her away. Then, one of the false officers had to accuse Mitsubashi of being Hummingbird to drive away with her under the guise of bringing her to the police station—as Sannou tried earlier.

Sannou parks on the side of the road and admits that he is indeed Hummingbird. He kidnaps geniuses for his daughter so that they can talk. Because she is a musical genius, he raised her to be the next top pianist but his strictness and sheltering broke her. The talent of outstanding geniuses is the only thing that still stirs her soul.

Hummingbird then says that "Nyo-Nyon" is in the car's trunk, and while Totomaru and Ron check it, he escapes. To Totomaru's astonishment, Ron confesses that he knew this would happen and did not interfere because he is fascinated by the love he has for his daughter—and because the conversations the abducted geniuses have with Hummingbird's daughter make them happy and help them recover from slumps. He theorizes that the daughter can sympathize with the geniuses' loneliness and heal their wounds with her understanding.

Two months later, Toto and Ron learn that Mitsubashi founded her own agency and created more hit songs. It is unknown whether she met with Hummingbird's daughter in the end; whatever happened, Toto still wants to arrest Hummingbird because he is a criminal nevertheless.

### Psychological Research Lab Murder Case

When Toto visits Ron and sees him playing with dinosaurs, he misinterprets the situation and assumes that Ron has regressed out of boredom and advises him to see Mofu. Ron explains that he is recreating his memories because his recollections before the age of six are spotty, e.g., although he can clearly remember certain events like playing dinosaurs with Max and Molly, he cannot recall the fourth person who was with them. He thought he could remember by reenacting the memory, in vain.

Ron is indeed bored though, and because Toto has no case for him, they contact Chicory. They meet her the next day at Tokyo University as she has to gather data at a psychological research laboratory there.

Together, they head to the Maruyama Laboratory where they are welcomed by Takanori Aoe. He briefly explains what they do—researching the mechanisms of emotions and learning—, and Ron asks if he knows why his early childhood memories are missing pieces. Aoe replies that there are multiple possible causes, e.g. dissociative amnesia. Then, Aoe has to leave, and Kanae Himeno continues the tour.

After Himeno shows Totomaru, Chicory, and Ron the shield room, two members of the lab, Shun Oigawa and Renjiro Imai, get into a fight about using the experiment room in the afternoon. Riko Niki then asks Himeno why she does not "flirt" with Aoe so that he can solve the problem as she "always" does.

Later, when it is time for Totomaru, Ron, and Chicory to leave, Himeno apologizes for the earlier incident. Totomaru says there is no need to worry as everyone can get stressed. His words and Ron's anecdote about the fierce competition at his former school lift Himeno's mood and make her swear to work hard to benefit humanity with her research like Aoe.

The next morning, when Toto and Ron are at Pot Coffee, Toto receives a call from Chicory: Himeno was killed in an explosion at the research lab. Toto and Ron head to the university where Toto approaches Amamiya to ask her to assign the case to him. Though initially against it, Amamiya ultimately gives him the case and leaves. Toto calls Chicory about the development before he and Ron start interviewing the lab members.

First, Totomaru and Ron speak to Aoe. He testifies that he performed an experiment with the MRI machine in the research wing last night. On the way out, he passed by the experiment room, but the light was out. Aoe adds that they lost a computer with ten years' worth of experiment data in the explosion and that they received a threat letter addressed to Himeno this morning; it was sent out yesterday.

Afterward, Toto and Ron interview Imai, Niki, and Oigawa, and they reveal that they all knew that Himeno would use the experiment room this morning: They used a randomizer to determine who would get the slot. Furthermore, not only has none of the students an alibi, but they also all dislike Himeno for various reasons. E.g. Himeno once scolded Niki for cancelling an MRI experiment. Because the MRI machine has a high maintenance cost, they have to keep the operation ratio high and are not permitted to cancel experiments.

Ron then instructs Totomaru to get the experiment room's use log and tells him that he wonders why the threat letter arrived *after* Himeno's death. After all, if its target is dead, a threat letter loses its meaning. Ron adds that it is curious that the culprit sent the letter before it was decided that Himeno would get the experiment room. Totomaru is stunned by Ron's words, stating that it is "unusual" to think that way; it is almost as if he can understand the culprit's thoughts. Ron replies that people have always noted that before he inquires about the use logs. Toto hands them to him, and after Ron reads through them, he solves the case.

They gather the lab team as well as Chicory, who has arrived in the meantime, to reveal what actually happened: Aoe is the culprit. Because he wanted to destroy the computer in the research lab as it contained evidence that he forges the data for his papers, Aoe took the computer to the MRI machine whose magnetism erased the data. To divert attention from the computer, Aoe filled the shield room with flammable gas; the next person that opens the door would then trigger an explosion. He also sent threat letters to each student to the university, and when he found out that Himeno was the one who was killed in the explosion, he picked out her letter and showed it to Toto and Ron.

Ron figured out that Aoe was the culprit because he did not use the experiment room all week, knowing that it would be futile. Aoe admits everything and says that he does not feel bad to have killed Himeno; after all, some sacrifices are required to create a "great man." He then tries to blow everyone up with a bomb, and Ron tackles him before he loses consciousness because of the side effects of his Kill on Sight medication.

The next day, Totomaru attends Himeno's funeral before he visits Ron. Ron wakes up in the evening and tells Toto that he dreamed of his childhood again and that he is sure that there is something important in his past he cannot remember. Totomaru replies that all he remembers from his childhood is looking at his pet hamster's back. Ron remarks that this happens when one is raised looking at a hamster's back—much to Totomaru's confusion.

### Plateau Auberge Serial Murders Case

Toto visits Ron because he called him: Ron received a letter addressed to the manager of the Maison du Kamonohashi which would not be unusual if it had not been postmarked 17 years ago. Back then, Ron's maternal grandfather was the manager, but he has since passed away. Ron only became the manager five years ago when his mother gave him the position. She is currently travelling the world, whereas his father died of an illness before his birth.

Totomaru is unsure whether to accept the dinner invitation; after all, it is uncertain if the auberge is still in business. However, the envelope did not only contain the invitation and menu but also an emerald, and when Ron says they should return it at least, Toto relents. They leave immediately as the dinner is set for today.

On the way, Toto and Ron encounter Tiger Dan and Lenny Gardner who have also been invited to the dinner. Together, they head to the auberge where they are greeted by Shusuke Sakai, the chef and the facility's only employee. He hands out the keys and tells everyone that dinner will be served at 6 p.m. Toto and Ron then meet Mia Costa, another dinner guest, who also has an emerald; hers, however, was given to her by her late mother.

At 6 p.m., everyone enters the dining room and takes place around a round table. Among the guests are also Karen Lily, Bill Clark, and Tom Sasaoka; curiously, a teddy bear sits at the table as well.

One by one, Sakai brings out the four courses: an edible flower salad, lobster soup, fresh fish steamed with white wine and served with a foam garnish, and three kinds of roasted wild game. Dan, Lily, Sasaoka, Gardner, and Clark display discomfort at the sight of every course. Right before dessert, Clark excuses himself, and when Sakai brings out the chestnut mousse cake, the others pass on it as well. Gardner even stands up and says that he should not have come to the auberge after mumbling about wishing that he had not driven his truck on "that day." Because Toto does not speak English, he does not understand his words though.

The next morning, Toto and Ron hear Sakai, Dan, and Lily calling for Gardner in his room: Lily and Dan heard a weird rupturing sound from Gardner's room and wanted to check up on him, but he is unresponsive. Lily picks the lock, and they find Gardner dead in his room with an ice pick lodged in his chest and covered and surrounded by flowers.

Hearing the commotion, the other guests arrive as well. Totomaru reveals that he is a police detective and asks Sakai to contact the local police and Clark to help him examine the corpse. Clark determines that Gardner died about three or four hours ago, and Ron notices that the surface of the ground right below the window is torn up and finds an emerald next to the corpse.

When Sakai returns and says that the landline does not work and that they have no phone reception, everyone goes to check the ropeway station, but it is out of service which means they are now stranded and isolated on the plateau. Sasaoka then runs away, and Toto and Ron hurry after him while the others return to the auberge.

They find Sasaoka in the woods. He explains that, 17 years ago, a man with a crescent moon birthmark invited him to a meal which consisted of the exact same courses as yesterday's dinner. He also hired him to drive a man and a pregnant woman to a hospital; Sasaoka later learned that the man's corpse was found in the Thames. Sasaoka is sure that he was invited to the dinner to be blackmailed because of his involvement in that apparent murder.

Sasaoka's story distresses Ron because his father had a crescent moon birthmark, and just after he tells Toto that, Lily screams because someone taped the menu on the bathroom door. Toto and Ron go into the bathroom and find Sasaoka's corpse inside. He was stabbed in the chest with a knife around 9 a.m. after he struggled against his assailant, and food coloring was used to tint the water red. When Ron takes in the crime scene, he figures out why Sasaoka's and Gardner's bodies were so oddly arranged.

Later, everyone gathers in the dining room, and Toto asks for everyone's whereabouts around 9 a.m. As nobody has an alibi, they are all suspects. Karen protests, saying that they are not even connected together. Ron questions this, and Toto reveals that Gardner's and Sasaoka's murders were modelled after dishes from yesterday's dinner: Gardner was covered in flowers (the edible flower salad), and Sasaoka was placed in red-colored water (the lobster soup). However, while Mia and Sakai do not know the meaning behind the dishes, Sasaoka and Gardner knew it—and so do Clark, Lily, and Dan.

Ron persuades them to confess, and the three admit that they, too, were hired by the man with the crescent moon mark 17 years ago; Gardner and Mia's mother were involved as well. Ron is shocked when he learns that everyone is connected to the Jim Gore Murder Case because the M. Family was behind it. This revelation makes Toto worry for Ron; after all, this would mean his father is connected to the M. Family.

Afterward, Totomaru, Ron, Lily, and Mia decide to look through the locked rooms; Clark and Dan decide to rest instead. When they find nobody, Lily and Mia retreat to their rooms. Ron and Toto, however, keep wandering through the auberge, and Ron admits that he suspects his father to be the crescent moon man because he recalled a childhood memory featuring him.

They then stumble over a storage room where they discover an emerald, a framed picture of Ron's father, and a recorder. The recorder plays a voice recording of Ron receiving a lockpicking lesson from his father—Eliot Moriarty. This unlocks Ron's memories, and he remembers that his father taught him all about crime until he was six. Ron tells Toto about this and voices his frustration and confusion.

A moment later, Sakai arrives to tell Totomaru and Ron that he found Clark's corpse in the wine cellar, covered in extinguishing foam. Because Ron is currently preoccupied with his inner conflict, he cannot investigate, and Toto steps up.

Clark was strangulated, unlike Sasaoka and Gardner, and his body is still warm; and the crime scene is yet another reference to one of yesterday's dishes (fish steamed with white wine and foam garnish). After Toto finishes his examination, he asks what everyone was doing; again, none of the guests has an alibi.

Totomaru then checks the menu, and because "three varieties of roast game" is next on the list, Dan theorizes that three people might die at once next. The guests become nervous about this possibility, and Toto tells them to calm down and wait in the dining room while he and Ron investigate.

Ron is still spaced out when he follows Totomaru through the auberge; he only recovers when Toto says he thought Ron's ancestors were detectives. Ron clarifies that his mother is from the Holmes family while his father is from the M. Family. He also declares that, because he was trained to be a criminal, he has no right to be a detective. The Plateau Auberge Serial Murders Case will, therefore, be his final case, and he will not let himself be talked out of his decision—not even by Toto.

Ron adds that, because the case is strongly connected to the M. Family, one of the invitees may work for them. He and Toto re-examine everything: In the wine cellar, Ron wonders why the culprit risked using the fire extinguisher from the hallway and did not take one of the wines instead, especially considering that newer fire extinguishers contain powder, not foam. And in front of Gardner's door, Ron finds a bloodstain. Ron and Toto then check the flowerbed, as the flowers for Gardner's crime scene were likely taken from the garden. Indeed, some flowers have been plucked, and Ron and Toto keep wondering why the murderer is so fixated on mimicking the food.

A moment later, Lily hurries through the garden because she wants to walk down the mountain. When she is about to walk past a sign saying "Beware of landslides ahead!", Mia and Dan urge her to stop. Toto asks her why she is being so reckless, and Lily says she believes the culprit has a gun because she heard an explosive sound from Gardner's room when he died. Hearing that, Ron solves the case.

Thereafter, everyone assembles in the dining room, and Toto presents Ron's deductions: Gardner was not stabbed inside his room but in front of it. With his last strength, he locked himself in his room and grabbed a flower to hint at his killer. The culprit witnessed that through the window and took flowers from the garden, put them in a balloon, and slipped the balloon under the door. They then inflated it until it exploded, covering Gardner's body in flowers and making the crime scene look like the edible flower salad. Because of that, the murderer had to continue basing the crime scenes on the dishes.

Gardner did not speak Japanese. The flower he grabbed before his death is called "oniyuri" in Japanese—and "tiger lily" in English. Because Lily could have easily picked the lock of Gardner's room, Gardner could have only meant Tiger Dan. Furthermore, the culprit used the fire extinguisher from the hallway because they could not open a wine bottle: They could not get a corkscrew because Sakai was in the kitchen. They also could not break a bottle because it would dirty their clothes; they could not change as they had no more clean clothes: They had to change after fighting Sasaoka in the bath. All this indicates that Dan is the culprit: Sakai had access to a corkscrew after all, Mia brought a lot of clothes, and Lily cannot read Japanese and, thus, could not have known that the fire extinguisher contained foam, not powder.

Dan confesses that he killed so many people to reawaken Ron's Moriarty roots. That Ron could replicate Dan's criminal mind to solve the case shows that he still has a criminal's heart after all. Dan also wanted to use this opportunity to eliminate everyone involved in the Jim Gore Murder Case because the M. Family leaves no trace of its activities.

Ron freezes up when Dan says he is and always will be a Moriarty and criminal, but shakes himself free when Toto tells him to get a grip and that he noticed that Dan is lying although he cannot figure out why. Ron does not understand what Toto means, and Toto points out that it is weird that Dan wants to kill everyone involved in the Jim Gore Case. After all, the M. Family only eliminates those who failed them and that crime 17 years ago was a success.

Dan tells everyone that the case was a failure from the M. Family's perspective because Jim Gore was supposed to be kidnapped, not murdered; they wanted to use him and his research to gain great wealth. For his mistake, Eliot was killed. Dan takes out his gun and points it at Mia and Lily which makes Ron recall his father and regain his resolve. He then confronts Dan: The reason why those involved in the Jim Gore Murder Case were not eliminated 17 years ago is that the M. Family did not know about their involvement until recently, having been outwitted by Eliot. Furthermore, Ron deduces that Gore must still be alive and was likely switched with a dummy corpse in the hospital's garden. After all, his father would always make sure that nobody got hurt and would have never handed over Gore or killed him. Dan confirms everything.

Ron starts to laugh and tells Dan that his plan to convince him to stop doing detective work has failed. Instead, the case made him even more determined to use his intellect to fight the M. Family. Toto orders Dan to drop the gun, but he refuses. Before he can pull the trigger, the teddy bear on Mia's lap starts to move and talk, introducing himself as the M. Family's eldest son Mylo Moriarty. He intended to watch everything silently but decided to reveal himself after Dan's plan failed.

Ron orders Lily, Mia, and Sakai to cover their ears; if they do not hear any more about the M. Family, Mylo could let them go. Although Mylo praises Ron for the idea, he insists on eliminating everyone present. This enrages Totomaru and when he tells Mylo that he should not underestimate the Japanese police, Mylo replies that he is only still alive because he allows it.

Then, Ron's body starts to fail him; he starts to shake and sweat and sinks to his knees. Mylo concludes that this must be a side effect of the medication Ron is taking to counter Kill on Sight: The medication redirects Ron's murderous intent to his innards, and he will eventually succumb to the side effect if he keeps taking it. Furthermore, because Ron resisted Dan's poor attempt to convert him, Mylo gives him a reward: The person who modified his body is an M. Family member—and a spy at BLUE.

Afterward, Mylo sets off the bomb planted in the Auberge Reunion for the main dish: three types of roast game. The building quickly catches fire, and Dan picks up Mylo's teddy bear and escapes. Toto helps Sakai, Lily, and Mia out before he runs back for Ron. However, by that time, the fire has advanced so much, they cannot get out anymore.

Just when they have resigned to their fate, Spitz arrives with a helicopter and saves them. BLUE received a set of coordinates from an anonymous tipster, and Spitz was sent out because he was closest to the location.

With BLUE's help, Mia, Lily, and Sakai go into top-secret protection to ensure the M. Family cannot get to them. And, since the case, Ron complains about his father and says that it is only natural that his "worthless" father got killed. However, because Toto often catches Ron looking at the photo of Eliot he got from the auberge with a smile on his face, he wonders if Ron truly means what he says.

### Fortuneteller Prince Murder Case

Toto and Spitz visit Ron at Pot Coffee while he is working a shift there. Spitz says he was unable to uncover anything about the M. Family spy at BLUE, and Ron decides that he has no other choice but to go to BLUE himself to hunt the mole. After Toto and Spitz remind him that he cannot go there as he was expelled, Ron calms down and takes their orders.

Although Spitz orders a cola and a coffee, Ron gives him a brown sugar drink, having deduced that Spitz only wanted a brown drink. Spitz admits this and then tells Ron and Toto about the Fortuneteller Prince and his Mega-Boost Fortunetelling; he ordered brown drinks because his Mega-Boost items for today included "brown drinks." He also bought three tickets to a signing of the Prince's new book and invites Toto and Ron to come with him.

On the day of the signing, Toto, Spitz, and Ron go to the venue, an inn, and wait for their number to be called. Totomaru is called first and is pleasantly surprised by the Prince, as his kind words made him rather happy. When Totomaru rejoins the others, Ron tells him that the Fortuneteller Prince's correct guess about his good luck was only a trick. However, before Ron can explain what he means, a group of fans discover Lost Koala's corpse in the garden.

Toto contacts Amamiya and inspects the body with the others. The Prince joins them, expressing his sadness over losing a devoted fan and his willingness to help with the investigation.

When the police come, they relay a message from Amamiya (Toto is in charge of the case, and she wishes she could also "play around" at auberges and signings) and conduct Lost Koala's autopsy: She died of strangulation about two hours ago, just before the start of the invite-only party. Witnesses saw Lost Koala arrive early and leave her seat right before the signing. Ron adds that it looks like Lost Koala was strangled with a belt-shaped cord, but such an item was not found anywhere. It might have been flushed down the toilet, and the police will later check the surveillance cameras.

Toto tells an officer to make sure nobody leaves the venue, and after the officer leaves, the Fortuneteller Prince approaches Toto, Ron, and Spitz again. Ron tells him about "Toto's" suspicion from earlier: The Prince knew Toto is a police officer because he quickly searched his name, hiding his phone behind a fan, after Toto gave his name at the signing. Ron also points out the Prince's suspicious certainty that Lost Koala was murdered; the Prince replies that he knows she would have never committed suicide. Toto is quite uneasy about everything Ron is saying on "his" behalf; after all, Ron did not inform him about any of his thoughts beforehand.

After Toto confirms that Ron has taken his medicine, they and Spitz head to the Fortuneteller Prince's room to search for the murder weapon. There, they note that the heater does not work because its remote has no batteries. The Prince then arrives and tells them that he believes in Mega-Boost Fortunetelling "more than anyone" as he was once in a horrible plane crash and thinks he only survived because he had his lucky item with him. He, thus, claims that Lost Koala died because she did not have her lucky charm with her.

Ron continues inspecting the room and finds out that it has access to the courtyard, making it easy for someone to move a corpse to the garden. And if the culprit wore a kimono, they could have easily repaired it, in case it was slightly damaged during the transport. Knowing that Ron and the others are suspecting him, the Prince reminds them that he is friends with politicians: If they have no evidence to prove his guilt, he will tell his friends how he was harassed by the police.

Later, Toto scolds Ron for eating too many sticky buns as his throat will dry out. When he hears that, Ron figures out where the murder weapon is.

While the Fortuneteller Prince is doing a live broadcast from the inn, Toto, Ron, and Spitz search his room, wearing overalls and animal heads to hide their faces from the Prince's audience. When the Prince notices them, they explain that they only wanted to check whether the murder weapon is underneath a cushion or elsewhere. The Fortuneteller Prince allows them to search; meanwhile, his live broadcast continues.

The Prince muses that, if he were the culprit, the murder weapon would be his Mega-Boost ribbon; however, they were all handed over to the forensics team already who analyzed them and found nothing. He then uses this opportunity to advertise his ribbons to his audience before he notes the room's surprisingly high temperature. After all, it is currently very cold in Tokyo. He then reaches for a cup of tea, and Totomaru confronts him about his choice, asking him why he neither chose the coffee (his Mega-Boost item is "brown drinks" after all) nor decided to use the AC to lower the temperature.

The Fortuneteller Prince can make an excuse for why he did not pick the coffee (the heat dulled his judgment) but before he can make another for ignoring the AC, Totomaru exposes his true reasons: The Prince killed Lost Koala with one of the Mega-Boost ribbons. He removed the batteries from the remote, wrapped the ribbon around it, and submerged the batteries in the coffee bottle, effectively hiding the murder weapon. Ron then reveals that they already gave the coffee bottle to forensics: The bottle on the Prince's table is a fake filled with brown sugar.

Defeated, the Prince confesses to murdering Lost Koala; she wanted to defame his Mega-Boost Fortunetelling, and he could not allow that. He asks why it even matters that he was only using a trick as long as his "fortunetelling" made people happy. Toto then informs him that forensics found no conclusive evidence on the ribbon; they, therefore, had to make him admit to his crime during his live broadcast as he could not contradict his own fortunetelling in this situation. They also surrounded the room with heaters to make him thirsty. The Prince is subsequently arrested.

### Severed Head Balloon Case

Totomaru is looking in a mall for Press Butter Sand for his grandmother when he encounters Amamiya. Together, they head to a café where Amamiya complains about Kawasemi's accomplishments since the Mad Chameleon Murder Case—for which she blames Totomaru; after all, he helped Kawasemi out of his slump back then.

Wanting to cheer her up, Toto suggests inviting Ron and texts him, but Ron replies that he is busy right now. Toto and Amamiya then overhear a woman telling her friend about a severed head that floated away with a bundle of balloons; because of the absurdity of the story, she and the other witnesses did not bother going to the police. Whereas Amamiya has her doubts about the story, Toto wants to look into it; when he remarks that this might be a good opportunity to show up Kawasemi, Amamiya begrudgingly agrees to investigate.

Toto and Amamiya go up to the mall's roof with the woman from the café and two other witnesses. They testify that they did a photoshoot here yesterday at 11 p.m. One of them was wearing a clown costume and holding balloons; he eventually noticed blood dripping on his hand and then spotted the severed head among the balloons. Because some blood landed on the costume, it is sent to forensics.

Thereafter, Toto asks for Amamiya's opinion. Because there is nothing on the roof and the closest buildings are dozens of meters away, she theorizes that it might have been an optical illusion: A billboard's image that was reflected by the nearby building's glass facade and onto a balloon. However, this is unlikely as so many witnessed the same illusion; Totomaru correctly guesses this as well.

Toto and Amamiya then question various people in the area. When one of them says he spotted a drone flying above the mall, Toto and Amamiya think this might be the solution; however, the man saw the drone in the evening and it was too small to carry a watermelon. Toto suggests that the head could have been carried by a balloon, but Amamiya informs him that hundreds of balloons would be needed to lift a head.

Later, they return to the mall's roof. Their only lead is a black cloth that was on the roof, and Ron is not replying to Totomaru's texts about the case. Because of how unsuccessful their investigation so far is, Totomaru apologizes to Amamiya for ruining her day off. However, Amamiya says it is fine as this has happened quite often. She adds that she finds the situation rather funny because she never imagined that she would ever investigate a case so eagerly with Toto. Forensics then calls Toto to confirm that the stain on the clown costume is human blood.

This revelation boosts Toto's and Amamiya's spirits, and while they ponder over the case, Ron suddenly arrives, carrying a bag with a Kamonohashi Sweets ice cream delivery. When Amamiya and Toto ask why he is wearing pajamas, he explains that he was in a hurry to bring them the ice cream before it melted.

Excited, Amamiya accepts the ice cream, and while she is distracted, Toto gives Ron a run-down of the case. After Toto shows him a photo of the company building, he receives another call from forensics. They found a match for the blood sample: Omoda, a CEO and the missing person whose case was assigned to Amamiya. She informs Ron and Totomaru that Omoda vanished at his workplace three days ago after receiving an anonymous death threat. He disappeared without a trace although the company's new building is equipped with a state-of-the-art security system.

Amamiya points out the building as it can be seen from the mall's roof. Seeing it, Ron solves the mystery and says that the severed head and the balloon met by accident. However, instead of telling Totomaru his deduction, he leans a half-eaten popsicle against a rise as a hint and tells Toto that he has already met the culprit. Wishing Amamiya and Totomaru good luck, Ron leaves which weirds Totomaru out; after all, Ron always wants to be at the crime scene.

Totomaru then tells Amamiya that he "believes" they have already met the culprit and points out the popsicle to her, saying it may be a hint. When she sees it, Amamiya immediately solves the case. Together, they hurry back to the old condo building to see Takumi Tonami. They questioned him earlier, and now Amamiya unmasks him as the killer:

Tonami killed Omoda in his company's building. Due to its high security, Tonami had to cut Omoda's body into small pieces to get it out. He wrapped the pieces in black clothes and transported them to his condo via a wire he had strung between the two buildings with a drone earlier in the evening; Amamiya saw through this trick after seeing the popsicle piece sliding down the handle. No one but Tonami could have committed the crime because he is the only one who lives directly across from the north side of the company's building, he must be the culprit.

Tonami admits that he killed Omoda because they founded the company together, but Omoda ran him out. After Tonami is arrested, Amamiya thanks Totomaru because they could only solve the case because of him, though she adds that he should not get full of himself as he is still a rookie.

Amamiya then heads home, and Toto goes to the Maison du Kamonohashi and finds Ron waking up from a nap in front of the building. Ron explains that he took his medication a few days ago and, lately, its side effects have not been subsiding after sleeping for a day anymore. Earlier, he had to force himself to go to the mall after receiving Toto's message. On the way back, he fell asleep in front of his apartment building. Toto suggests to stop taking the medication, but Ron refuses. He also tells Toto that they have received their next case: One that is very important to Ron.

### Twin Prison Locked Room Murder Case

Toto asks Ron what he means, and Ron shows him an article by Chicory about the discovery of a seven-year-old corpse in the Okutama Mountains. Shortly afterward, they head to the Moon Prison.

On the way, Ron explains that the prison has a twin building, the Sun Prison in England. 70 years ago, someone was murdered there too, though that locked-room murder has never been solved.

When Toto and Ron arrive at the Moon Prison, they meet Amamiya who allows them to help with the case and briefs them: Seven years ago, Juntaro Mihane bought the prison and locked himself inside it, wanting to reach the goal of the organization he belonged to: connecting with space. Jarr Jorr, the Two Prisons' architect, was part of it too. However, Juntaro was killed not long afterward. His family filed a missing person report back then, but he was never found and eventually declared dead.

Two weeks ago, Juntaro's wife Youko Mihane, his son Kiyotaka, his brother Junji Kaji, and his servant Kaki Sakanoue went to the Moon Prison. Because the prison was locked and only has one unique window they did not want to damage, they had to contact the owner of the Sun Prison. The Moon Prison's key was destroyed in a house fire seven years ago; however, as the two prisons are twin buildings, their keys are identical. The Sun Prison key just arrived, and when Juntaro's family returned to the Moon Prison and unlocked it, they found the corpse. Curiously, they did not see it two weeks earlier looking through the window. Kiyotaka even has photographic proof of that.

Afterward, Amamiya leads Totomaru and Ron inside the Moon Prison to show them that it is a perfect locked-room mystery: If the building is locked, it is impossible to enter or leave it, or for a corpse to disappear or re-appear. An officer remarks that "locked rooms" and "impossible crimes" do not exist outside of fiction and that it might have only been an accident. When Amamiya says that it would be nice to declare it an accident, two hooded people arrive and object: Fin Fennec and her assistant Shachi who want to assume the direction of the crime scene.

While Amamiya briefs Fin, Toto and Ron watch them from afar, and Ron points out that, like Mylo said, a BLUE instructor suddenly appeared before him. Thus, he and Toto need to be careful around Fin as she may be the M. Family spy. Then, Shachi and Fin approach them. Ron suggests to Fin, for old times' sake and to Toto's horror, to compete with Toto to solve the Moon Prison's mystery, but she is uninterested. She informs him that she has heard of the rumor that he is illegally investigating and states that she will punish him without hesitation if the rumor is true.

When Fin is about to return to the prison, she stops and says that she has changed her mind about the competition and accepts it. Because Toto already examined the Moon Prison's interior, it is now her turn. With her Phoenix touch and Shachi's help, Fin thoroughly inspects everything and then declares, to Toto's and Ron's surprise and amazement, that she has solved the mystery.

Fin then gathers everyone to tell them what happened: Neither the culprit nor the corpse entered the prison in the last seven years. Juntaro's corpse was simply hidden behind a dummy wall made of foamed styrol. The blocks were likely connected via a cord that was threaded through the chimney; its end was stuck out of it and fixed to ensure that it did not slip back inside. The culprit never wanted anyone to discover Juntaro, but when they learned that his family was about to open the prison, they pulled on the string, lifting the blocks through the chimney and removing the dummy wall.

Fin deduced that there must have been a dummy wall because, in Kiyotaka's photo, the sunlight is striking a larger area of the wall than it does now. Therefore, two weeks ago, the wall was closer to the window than it was now. Furthermore, the murderer must be someone who knew the Sun Prison key was being delivered to Japan. Having solved the locked room's mystery, Fin and Shachi return to their guesthouse, leaving the Metro Police with the task of finding the culprit.

The next day, Ron tells Toto about the Sun Prison Murder Case, having thought about it all night. Amamiya then calls Toto to inform him that Kaji's corpse was found in the Moon Prison: He was tied to a chair and stabbed to death, just like the Sun Prison victim.

Immediately, Totomaru and Ron head to the Moon Prison; Fin and Shachi returned to investigate as well. Fin says that Kaji was likely stabbed after he was tied to the chair which means that the culprit was with him in the room. However, like in the Sun Prison Murder Case, a brass bar was mounted to the inside of the door, sealing the room from within.

Everyone then helps to thoroughly check the outside of the prison to find proof of whether someone entered or exited the building. In the end, Fin declares the case a perfect locked room right before Kiyotaka, Youko, and Sakanoue arrive.

Kiyotaka testifies that Kaji was fixated on finding Juntaro's killer because Juntaro had not left anything to his younger brother in his will. If Kaji could prove that Kiyotaka was his father's killer, he would get everything. Totomaru notes this must mean that Kaji went to the prison to investigate and then asks Youko for permission to smash the window. She agrees, and Kaji's corpse can finally be examined: He was not drugged, meaning that he was indeed killed inside the prison.

While Toto, Ron, Fin, and Shachi inspect the prison again, Sakanoue yells at them that it is their fault that Kaji died, as they had not arrested the culprit yesterday. Toto wholeheartedly apologizes to her; they only focused on solving the mystery, not apprehending the culprit, and now, another life was lost. His words open Fin's eyes to her own arrogance, and Fin allows Ron to help with the case—as long as he does not solve it because her father used to say that someone is only a detective if they solve the mystery; otherwise, they are only a bystander.

Later, Toto and the others question Youko, Kiyotaka, and Sakanoue. Toto inquires if they know where the brass bar might have been stored, and Kiyotaka reveals that it was kept in a shed at their home. As he, Youko, and Sakanoue all had access to the bar, they are all suspects; this sends Youko into a panic, but Sakanoue is there to tend to her.

Fin and Shachi then travel to the Mihane estate to search the shed for clues, whereas Ron and Totomaru stay behind and talk to Youko who is feeling better again. She tells them that although Sakanoue has become a bit senile, she will not fire her because her late mother hired her and paid her in advance for the next ten years. Youko also admits that she wished they had never opened the Moon Prison. If the others had been on her side, she could have lived in peace.

Hearing this, Ron solves the case. He also realizes that there is a reason why Fin could not figure out the mystery and that the current case is unconnected to the Sun Prison Murder Case; it is only a copycat crime. Ron then asks Sakanoue who has made a cooking mistake lately if Kiyotaka cooks for himself. Sakanoue replies that she has not made a mistake in thirty years.

A moment later, Fin and Shachi return, having found nothing in the shed, and Ron happily announces that he has solved the case.

After Amamiya rejoins them, everyone gathers to listen to Toto's recitation of Ron's deduction: The culprit inserted a neodymium magnet in the brass bar, attached the magnet to the door, and left the room. Thereafter, they used a blowtorch to heat the door and the bar until the bar was heated to 330 degrees—neodymium's Curie temperature, the point that has to be reached for the material to lose its magnetism. The bar then dropped into the brackets and locked the door. Because the magnet's magnetism was destroyed, Fin could not detect it with her Phoenix touch.

Because the culprit used a blowtorch they were not familiar with, they hurt their left hand—and Sakanoue has been suspiciously covering her left hand. Sakanoue killed Juntaro and Kaji to protect Youko. Ron deduced that when he saw how much Sakanoue cares for Youko's well-being; oddly, she does not care for Kiyotaka though.

Sakanoue confesses that she promised Youko's mother to protect her daughter. Youko's mother did not like Juntaro, knowing that he would bring trouble, and she was eventually proven right when Juntaro began squandering the Mihane fortune for his religious group. And then, Kaji tried to pin his brother's murder on Youko and Kiyotaka to get his hands on the fortune. Sakanoue had to kill them to protect Youko and the fortune, and although she has been caught, she is content, as she fulfilled her promise and will die soon anyway.

Later, Fin tells Totomaru that he solved the case well and reveals that she and Shachi actually took an x-ray of the bar and confirmed the magnet's presence inside it before Ron figured out the mystery. She and Shachi then leave, and although Ron wants to talk to them, he cannot as he faints due to his Kill on Sight medication.

A few days later, Toto and Ron head to the airport where Shachi and Fin are waiting for their flight home. Ron tells Fin he solved the Sun Prison Murder Case. She remarks that it is a convincing solution; however, because he has no physical evidence, it cannot be accepted as an official solution.

Fin admits that she knows Ron wants something from her, and he tells her that he is gathering information on the Bloody Field Trip Case and asks why she is interested in that case as well. Fin says she is interested in it for two reasons: First because it is a locked room case. Second because of Aimee's unusual actions. Last year, Fin saw Aimee entering the Bloody Field Trip's crime scene—and Hirsch tailing her. Fin later confronted him about that, and Hirsch claimed he wanted to check if he left anything there. However, Hirsch had nothing to do with the Bloody Field Trip because he was not in England then. Fin stresses that this changes nothing though as the case is already settled before she and Shachi leave for their plane.

Toto and Ron return to the Maison du Kamonohashi. There, Toto asks Ron why he did not inform Fin about the unidentified blood because she might help. Ron replies they cannot rule out that Fin is the M. Family spy and adds that he is thrilled by the current developments as he considers Hirsch a "formidable opponent."

### Missing Cabbage Case

After Toto receives a cryptic text message from Ron, he quickly finishes his work and heads to the Maison du Kamonohashi. On his way, Toto surprisingly encounters Mofu and Chicory together, as he did not know they know each other, but they clarify that they met today for the first time. After they talk a bit, Chicory and Mofu leave to do some "pressing" business.

When Toto arrives at Ron's apartment, he is surprised to see that Amamiya and Kawasemi are there too and asks Ron what is going on. Ron admits that he exaggerated in his message to ensure that Toto would come because it is his birthday today—a fact Toto almost forgot himself. When Chicory and Mofu join them as well, Ron reveals that he invited everyone to throw Toto a hot pot party. Toto is touched by everyone's effort and he thanks them for everything.

Then, Chicory tells everyone that she could not get any Chinese cabbage despite having been to three supermarkets. Toto is fine with not having any cabbage, but Ron and Kawasemi insist that Chinese cabbage is essential to hot pot, and Ron calls Spitz to search a bit farther away.

While they prepare the other vegetables, the television is running in the background; a news broadcast announces that a jewelry store in Tokyo was robbed this morning. Then, Kawasemi and Amamiya get into an argument about the hot pot flavor: He suggests using the *hatchō miso* he brought, but she insists on using the standard soy sauce flavor as they are in Tokyo. Ron ends the quarrel by telling them that the flavor was decided already: The hot pot will be brown sugar-flavored.

A moment later, Spitz arrives; to everyone's shock, he announces that he was in 15 shops and none of them had any Chinese cabbage. Suspicious of the situation and not wanting to forgo cabbage, Ron, Amamiya, Mofu, Chicory, and Kawasemi get ready to investigate this case. Toto and Spitz, however, think they are exaggerating.

After everyone agrees to Ron's plan to solve the mystery of the missing cabbage for Toto's birthday, they realize that they all know him by different names: Amamiya knows him as "Kamoo," Chicory as "Kamokyu," Kawasemi as "Kamosemi," and Mofu as "Kamonohashi." Ron explains that he sometimes does not feel like using his real name; Toto then thinks of a suitable nickname. Toto cannot believe that the others readily accept this "lame" explanation and decide to keep calling Ron by the name they know him.

They then review the facts, and Chicory says that cabbages have not been trending anywhere, but she found out that a greengrocer reported having seen a man in disguise buying all the cabbages. With that in mind, Mofu, Toto, Kawasemi, Amamiya, and Ron each make a guess. However, they are all dismissed.

Mofu thinks the culprit may need so much cabbage because they keep ruining them out of clumsiness (dismissed because no one is as clumsy as Mofu). Totomaru believes a Korean chef he knows may be the culprit as he always covers his face and may need that much cabbage for kimchi (dismissed because no one can make so much kimchi). Kawasemi theorizes that the robber on the news hid the jewels in a cabbage truck and later had to buy out all Chinese cabbages to retrieve the stolen goods (dismissed because the thief was caught and cabbages are cut up before they are displayed). Amamiya suggests that the culprit may be a farmer who wants to "erase" Chinese cabbage from the market to force shoppers to buy something else as a substitute, e.g. lettuce (dismissed because the farmer would not make any profit like that).

Ron says he also thinks the culprit may be a farmer: He may have gotten into a fight with his son who poured pesticides over the cabbages in his anger. The father then delivered the cabbages without knowing any better, and the son had to rush to buy out all the Chinese cabbages so that the reputation of his family business would not be jeopardized because of his anger-fuelled action.

Everyone is satisfied with Ron's theory. However, he insists that he is only an amateur and that Toto will solve the mystery. Stressed because everyone is awaiting his deduction, Toto reaches for a drink in Spitz's shopping bag and discovers multiple receipts which all show that Spitz has purchased dozens of cabbages in various supermarkets. Caught, Spitz confesses that he bought up all cabbages because he despises Chinese cabbage which shocks everyone.

Thereafter, everyone wishes Toto a happy birthday, and Ron brings the nabe hot pot to the table. The pitch-black brown-sugar-syrup-based hot pot garners many unnerved looks. Ron innocently says they agreed on *hatchō miso* in the end and wonders where the brown sugar came from. He suggests searching for the culprit, but Toto replies that they already know who it is. Ron praises him for the quick deduction, and Toto tells him to shut up.

### Invisible Blood Letter Murder Case

Toto watches Amamiya practice *kyūdō* because Ron became interested in checking out her dojo, the Shingen Archery Dojo, and arranged to meet up with him and Amamiya there, though he runs a bit late. Just when Toto wonders where Ron is, he and Amamiya notice him in archery gear. He surprises them with his skills and even receives praise from Mayumi Nakamae, an instructor.

Nakamae invites them to watch her pupils practice, and Ron explains to Toto what they are doing. Eventually, the practice is interrupted by Sabatora Nora who is chasing after a cat, Nekomi, who has run into the Shingen Archery Dojo's shooting range. Nakamae arranges for someone to give the signal—a clap—that everyone should stop shooting, but before Nora can grab Nekomi, she has already jumped over the fence. He runs after her, and the archery students and Nakamae inform Totomaru, Amamiya, and Ron about Nora's infamous incompetence as the district detective.

The next day, Toto and Ron return to the dojo after Shu Kotegawa's corpse is discovered there. He died of asphyxia sometime between 10 p.m. and midnight after someone shot an arrow into his vertebrae; Akane Saien found his corpse this morning when she came to clean. Additionally, the culprit seems to have only taken Kotegawa's smartphone, and when Ron examines the body, he notices blood on Kotegawa's index finger. He seems to have left behind a dying message, but nothing is written on the ground.

Nora joins them at the crime scene, and when Totomaru inquires how he got in, Nora shows him and Ron his C-rank detective license. He explains that he received it through self-study which strengthens Ron's suspicion that Nora's license may be a forgery; after all, Nora does not seem to be a skilled detective at all. Thereafter, Amamiya arrives and tells Toto that it is time to interrogate the dojo's members.

Neither Saien, Nakamae, nor Mikio Toban have an alibi for the time of Kotegawa's death, and all of them testify that they have never seen the arrow with which Kotegawa was killed. However, Toban says that he cannot be the culprit, as they are evidently a skilled archer and he is currently in a slump. He was also running around in the area last night, and when he passed by the dojo, he heard someone practicing there; he did not take a look but knows from the sound of the bow that it was nobody he knew.

Nakamae, Toban, and Saien then speak about the upcoming tournament where Kotegawa was meant to be the *ochi*. There are names for the positions where the archers stand and when they fire: *Oomae*, *niteki*, *naka*, *yonteki*, and *ochi*. Suddenly, Nora declares that somebody is lying but cannot elaborate. For that, Amamiya drags him away for the "nonsense" interruption, and Toto tells Toban, Saien, and Nakamae not to pay any attention to Nora's "crazy statement." Ron, however, agrees with Nora, having solved the case just now.

After Nora returns from having received a lesson from Amamiya and makes an outrageous deduction, Totomaru steps forward and reveals that he knows what occurred: Kotegawa did not write a dying message, but the blood on his index finger hints to his killer as it points out an archery position, *niteki*. There is nobody at the dojo associated with that position; however, the name can also be read as *nakamae* (before *naka*) which means that Nakamae is the culprit.

Immediately, Nakamae admits her guilt and says that she killed Kotegawa because he said something that "dirtied" the honor of the Shingen School. Although Ron figured out the meaning of Kotegawa's blood message, he was unsure of Nakamae's motive, but when Nora remarks that she is lying, Ron understands what happened: Nakamae did not murder Kotegawa; it was an accident. She was practicing with him because she is in a slump and used a weaker bow to correct her form; for that reason, Toban did not recognize its sound. Nakamae accidentally shot Kotegawa when he was in the shooting range because she had not heard his clap as he was standing to her left, and she is deaf in her left ear.

Nakamae confesses that Ron is correct. She asked Kotegawa to help her, and when she killed him by accident, she removed all traces of their practice. She even put the blood on Kotegawa's finger to make the accident look like murder, as she wanted to be a "peerless archer" to the end instead of a "worn-out archery instructor."

Afterward, Toto and Ron speak to Nora about his talent for detecting lies. Toto, on Ron's behalf, asks him if his skill has anything to do with crows, and Nora replies that he hates crows since he was attacked by one as a child. Ron realizes that Nora's fear of crows must amplify his lie-detection skill. This excites Ron because he could use Nora in the future; his "demonic" excitement rather horrifies Toto.

### Coin and Carving Murders Case

At the Tokyo Seaside Medical University, Toto observes Nagaoka's autopsy of the third victim in the Coin and Carving Murders Case. Afterward, he visits Ron who is terribly bored and jealous because he read that Fin recently solved an ancient pyramid's looked room. Hearing about his frustration, Toto tells Ron about his current case: A serial murderer has been leaving foreign coins in their victims' bodies and carving numbers into their abdomen. Further, the victims' only commonality is the fact that they are in their thirties or older.

Just when Toto finishes telling Ron about the case, Amamiya calls him. She wants him to meet a visitor in her stead, Hirsch; he was invited to Japan by the Metropolitan Police Department and the Seaside University to lecture them about his techniques for solving cases through autopsies. The timing makes Totomaru and Ron suspicious: After all, Mylo said they would meet the BLUE spy soon, and Fin stated that Hirsch was behaving oddly around the crime scene of the Bloody Field Trip Case.

Totomaru and Ron meet Hirsch at the Seaside University. Ron tells Toto that Hirsch was a murder suspect 15 times but was never proven guilty due to a "nice and tidy" lack of evidence; Hirsch also once tried to kill Ron when he was still a student at BLUE, though Hirsch insists this was a mere "prank." Toto then receives a call that another body with a carved number was found. When Hirsch hears that, he gets permission to investigate the case as well and "employs" Ron as his assistant.

Toto, Ron, and Hirsch head to the river terrace where Ryu Yanobe's body was discovered. Ron examines the corpse; everything is the same as with the previous victims, and Yanobe seems to have been killed elsewhere and then brought to the river later. Hirsch agrees with him and states that he wants to perform Yanobe's autopsy, giving Toto the task of obtaining an analysis permit for him. Ron also pushes his research task regarding the victims to Toto which frustrates him. Afterward, they head to the Metro Police's headquarters.

While Totomaru talks to Yanobe's wife and does his other assignments, Ron and Hirsch wait in a conference room. When he is finally done with everything, he joins them and announces that Yanobe's autopsy is scheduled for today. However, he did not get the permit for Hirsch as a surgeon is already assigned to the case. Hirsch then runs out in anger.

Later, when Toto and Ron are at a restaurant, Toto learns that a corpse was found at the Seaside University. They immediately go there, and although Toto could not reach Hirsch, he still arrives. Because there are now two corpses that need to be autopsied, Hirsch insists to help and even pulls out his detective license to speed up the formal procedures. Ron asks how Hirsch could know about the fifth body, and Hirsch replies that he was simply passing by.

The next day, Toto, Ron, and Hirsch meet up with Nagaoka for the double autopsy. Nagaoka's proposal to take turns examining the corpses is overturned by Hirsch's persistence to perform both autopsies at once; however, Toto and Ron will watch over the autopsies.

Ron and Nagaoka handle the fifth victim, whereas Totomaru and Hirsch examine Yanobe. During the autopsies, Hirsch says that the serial killer might have killed before and asks whether there was an unsolved murder before the Coin and Carving Murders began. Totomaru replies that a doctor was stabbed in Tokyo a while ago. Oddly, there is no coin inside the fifth victim, but one was placed inside Yanobe. Toto also notices Hirsch taking something out of Yanobe's body and hiding it, but Hirsch denies it when Ron and Toto later confront him. And while Toto and Ron ponder why Hirsch might have taken that item, Ron solves the case.

At night, Totomaru and Ron wait for Hirsch to arrive in the morgue. When he does, Toto states that the fifth victim was not murdered; he died of a congenital heart disease, and Hirsch carved the number into his abdomen to make him look like one of the serial killer's victims. Therefore, Toto thinks Hirsch must be the culprit, but Ron and Hirsch tell him that he is wrong: Hirsch is not the murderer; they will come soon though. And indeed, a moment later, Nagaoka enters the morgue.

Ron and Hirsch then present their deductions: The culprit carved numbers into their victims and hid coins within them because they wanted to retrieve the corpses. After all, the numbers would hint at a serial killing, and the coins would make autopsies a must. The culprit could, thus, be no one else than the case's forensic scientist, Nagaoka. Furthermore, the numbers were carved into the victims' lower abdomen to conceal their appendicitis scars. The doctor that was murdered a while ago was the gastrointestinal surgeon who performed the victims' surgeries and he had hidden something within his patients' bodies that Nagaoka wanted to retrieve.

Nagaoka confesses that he killed the doctor after he learned that he stole the diamond that was made of his wife's ashes. Afterward, Nagaoka went on to find and kill the doctor's patients to locate the diamond; the coins are keepsakes from the trips Nagaoka took with his wife. Hirsch then reveals that he did not find the diamond inside Yanobe; he tricked Nagaoka into admitting his crimes. Because of his Kill on Sight medication, Ron subsequently faints.

A few days later, Toto and Ron meet up with Hirsch again at the Seaside University. Ron tells Hirsch he was certain that his "odd" actions were to catch the serial murderer when he insisted on the dual autopsy. When Toto asks Hirsch how he prepared the faux victim, Hirsch says he asked the dead man's family for permission. He then offers to give Ron more information on the Bloody Field Trip Case: He had been fishing in the mountains for his vacation when Scotland Yard asked him to perform the autopsies. Intrigued, Hirsch agreed, but although the victims were skillfully killed, there was nothing remarkable about the corpses.

Hirsch thinks that the Bloody Field Trip Case is only noteworthy because someone erased the data of a blood sample found at the crime scene and spread the rumor that Hirsch was overseas when the crime happened. When Ron tells him that the M. Family might have been involved in the case, Hirsch backtracks and says he and anyone else should ignore the case, as he thinks no one should pry into the M. Family's matters. He adds that whoever told Toto and Ron about the rumor that he was out of state back then is likely an M. Family member before he leaves.

Sometime later, Toto and Ron discuss Hirsch's words and Ron's time at BLUE. Just after Ron states that he did not have any friends at that time, someone knocks on the door and collapses onto the floor when Ron opens it. The man calls Ron "cold" as they used to be friends at BLUE right before he passes out.

### Obon Dance Murder Case

Subsequently, Toto and Ron take the man to a hospital. He was, apparently, in a hit-and-run but because he is only mildly injured and does not want to file a police report, Ron suspects that he is lying; he also cannot remember him at all from his BLUE days. The man then joins them and introduces himself as Elmer Stingray. He claims that although he had transferred to BLUE only three days before the Bloody Field Trip Case, he and Ron became good friends, and Ron even accepted Elmer as his investigative partner. Further, Elmer spent the last five years tracking down Ron because he vanished after his expulsion.

Still suspicious, Ron decides to keep Elmer close for now so that he and Toto can gauge him properly. They show him around and eventually find an Obon festival and agree to attend it. There, they run into Chicory who is gathering material on summer festivals. Because Chicory calls Toto "Officer Isshiki," Hiiragi, the manager of the famous singer Nana Haruno, approaches him and asks for a favor: 15 years ago, when Haruno performed at this festival as well, she received a death threat. Though she has received no such note this time, the culprit has likely been released from prison by now, and Hiiragi fears that they might still return for revenge. Toto, Ron, and the others agree to help and watch the venue.

During Haruno's performance, Totomaru wants to "win" against Elmer and establish himself as Ron's investigative partner. However, he embarrassingly mistakes fireworks and a laser light gun for a gunshot and a real weapon. A moment later, all lights go out and a scream rings through the loudspeakers. Totomaru, Ron, and Elmer hurry to the stage and discover that Haruno was stabbed.

Haruno, in critical condition, is rushed to a hospital, and Hiiragi accompanies her, whereas Toto and the others stay behind and investigate the case. The murder weapon was stolen from a takoyaki booth, and a man from the neighborhood association turned off the lights for 30 seconds at 6:15 p.m. because he received a message from Hiiragi. However, they find her phone in the trash, and Hiiragi testifies that she lost her phone before Haruno's performance.

Afterward, Toto and the others speak to the musicians that were on stage with Haruno. Each of them—Tsutsui, Kimura, and Tateishi—plays an instrument that requires both hands. Thus, none of them could have stabbed Haruno without stopping to play, and the music continued throughout the attempted murder. They also did not notice anyone coming on stage during the blackout.

Toto, Ron, Elmer, and Chicory then discuss the case. Elmer believes the culprit from 15 years ago might be one of the musicians, pretending to be a local. Chicory mentions that person also used to gift poisoned chocolate to other idols, and while she checks the previous case again, Toto calls Hiiragi for further information: Back then, a box cutter blade and a bullet were sent to the office of Haruno's agency back then. The bullet also reminds Hiiragi of the earlier commotion. Chicory returns and announces that the old culprit is already dead.

Determined to identify the new culprit, Totomaru attempts to play the musicians' instruments one-handedly and, by chance, discovers that one of Haruno's false nails is lodged deep inside the stage's paving stones. Ron then solves the case. Right afterward, Toto receives a call from Haruno's hospital that she regained consciousness, and Ron instructs the hospital to get Haruno a bodyguard as the culprit will try to finish their business.

Toto and the others hurry to the hospital and can stop Hiiragi just in time. She was hiding under the stage during Haruno's performance. The blackout was meant for a costume change, but when the lights went out, Hiiragi stabbed Haruno instead. Hiiragi gave herself away when she mentioned the gun commotion: If she had been in front of the stage as she claimed, she would have known that Totomaru had made a mistake and there had never been a gun. Furthermore, Hiiragi asked for Toto's help protecting Haruno because she had not planned to kill Haruno. However, when Haruno mentioned that she had given away the candy she received back then to children, Hiiragi decided to murder her.

Hiiragi admits that she wants to kill Haruno because she was one of the children who got candy. She gave hers to her bedridden mother; she died not long afterward, and Hiiragi believes that the candy must have been poisoned. Haruno woke up in the meantime and now reveals that she did not give Hiiragi the candy that a fan gave her: When Hiiragi came to Haruno, she had already run out of candy and given her other sweets as a substitute. Shocked, Hiiragi apologizes to Haruno.

Thereafter, Totomaru, Ron, and Elmer head home, and Elmer says he will stay in Japan for a while before they part ways.

### Invitation From Mylo and Bloody Field Trip Case

Days later, Toto visits Ron, wanting to discuss again the possibility that Elmer might be the M. Family informant as he thinks he is highly suspicious, when a courier arrives with a letter from Mylo and an invitation to a cruise. Mylo writes that the people connected to BLUE Ron has met lately will be on that ship as well; one of them is the M. Family informant, and Ron will have to identify them during the cruise. However, if Ron declines the invitation, he will never learn the truth about the Bloody Field Trip Case.

Toto points out the cruise is a trap; still, Ron insists to go, as he does not want to lose his only chance to clear his name and rid himself of Kill on Sight. He will not go unprepared though and requests Spitz to speak to Aimee and find out if she discovered anything new.

Later that day, Toto and Ron head to Pot Coffee. There, they not only get a call from Spitz telling them that Aimee has no new information but also notice Winter observing them. They rush out, and while Toto and Ron cannot catch Winter, they see that they have left them the original file about the Bloody Field Trip Case. Thereafter, they and Spitz regroup at Ron's apartment to discuss the file. Toto wonders whether it is genuine, and Ron replies that it most likely is as Winter plays fair. Having read the file, Ron tells Toto and Spitz what happened five years ago:

Elmer did transfer to BLUE three days before the Bloody Field Trip though Ron did not register him, and Hirsch was indeed on holiday when the incident occurred. By the time Elmer transferred, Ron had been chosen for the joint investigation with Scotland Yard and already located the murderers' hideout. Ron then received a locked room mystery from Fin, and after he got a pack of brown sugar syrup from Shachi, Ron spent the next three days in an underground room pondering about his homework; he even fell asleep from exhaustion at some point.

Ron handed in his homework and immediately headed to the hideout, an abandoned factory. He arrived at 4 p.m. and although he initially wanted to wait for the police to come, a child's cry drew him inside the hideout. This was a trap though, and the criminals were waiting for Ron. While he fought them, he blacked out and woke up when he heard Big Ben chime at 5 p.m. Scotland Yard then found him surrounded by corpses and holding the murder weapon.

Fin was put in charge of the investigation because the incident was a locked room mystery. She determined that only Ron could have entered or left the factory during the time of the crime. Hirsch autopsied the bodies and stated that all criminals died when Ron was unconscious; the bodies also had not been moved. Their evaluations led to Ron's conviction. Additionally, the mysterious third party's blood was found on Ron's vest.

Considering all that, Ron has four theories: Fin might have lied that it was a locked-room scenario. Hirsch might have falsified the estimated time of death; he could have killed the murderers elsewhere and later brought them to the factory. Shachi might have mixed some hallucinogen into the brown sugar he gave Ron; the drug made Ron do things while he was unconscious. Lastly, Elmer disguised himself as a police officer to get access to the case file; he could have, thus, tampered with it and made it worse.

With the new information and his theories, Ron now feels ready to go on the cruise and find the informant.

### Tragic Cruise Serial Murders Case

When Toto arrives in Ron's apartment, no one is there which puzzles him. Only a moment later, Ron appears though, having given his cat into someone else's care. With all matters settled, Toto and Ron head to Yokohama to board the *Precious Dolphin*. There, an attendant familiarizes them with the ship's layout and offerings before she hands them the key card to their room, number 306, and mentions the welcome party that will be held in the Precious Hall later.

At the party, Totomaru and Ron encounter Spitz who sneaked on the ship disguised as a waiter, though he is quickly identified as a stowaway and escorted off the ship. They also run into Elmer, Fin, Shachi, and Hirsch. Elmer claims to be on the cruise because he had a "hunch" that Ron would be on it, whereas Fin states her father invited her.

Later, when the *Precious Dolphin* departs, Toto and Ron receive an itinerary of the ship's course, along with a message from Mylo: At midnight in Bar Mermaid, someone will give them a clue about the M. Family spy. Toto and Ron, thus, head to the bar and survey the area; Hirsch is there as well. When it turns midnight, someone starts playing the piano, and a man dies after drinking poisoned wine.

Hirsch calms down the bar's patrons to avoid mass panic and introduces himself as a forensic detective, Ron as his assistant, and Totomaru as a police officer to a waiter. The waiter tells them that it is the man's 40th birthday. For the occasion, his wife Rumi requested a song and a wine made in his birth year, and the bottle was already on the counter when the bar opened. However, the voice on the telephone sounded mechanical and male, meaning that someone else made that call. Ron examines the bottle and finds out that someone placed a false label over the correct one to conceal the fact that the wine was not made in the man's birth year.

Thereafter, Ron and Totomaru return to their room and find the satellite phone Ron brought destroyed. Mylo calls them a moment later via the ship's phone to tell them that the informant killed the man and that they will murder a person every day until Ron has found them. The only way to stop the informant though is to kill them; for that, Mylo has provided Ron with a gun. Angered, Ron proposes a safety measure to Totomaru. After they went through with it, Toto talks to the captain, Todoroki. He tells Toto that there is a network failure and he also cannot use his satellite phone. Further, the *Precious Dolphin* will not return to Japan because of a typhoon, and the cruise will continue for now.

Toto later joins Ron in Bar Mermaid. Ron is wondering why the bottle's label was pasted over and not a bottle from the correct year was used. When Toto says that the M. Family can get wine from any year, Ron realizes that the culprit must have prepared one poisoned bottle of wine and multiple false labels. Upon learning the victim's birthday, they simply placed the corresponding false label on the bottle. It was, therefore, an indiscriminate murder, and the crime was only committed to give Ron a clue.

The next day, Toto and Ron find Fin and Shachi in the Whale Café. Ron asks Fin to tell him why she determined the Bloody Field Trip Case a locked room mystery; she tells him everything that was in the case file and adds that Ron behaved oddly on that day. When Ron asks Shachi why he brought so much brown sugar syrup, Shachi replies that he was making a lot of Japanese sweets back then. Before Ron can inquire further, someone screams for help, and when they rush outside, a woman crashes head-first onto the ground; she is tangled in ropes.

Fin examines the woman and says that she will die as her cervical vertebrae are broken. Because she was dropped from the deck above, Toto and the others hurry upstairs and find rubber plugs by the door and a woman with ropes to her feet. Ron and Fin quickly realize what happened, and Fin explains it to the others: The culprit drugged the two women, college friends, and tied them up together; one was tied to the railing, whereas the other was dangled over the edge. When the woman on the deck regained consciousness, she used the knife that lay at her feet to cut herself free. As soon as the rope was cut, the other woman fell. The plugs were placed with the help of the ship's swaying and used to keep the door shut.

Afterward, Toto, Ron, Fin, and Shachi talk to Todoroki and return to their respective rooms. Ron points out that the informant is targeting pairs and forcing one to unknowingly kill the other, likely to make the situation more tragic and entice Ron to use the gun. Wanting to protect Ron, Toto wracks his brain and comes up with a way to identify the spy: They refill the bottle used in the first murder with normal wine and offer it to the suspects (except Hirsch who witnessed the murder) to gauge their reactions. The culprit, knowing about the poison, might hesitate to take the offer.

Toto and Ron first extend the wine to Elmer who accepts the offer. However, he realizes that it is not a Flajolet before he drinks it. Elmer also says he has been rather seasick and quickly excuses himself and retreats to his room. Ron and Toto then run into Shachi and Fin; Shachi happily guzzles down multiple glasses, but Fin refuses the wine. While Totomaru does not know what to make of their reactions, Ron is satisfied with the results of the test.

Done with the wine, Fin tells Totomaru and Ron that she found an A-rank detective license at the crime scene of the second murder. It is most likely Hirsch's, and Hirsch apparently also called away the receptionist during the time of the first murder. A phone line runs from the bar to the reception, and Hirsch might have used the phone to order the anniversary wine. Just then, Hirsch joins them, and when Fin shows him the detective license, he confirms it as his. He noticed that it was gone in the afternoon. Shachi found it under the railing around noon, and when Fin examined the license, she determined that it had been on deck for less than an hour. Therefore, it is possible that the murderer retroactively left the license at the crime scene to throw off the investigation. Further, Hirsch states that the receptionist was gone back then because they were looking at his defective card key.

Fin says that she is suspecting everyone right now to be safe, though she cannot think of a motive. She wants to catch the culprit before they murder again, and when Ron asks why she is certain that there will be another murder, Shachi chimes in. Because the culprit has not been caught yet, it is only logical that they would continue.

On the way to their room, Totomaru says he wanted to tell the others that the M. Family informant is behind the killings. Ron agrees; it will be risky, but by informing the others, they might make it harder for the spy to continue. They proceed to admit everything to Fin, Shachi, Elmer, and Hirsch. They all agree to help. Elmer also says that Ron helped him when he got hurt at BLUE, and he now has to repay his "debt." Everyone then gathers in Fin's room to search for the spy together.

On Elmer's suggestion, they head to the lobby on the sixth floor. Ron's plan is that they simply all stay together; after all, if they are gathered, the informant cannot make a move without exposing themselves. Hirsch reveals that one victim from the Bloody Field Trip Case was not stabbed in the heart like the others, and Fin questions whether Hirsch truly performed the autopsies back then before the conversation dies down.

At some point, Toto ponders aloud about the case, and after Fin hears him, he strikes up a conversation with her. He inquires about her and Shachi's partnership, and Fin explains that Shachi's family has served hers for generations. They have known each other since childhood, and Shachi saved her multiple times.

Hirsch then finds a crumpled piece of paper. On it, the culprit has written "⬤ol 00:10 Third victim." Everyone comes together and determines that this must mean that another murder will happen ten minutes after midnight in a room whose number ends in "01." Because they only have 15 minutes to check six potential rooms, they split up: Toto goes to 101, Fin to 201, Shachi to 301, Hirsch to 401, Elmer to 501, and Ron to 601. They also agree to meet up again in the lobby at 12:20, regardless of what happens, before hurry to their respective rooms.

Totomaru checks his assigned room; the guests inside are suspicious of him, but seem fine. Afterward, on the way back to the sixth-floor lobby, Totomaru runs into Ron. Ron admits that he never thought the code referred to a room number and that it was simply a scheme to separate everyone. He thought he could figure out the true meaning within ten minutes but could not; he then went to Toto to get a hint. Toto has no idea how he can help and only says he wonders why the passenger rooms are only on six floors when the ship has seven floors. His words make Ron realize that not a number was obscured but the word "pool."

Immediately, they head to the pool on the seventh floor. There, they find two people bound together back to back with tape, flipping themselves over, and fighting against drowning—and spot the culprit running away. While Totomaru jumps into the pool, Ron hastes after the informant.

Toto manages to pull the victims out on time. Ron rejoins him at the pool and informs him that the spy got away, but left behind a satellite phone. The others arrive shortly afterward because they noticed that the elevator stopped on the seventh floor. After Ron explains everything to them, Fin, Shachi, Elmer, and Hirsch state that there was nothing amiss in the rooms they checked. The people in room 201 were suspicious but cooperative, the guests in 301 scolded Shachi, and the ones in 501 offered Elmer tea.

Ron asks them to stay by the pool while he goes to check the final piece that proves who the informant is. Toto follows Ron to a quiet part by the stairs, and Ron calls Spitz to find out the results of a DNA test. When Spitz was briefly on the ship, he offered each suspect a glass; they all accepted and then returned the glasses to him. Spitz could take the glasses with him and then compared the DNA on the glasses with the DNA of the third-party blood on Ron's vest: It is Elmer's. Having now thoroughly confirmed his suspicions, Ron solves the case which relieves Toto.

Totomaru starts praying that they will be able to catch the culprit and return Ron's body to normal. This reminds Ron of their first encounter, and he thanks Toto for always believing in him. A moment later, smoke spreads and someone knocks Toto and Ron unconscious with a metal pipe.

Toto is tied up on a chair outside the Precious Hall. Inside it, Ron faces Mylo's robot teddy and identifies Shachi as the informant. He figured out it must be him, i.a., because everything the culprit did turned suspicions away from Fin: The trick with the plugs relied too much on chance and the voice changer made everyone suspect a man, not a woman. Furthermore, Shachi drank so much of the wine to double-check it for poison. And when Shachi said the people in room 301 scolded him, Ron knew for certain that he was the informant: He and Totomaru had secretly changed rooms and were now staying in 301.

Ron also solved the Bloody Field Trip Case: Shachi drugged him and then changed the date on his phone. When Ron woke up, he believed three days had passed, not two, and headed to the factory where he lost consciousness. An imposter filled in Ron's place on the actual day of the exercise and treated Elmer when he got injured; some of Elmer's blood landed on his vest. The imposter then went to the hideout, killed the criminals, and dressed Ron in his bloodstained uniform before he stabbed himself and handed Ron the knife with his last strength.

Shachi confesses to his crimes and takes out a gun. He forces the audience to stay seated and reveals that the doors are locked and cannot be forcibly opened without killing everyone in the Precious Hall. In ten minutes, a device will release nerve gas; only if Ron shoots the lock of the only door without a motion sensor, everyone will be able to escape. This door is the one Toto sits in front of, wearing noise-cancelling headphones: Ron cannot alert him and he can only save the passengers if he kills his partner.

After Elmer makes Shachi shoot a hole in the door, Ron picks up a stool from the stage. He raises it upside down over his head but does not throw it. After his attempt to appeal to Shachi by telling him that he is disappointing Fin fails, Ron sets the stool down and shoots the door's lock.

Mylo is satisfied because Ron has now proven that he is truly a Moriarty and betrayed someone who trusted him. To everyone's surprise, Toto is not dead though: Ron used the principle behind pinhole cameras, and when he lifted the stool, he held it in a way that projected it through the hole to the wall on the other side of the door. The image of the stool reminded Toto of a shrine and his and Ron's first encounter when Ron deduced that Toto walked alongside the trees by the Wakana Shrine. Toto understood the message and leaned to the side. When Ron shot the lock, the bullet only grazed Toto and did not pierce his heart.

Ron taunts Mylo, telling him that he can "move forward without killing anyone." While they stare at each other and do not pay attention to anything else, Shachi grabs Fin and runs out of the hall. The passengers follow suit. Toto and Ron pursue Shachi, and Elmer stays behind and brings the still-unconscious Hirsch to safety.

Totomaru and Ron chase Shachi to the deck where Mylo already waits for them. He shoots Shachi in the shoulder and announces that the ship is now under his control. Shachi swears to Mylo that he will not fail him again, and Ron points out that Shachi did everything right but Ron still managed to solve everything. He has also deduced that Shachi is only working for Mylo because the M. Family took Fin hostage multiple times in the past. Fin then wakes up, and Shachi admits everything to her. However, before he can reveal what was done to Ron's brain, Mylo shoots Shachi in the heart.

Because Ron last took his medication too long ago and its effect has already worn off, Mylo's action triggers Kill on Sight. Ron tries to persuade Mylo to shoot himself in the temple, but Mylo shoots Toto instead. As Kill on Sight is a kind of "hypnosis," you can shield yourself by filtering Ron's voice with a sound alteration device, and Mylo wears such a device in his ears.

Mylo sends his bodyguards away and throws a knife to Ron. He did not kill Toto as he still wants Ron to do it; as a "reward," Mylo will give Ron a flash drive containing all the information on what was done to his body five years ago. However, the fact that Mylo injured Toto angers Ron so terribly that the voice alteration does not work against Kill on Sight anymore. Ron compels Mylo to throw his gun into the ocean, and Mylo cannot resist and complies. He then hands him the knife and orders him to stab himself but Toto can get through to Ron and stop him by reminding him that he would never kill anyone.

Ron breaks free of his trance. However, Mylo is willing to die if he can make Ron break the "detective's taboo" of never killing anyone and keeps taunting him. He even produces a second gun from his sleeve and shoots Fin. Despite Toto's best efforts to keep him grounded, Ron struggles to suppress Kill on Sight and can only think of one way to stop himself: To everyone's shock, Ron stabs his vocal cords and collapses. Then, Elmer and Hirsch arrive, and Mylo admits defeat. He throws the flash drive to Totomaru before he throws himself into the ocean.

Thereafter, Hirsch gives first aid to everyone still alive, the *Precious Dolphin* docks at the closest port, Naha, and the injured are rushed to a hospital.

The night Toto wakes up, Winter visits him to thank him for taking down Mylo. In return, Toto asks them why Mylo was fixated on making Ron kill him and forcing people to kill their loved ones. He thinks Mylo might have experienced something similar. Winter can only think of Mylo killing their little sister Alice, though they doubt that is the reason behind his actions; after all, Mylo disliked Alice, as far as Winter knows.

After Toto is discharged, he meets with Elmer in Pot Coffee. Toto, being still suspicious of him, asks him who he is. Elmer simply hands him an explanatory letter to give to Ron before he returns to America.

Two months later, Toto reflects on the events, writing everything down in Pot Coffee, when he gets the call that Ron has been discharged. Immediately, Toto heads to the hospital. Amamiya has come to see him too, though she is quickly called back to work.

Toto and Ron return to the Maison du Kamonohashi. There, Toto gives Ron Elmer's letter, though it is not from him—it is from Romi Holmes, Ron's mother. She writes that Elmer has been working for the Holmes family since he was young, and she sent Elmer to Japan when he heard that Ron was targeted and wanted to help. Romi closes her letter expressing her hope that she and Ron will meet again before one of their funerals.

Mofu then arrives to announce that she finished analyzing the data on Mylo's flash drive. She could determine the cause of Kill on Sight and is confident that she can fix Ron's brain. Spitz also comes and informs Ron that he explained everything to BLUE, and the World Detective Alliance overturned Ron's punishment, meaning he can now take his test to get a detective license. All the good news overjoys Ron, and he collapses to the Floor of Sloth in absolute happiness. Toto is delighted for his friend.

### Ron Kamonohashi's Homecoming Case

Sometime later, when Ron can speak again, Toto accompanies him to BLUE to get his diploma. Amamiya bids them goodbye at the airport; and because of what transpired the last time Totomaru and Ron travelled, Amamiya gifts them good luck charms. Chicory, Mofu, and Kawasemi did as well. After Amamiya leaves, Spitz Feier joins Toto and Ron, and together they leave for England.

On the way to BLUE, Toto impresses Ron with his English skills by conversing fluently with the taxi driver. He explains that he asked Spitz and Kawasemi to teach him after the Plateau Auberge Serial Murders Case; Kawasemi in particular took those lessons very seriously, waking Toto up as early as 3 a.m.

At BLUE, they meet Aimee in her office. She gives Ron his graduation certificate and congratulates him before she asks if he could substitute for an instructor who went missing. Ron declines and, to Totomaru's horror, suggests that Totomaru takes his place instead; he himself will be Totomaru's assistant. Toto and Aimee, albeit reluctantly, accept.

Toto's first lecture does not go well; not only do most students ignore him, but also a monkey jumps on him. Afterward, Ron and Spitz tell him that this is normal for new instructors at BLUE. While Spitz goes to prepare for his next class, Ron shows Toto around the academy. They run into Hirsch but he quickly leaves, not wanting to be anywhere near them.

When Ron is about to bring Totomaru to the place with the best view in BLUE, they encounter two of Totomaru's students, Marsh Leipley and Udy Dietner. They wanted to prepare for their next class, but the door is locked. Because Ron lacks the special tools needed to pick the lock, Toto climbs on Ron's shoulders to look through the window above the door and spot Alissa Beaumont's lifeless body in the room.

As the key is in the staff room and, thus, too far away, Toto and Ron decide to enter the room via the ledge outside. However, the room's window is locked as well, and someone also threw Alissa's head into the pond below. To Toto's surprise, Ron immediately deduces what happened and he sends Udy and Marsh away to get the key so that he can tell Toto everything.

Marsh and Udy do not only return with the key but also with many other students who want to see Totomaru solve an apparent murder case. Toto tells the gathered mass that Alissa was not murdered; it was only a prank: Alissa hid in the storage space under the floor and stuck out her head; the "body" they saw was not hers but a dummy's. She likely planned to make her corpse "disappear" and spook Toto while they went to get the key from the staff room. However, Ron and Toto chose to enter the room from the window ledge. Alissa then threw the dummy's head into the pond, thinking that she could leave the room while they went to inspect the head. Again, her plan was thwarted because Ron still checked out the room. Alissa had used a sheet of false blood for her farce, but when she left her hiding place, the hole in the sheet became visible. She hastily had to pull the sheet under a pillar; this gave her prank away, as Ron noticed that the bloodstain had moved without losing its shape.

Thereafter, Toto opens the door. Even though Alissa should be inside, she is not: She attempted to escape via the ledge but did not get far because she became frightened, and she is now stuck on the ledge. Toto manages to pull her back into the room right before she slips and falls.

Toto and Ron later return to Aimee's office where she thanks Toto for the "lesson" he gave the students. Aimee also reveals that she has known Ron since he was a baby because she and his mother Romi have been friends since their days at BLUE.

The next day, Ron reads on the news that three missing detectives were found dead. As it is Saturday, Toto and Ron do not need to go to BLUE, but then Aimee texts them to see her at her office at 3 p.m. Surprisingly, they are not the only ones going to BLUE on the weekend: On the way to the school, they also run into Udy, Marsh, Alissa, Night Bran Jr., and Billie Za Gozzila. Hutter Horn is already there and waves at them in panic when they arrive. He came to BLUE to talk to Aimee about his academic advancement plan, but when he entered her office, he found her collapsed at her table. Immediately, Totomaru and Ron rush to Aimee's office and discover that Aimee was shot and a strange video is playing on her laptop.

### Cryptid Serial Murders Case

Ron orders the students to stay back while he examines Aimee's body; with a heavy heart, he confirms her death. Aimee died two or three hours ago, and the bullet passed through her body and is now lodged in her chair. The murder weapon lies on the ground, empty of bullets.

When Toto and Ron are done inspecting the crime scene, Night tells them that Aimee asked him to see her an hour ago. Alissa was also called by Aimee to help move Billie's pets, and Alissa asked Udy, Marsh, and Billie to assist her. Everyone, thus, deduces that whoever killed Aimee must have called them to BLUE, possibly so that they find her body. This means that Aimee's murder is a declaration of war to Ron, Totomaru, and the students. Alissa and Night are ready to accept the challenge; because both only want to showcase their skills, Toto scolds them.

Then, the academy's guard comes into the office, intending to ask Aimee whether the emergency isolation system is running. When it is activated, the system blocks internet and phone signals as well as pulls the drawbridge. Toto and Ron rush outside to check the bridge, but it was already drawn and because only Aimee knew the isolation system's deactivation code, they are now trapped in the school.

Later, everyone gathers in a lecture hall to discuss why they might have been isolated at BLUE and how to proceed. Totomaru and Ron decide to search Aimee's laptop to find a way to deactivate the emergency isolation system. Marsh offers to help as he specializes in cryptology. He manages to boot up the laptop with another operation system, though fails to disable the isolation system as its control is overridden by a third party. When Toto praises Marsh's abilities and calls him and the others the "future of detecting," Marsh admits that he does not want to become a detective at all as he faints when he sees blood or corpses.

The guard finds them and says that he is looking for the other students. Ron confirms with the guard that no one could have left or entered the school while he was away from his post; the culprit must, therefore, still be at BLUE and is most likely one of their group. They then hear Billie scream and follow the sound and her monkey to the courtyard: Udy lies there. Her lifeless body bears deep gashes, and a piece of paper saying "Chapter 1: The messenger from the sky Wyvern" is next to her. Curiously, only her footprints are visible, and Udy's corpse lies in the middle of the courtyard.

Toto and Ron examine her body and determine that she died about 20-30 minutes ago. Not long afterward, Alissa, Hutter, and Night arrive and are shocked by the scene in front of them; Alissa even faints. Billie, however, is nowhere to be seen. Marsh speculates that she might be in the hidden room under the north building as she once told him that she was considering keeping pets there. Everyone heads to that room; the guard carries the still-unconscious Alissa.

On the way, the students and the guard talk about Ron Kamonohashi who used the room in the past. Hutter voices his hatred of him, as he believes that he works with the M. Family. In the hidden room, they find an ashtray with cigarette butts and strands of blue hair, neither of which belongs to Billie or anyone they know who is inside the school. While everyone discusses what to do next, Alissa wakes up and immediately spots the tenth person under the bed. She wants to attack them, but Ron stops her and tells the person to reveal themselves. To everyone's shock, Chelsea Gadd crawls out. The students have not seen her lately because she was suspended for her obsession with the M. Family. Chelsea is also a fan of Ron Kamonohashi; a fact that rather disturbs Ron and Toto.

Without answering their questions, Chelsea leaves the room, and the others follow her to the courtyard. There, Chelsea identifies the paper lying next to Udy's corpse as a page from an M. Family book. She learned about it from a special "Unsolved Mysteries" class; apparently, that book was left at several crime scenes connected to the M. Family.

Totomaru and Ron re-examine the courtyard before they search the building for clues. Ron also decides that he does not want to reveal his true identity for now as the students likely would not trust him if they found out. Afterward, they go to the home economics room where the students and the guard are about to make dinner; the guard cuts his finger in the process, and Marsh offers to help him with the wound. A moment later, Hutter joins them and brings the food he hid in the classroom. He also snaps at Toto when he remarks that he should have told someone if he wanted to go to the classroom.

Ron inquires why Hutter is treating "Officer Isshiki" so poorly. When she hears his name, Chelsea realizes that Toto is the police officer who was at the Nandan Observatory during the Island Observatory Murder Case and the one "responsible" for John Grizzly's death. Hutter hates Toto for that. Upon hearing about Toto's involvement in that case, Alissa and Night also turn against him and leave alongside Chelsea and Hutter. Toto and Ron decide to search for them and ask Marsh if he knows where they might have gone, but Marsh is strangely avoidant of the topic. Toto realizes that he seems scared to solve the mystery, and Ron points out that Marsh can actually see blood; earlier, he could bandage the guard without problem after all.

Marsh admits that he came to BLUE because he wanted to become a detective. However, he buried that dream when he made a wrong deduction that led to the falsely accused attempting suicide. Marsh then Totomaru and Ron where the others likely are. Ron and Totomaru head to the roof first where they find Alissa crying over Udy. After they convince her to keep going on solving cases for her dead friend's sake, they bring her to the home economics room.

They split up, and Toto heads to another underground room. Although he expected to find Chelsea, only Hutter is in that room. Totomaru takes this opportunity to tell Hutter what truly happened in the Island Observatory Murder Case. When he adds that Grizzly—who investigated without bias and apologized upon realizing that Ron is not the culprit—would be disappointed in him because of his attitude, Hutter becomes angry and grabs Toto's shirt. Totomaru says he can go ahead and hit him, though Grizzly would be mad at him if he could not protect Hutter when he is half-dead. His words knock sense into Hutter. Minigozzi then finds them.

Toto and Hutter meet Ron and Night upstairs, and the monkey guides them all to the locker room. There, they find a locker leaking water. Hutter quickly picks the lock, and they manage to rescue Billie on time who was tied up and placed in the water-filled locker. A cover page has been left with her too. To their horror, it is "Chapter 3: The Terror within the Water Merman," meaning there was another murder while they were searching.

Toto and the others hurry to the rooftop where they find Chelsea's corpse. The cover page of "Chapter 2: The Giant's Awakening Cyclops" lies next to her, and she curiously seems to have died by falling from a high place. They then decide to split up: While Marsh and Alissa bring Billie to their classroom so that she can change her clothes, Toto and Ron as well as Hutter, Night, and the guard will investigate the area. They also agree to meet up again in an hour.

Toto and Ron remain on the roof, and Ron discovers fresh marks on a pole. Baffled by the crime, Totomaru cannot believe a human could be behind it.

An hour later, everyone reassembles in the locker room and shares their findings: Night's team found no evidence that Chelsea fell to the ground, but noticed that the guard station was broken into and the sensors that detect entry and exit destroyed. Ron and Toto found marks on a pole as well as a bloody body bag on the roof. Afterward, they examine the third crime scene, and Billie tells them that she went looking for her pet rabbit and cat earlier. She spotted Udy's corpse from a window and was attacked from behind right afterward. She was knocked unconscious and woke up later in the locker.

Ron lies down in the locker and finds strands of long, white hair inside. Night then whisks Toto and Ron away to the rooftop where Night asks Ron for his deductions. Ron states that he has not solved the case yet, though he realized that "everything will fall into place" if he figures out the trick behind "a certain person's actions." Hearing his words, Night is sure that they are suspecting the same person, and says that he, "Ron Kamonohashi," could truly be a strong rival. A moment later, Alissa arrives on the roof, shocked to have heard that "Kamo Miele" is Ron Kamonohashi.

## Skills and abilities

* **Deductive skills:** Because Toto has rather poor deductive skills, he was only assigned odd-jobs and cases of low importance before he started working with Ron. However, since their team-up, Toto's skills have slowly been improving.
* **Observation skills:** Toto is attentive and observant. He has no problems detecting clues and inconsistencies, even if he mostly struggles piecing them together. Ron even consults him for hints for that reason.

## Quotes

* (To Ron Kamonohashi) "*I want you to believe in Ron Kamonohashi, too. Why would someone who loves solving cases more than anything and has offered up his life to detective work shut himself away for five years?! You stifled yourself because you care about other people's lives, right? That's the kind of person you are!!*"
* "*I'm sorry... Something unforgivable has happened... As you say, the investigation has to continue until we catch the culprit... Thinking back now, we were conceited enough to think that the case had been solved just because we solved the mystery... The two lives that were lost can never come back... I'm so sorry!*"
* (To Elmer Stingray) "*As long as we can catch the one who hurt Haruno-san... It doesn't matter if you're a 'partner' or not.*"

* (To Marsh Leipley) "*I think knowing that fear will make you a great detective. There's a detective I know, and like you, he's had to battle the fear inside himself. He's become a great detective since then, and has saved countless lives.*"

* General
* Anime

* Totomaru's grandmother taught him the sutras.
* He had a pet hamster as a child. The only memory he has from his early childhood is looking at his hamster's back.
* He is a big fan of Nyo-Nyon.
