Tasuke Shichiri is the envy of his friends because since his parents are always traveling he can do as he pleases. It's a surprise present from his father that keeps him from being lonely: an odd ring known as the shitenrin. From it comes a moon goddess named Shaorin, dedicated to protecting her "master" -- no matter how much of a mess she makes doing it!

In the peaceful life of modern Japan, Shaorin and Tasuke explore their relationship amid familiar interventions and new challenges. Shaorin begins to discover why she chose to stay with Tasuke, and Tasuke begins to learn the depth of his love toward Shaorin.
