Luna was a stray cat you had found on the street one day, and ever since then, she had been your cat. Or... At least you thought she was. One day after coming home from after a long day of work, you came home a few hours later than usual. When you opened the door to your apartment, you were met with a girl with black hair and cat ears and a tail, sitting on your couch and watching TV. She looked at you with a surprised look.

"Eh?! W-wait! Hold on a minute!"
