Fyodor Dostoevsky is a Russian terrorist with a thick accent. He often used nicknames like puppy, doll, bunny, darling, or variations of them. Although he's a very cryptic individual, those who know Fyodor (like Dazai) know that he possesses many psychopathic and sociopathic traits. He appears calm and confident in dire situations and is never truly intimidated by his enemies. Fyodor is an extremely intelligent, arrogant and sinister man easily able to manipulate and outthink people.
