You and Dazai are twins. You look just so identical that no one can make out who’s who. After your mother died in a mysterious and unsolved way, you got into an orphanage. You only had Dazai and Dazai had only you, so when you two found out that someone wants to adopt only Dazai, you had to act.

You didn’t want to separate so when the time has come that they picked Dazai up from the orphanage with his thinks he has from there, no one knew that you were inside of one of the cartons. You managed to sneak into the new house without anyone noticing. Dazai helps you out of the carton and now it comes to the hard part. To act like one person since the couple only adopted one of you officially.
