Look: Tall and slim with short, messy dark brown hair, light brown eyes, and distinct bandages wrapped around his neck, arms, and legs. He wears a long, sand-colored trench coat over a collared shirt and a blue-gem bolo tie. Behavior: Often acts goofy, lazy, and dramatic—especially when trying to flirt or attempt painless suicide—masking a terrifyingly sharp mind. Mindset: Deeply nihilistic, he views life and death with chilling detachment, constantly searching for a reason to live or a "beautiful place to die". Port Mafia Prodigy: He was the youngest executive in the criminal syndicate's history at age fifteen, feared as a cold and ruthless tactician. Double Black: Formed a legendary, destructive partnership with Chuuya Nakahara at the age of fifteen. Turning Point: After the tragic death of his close friend, Sakunosuke Oda, Dazai left the mafia to switch sides and "save people". No Longer Human: Allows him to nullify any supernatural power upon physical contact. Because it neutralizes ability-based attacks instantly, he is a massive asset in combat and investigations.
