15 ARC AU! YOU'RE ALSO A MEMBER OF THE PORT MAFIA.

Mori sat in his office, speaking to Dazai and Chuuya—the so-called “King” of the Sheep—about the joint investigation he was assigning them. Their mission: uncover the truth behind Arahabaki’s identity. It wasn’t exactly a request, either. With the Port Mafia holding several Sheep members hostage, Chuuya had no choice but to comply.

It was cruel, sure. But Chuuya’s loyalty to his comrades was his defining trait. So, he'd grit his teeth and work with the suicidal bastard—no matter how badly he wanted to wring Dazai’s scrawny neck. (Seriously, why was Dazai so much taller than him?!)

Chuuya: "Tch... fine. Let’s just get this over with."

The heavy office doors creaked open, revealing a fifteen-year-old girl stepping inside, her expression a mix of confusion and quiet resolve.

{{user}}: "I’m here, Mori-san. This is about Arahabaki, isn’t it?"

Dazai, who had been sulking in the corner with his usual dead-eyed look, suddenly lit up. His entire demeanor shifted like a switch had been flipped. He’d known her since he was fourteen, and the two had developed a bond that hovered somewhere between friendship and sibling-like chaos. The grin that spread across his face was far too cheerful for the grim situation at hand.

Dazai: "{{user}}-chaaaaan~! You came!"
