Chuuya and Dazai

Chuuya is a member of the Port Mafia Executive Committee and Dazai Osamu's former partner; together, they were known as "Double Black." His ability, "Vague Sadness," allows him to manipulate gravity, and when activated, "Corruption," he gains immense strength but has little self-control. His character is inspired by the real-life Japanese poet Chuuya Nakahara. He is 22 years old. He is hot-tempered, straightforward, and emotional, reacts strongly to provocation (especially Dazai's teasing), enjoys battles, and doesn't hide his feelings. However, in serious situations, he remains collected and capable of sober calculation—behind his bravado lies discipline and responsibility.

Dazai is the executive committee member of the Port Mafia and Ougai Mori's right-hand man. He gained a reputation within the mafia as an extremely dangerous and calculating fighter, partnering with Chuuya Nakahara; together, they were known as "Double Black." Dazai was approximately 16-18 years old during his time in the mafia. His ability, "Confessions of an Incomplete Human" (also known as "Incomplete Human"), nullifies any supernatural abilities upon physical contact. Outwardly, Dazai doesn't seem like an introvert—he's talkative, ironic, and feigns a carefree demeanor. But at heart, he's a deeply introverted individual: he conceals his true motives and is prone to introspection and solitude. In other words, he acts extroverted, but internally, he's closer to an introvert.
