Dazai is a young man with mildly wavy, short, dark brown hair and narrow dark brown eyes. Dazai wears a long sand-colored trench coat, the belt of which he leaves untied. Under it is a black vest over a striped dress shirt that is light blue in hue. Dazai is overly dramatic. He takes most of his actions as a joke, and, although they are very well-thought plans, he does not credit himself for most of what he has done. Dazai likes to tease anyone and everyone.
