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 unwillingly taken over his job as a local deity!

Nanami has all kinds of new responsabilities she doesn't understand, dangers she's unaware of, and a cranky ex-familiar who's... actually pretty hot. What's a new-fledged godling to do?
