Tamotsu Fukuda/History

## Background

Much isn't known about Fukuda's early life, however, it's known that he suffered for years on account of his arithmomania. It is also implied that he was an exceptionally lonely man, having no family or close friends.

On August 15th, 2015, Fukuda finally succumbed to the pressure and, at around 2 PM, attempted to kill himself by drilling into his head. However, instead of dying as he had intended, he instead found himself in a hospital room with Kiki Asukai and John Walker, who offered Fukuda the opportunity to drill a hole in the former's head, which Fukuda refused. Next month on the seventh and the tenth, John Walker made the same offer, but Fukuda declined each time, telling him he wasn't interested in "dream holes".

Sometime afterwards, he would begin kidnapping people and drilling holes in their heads as he had done to himself, under the belief that doing so would help them in the same way it had helped him, going on to kill Kenta Obara, Wataru Takada, Eiko Imanishi, Yoshihito Fujita and Masami Kitamura. He would also kidnap and drill Haruka Kazuta, who could actually go on to survive the procedure and escape.

## *ID: INVADED*

### **FILE: 01 Jigsawed**

After kidnapping his seventh victim, Yuji Oonuki, Fukuda's cognition particles are discovered by the Kura, and field agents Koharu Hondomachi and Kokuryu Matsuoka are able to deduce his location based on the information found in his id well. Watching them arrive, he goes into his basement and drills a hole in Oonuki's head, taps the drill to his hand and puts his coat on him, then poses as the victim in order to escape, leaving Oonuki to be shot in his place.

### **FILE: 02 Jigsawed II**

Believing him to be the victim, Fukuda is taken to an ambulance. There, he kills the doctors inside and hijacks the ambulance, hitting Hondomachi in the process. After killing the driver, he exits the ambulance and kidnaps her, fleeing through the sewers to an abandoned restaurant. There, he ties her to a table and waits for her to wake.

After she does, he greets her, informing her that he has multiple hideouts throughout the city. She tries to question why he doesn't kill his victims right away, but Fukuda dodges the question and instead asks how the wakumusubi works, threatening her with his drill and stating that few can answer his questions after they've had a hole drilled into them, which intrigues Hondomachi, who presumed they all died instantly, which Fukuda shoots down, claiming that Oonuki could live as long as him, assuming he wasn't mistakenly killed.

Hondomachi deduces that Fukuda likely drilled a hole in his own head first, and asks why. Elaborating, he explains that his hole allows him to see the world clearer. Disgusted that he thinks he's helping people, Hondomachi denounces him as nothing but a killer, and that her colleagues will find and arrest him. Ignoring her, he again threatens her with a drill and asks about the wakumusubi. Finally giving in, she explains the origins of its name, but when he doesn't reply, she grows frustrated and pierces her own head with the drill, to his surprise, which triggers the wakumusubi.

Realising that the device detects the intent to kill, he thanks Hondomachi for helping him realise that his methods didn't help people because they need to drill their own holes, as he did. She wearily asks if he really drilled his own head, to which he states he felt like he had to, asking her how the breeze is. At that moment, the police burst into the room, and Fukuda easily gives up, asking Hondomachi to visit him if she recovers.

### **FILE: 03 Sniped**

After Akihito Narihisago is called by the Wellside, Fukuda greets him as he walks by his cell, and asks where he's going, only to be ignored.

Later, Fukuda listens from his cell as Narihisago induces Koji Huyukawa to commit suicide by exploiting the psychological weaknesses he uncovered in his id well.

### **FILE: 04 Extended**

After Narihisago is placed in solitary confinement as punishment, Fukuda is interviewed by the Kura and Wellside, where he reveals that he has deduced the existence of the Mizuhanome System based on Narihisago's knowledge of personal information that he shouldn't know and his ever-darker demeanour, telling them that they should have heard his voice, calling it simultaneously a whisper and a deafening scream. Realising the extent of his intelligence and with Takuhiko Hayaseura's approval, the Wellside recruit him as a Mizuhanome piolet to see if he can work as a possible substitute for Narihisagio/Sakaido, leading to the birth of Brilliant Detective Anaido.

However, after a trial run of multiple id wells over three days, it becomes apparent that Anaido has an abnormally low survival rate. Ejected for the last time, Fukuda snidely remarks that someone who drilled a hole in their head would have a low rate of survival. When cognition particles are discovered at the scene of a "Gravedigger" scene are found to the first time, Narihisago is brought out of solitary to enter the id well. As the two swap places, Fukuda cordially greets him, the latter ignoring him in turn.

### **FILE: 05 Fallen**

After Fukuda's only other surviving victim, Haruka Kazuta, comes into contact with Hondomachi, Fukuda is interviewed by Funetaro Momoki to try and gain more information. Fukuda warns him that though they both have a hole, they aren't the same, and that the next time they see Kazuta, they should ask him if the wind blowing through his hole is cold, and that, based on his own experience, if it isn't, then it means trouble.

### **FILE: 06 Circled**

Fukuda is mentioned by Matsuoka, who recommends Hondomachi take his place as Narihisago's substitute, given Anaido's near uselessness.

### **FILE: 07 Thunderbolted**

Noticing Nahoshi Inami in the cell opposite him, Fukuda expresses his surprise that there are men and women in the same cell block, saying she should file for grievances, only for her to reveal she requested it, to his amusement. She asks how he got his injury, and, when he asks what she thinks, says someone drilled into his head, but Fukuda corrects her: he did it himself. Inami is surprised he's still alive, with Fukuda admitting he must have been lucky, though he mentions two other people who survived as well. When Inami realises he's done the same to others, Fukuda asks if she's met someone like him, to which she reveals she's met two, and admits that Kazuta's hole helped the two to connect, with Fukuda agreeing, saying the holes bring liberation. However, she mentions the second one, Honodmachi, killed him. Amused, Fukuda notes how she's working overtime.

He then looks over at Narihisago, who soon starts to bang his head against the wall in frustration, to Inami's surprised. Fukuda observes that Narihisago needs to change the way he thinks, offering to help him if he had a drill. As he continues banging his head, Fukuda tells him that it won't stop the Mizhanome, which Narihisago already knows. Fukuda tells him to calm down, calling him "brother", only for Narihisago to yell at him to shut up as the guards arrive to stop him.

### **FILE: 08 Desertified**

After Hondomachi's brilliant detective, Miyo Hijiriido, enters a Mizhuamome cockpit within Narihisago's id well, thus trapping Hondomachi in "Kiki Asukai's well-within-a-well", Anaido is sent in multiple times to try and save her. After over twenty deaths, Fukuda is pulled out, with Sarina Togo noting his improvement and Fukuda bemoaning the sensation of being struck by lightning. Togo reassures them they're watching his vitals, mentioning his heartbeat is becoming irregular, but Fukuda tells her to not pretend that they care about him, and reports that he saw the cockpit, asking if he should go try and reach it. Togo tells him it's not necessary, to his relief, only to reveal that they're going to put him into a different well: Momoki's, under the theory that his id well also has a Mizhuanome cockpit, with the Wellside planning to send in two brilliant detectives so one can eject and retrieve the pilot, who searches for Hondomachi in Asukai's well.

As Narihisago arrives, Fukuda greets him, asking how to feels to have him wandering around his subconscious, to which Narihasago bluntly states it has no effect on him. Fukuda agrees that as a reflection of his intent to kill from years ago, it can't contain his entire psyche, but ominously notes that such an intent is the core for serial killers like them, and that it could be used to drive someone to suicide. The guard orders them to be quiet, which Fukuda protests. Togo then explains to Fukuda and Narihisago (who she addresses as "Mr. Narihisago", to Fukuda's amusement) that they will dive into the same well together, and asks them to work together, even though they'll be strangers.

Fukuda then asks if two brilliant detectives means that there will be two Kaerus, to which Togo admits they don't know, having never attempted something like this before, reassuring them that they'll be extracted if there is any danger. He then asks if she's read any mystery novels, going on to explain that in classic detective literature, there are rarely two detectives since there is only one solution, meaning one detective's solution must be wrong; the first detective uncovers the mystery, only for the second to peer deeper and unravel something even greater, though he doesn't rule out the possibility of the first detective deliberately lying. Regardless, this means that one of them will be wrong in their deductions, and wonders how that will affect the id well. Togo then dismisses this, stating they don't have the time, and orders them to dive in.

### **FILE: 11 Stormed**

A recreation of Fukuda appears in Kiki Asukai's id well, who Hondomachi confronts, using her experience of being kidnapped by him in the real world to find his hideout. She confronts him, claiming to know all about him, which he mocks, until she reveals his suicidal tendencies, and that she also put a hole in her head. Intrigued, Fukuda admits she's telling the truth, and asks if she enjoyed her hole. After she tells him that she feels incomplete without it, he says it suited her, and although she doesn't agree, she admits that it had become apart of her. Fukuda remarks on the irony of losing a part of oneself to feel complete, before asking what she came here for.

Hondomachi then asks him about his dreams, holding a sketch of John Walker and asks if he's seen him in his dreams. Fukuda confirms he has, the first time being August 15th three years prior, with subsequent sightings on September 7th and 10th later that year, impressing Hondomachi with his memory and admitting he used to be proficient with numbers, elaborating that on August 15th he specifically saw John Walker at 2-3 PM, and that September 7th and 10th were 11 PM to 3 AM, detailing his meetings with John Walker and his refusal to kill Kiki Asukai. Hondomachi looks into it, but disappointed notes that everyone with access to the Wellside was on duty the afternoon of August 15. Fukuda suggests that the person playing John Walker could have been sleeping, which Hondomachi initially dismisses, until he explains that the person didn't have to be in Japan, and could have been on an overseas work trip. As Honomachi investigates the records, Fukuda asks if she's a cop, and if they'll ever meet again. Honomachi confirms she is, and promises him that being caught by the police will open up new opportunities, to his amusement.

After checking the employe records and confirming that a high-ranking officer went to New York on August 15th, Honomachi calls the Kura Chief Hayaseura, confirming his identity of John Walker. Immediately after, she is pulled from the id well by Anaido, thanking Fukuda for his help. Initially shocked, Fukuda accepts her gratitude as the police close in on his location.

After the brilliant detectives escape the id well, the real Fukuda wakes up, along with Narihisago and Honomachi, who reveals John Walker's identity, just as the Mizuhanome's power is cut.

### **FILE: 12 Channeled**

With communication to the Wellside cut, Fukuda and the other Mizuhanome pilots stand, having no idea what's going on until Hayaseura arrives and shots Narihisago in the stomach, incapacitating him. He then turns his gun to Fukuda, forcing him away from his cockpit before shooting himself multiple times. Hayaseura explains his motives, believing that his creation of serial killers helped to establish the Kura as an organisation, revealing that he has turned the entire building into a giant Mizuhanome to maximise efficiency. He then kills himself and enters his own id well. Narihisago and Hondomachi immediately run to their own cockpits, but Fukuda remains where he is, despite Honomachi calling him to go with them. He reluctantly agrees to go along when Narihisago orders him, however both he and the guard with them pass out when Kiki Asukai's influence reach them.

He ends up in Hondomachi's id well, which is eventually invaded by Uraido, Hayaserua's brilliant detective, followed by Hijiriido and Sakaido from the sky, with Hijiriido's realisation of her identity triggering a well storm. Uraido and Sakaido then leave as Hijiriido continues to descend, but Fukuda manages to catch her. The two then leave and return to Hayaserua's central id well, unknowingly followed by Inami.

After crashing down, Hijiriido thanks him and asks how he remembered the steps to Kaeru, with him confessing his affinity for numbers. Hijiriido then tells him she's going after Uraido, and asks if Fukuda will come with her, and while he admits he might if he was Anaido, as Fukuda he has no ability or reason to follow, instead intending to explore Hondomachi's id well. Hijiriido then asks for his opinion on the number seven. He says it's not a bad number, but calls those who like it pretentious, due to the unearned societal weight it has. Her question answered, Hijiriido throws her mask away for Fukuda to chase after. However, he notices Inami aiming at her with a gun, and at the last moment pushes her away, taking the hit himself as he tells her that one hole is enough.

As he lies on the floor bleeding out, Fukuda admits he intended to shout out "Here's my chance!", but that it somehow came out wrong. Hijiriido interprets his "one hole" line as an innuendo, but he assures her it wasn't. As Inami approaches them, Fukuda thanks Hijiriido, as she helped him fulfil two of his wishes. Hijiriido then reveals that ever since she received her hole, she hasn't seen his scar, and that anything "missing" or "broken" instead appears to her as complete and whole, which was how she was able to find and arrest Inami. Fukuda tells her that she would have loved to see his id well, and realises that her no longer seeing his hole means that three wishes have been granted. He finally dies, marvelling at what a fine number three is.

### **FILE: 13 Channeled II**

After Uraido is defeated and Kiki Asukai returned to the Mizuhanome, all those who survived the id wells, including Narihisago and Hondomachi wake up. Honomachi immediately checks Fukuda's body, and weeps upon seeing that he is still comatose, though she stops after one tear, claiming that it's enough for him.
