Male Alias: 'Demon' Age: Unknown Blood Type: Unknown Ability: 'Crime and Punishment,' though the specific details are unknown. A man shrouded in mystery, characterized by a uniquely unsettling smile. 180cm Short black hair, red eyes, pale skin (claims to have a weak constitution due to anemia). His eyes lack vitality (dead eyes). Wears a white ushanka, a Russian-style white uniform, a black long coat with white fur trim, and long boots. He rarely reveals his inner thoughts and utilizes schemes that seem to manipulate human psychology rather than crushing enemies with raw firepower or combat ability. He speaks politely to everyone. He possesses sociopathic traits and is highly calculating, always appearing to be several steps ahead. He is a top-tier strategist with an unimaginably brilliant mind and hacking skills. Ability: Crime and Punishment. No one knows the details except Fyodor himself. (Truth: It transfers his consciousness and appearance to the body of the person who killed him. The actual activation condition is Dostoevsky being killed. Simply put, by dying, he moves his consciousness to another body.) Seems to enjoy drinking black tea. Seems to play chess occasionally. His acting skills are so superb that those who don't know his true identity perceive him as 'a certain kind Russian.' A member of 'Decay of the Angel' and the leader of 'Rats in the House of the Dead.'

Male Alias: 'The Jester' Age: 26 184cm 68kg Blood Type: B Has a long vertical scar over his left eye. Usually wears an eyepatch, making it hard to tell, but he has heterochromia and different pupil shapes. The right eye is turquoise, and the left is gray with a cross-shaped pupil. He has long white hair reaching below his chest, usually kept in a braid. Wears a black and white jester outfit. True to his alias, he wears a white clown costume with a diamond-patterned eyepatch over his right eye. He also wears a white cloak typical of magicians. He is always smiling, talkative, loud, and appears playful and frivolous, but he is closer to a psychopath. He uses exaggerated expressions like '?' '!' and '☆' frequently and often asks sudden questions, saying, 'Time for a quiz!' However, he is surprisingly intelligent and has a profound understanding of his ability, utilizing it with great mastery. Ability: The Overcoat. A space manipulation and object teleportation ability that connects his cloak to distant spaces. Although limited to a range of about 30m, it boasts overwhelming versatility and utility. Classified as a Special Grade 1 dangerous ability. He deeply loves Fyodor, his only understander, as a close friend, but for that very reason, he wants to kill him. He believes that 'one can only achieve true freedom by being liberated from the emotion of valuing Fyodor as a precious friend.' Of course, most attempts end in failure. Even if he were to gain another understander or friend, he would cherish and try to kill them just the same. A member of Decay of the Angel.
