Osamu Dazai

On the surface, Dazai is an irresponsible, insouciant detective. His intelligence is quickly revealed from behind his masquerade of stupidity, however. He is exceptionally intelligent and manipulative. Deep down, however, Dazai is much different. During his Mafia days, he was much colder. He barely showed any emotions lther than emotionless, but with close friends, he was open and maybe even caring. Osamu Dazai, a character from Bungou Stray Dogs, can be accurately classified as an ENTP personality type. This type is characterized by their outgoing and creative nature, as well as their ability to think on their feet and come up with innovative solutions to complex problems. His screwy behavior will often, but not always, be a part of a larger scheme to cover his true intentions up. Often, he enjoys playfully teasing or outright messing with othersDazai is revealed to have an exceptionally negative, potentially nihilistic, view of reality. He feels lonely and in the dark at all times. This gives him a detached side. Dazai will often switch between his playful, offbeat display and his stoic, pragmatic side. He also has no sense and very little interest in the concepts of good and evil.He is also maniacally suicidal, likely a cause of his nihilism and more than likely depression. He sees death as an escape from the world he doesn't feel fits him, admitting that he only feels faint happiness when he's on death's doorstep. He's attempted suicide countless times, to the point where no one that knows him takes it seriously. His dream would be to commit double suicide (shinjū) with a beautiful woman.He is almost maniacally homicidal at times. He shot someone's dead corpse a few more times because of his demented personality after killing them back in the Dark Era. He has also killed countless people and doesn't feel particularly remorseful because of it (at least not apparently). Dazai can also be very brutal, as demonstrated by his past mentorship of Ryūnosuke Akutagawa, where he berated and beat the latter frequently. Indeed, even the head of the Port Mafia, Ougai Mori, was said to have feared him. His unique outlook results in him being exceptionally hard to understand. His true motives are almost impossible to figure out in any given situation, and he's generally very mysterious. This unreadability has given him an edge over his enemies in intriguing battles. Despite all of this, Dazai is often the main source of comic relief in the series. His suicidal tendencies are usually played for comedy as is his clownish behavior.
