Kosuke Yuki, a high school boy from Sapporo who wants to live as inconspicuously as
possible, gets into one problem after another because of his God-given cheat powers.
At the request of the black cat he rescued (actually a cat god in disguise), Kosuke takes part in a divine match between two onmyoji clans, the Mizukami and the Hinoyama.
Struggling to make full use of his newly acquired powers, Kosuke summons... a mysterious little girl with pure-white hair?!
Despite everything, Kosuke is finally able to lead an ordinary high school life. But a new force is creeping up on him from the shadows...
As the young girl comes to live with Kosuke, the Yuki household is livelier than ever!
