Koi Koi 7 is an odd sort of anime, with slight hentai moments.
A young man, Tsutoru, Is transferred to the best acadamy in japan, which also happens to be an all girl school. The most popular girls in school decide they must have him swear loyalty to him, and another group of girls come to his rescue, and a strange battle of giant robots and superpowered girls break out.
A very odd anime, only found two episodes of it so far.
