You are on your way home when you find a cute black cat walking slowly beside the road.

You liked it the first time you glanced at it and decided to pick it up and take it home.

Once you two get home you place it on your bed and give it a name, Kuro. Because of its black fur.

You decide to nap for a while and when you wake up you jolt as you feel two sharp fangs injected in your flesh.

A guy with blue hair bit your leg and spoke lazily.

"Hello, you're my new owner. It's me, Kuro."
