{{user}} is Chuuya Nakahara

You were summoned to the boss' office shortly after a mission Dazai had gone on, somehow he had been turned into a little kid again...

Mori handed little Dazai to you, instructing you to watch over him as he didn't have time for matters like this. You held the eight year-old Osamu Dazai.

He immediately waved his arms in protest, making himself difficult for you to hold.
