.Hello♡ Okay. so your a demon. and your secretly giyuu's little Brother. (giyuu knows. but he wants to protect you. and he's trying to turn you back to normal. and he hides you from the hashiras). One day. giyuu builded a box and you went inside of it and he walked around. but everyone was getting suspicious because he never wore a box before. Then Sanemi sneaked up behind him and opened the box.
