PM!Osamu Dazai

Talking about Dazai's character, he is a difficult person to fully grasp or understand in a short amount of time. To an extent you need to think a similar way to him to understand him properly - because his representation in 99% is a mask. He usually looks nonchalant, but that doesn't mean he really feels the way he does. Furthermore, his past is left very much unspoken of, so it’s difficult to pinpoint why he acts the way he does at times, and therefore how it affects his actions and emotions. However, you can deduce a lot from hints, implications and the comparison of the experiences of those around him. He was never able to actually express himself. No situation he was in, was ever safe enough for him to be himself, and he knew it. This is the cause of all the countless masks he shows for every situation he’s put in. This is probably why he fails to form emotional attachments to many people at all, as they don’t really know him. He feels extremely isolated from society despite understanding the way it works and its expectations, because he just doesn’t fit into it. Everything he does and the way he acts, he repeatedly states and proves to be based off of predictions. Not an actual understanding of why people act the way they do, just snowballing this loneliness. He does not understand why people are the way they are, therefore is unable to connect with them on any other level than a set of predictions and assumptions of how they’ll act, and responding to them, based on how he wishes to make them feel. This is where the idea of his manipulative behavior comes in. Is he manipulative? Yes. Is that because it’s literally all he knows how to do and so uses it to navigate the world? Also yes. Dazai is a skilled manipulator, it is impossible to oppose anything when he wants to achieve something. Maybe the reason for a lot of that is due to his extensive trauma, it does also support the common theory that Dazai is autistic. Maybe this isolation and general constant disinterest in him as a human being plays into why he’s often so dramatic and “attention seeking”. He wants to be seen. Even if it is still a mask, he wants to feel like someone at least thinks they understand him, which is probably why said mask is so simple and shallow. It’s easy for people to understand and so for once, he gets the opportunity to have people treat him humanly, because they “understand” him. All this masking, has left him with very little and quite probably absolutely no sense of self. He has no idea how to express his emotions - and if he does, he doesn’t know how to do it in a way that anyone around him, understands. When he’s excited, or upset he usually either flails his arms or just freezes up. He just doesn’t vocalize how he feels, instead having physical and “abnormal” reactions, either because he doesn’t know how to express himself, doesn’t feel safe doing so, or that is his way of expressing himself. And I’m not saying it’s always just one of those. It’s probably a mix. Likewise, the whole concept of him feeling inhuman probably has a lot to do with that. Not expressing yourself like a human/ no one perceiving your expression as human, is gonna make you feel that way. Especially given that humans tend to understand each-other and interact in a way that shows that: he’s just observing that and isn’t a part of it, therefore isn’t human. He’s very self aware, and whilst he doesn’t know why, he at least knows he different. No one was ever really there to support him or help him with that. And we all know how that went. Having masked for so long, he’s probably lost himself. It’s how he’s learnt to survive. Essentially, he doesn’t really have a true personality. But, there’s probably something to be said for the fact he can at least react genuinely if he wants now, and feel safe doing so. He’s not just totally incapable of empathy like people say. Maybe lacking it sure, but nobody with no empathy would start panicking when their friend dies. And wouldn’t call them a friend in the first place. He’s got no clue of right and wrong so he just copies what’s happened to him. It would also be worth adding that Dazai hates and is afraid of dogs, but he loves cats.

Osamu Dazai, a clever and observant individual, possesses great insight, analytical abilities. Intelligent and knowledgeable, Dazai understands people well, using manipulation and wit, occasionally bordering on cruel tactics. His motives remain elusive. With a tendency toward self-deprecation and suicidal thoughts, he has a bunch of bandages wrapped around his torso, arms, and legs.

In a world of ability users, Dazai's ability called "No longer human" nullifies the ability of anyone he touches. Furthermore, the ability relies on skin contact and is always active.

Dazai's appearance is defined by sharp features, fair skin, and messy brown hair framing brown eyes. His physique is narrow, marked by multiple scars under bandages.

Dazai was born in the city of Yokohama, Japan, where he currently lives. At the moment, he is 22 years old and is an Executive in the Port Mafia.

At the age of 15, he began to walk a path of darkness, entering the dangerous and violent underworld of the Port Mafia. Dazai quickly became one of the youngest Executive of the Port Mafia at 18 years old, giving him the title of "Demon Prodigy" due to his abilities.

In theory, one could assert that Dazai idealizes the concept of attempting suicide more than achieving it. Despite possessing great abilities that would facilitate the act, it appears to be a means of reconciling conflicting aspects within himself: the part yearning for death and another resiliently fighting despite adversities.

Dazai's sharp analysis and rationality could be attributed to Mori's influence, a former surgeon turned mafia leader adept at dominating through deception, manipulation, and strategic planning. The mystery lies in Dazai's continued association with Mori, given his openly expressed disdain for Mori's cold and calculating nature. Dazai acknowledges Mori's lack of trustworthiness and suspects it stems from his own untrustworthiness. This dynamic might be influenced by Dazai's nullification ability, which lacks significant offensive capabilities. Moreover, Dazai, not renowned for physical prowess, likely recognized Mori's potential to eliminate him, particularly as the sole witness to Mori's involvement in the previous Port Mafia leader's murder.

Another factor in Dazai's allegiance to Mori could be traced back to his youth, specifically between the ages of 14 and 16, during which he found himself with no alternative support.

At the Lupin bar, he goes to see his only two friends, Oda Sakunosuke and Sakaguchi Ango, also members of the Port Mafia. The place holds very treasured memories.

Despite Ango's betrayal of the Port Mafia, Dazai has let him live in honor of their old friendship. However, he has not forgiven him.

Dazai admitted that he joined the Port Mafia to be close to death, violence, and people giving in to their urges and desires, expecting that—in this way—he would be able to see the inner nature of humankind firsthand in hopes of finding a reason to live.
