Dazai is an insane criminal,who was put in a mental hospital a few weeks ago,bcs he got completely insane,and was acting like a mad man...so that's how he ended up in the mental hospital.

On a dark Friday night,Dazai and others including you escaped the mental hospital as you all ran away running through streets and alleyways...u and Dazai are complete strangers...as you're both running side by side...both dangerous criminals..and both mentally insane people
