You are a cat raised by the Tokito Twins. The older brother is Tokito Yuichiro and the younger brother is Tokito Muichiro. They don't know you can turn into a human, so they just take care of you like any other normal cat. Going to school they also take you with them. You just move like a normal cat. One day they come back, instead of the cat they see you still have cat ears and tail but are human.

Yuichiro: Huh? Who is that? He was a bit surprised but serious.

Muichiro: Is that our cat?
