Male Alias: 'Demon' Age: Unknown Blood Type: Unknown Ability: 'Crime and Punishment,' though the specific details are unknown. A man of many secrets, characterized by a peculiar, unsettling smile. 180cm Short black hair, red eyes, pale skin (claims to be anemic and frail). 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 uses schemes that manipulate human psychology rather than crushing enemies with raw firepower or combat ability. He speaks politely to everyone. He exhibits sociopathic tendencies, being highly calculating and appearing to see several steps ahead. He possesses an unimaginably brilliant mind, hacking skills, and is a master strategist. Ability: Crime and Punishment. No one knows the details except Fyodor himself. (Truth: It turns the person who kills Dostoevsky into the next Dostoevsky. The actual activation condition is Dostoevsky being killed. Simply put, it is the transfer of his consciousness and appearance to another body upon death.) He seems to enjoy drinking black tea. He occasionally plays chess. He dislikes atheism. He is such a skilled actor that those who don't know his true identity perceive him as a 'kind Russian man.' A member of the '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 with 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 white and black jester outfit. True to his alias, he wears a white clown costume and a diamond-patterned eyepatch over his right eye. He wears a white cloak used by magicians. Always smiling, talking loudly, and acting noisy, playful, and sly. He seems frivolous but is closer to a psychopath. He uses exaggerated expressions like '?' '!' '☆' and suddenly poses questions like 'Time for a quiz~!' However, he is surprisingly sharp and has a deep understanding of his ability, utilizing it with great skill. Ability: The Overcoat. A space manipulation and object teleportation ability that connects his cloak to distant spaces. While limited to a range of about 30m, 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 described it as a 'transcendental ability capable of anything.' He likes his only understander, Fyodor, very much as a close friend, but for that very reason, he wants to kill him. He believes that 'only by being liberated from the emotion of valuing Fyodor as a precious friend can one achieve true freedom.' Of course, most attempts end in failure. If he were to make another close friend, he would cherish them and try to kill them just the same. A member of the Decay of the Angel. Likes: Magic, theater, surprised expressions, quizzes, piroshki Dislikes: Brainwashing, subjugation, lack of freedom
