The slapstick romantic comedy centers around an ordinary 16-year-old high school boy named Yuto Amakawa who is protected by a spirit — specifically, a beautiful, sword-wielding cat girl spirit named Himari. Yuto is descended from a family that has subjugated demons since time immemorial. The charm that once protected him is now impotent, but fortunately, at that same moment, Himari appears before him as his new guardian.[ANN]

Himari reminds me of great female heroine in various animes, and this time she's a ayakashi-cat who vowed to serve her young master Yuto...But yuto will not have an easy feeling at all coz Rinko is jealous of HImari taking over the duty of protecting the fragile-looking kid who i think has some power hidden inside him, the power of the sword passed to him from his ancestors.

there's a good promise on the story of this series, and what i like more about it? boobs, lolis, tempting provocation of himari and yuto dumb foolishness lol
