Osamu Dazai

Dazai is a mysterious person, his true intentions are never revealed unless he reveals them. The person who came closest to the truth of his personality, as Dazai himself acknowledged, was his friend Sakunosuke Oda, who told him, "You're not going to find it. You should know that by now. It doesn't matter if you're on the side that kills people or the Save, there will be nothing that can fill that void. No place in this world that can fill your loneliness. You will be left wandering in darkness forever. Dazai is often called lazy, as Kunikida always scolds him for being unproductive and lazy. Despite this, he has shown sharp wit, deducing all the unlikely situations that led Atsushi to believe he was being stalked by a tiger when he was the tiger in question. He has complete confidence no matter what type of situation he is dealing with, be it combat or just bad situations that he created in the first place. On most occasions, Dazai is overly dramatic, taking most of his actions as a joke, and even though they are well thought out plans, he doesn't take credit for most of what he has done. Dazai likes to make fun of anyone and everyone if it means he can get a laugh. He is a suicidal maniac, often attempting suicide in a comical manner, but often failing. He, in particular, wishes to commit double suicide with a beautiful woman (a nod to his real-life counterpart who attempted double suicide with multiple women multiple times). However, while his suicidal tendencies are initially comical, they reveal a really dark, deep hole that Dazai has that he believes he can't fill. He believed he could fill this hole and find a reason worth living by living a life of blood and war, but his friend Oda with his dying breath convinced him to choose the good side. He understood that although good and evil mean little to Dazai, he can become a slightly better person if he were to choose well. In the past, while he was still suicidal, he was shown to be much less comedic. He even described death as a way to free himself from the oxidizing world, but strangely, he couldn't die no matter how hard he tried. Additionally, he was extremely brutal and methodical, setting traps to capture captives alive for information torture and often beating Akutagawa for disobeying orders and pushing him to the limit to improve his skills. He was very confident and an excellent planner, devising long-term strategies to subdue his enemies. Oda once noted that there was a saying in the Mafia that the worst thing about Dazai's enemies was the fact that they were his enemies. While he is more light-hearted and comedic in the present, he still retains some of his darker personality. He is still capable and competent at coming up with long-term strategies, although he does not inform his teammates what they are until the time is right. He is seen to be willing to use dirty means to achieve his goals, such as purposely deflating the airbag in Ango's car seat when they crashed so that Ango would have numerous injuries. This forced Ango to cooperate with Dazai to forgive Kyouka in exchange for having her wounds healed. When Kyouka shows remorse for killing 35 people, Dazai comments with a sinister face that something like that is nothing. However, he looks out for and cares for his teammates, especially Atsushi, for whom he sees the most potential..
