## Biography

### History

When Amamiya was still a novice police officer, she worked at the same police box as Omito Kawasemi.

### Metropolitan Serial Drownings Case

At the Metropolitan Police Department's headquarters, Amamiya investigates the Metropolitan Serial Drownings Case with her division. When she learns that the killer claimed their fifth victim, she orders her subordinates to widen their search area and tells Totomaru Isshiki to go home as his incompetency will only be a nuisance.

Amamiya later calls Toto to order him to go to Kazahana Park; a sixth victim was found there, and he is the closest to the crime scene.

### Locked Room Piggy Bank Theft Case

When the First Investigative Division receives a call that a corpse was found by a river, Amamiya sets out to investigate the crime scene. Toto wants to come as well, but she refuses and assigns him to a different case: the "impossible" crime of the Locked Room Piggy Bank Theft Case.

Still, to her displeasure, Totomaru later joins Amamiya by the riverbank and has even brought an outsider, Ron Kamonohashi, with him. Ron states that Toto will solve the murder; thinking this to be a joke, Amamiya informs Toto that if she is not satisfied with his reasoning, she will fire him.

Amamiya listens to Toto's surprising 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. As soon as the older sister confesses to the crime, Ron tells her that she has "no right to live in this world," and his "cool" demeanor catches Amamiya's interest. When Ron pressures the older sister to drown herself in the river afterward, Totomaru first holds Ron back and tells Amamiya to go after the older sister. However, she escapes Amamiya's grasp, and Totomaru jumps after her himself and saves her.

Back at the Metropolitan Police Department's headquarters, Amamiya informs Toto 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.

### Benizome Hot Springs Murder Case

Amamiya wins a weekend at the Benizome Hot Springs, and heads to the annex after a long workday.

Joyfully proclaiming that she will become police superintendent general, Amamiya walks into a hot spring and does not that Ron and Toto are bathing there until it is too late. When she realizes that she, in fact, accidentally entered the men's bath, Amamiya quickly leaves.

Afterward, Amamiya goes to the lounge and gets drunk. There, she overhears Sachiko telling her husband that they should get a divorce, and Amamiya, while crying, tells them not to get a divorce. She then goes 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, Amamiya approaches Toto and struggles to thank him for proving her innocence. Further, because there is still doubt about her, she cannot investigate this case and puts Totomaru in charge.

When Toto happily says he will do his best to meet her expectations, Amamiya angrily replies she has no expectations of him; he is simply the only other officer around. She then gets frustrated over the "ridiculous" things that keep happening to her: First, she walked into the men's bath. Now, she has to rely on Toto. Hearing this, Ron solves the case and thanks her for the reminder. Seeing Ron push his bangs to the side makes Amamiya blush and faint; Toto catches her.

Later, Amamiya is present when Totomaru gathers everyone to tell them 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.

The husband confesses to the murder and tells his affair partner Michiyo that he did it for her. She does not want to hear his excuses though, and Amamiya arrests the husband.

### Hand Collector Killer Case

Amamiya informs Totomaru 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, and she hates Kawasemi and does not want to give him her best men.

When Kawasemi arrives, he tries to pick up some dust on her shoulders. Amamiya grabs a pen and threatens to slit his throat if he dares to touch her. She then tells Kawasemi that Toto will help him and Yamane with the investigation. However, because of Toto's incompetence, Kawasemi has already erased Toto's existence in his mind. This makes Amamiya point out what a great boss she is in comparison.

After the case is solved, Kawasemi tells Amamiya in his thoughts that she has a great subordinate, causing her to sneeze at police HQ while she is eating. Angry that she dropped her meat, Amamiya demands to know which "idiot" is talking about her.

### Live Broadcast Murder Case

After someone is murdered at Donut Television, Amamiya leaves a message for Toto at the studio: "Everyone else is busy, so you handle this, you loafer."

### Poisoned Latté Case

Toto gives Amamiya a souvenir from his trip to Nandan Island. Without looking at it, she thanks him and then proceeds to tell him that she has prepared a job for him; he will find it in the conference room.

### Mad Chameleon Murder Case

When Amamiya finds out that Kawasemi is in a slump, she sends Toto to Nagoya; officially to make a report on regional crime patterns, inofficially to see how badly Kawasemi is doing so that she can hear the "death throes" of his career.

One week later, Amamiya notifies Totomaru that Kawasemi cross-examined all the victims in the Mad Chameleon Murder 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.

### Shibuya Revelation Serial Murders Case

One morning, Amamiya takes Totomaru to the Shibuya Mall Park to investigate a case. Surprisingly, 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 Amamiya and Toto that the victim died of blood loss and that they do not know how the murderer escaped after committing the crime because the security officer did not see anything suspicious yesterday and found the body this morning' the anti-intrusion sensors did not detect anything. Amamiya theorizes the culprit might have taken a different route than the officer, evaded him, and escaped before the sensors were activated at midnight. The officer says this cannot be as the victim died around 2 a.m.

Later, Toto "solves" the case and tells Amamiya the murderer's trick: 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.

Amamiya then inspects the corpse, now identified as Ryouji Katsunami who belonged to a three-man hacker group, and wonders what the strange marking (0 10:00) left on his neck could mean. Ron says the mark is announcing the next murder and that the culprit wants to see all three hackers dead. As it is currently 9:30 a.m. and they only have 30 minutes to determine the next crime scene, Amamiya calls for back-up to find out what the "0" means.

She later receives a call from Totomaru who tells her that he has secured the third hacker and will use him as bait at the Delta Hotel to lure out the murderer. Although Amamiya replies that the top brass would never approve of such a thing, she still arrives in disguise at the hotel. She finds Totomaru and informs him that a peculiar alloy was found in the tip of the arrow that was used to kill Hibino. She and her team lost sight of the third hacker, but the triangle on the arrow led them to the hotel where they "just happened" to find out about the trade with the murderer. As they are already here, they might as well apprehend them. Amamiya adds that if the police spots the hacker before 11 a.m., they have no choice but to protect him. When Toto asks her why she is helping them, she replies that she cannot let this "psycho" who killed two people in the middle of Tokyo run wild and free.

Shortly after 11 a.m., the third hacker runs out of his hideout and into the lobby where he would have been buried underneath a chandelier if Toto had not saved him on-time. Music then starts to play from the hotel's speakers. Totomaru informs Amamiya that the music is part of the murderer's plan: Haydn's 96th Symphony is known as the "Miracle Symphony" because, during its first performance, a chandelier fell but no one was injured—just like earlier. In turn, Amamiya tells Toto and Ron that the tip of the arrow is made of iridium. She then takes the hacker to the Metropolitan Police Department to guard him.

Unfortunately, the third hacker is actually the culprit Winter Moriarty in disguise. He kidnaps Amamiya and brings her and the real third hacker to the first-floor storage room of the Shibuya City View Tower. He ties both up and wraps bombs around them. At 12 a.m., Amamiya and the hacker are supposed to be blown up, but Spitz Feier can save them on time.

After the Shibuya Revelation Serial Murders Case is resolved, Amamiya notifies Toto that the third hacker committed suicide. Totomaru suggests that she should take a break after everything that has happened, but she brushes him off as she feels more at ease at the headquarters. Amamiya adds that she noticed that the clerk from the Benizome Hot Springs now works for "Kamoo's" sweets company before she tells Toto to verify the culprit's corpse.

### Psychological Research Lab Murder Case

Amamiya investigates Kanae Himeno's death at Tokyo University when Toto surprisingly arrives. Toto informs her that he knew Himeno, and Amamiya tells him what the forensic analysis found out: The shield room was filled with flammable gas. When the door was opened, the gas touched an external heat source, presumably a heat gun, and exploded. Because flammable gas is never used in the experiment room and a heat gun would have never been left out, Himeno's death is treated as a homicide.

Totomaru requests to be assigned to the case, and Amamiya reminds him not to bring personal emotions to work. She, however, changes her mind when she remembers an event in her past. Amamiya fakes that she received a call for something "urgent" and leaves the case to Toto.

### Fortuneteller Prince Murder Case

Toto calls Amamiya after discovering a corpse at a book signing. She sends out officers to the crime scene and makes an officer relay a message to Toto: He should do his job. She also complains about why Totomaru is the only one who gets to "play around" at auberges and signings.

### Severed Head Balloon Case

On her monthly maintenance day, Amamiya encounters Totomaru at the mall. 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 despite Amamiya's protests that she is not "presentable" right now. Ron, however, replies that he is busy right now. Amamiya and Toto 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.

Amamiya and Toto 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, Amamiya and Toto 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 Amamiya's and Toto'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. He also 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.

Not long afterward, Ron leaves and wishes Amamiya and Totomaru good luck arresting the culprit. Totomaru then tells Amamiya that he "believes" they have already met the culprit and points out the half-eaten popsicle that Ron left behind, 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 notes that this is not enough to catch up with Kawasemi. Nevertheless, she 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. Afterward, Amamiya heads home to wash her face because she had put on makeup being the backup arrived.

### Twin Prison Locked Room Murder Case

Shortly after solving the Severed Head Balloon Case, Amamiya is called in to investigate the incident at the Moon Prison. She immediately heads there and inspects the place and the corpse.

Sometime later, Ron and Toto arrive, and Amamiya is thrilled to see "Kamoo." She 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.

Afterward, Amamiya briefs Fin about the case and gives her the Moon and Sun key to examine. Only by touching the keys, Fin confirms that they are the genuine items which amazes Amamiya. She invites Fin to touch the inside of the prison as well and offers her help if she needs it. Fin thanks her and excuses herself to talk to Ron and Totomaru.

To Amamiya's disbelief, Fin solves the mystery as soon as she finishes examining the prison. Fin 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. However, to Amamiya's shock, Fin does not reveal the culprit as her only goal was to solve the locked room's mystery. She leaves the rest to the Metro Police and returns with Shachi to their guesthouse.

The next day, Amamiya calls Totomaru to inform him that Kaji was found murdered in the Moon Prison. She later rejoins Toto, Ron, and the others at the Moon Prison to listen to "Toto's" deduction. Amamiya asks Fin why she is not doing it, and Fin replies that she only supported his approach and would like to see how he solves the case.

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.

### Missing Cabbage Case

When Toto arrives at Ron's apartment, Amamiya opens the door for him, surprising him. She explains that "Kamoo" invited her, though she wanted to leave upon seeing that Kawasemi is here too. Amamiya's and Kawasemi's presence baffles Toto because Ron wrote him a message about an urgent matter. Ron admits that he exaggerated in his message to ensure that Toto would come because it is his birthday today. Only when Amamiya, Ron, and Kawasemi congratulate him does Toto realize that it is indeed his birthday.

When Chicory Monki and Mofu Usaki 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.

In the meantime, Chicory, Mofu, and Ron prepare the other vegetables. When Mofu's knife slips out of her grip and gets stuck in the ceiling, Amamiya takes over, understanding that Mofu must be exhausted as the world's top neurosurgeon. Chicory remarks how kind and earnest Amamiya is and that it is no wonder that she is Totomaru's superior. Amamiya is flattered by the compliment but tells Chicory that she will not give her any information for her magazine.

In the background, the television is running: A news broadcast announces that a jewelry store in Tokyo was robbed this morning. Then, Amamiya and Kawasemi 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, Amamiya, Ron, 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. Everyone roots for Toto and awaits his deduction—only, he has no other idea than his kimchi one. Stressed, 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 the 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

Amamiya practices *kyūdō* at the Shingen Archery Dojo, with Toto watching her. Because Ron became interested in checking out her dojo, he arranged to meet up with him and Amamiya there, though he runs a bit late. When he finally arrives, he stuns Amamiya and Toto with his archery skills. He even receives praise from Mayumi Nakamae, an instructor.

Nakamae invites them to watch her pupils practice. 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 Amamiya, Totomaru, and Ron about Nora's infamous incompetence as the district detective.

After they leave the kyudojo, Ron suggests to go eat together. Just when Amamiya agrees, she receives a call from the Metropolitan Police Department: They need her for a case. Begrudgingly and in tears, Amamiya says goodbye to Ron and Toto and quickly leaves.

The next day, Shu Kotegawa's corpse is found at the Shingen Archery Dojo. Because the Metropolitan Police Department is called to investigate, Amamiya heads to the kyudojo. 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. There is also blood on Kotegawa's index finger. He seems to have left behind a dying message, but nothing is written on the ground.

When Amamiya eventually arrives, she is displeased by Nora's presence 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 to teach him a lesson.

After Amamiya lets Nora go and he 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."

### Coin and Carving Murders Case

Though Toto has already been assigned to the Coin and Carving Murders Case, Amamiya calls him with another "urgent request": In her stead, he should meet Hirsch who is currently in Japan to lecture on forensic medicine at the university.

### Tragic Cruise Serial Murders Case

At the Metropolitan Police Department's headquarters, Amamiya calls for Toto, and one of her subordinates has to remind her that he is taking a weeklong vacation. Because he rarely takes days off, Amamiya thought he was joking when he told her about it. Though she states that everyone has "the right to some time off," Amamiya takes a pillow to scream into it because Totomaru is taking his vacation during a busy time.

When Totomaru is hospitalized in Okinawa a few days later because of the events aboard the *Precious Dolphin*, Amamiya rushes to his side. She also visits Ron at the hospital on the day of his discharge. She even made him an apron with a "real Kamonohashi" on it, though Totomaru thinks it is an "imaginary alien monster."

Amamiya is happy when Ron lets her know that he likes the gift. Unfortunately, she is called back to work right afterward, and she leaves in a hurry.

### Ron Kamonohashi's Homecoming Case

Amamiya—while simultaneously apprehending a criminal—says goodbye to Ron and Totomaru who are, as far as she knows, leaving for London for a sweets training trip and the World Detective Alliance's training respectively. She hopes Ron will return safe and sound and gives him and Totomaru good luck charms that have been passed down in her family for generations.

As she has to bring the criminal to the Metropolitan Police Department, Amamiya leaves.

Amamiya has a crush on Ron who she respectfully calls "Kamoo-sama," even after learning that it is not his real name. She often blushes in his vicinity, when she thinks of him, or when he compliments her. She also greatly values Ron's opinion, such as when she was afraid he would think her a pervert after she had mistakenly entered the men's bath. Like Ron, Amamiya owns clothing depicting sweets; on one occasion, she wore a shirt with "Kasiwa moch" (Kashiwa mochi) written on the back, with a small image of the confection under it.

Further, Amamiya thinks it is "cool" when he tells murderers they have "no right to live in this world," and that it is "supremely cute" when he pushes his hair to the side.

However, when Amamiya first meets him, she expresses dissatisfaction at having Ron, a stranger, loitering around a crime scene and thinks he is a loser because he is Toto's friend. Amamiya only becomes interested in him upon seeing Ron unconsciously activating Kill on Sight.

## Etymology

* The surname "Amamiya" means "rain" (雨, *ama*) and "temple, shrine, palace" (宮, *miya*).

## Trivia

* Amamiya's dream is to become police superintendent general (the chief of the Metropolitan Police Department).
* She is a sad drunk.
* She loves ice cream.
* Amamiya takes a maintenance day once a month to relieve stress. On that day, she goes to the mall where she works out in the gym, gets a massage, and a haircut. She cannot "get by" without her maintenance days.
* Good luck charms have been passed down through the Amamiya family. Apparently, Amamiya owns "a thousand" of them.

### Out of Universe

* Like most important characters, such as Ron and Kawasemi, Amamiya has an "animal"-related name. Akira Amano has not given it yet, as it feels more fitting to her to call Amamiya just by her surname for now. Amamiya's first name may be revealed later on.
* Amano thinks that Amamiya is a "fun character to draw" but also a character that can be easily misunderstood because she seems so "grumpy" and is often hard on Toto. She likes that Amamiya is so honest and works hard.
