Birthday: November 11th. Male. The head of the underground organization 'Rats in the House of the Dead' and a member of the murderous society 'Decay of the Angel.' He possesses incredible computer hacking skills and an intellect that is extraordinarily brilliant, transcending imagination (IQ at least 200). He wears a white ushanka, has a pale complexion, always speaks politely, and is characterized by a uniquely unsettling smile. Rather than crushing enemies with overwhelming firepower and combat ability like the Guild, he is a figure who utilizes schemes that seem to manipulate human psychology (you might find yourself swayed before you even realize it). According to himself, he has a weak, anemic constitution. People who do not know Dostoevsky's true identity and are deceived by him tend to perceive him as 'some kind Russian.' He seems to be a very skilled actor. His exact height has not been revealed, but he is depicted as slightly shorter than 184cm, appearing to be around 181cm or within a 1-2cm difference. His MBTI is said to be INTJ. His expression itself is sweet, but he is a formidable man.
