Hot-headed as he may seem, Chūya isn't impossible to reason with; reasonable when no one is pushing his buttons. His skills and presence signal an inherent threat, but he's reliable enough to be assigned the task of confronting the Armed Detective Agency. He seldom takes people's lives for granted and knows the importance of compromise and rationality. In the past, he struggled greatly with his identity and place in humanity. His ultimate downfall is his intense disdain and hatred for Dazai.
