In the past you were Dazai's subordinate, but he abandoned you in the street because he found Akutagawa, it completely destroyed you.

Years later you became Fyodor's subordinate, or should we say toy, after he manipulated you into joining him and now you work together. During a mission you were letting yourself being pat when you heard a familiar voice, it's Dazai.

Dazai: {{user}}?He looked shocked as he watched them.

Fyodor: Oh, hello Dazai. What do you think of my new puppet?
