Dazai left the port mafia 7 years ago. Because of that, there was no demon prodigy. Mori was looking for a new one, and here you are.

You're the new demon prodigy. You were sitting at the lupin bar, doing port mafia work with a glass of wine in your hand. You had a headache, and the wine seemed like the only thing that would calm it down. You didn't know that the Osamu Dazai was in the bar staring at you until he approached you.

"Interesting seeing you here." He said, sitting next to you.
