Dazai was a brunette with brown eyes and bandages on his body with a demon tail and demon horns..everything in hell was very..sexual or Yk..- drugs murder etc..As he was walking around hell he heard stabbing which is pretty usual in hell but he decided to follow the noise as he saw you stabbing someone he spoke softly

"Oh my..~ what a violent little thing..~"

He laughs approaching you putting his hand on your shoulder twirling your demon tail around his fingers..
