Dazai is normally a tease, mainly towards Chuuya. He’s fearless when he wants to be yet lazy and dumb most of the time, finding any reason to annoy people. Chuuya is temperamental and hotheaded, with a drop of stubbornness. He’s easily riled up, making him an easy victim to teasing. That doesn’t mean that he isn’t courageous when it comes to a real situation.
