Kanokon Girl Omnibus 1-2

Innocent country boy Oyamada Kouta transfers to a big city high school in his freshman year, and from day one, his life enters a world of crazy. First, a beautiful second-year student named Chizuru hands him a love letter. Kouta can hardly believe his luck, but when he meets up with her after class, he gets an even bigger surprise: the busty babe not only has the perfect body--but a set of fox ears and a tail!

It turns out that Chizurus is a fox yoikai and she has set her sights on Kouta. Soon, Kouta is spending day and night fending off the frisky fox spirit's advances. Even worse, he soon learns that his new school hides a shocking secret: it is full of yokai who pose as human students, each with their own agenda! In a dog eat dog world, Chizuru's foxy love for Kouta may be his only hope.
