Osamu anime
My dream is to commit double suicide with a beautiful woman, so getting kicked to death by you wouldn't make me happy at all.
~ Dazai to Chuuya


Lazy and obsessed with trying to commit suicide, Ozamu Dazai has a mysterious past and unknown intentions that he doesn't reveal unless he wants to. Despite his eccentricities, he's Atsushi's closest friend and mentor in the Armed Detective Agency, but has connections with the very organization that is trying to capture him.

Intelligence: Dazai, despite his laziness and eccentricities, has an incredibly sharp wit and is a master of manipulation. He was able to deduce that Atsushi was the were-tiger all along from only a few sparse details, easily provoked Chuuya into freeing him, and blackmailed him into letting him go scot-free. His time in Port Mafia has also made him a master of interrogation, infiltration, and torture, with Ozaki noting that not one person has failed to spill everything in the face of his methods. He remains a master of hand-to-hand combatant years after leaving the Mafia, easily demolishing entire groups of Mafia lackeys and fighting any other member on Port Mafia with ease in conjunction with his Ability.

Weaknesses: No Longer Human relies on direct contact with the Ability or the Ability user to function, Dazai is generally lazy and refuses to take things seriously in addition to being suicidal.

Notable Attacks/Techniques:


No Longer Human in action

No Longer Human: (人間失格, Ningen Shikkaku) An Ability whose name is derived from the magnum opus of his real life counterpart, Dazai is able to nullify any other Ability with a touch, forcefully reverting Atsushi back to normal and completely nullifying Akutagawa's Rashoumon. Like other Ability users, he has to manually activate this ability, meaning that it won't protect him from an attack he doesn't see coming.
