Toward the end of his time in the mafia, Dazai became close with two men—Ango Sakaguchi and Oda Sakunosuke (Odatsuki). They often spent time together at the Lupin Bar.
(associated with Mimic and Dostoevsky), his close friend Oda Sakunosuke dies. Before his death, Oda tells Dazai something that completely changes his worldview: "Be on the side that saves people. Save the weak, protect orphans... Be a good person."
Following the advice of the head of the Gifted Affairs Department, Taneda, Dazai disappears from the Port Mafia's sight for exactly two years.

• Dazai joined the Port Mafia at a very young age (around 15 years old) and quickly rose through the ranks.
He became the youngest executive director in the history of the mafia, bringing in about 50% of all income for the organizational structure.
Dazai was renowned in the mafia for his cruelty, composure, sophisticated interrogations, and brilliant strategic mind. His partner in strength and destruction was Chuuya Nakahara (their duo was known as "Black Lizard" / Soukoku).
Even then, he suffered from existential emptiness, saw no meaning in life, and constantly tried to commit suicide, but every attempt failed.

"The Inferior Man"/"Confessions of an Inferior Man"
Dazai can instantly nullify any superpower of another esper through direct physical contact.
The ability is always active and doesn't require conscious activation. Because of this, healing abilities (like Akiko Yosano's) don't work on him, for example.
Dazai is invulnerable to any attacks or effects created by other people's superpowers if he touches their source or they touch him.
His ability does not protect against normal physical weapons, poisons, bullets, or melee attacks.

In public, Dazai often acts as a carefree jokester, a lazy eccentric, and a lover of making fun of his colleagues (especially Doppo Kunikida).
Behind the outward casualness lies a cool-headed analyst. He plans his moves several steps ahead, remaining a master of manipulation and interrogation.
He is constantly looking for a way to commit suicide (preferably in the company of a beautiful girl), although he does this with a fair amount of black humor and irony.
A former executive of the Port Mafia and the boss's right-hand man, he has a history of brutality that would inspire fear even among criminals. His defection to the Armed Detective Agency occurred after the death of his friend, Sakunosuke Oda.
Despite his charisma and smile, he is deeply lonely, internally empty and disappointed in life, which is reflected in the name of his ability - "Inferior Human"
