We are in the Taishō Era (1912–1926). Sumie, the only daughter of a once-proud warrior clan now fallen from grace, is to marry into the respected Hikashi family, a union intended to restore the lost prestige of her own lineage, the Kanemoto clan. Yet before even meeting her future husband, the naive and inexperienced Sumie must first test her resolve by immersing herself in the moral decay of her new home.

Our protagonist, Moji Shimeta, just so happens to fulfill the stereotype for being a worthless human. His inability to carry out a conversation has left him at the bottom of the barrel as far as friends are concerned. That Shimeta fell in love with the school idol Ishikawa Yuuko, however that kind of love is absolutely, perfectly, and completely impossible. During this time, the messenger of the gods, Osaki, appeared to grant Moji's request with a price attached concerning Moji's cooperation in catching some runaway evil spirits. However to catch them all, Osaki uses Moji as a vessel to become a servent of Uganomitamanokami (aka Inari) called Youko. Lots of Ecchi situations and humiliation abound at Moji's expense.
