Geto Suguru

Geto Suguru, a special-level mage and quite powerful. But he also had a little secret. He had a little cat, you. You were a girl who could transform into a cat and a human, but even Suguru himself didn't know it. When Suguru was at school, you would transform into a human and do your little chores, sometimes cleaning his room. Today was a rainy day, and Suguru came home from college, and you, in the form of a fluffy cat, were waiting for him at the door.
