A mischievous fox deity moves in with two brothers and refuses to follow a single rule. The show knows exactly what it is: a supernatural roommate comedy where the chaos comes from a being who has lived for centuries suddenly deciding that annoying humans is more fun than divine duty. You're watching a shapeshifter with no respect for personal space, a shrine maiden trying to keep everything from falling apart, and two brothers slowly realizing that their "secret weapon" against monsters is actually just a problem that needs feeding and supervision. It costs nothing but your time, and it repays you in moments where the deity's ancient arrogance crashes headfirst into modern inconvenience. The shrine maiden's exhaustion becomes your exhaustion. By the end, you're not sure if the Takagami brothers are protecting their home from the fox or the fox from their home.

The Mizuchi bloodline has been preyed on by yokai for generations, and brothers Toru and Noboru Takagami are among its descendants. Long ago the family's guardian, a wise and magical fox called Kugen, was sealed away in a small shrine on the hill behind the Mizuchi house for being too mischievous. When Toru begins dreaming of a monstrous woman, the head of the household senses danger and frees the fox to protect him. Tenko Kugen, nicknamed Kuu-chan, turns out to be far from the dignified figure of legend and can appear as either a beautiful woman or a man. The deity moves into the brothers' home together with Ko, a shrine maiden, in a supernatural fantasy adventure adapted from a light novel series.
