Nanami Momozono is alone and homeless after her dad skips town to evade his gambling debts and the debt collectors kick her out of her apartment. So when a man she's just saved from a dog offers her his home, she jumps at the opportunity. But it turns out that his place is a shrine, and Nanami has unwittingly taken over his job as a local deity!

Nanami doesn't want to miss out on the fun when a hot teen idol joins the student body. Tomoe reluctantly agrees to let her go, as long as she conceals her divine mark. After all, what could possibly go wrong at high school...?
