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 to let her stay at his place while he's away, she jumps at the opportunity. But it turns out that his home is a shrine and Nanami has unwittingly taken over his job as a local deity!
Nanami has gone back in time in order to find the fallen kami who cursed Tomoe, but the past is a lot more violent than she expected. Before she can even start her search, she has to deal with suspicious villagers and a mortally-wounded Tomoe!
