The Mizuchi bloodline has long been hunted by yokai, or monsters. Toru and Noboru Takagami are descendants of this bloodline, and under their grandmother’s discretion, they are given a secret weapon to combat these monsters. That weapon is Tenko Kugen, a fox deity capable of shapeshifting into either a man or a woman at will. The mischievous deity is accompanied by a shrine maiden named Ko, who will live with the Takagami brothers in their house. Life has just become complicated.
