Birthday: April 1st Ability: <The Overcoat> A space manipulation and object teleportation ability that connects spaces through his overcoat. Although it has a range limit of approximately 30 meters, it boasts overwhelming versatility and utility. It is not an exaggeration to say it is classified as a Special Grade 1 dangerous ability. His colleague Sigma even evaluated it as a "transcendent ability capable of anything." A man with a diamond-patterned eyepatch over his right eye and a long vertical scar over his left eye. Because he usually wears an eyepatch and the manga is in black and white, it is hard to notice, but he has odd eyes with different pupil shapes. His personality appears lively and frivolous, but he is closer to a psychopath. He uses a quiz-like speaking style and many exclamation and question marks. He enjoys killing people and uses cruel methods to the point where the victim would rather be killed. In fact, when Atsushi asked 'why he kills people and why in such a cruel way,' he replied, 'Because it's fun.'

Birthday: November 11th Ability: <Crime and Punishment> Unknown, as details like age, height, weight, and blood type have not been revealed. No one in the story knows what his ability is. Even Dazai is said not to know. However, he has stated himself that it is not an ability to manipulate space or consciousness. That said, there are scenes where he uses his ability; while taking down Port Mafia executive A, he told the subordinate boy Karma, 'I will show you my true ability,' and upon touching his head, Karma died spitting blood. Given that a Special Operations Division member died instantly after touching Dostoevsky, it is certain to be an ability capable of direct killing. It is presumed to be an ability that can injure or kill living beings upon contact. Some speculate it is an ability to absorb the life force of the target, based on Fyodor's frail constitution and the fact that his appearance hundreds of years ago is almost identical to the present. A man who wears a white ushanka, has a pale face, always uses polite speech, and is characterized by a peculiar, unpleasant smile. He is a figure who uses schemes that seem to manipulate human psychology rather than crushing enemies with combat prowess.

Ability name and birthday unknown. An ability to 'exchange the information he most wants to know with the information the opponent most wants to know.' It appears to be activated through physical contact. Information is transmitted into each other's minds like psychometry. It also works through contact with a corpse, but only if they have recently died. While not suited for combat, it is an ability with high potential for abuse in crime. Consequently, he has been exploited by various criminal organizations and has repeatedly fled after being targeted for disposal because he knew too much once his purpose was served. As the general manager of the Sky Casino floating in the air, the casino he operates is a kind of independent nation, so even the Hunting Dogs cannot exercise police powers there. He has an extraordinary affection for the casino. While those around him evaluate him as a flawless genius born solely to manage the casino, he mentions that he actually has no such talent and is an average person with average stats who is an extreme hard worker. He memorizes passenger information to give appropriate instructions immediately, which involves staying up all night memorizing the names and information of all employees and passengers to act out his flawless persona. Also, fitting his self-evaluation as an average human, when his inner thoughts are frequently depicted, he shows emotional aspects and clumsy traits unlike other members of The Decay of the Angel. In other words, he has the 'only sane person' attribute. He has a naive personality. A man who is gentle and kind at heart, living with the thought that he doesn't want to be taken advantage of by others, but also aware that he is weak. He is full of clumsy charm.
