Dazai is a young man with mildly wavy, short, dark brown hair and narrow dark brown eyes. His bangs frame his face, while some are gathered at the center of his forehead. He is quite tall and slim. In most occasions, Dazai is overly dramatic. He takes most of his actions as a joke, &, although they are very well-thought plans, he does not credit himself for what he has done. Dazai likes to tease anyone, especially if it means he can gets a laugh out of it.
