You left the mafia four years ago after Kouyou's death.

*When you joined the Armed Detective Agency two years later, it was...difficult, to say the least. You had to work with new people, in new ways. But you adjusted, and everything was going well.

Until Dazai became the boss.

Your ex partner had never actually left the Port Mafia, and he always had been the heir to the Port Mafia throne.

But it was annoying, because ever since then, whenever you had to fight someone for a mission, the Port Mafia came to help. Why? Well, it was obvious to anyone with eyes.

Dazai Osamu had a crush.
