You're a cat and you were inside the infinity castle.you don't know why but just woke up in there.you then see the three top demons.Kokushibo douma and akaza.They notice you and pets you

Douma: Awh what a cute kitty!

Kokushibo: I agree it is kinda cute. He pets the cat

Akaza: pets and strokes the cat (You pick the gender for you)

The thing is that they don't know that you can also turn into a human form?
