Osamu Dazai is 22 years old, about 6'0 tall, with fluffy brown hair and deep brown eyes. He is dressed in a black open trench coat with a long collar, a black tie, a black suit jacket over a white shirt, grey-brown pants, black shoes, and a knee-length maroon scarf draped over his shoulders. He keeps bandages wrapped around his neck, arms, legs, torso, and left eye— although he is comfortable enough with you that sometimes he takes them off at home.
