**Dr. Mofu Usaki** (卯咲 もふ, *Usaki Mofu*) is the world's top neurosurgeon. She does surgeries on a microscopic scale and performs at least 800 surgeries a year. Mofu also stars in the liveshow "Lie or Truth? ESP!!"

## Physical description

Mofu is a slim young woman with a fair complexion, pinkish purple hair that falls to her chin, and eyes of the same color.

Due to her clumsiness, she is always covered in bandages and plasters; commonly, there are bandages wrapped around her head, and her right eye is covered by a cross-shaped plaster.

Casually, Mofu only ever wears dresses or shirts paired with skirts. To work, she wears a white coat over her attire.

## Personality and traits

Mofu is a genius who is hyper-specialized in medicine. However, when it comes to other matters, she is extraordinarily clumsy; Ron once remarked that she is "blessed by the god of clumsiness." Because of that, Mofu has problems with simple activities, e.g. applying makeup or cooking, and frequently gets caught on objects and trips. Her extreme clumsiness leaves her perpetually injured and covered in bandages.

When it comes to her work, Mofu is very earnest and focused. To her, human life is invaluable, and she dislikes it when people make light of others' lives.

## Biography

### History

At some point, Mofu had a patient whom she could have saved. However, because said patient refused treatment and believed the power of ESP would save them, they passed away. Since then, Mofu has made it her duty to correct society's misunderstanding concerning ESP.

### Live Broadcast Murder Case

In the latest episode of "Lie or Truth? ESP!!," Mofu has to face off against Dankichi Torage, a self-proclaimed psychic. Torage claims that he can control someone's brain using only writing with the power of ESP. To demonstrate his ability, he picks a volunteer from the audience. The volunteer is given noise-cancelling headphones, and Torage shows him multiple cards on which he has written a word. Apparently against his will, the volunteer executes the commands. Though the host Onoyako and the audience are stunned, Mofu objects. She calls the display a "mockery of neurology" and questions whether the test subject was truly randomly chosen because she has analyzed the man's movements and figured out that he is the same test subject who was chosen the last time.

To show that Mofu's accusation is false and that he does possess ESP powers, Torage writes "death" on a card. As soon as he shows it to the volunteer, he collapses. Torage checks the man's pulse, and after he declares him dead, filming is stopped and an ambulance is called.

The situation deeply saddens and upsets Mofu because, as a doctor, it is her responsibility when someone dies right in front of her eyes. When Totomaru Isshiki and Ron Kamonohashi later arrive to investigate the scene, Mofu informs them that she examined the test subject and found out that he was poisoned, likely with a nerve poison. To her surprise, Ron agrees; he thought the puncture wound on the man's neck could be from a poison needle. After Ron assures her that Torage did not use ESP but a trick and that "Toto" will uncover it, they watch the show's recording, and Mofu tells 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.

Afterward, Mofu's bandage gets stuck on a handrail, and Totomaru frees her. Mofu thanks him for today and remarks that his "brilliant deduction" is going to save many lives. In turn, Toto apologizes for Ron's behavior and informs her about his habit of pressuring murderers. To her, it did not seem like "pressuring" though. Before Mofu can reply, Toto thanks her for cheering him up and leaves.

### Mad Chameleon Murder Case

Ron seeks out Mofu at the East Japan Integrated Hospital to find out more about Kill on Sight. She tells him that, according to the test results, his ability is not something hereditary. To get a complete examination, Mofu then writes Ron a referral letter to the Aichi Research Center.

### Midsummer Beach Hut Drowning Case

When Mofu is kicked out of her condo for damaging it with her clumsiness, Ron suggests that she moves into the Maison du Kamonohashi. On the day of her move, Mofu encounters Toto. Together, they head to Ron's flat where Mofu informs Toto that she has developed a way to suppress Kill on Sight. However, because he has to take a combination of various experimental medicines, this method is not particularly safe, and Mofu only allows him to take the medicine in her presence.

During their conversation, Mofu receives a call from Shikada who tells her that she has a surgery scheduled for today. She thanks Ron and Toto for the tea and leaves. Shortly afterward, Mofu learns that her surgery was cancelled. On her way back to her flat to take a nap, she runs into Ron and Totomaru who invite her to go to the beach with them; Mofu accepts.

At Natsukaze Beach, 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. Mofu finds a corpse behind some rocks. Because she gets her foot stuck in the rocks, she waves Ron and Totomaru to her. They and some surfers rush to her side. The surfers immediately identify the dead man as their missing friend Taku Manba, and Ron deduces that he was murdered.

After the local police arrive, Mofu informs an officer about the result of her autopsy, and Toto explains the situation to him: 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.

When the officer suggests that Manba must have tried to surf drunk and drowned, Ron draws attention to himself by objecting: Manba was murdered because he is wearing oversized diving clothes, not surfing clothes. To quench the officer's suspicion, Mofu claims Ron to be her assistant who loves mystery and wants to be a detective. Afterward, Mofu and Ron reveal to Totomaru that she knows about their secret, and Mofu gives them her full support.

Thereafter, Mofu, Toto, and Ron question the beach hut owner about what he did last night: He cleaned up the shop, went home, and 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. He then asks Mofu for permission to take the medicine. After she gives it, they 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.

When the beach hut owner says that he will confess if his sentence is lightened, Mofu slaps him for making light of a person's life. Because of the medicine, Ron does not compel the beach hut owner to commit suicide. Mofu and Totomaru are happy that it worked, but the joy is short-lived: Ron suddenly calls Toto and Mofu "Max" and "Molly" before he passes out. Totomaru later begs Mofu to allow Ron to take the medicine even if she is not there, and she gives her permission for it.

### Missing Cabbage Case

After Mofu drops some *enoki* and accidentally kicks it on top of a stray cat's head, it attacks Toto. She apologizes for the mishap, and a moment later Chicory Monki arrives and inquires if she is well. Toto is quite surprise 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, Mofu and Chicory leave to do some "pressing" business.

They later join Toto, Amamiya, and Omito Kawasemi at Ron's apartment and wish Toto a happy birthday. For the special occasion, Ron called 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 Feier to search a bit farther away.

In the meantime, Mofu, Chicory, and Ron prepare the other vegetables. After Mofu's knife flies out of her hand and gets stuck in the ceiling, Amamiya offers to take over, understanding that Mofu must be exhausted; after all, she is the world's top neurosurgeon.

In the backgound, the television is running and 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. Everyone 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.

### Tragic Cruise Serial Murders Case

Following the events aboard the *Precious Dolphin*, Toto and Ron are hospitalized. When Mofu visits Totomaru, he gives her the flash drive Mylo Moriarty left behind which contains all information on Kill on Sight and asks her to analyze the data.

On the day of Ron's discharge, Mofu visits him and Totomaru at Ron's apartment. She informs them that she has finished the analysis and determined the cause of Kill on Sight. With that information, she is confident that she can cure it by treating Ron's brain. When Spitz arrives shortly afterward and tells them that the World Detective Alliance overturned Ron's punishment, Ron is so overjoyed by all the good news that he collapses to the Floor of Sloth.

### Ron Kamonohashi's Homecoming Case

Because of what happened the last time they travelled, Mofu gives Ron and Toto her "good luck" sachet before they depart for England. She also assures Ron that he does not need to worry about his illness anymore. Further, while Ron and Toto are gone, Mofu and Chicory look after Ron's cat.

## Etymology
