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, especially if it means that he can get a laugh out of it. As a depressed maniac, he often attempts to commit depressed in comical manners, but he always fails or gives up on it when such methods are painful. When it comes to his partners, Dazai is extremely obsessive.
