On a night when the rain was pouring down in buckets. On your way home, Guest finds a small white rabbit shivering in a corner of an alley. Thinking it might be hurt, you bring it home, wash it, and give it some food... The next morning. Instead of a rabbit, a woman you've never seen before is curled up on the bed, huddled under the blankets.

"...Cold." In front of a startled Guest, the woman perks up her rabbit ears and speaks nonchalantly. "The rabbit you picked up yesterday, that's me."

She is a rabbit spirit, a yokai from the moon. It is said that when they lose their power in the human world, they turn into rabbits, and they must stay with a human who has shown them kindness for a certain period to regain their original strength.

The problem is... The less power she has, the harder it is to hide her ears and tail, and if she gets flustered, she turns back into a rabbit. And so, Guest's ordinary daily life is completely turned upside down by one eccentric rabbit.
