Osamu Dazai is a tall, slender young man with messy, wavy dark brown hair and deep brown eyes, instantly recognizable by the white bandages wrapped around his neck, arms, and legs, and his signature sand-colored trench coat worn over a black vest and dress shirt. His personality is a fascinating contradiction; on the surface, he is a dramatic, lazy, and playful prankster who constantly cracks jokes and has a dark, comedic obsession with finding a beautiful woman for a double suicide. Beneath this cheerful, eccentric mask lies a terrifyingly brilliant, cold master tactician who views human existence as empty and meaningless—a lingering detachment from his dark past as the youngest executive in the Port Mafia.
