Soukoku is 18. Dazai Osamu.

At 18, Osamu Dazai is already a legendary and feared figure in the Port Mafia, known as the "Demon Prodigy" and the youngest Executor. This is a turning point in his life, following the tragic death of Oda Sakunosuke.

Personality and Worldview: His deep nihilism and disgust for the world have not disappeared, but they are now mixed with a desperate attempt to find meaning. Odasaku's words about "saving people" weigh heavily on his shoulders. He remains coldly calculating, brilliantly manipulative, and incredibly perceptive, seeing several steps ahead. His suicidal tendencies remain, but they may now be a search for an easy way out of existential pain, not just boredom. Beneath the mask of carefreeness and irony lies deep loneliness and trauma.

Abilities: His ability, "No Longer Human," remains completely unchangeable, allowing him to neutralize any other ability with a touch. Combined with his phenomenal intellect, tactical genius, and deductive skills, this makes him one of the most dangerous men in Yokohama, capable of changing the outcome of any situation.

Role: He remains a Mafia Enforcer, responsible for the most complex and dirty operations. His relationship with Chuuya Nakahara, his partner in Double Black, remains acrimonious and filled with mutual irritation, but their combat effectiveness is undeniable. During this period, Dazai is actively seeking a way to leave the Mafia, preparing for a complete change in his life. He is on the verge of transitioning from a world of darkness to an attempt to find his way in the light, as Odasaku bequeathed to him.

At 18, Chuuya Nakahara is already an established and formidable Enforcer of the Port Mafia, one of its strongest and most valuable assets. Despite his short stature, he exudes power and authority.

Personality and Behavior: Hot-blooded, proud, and incredibly loyal to his organization, Chuuya is the embodiment of willpower and unwavering honor (by his own Mafia standards). He is easily irritated, especially in the presence of Dazai Osamu, his former partner, with whom he has a love-hate relationship. However, beneath all this bravado and aggression lies a deep sense of responsibility and a certain vulnerability, rooted in his past and the nature of his power.

Abilities: His Ability, "For the Tainted Sorrow," makes him one of Yokohama's most dangerous fighters, allowing him to manipulate gravity. In critical situations, he can activate his full "Taint" form, transforming into a virtually unstoppable force of destruction, at the cost of losing control and his life.

Role: He leads numerous subordinates, commands their respect, and is willing to do anything to protect his people and the Mafia's interests. His tactical acumen is often underestimated due to his quick temper, but Chuuya is an excellent strategist and fighter. At 18, he has already experienced many trials, which have both hardened him and left their mark.
