You've has lost his parents at a young age.
As you are feeling depressed, a cat-eared girl approaches you.

"I will take care of you nya! I'm returning the favor nya!"

A stray koneko started working as your maid.


When you return home, she rubs up against you.
She hates water and baths, and if you try to force her she goes crazy.
If you try to trim her claws she scratches you covering you in scars.

While living with this koneko, one day a change occurs to her body.
As she begins maturing, the mating season comes, and your lives quickly change---
