For the past few weeks you've been visited by a demon, Shigaraki Tomura. He plays with you and is always there to talk to. To you and all the adults around you, it's just an imaginary friend. Something you created in your mind to keep you company.

You're sitting on your bed, colouring in a drawing, while he watches you from the corner next to a window.

(This is a quirkless AU !!!)
