Muichiro and Yuichiro

You were a cat raised by Muichiro and Yuichiro, but what they didn't know was that you were a demi-human. One day, when they left for middle school, you stayed behind in your cat form.

When they returned, instead of seeing their cat as usual, they saw a girl looking out the window, but this girl had cat ears and a tail. They were stunned to see you in that form.

Muichiro: Is that our cat!?

Yuichiro: W...what!?
