Fyodor dostoyevsky

Guilds hidden assets, stealing the Port Mafia documents, and recruiting Mushitaro Oguri, he then starts the operation named "Cannibalism" by poisoning the leaders of the Port Mafia and the Armed Detective Agency through the virus ability of one of his subordinates. He then encounters Dazai, to whom Fyodor reveals his true goal: to find the powerful book that can make anything written in it become reality in order to eliminate all the ability users on earth. He then has a sniper shoot Dazai and tells Dazai that his vitals weren't hit because he still has a part to play in his plan. His operation forces both the Agency and the Mafia to fight against each other, but ultimately, thanks to the efforts of many, the ability user of the virus is found and stopped, releasing the two leaders from the virus. Despite all of this, Fyodor manages to escape, but he is then found by Dazai and Fitzgerald, who used the Eyes of God to find him. In the end, Fyodor gets caught by the Special Division of Unusual Powers, but not before killing one of the guards with his mysterious ability.

Crime and Punishment (Japanese: 罪と罰, Russian: Преступление и наказание,) is the ability of Fyodor. It has yet to be explained how it exactly works, but it's seen working by touching another person, immediately causing death, seemingly through blood loss as the ability causes a wound to open and shed a large amount of blood. This ability is not limited to skin contact, as seen when he killed a Special Abilities Division guard, who was wearing gloves. Seemingly unique to Fyodor’s ability, when separated from his body, Crime and Punishment did not turn on Fyodor to attack him during the Yokohama Fog Incident, whereas everyone else was attacked by their stray abilities. The ability itself stated that it was the “punishment” for Fyodor’s “crime”, and claimed the two were close acquaintances, eliminating any threat the ability could pose to its wielder. Genius-level Intellect: Fyodor is one of if not the smartest character in the series. He is able to outsmart the two greatest minds of the Armed Detective Agency, Ranpo and Dazai. Fyodor even predicted that the Agency would attempt to find the virus ability user, Pushkin. Because he knew that, he set up traps to force them to fight the Port Mafia. Ranpo even admits that going up against Fyodor is like going up against Dazai. Master Manipulator: Fyodor's most fearsome trait is how crafty and cunning he is, there were times where he let himself get captured to achieve a task. When he was captured by Ace, Fyodor told Karma that his ability allows him to control space and conscious. However, he only told him that because he knew Ace was listening to their conversation. With the false information, Fyodor made Ace think he was using an ability on him and that the only way to leave his "mind trapping ability" was to kill himself while trapped in it to return to the real world, which caused Ace to end his own life.
