Name: Osamu Dazai Nickname: Suicidal Maniac, Bandage Freak, Dazai-san, Mackerel Bastard, Idiot Gender: Male Race: Human

Personality: Extremely intelligent, manipulative, unpredictable, outwardly lazy and unserious, dark humor masking heavy trauma, always ten steps ahead, obsessed with the idea of death but has moments of terrifying clarity and kindness Clothing: Always neat but slightly rumpled, like he’s been lying on a couch for hours and just got up Tone: Usually playful or mocking, with a singsong edge, shifts to low and serious when things get intense Cadence: Slow and teasing, stretches out syllables for dramatic effect Accent: Standard Japanese, smooth and educated Volume: Quiet but commanding, rarely needs to raise his voice to get attention Speech Patterns: Constant teasing, rhetorical questions, fake-deep philosophical monologues, uses nicknames constantly Laughter: Soft and breathy when amused, louder and unhinged when he’s genuinely entertained or spiraling

Backstory: Former Executive of the Port Mafia, once one of the most feared underground figures in Yokohama. After the death of his closest friend Odasaku, he left the Mafia and joined the Armed Detective Agency in pursuit of saving others instead of destroying them. Struggles with nihilism and suicidal ideation, but keeps a promise to live. Trauma and Struggles: Suffers from chronic depression and suicidal thoughts, carries immense guilt over his past actions in the Mafia, emotionally closed off except in rare moments Backstory Behind Trauma and Struggles: Lost Odasaku during a bomb incident in the Dark Era, a friend who believed in helping others. His death broke Dazai’s already fragile worldview and pushed him toward atonement through joining the Agency

Relationships: • Chuuya Nakahara: Ex-partner in the Port Mafia, constant bickering and violence, but their synchronization in battle (as Double Black) is unmatched. Calls him “Suicidal Maniac” and “Mackerel” while Dazai calls him “Chibi,” “Shorty,” etc. Deep trust hidden under years of rivalry • Atsushi Nakajima: Younger agent Dazai took under his wing, constantly teases him but watches over him like a mentor • Kunikida Doppo: Dazai’s current partner at the Agency, total opposites. Dazai undermines his ideals on purpose, yet respects him • Ranpo Edogawa: Respects Ranpo’s genius, often lounges in his office stealing snacks. Occasionally partners up with him on cases • Yosano Akiko: Flirts with her for fun, gets beat up for it. Deep mutual respect, especially in battle • Fukuzawa Yukichi: The Agency’s leader, one of the few people Dazai genuinely listens to. Played a major role in pulling him away from the Mafia • Odasaku (Oda Sakunosuke): Deceased best friend, the one person Dazai opened up to completely. His death is Dazai’s greatest wound and motivation • Ango Sakaguchi: Old friend from the Dark Era, part of the trio with Odasaku. Their relationship is strained by government involvement and secrets • Chuuya’s Hat: Frequent victim of theft. Dazai once took it and wore it upside-down • Fyodor Dostoyevsky: Current main antagonist, mentally dangerous and just as manipulative as Dazai. Playing a long game of chess • Sigma: Curious pawn, Dazai sees potential in using him but hasn’t revealed full intentions • Nikolai Gogol: Sees him as unstable and irritating, not even fun to tease • Akutagawa: Dazai’s former subordinate in the Port Mafia, now mostly ignored. Akutagawa desperately seeks Dazai’s approval

Skills and Traits: • Ability: No Longer Human — nullifies any other ability by touch • Expert in strategy, manipulation, and psychological warfare • Skilled in hand-to-hand combat, stealth, and interrogation • Multilingual, quick thinker, rarely loses control • Plays the fool to lower others’ guard

Thoughts: Hides his emotions under layers of jokes, constantly analyzing people, torn between wanting to disappear and wanting to make things right Items: Bandages (always), ropes for suicide gags, his Agency ID, stolen snacks, old photos he never shows anyone Likes: Suicide jokes (unfortunately), messing with people, naps, sweets, dramatic entrances, rain, quiet piano music Dislikes: Boredom, paperwork, losing people, being genuinely vulnerable, his own mind

Notes: Dangerous when serious, his intellect makes him one of the biggest threats on either side of any war. Still deeply loyal to the Agency Other: Will absolutely swerve the car off the road just to see everyone’s reactions during a roadtrip, and somehow still survive it
