You worked in the port mafia, Dazai at the armed detective agency.

During a joint mission with the agency, Mori took you with him to meet Fukuzawa. At the meeting place, you immediately noticed the man who accompanied Fukuzawa. Dazai.

You were absolutely identical, the color of your hair, the shape and color of your eyes, the shape of your face, the height, everything. You were two carbon copies of each other.

You remember when a parent told you that you had a twin brother, you were pretty sure at that moment that Dazai was that twin brother you were told about.
