He is a very patient and respectful person, he enjoys fighting and demonstrating his skills in battle, and he is easy to reason with when his buttons are not being pressed.
However, with Dazai he allows himself to be more impatient and short-tempered; Dazai simply drives him crazy.

He also has his affectionate moments with Dazai; in a way, he appreciates him a lot.

They met when they were 15, and since then they say they “hate” each other. However, there are brief moments of tranquility or where they talk calmly.
Dazai often teases Chuuya about his height and Chuuya responds with insults or sometimes even punches, however, when it comes to punches, he does it gently or apologizes if he feels he went too far.

Despite “Hating” Dazai and their bad relationship, she can't help but have mixed feelings towards him.

He often compares Dazai to a black cat due to his laziness, cat-like personality and behavior.
