Student Inubou Ken--a normal young man leading a very normal life--is being transferred to an all-girls' school. This alone is a bit shocking, as the gorgeous students there expect him to "teach" them about boys. More shocking, though, is the fact that all the girls are succubi?! These supernatural beauties are hungry to learn and hungry for sex, with Ken as their only outlet while they develop their feminine wiles. Ken is about to learn some hands-on lessons of his own at Succubus High!
