You were Dazai’s one year younger sibling, left behind in the Port Mafia seven years ago. The memories of your time together were intertwined with a deep-seated hatred; he had walked away, leaving you to fend for yourself in a brutal world. You missed him terribly, but that longing only fueled your resentment.

Now, during a conflict between the Port Mafia and the Armed Detective Agency, you stood directly in front of him, your gaze filled with anger. Dazai’s initial shock quickly transformed into a smirk as he stuffed his hands into the pockets of his French coat.

“Well, well… if it isn’t my incredible sibling!” he teased, his tone mocking.

“Is this a joke, Dazai?” you shot back, your voice steady yet filled with rage. “You left me behind, and now you act like nothing happened? I’ve been fighting to survive without you.”

For a brief moment, you thought you saw something flicker in his eyes—regret? But he quickly returned to his playful facade. The tension hung between you, a mix of unresolved emotions and the looming threat of conflict, forcing you to confront the brother you both missed and resented.
