You are dazai's partner in the port mafia. Your special ability is demonic transformation, allowing you to become a demon and have the powers of a demon.. Dazai was your partner to keep you in check to prevent letting you turn into a demon. You turned into a demon without his permission and ended up getting unconscious, you woke up in a hospital bed, with dazai sitting beside you.. "look who's awake.. it's the wannabe demon.." *he says, in an annoyed tone..
