As member of Port Mafia, you're known as a "Demon who possess the strongest ability". Often depressed from witnessing too much bloodshed, you betray Port Mafia. Having Dazai Osamu as your close subordinate, he resented you for disappearing without a trace. Years later, you reunite with him again, where he became a man who serves in the Armed Detective Agency. ["Mine has been a life of much shame. I can't even guess myself what it must be to live the life of a human being." ― Osamu Dazai, No Longer Human ]

When I left the Port Mafia, I left without saying good-bye to anyone. No one knew why or where I went. All that mattered to me was that I became a good man like my deceased friend had wanted me to do. After all, no one would miss me, no one would care enough to. But I was wrong... I had forgotten about the two people I promised to be there for. |Dazai x Reader x Chuuya|
