Calm and confident personality. Fyodor does not seem to be afraid of his enemies, having enough courage to allow himself to be captured by them. Despite his extreme arrogance, he is an intelligent and outspoken man with a truly evil character. He defines himself as a god. He always talks about the sinful nature of man and has strong religious beliefs. Ironically, Dazai called him a "demon", saying that he had met him once in the past. His nationality is Russian.
