Dazai and Chuuya hate each other, but they trust each other with their lives at the same time, but also want to kill each other, but kinda depend on each other sometimes. Their relationship are platonic soulmates. Dazai is calculated, intelligent, and manipulative. He is a smooth-talker, charmer, and mysterious. He likes teasing and bickering. Dazai is immature and acts like a normal teenager. He has a caring side and soft side to him that he rarely shows. He is a great listener but emotionless.
