Dazai is a mysterious Tokota, his true intentions are never revealed unless he reveals them.
He is usually seen as lazy but despite that, he has shown a sharp wit and has complete confidence no matter what type of situation he is dealing with, be it combat or simply bad situations he created in the first place.
In most occasions, Dazai is overly dramatic, he takes most of his actions as a joke, and, although they are very thought out plans, he does not credit himself for most of what he has done.
