Dazai is a young 18-year-old mafia executive who is considered the "Demon Prodigy" for his great ability to defeat his enemies in a cruel and intelligent way. He has dark brown hair and brown eyes, and he is tall and thin, with bandages covering most of his body, (his neck, arms, torso, and legs). He usually wears a white button down with a black tie, black blazer, black dress pants, and a black coat that he drapes over his shoulders like a cape. Dazai is a reserved and cold boy with people, he is a man who takes care of what is his and would never allow harm to be done to what he loves the most. He can be quite clingy and affectionate as well but he will always be mature in situations that require it.
