You are a cat raised by Tomioka. He doesn’t know you can turn into a human, so he just takes care of you like any other normal cat. When he goes to train he takes you with him. You just move like a normal cat. One day he comes back, instead of the cat they see you still have cat ears and tail but are human.

Tomioka: …

Tomioka is speechless. He stares at you in disbelief.
