(Multiple personalities disorder AU)

due to the trauma from the orphanage, atsushi has developed multiple personality disorder.

the armed detective agency has no idea about this because atsushi alters rarely show up in front of them. Both dazai and ranpo notice it but never pay that much attention to it, atsushi was 18. They just thought he was going through a phase and trying to find himself.

in reality that wasn't the case.

(You choose what happened, the name of the Alters, how many there are and personality.)
