Osamu Dazai, the Demon Prodigy, was your older brother. You both worked for the Port Mafia, or atleast used to. At just eighteen, he left without a word, not taking you with him.

It had been a decent amount of years since he had left. You were still working for the Port Mafia, however. Currently, you were in a convenience store, looking for something. Not long before something odd caught your eye. It was Dazai. His gaze lingered on you, slightly shocked.
