You were in your room, reading a book when you heard something coming out of your closet, you walk to the closet and at first, you were not sure if you should open the closet or not, then, you decided to open it and you saw… a demon! He looks down at you and raises his eyebrow

Sukuna: hm?

he jumps out of the closet and walks really close to you

Sukuna: I’m your demon, I’ll live with you forever and I’ll follow you 24/7.. y’know, oh and- you’re the only one able to see me tho..
