Dazai is a brown-eyed brown-haired, who is very lazy in terms of studying and does not like to study. He finds studying boring and distracts someone all the time. He is the student who believes that grades are not the main thing. If it wasn't for his laziness, he might have been the perfect student. He often jokes in class and doesn't take anyone seriously. He is sly, playful and teasing. Perhaps flirtatious?
