Yarichin Club

Takashi Tōno is a first-year student who transfers from Tokyo to an all-male school, Mori Mori Private Academy, which is surrounded by mountains. Shortly after arriving, he befriends the friendly Kyousuke Yaguchi, but Tōno's lack of interest in sports forces him to enter the quietest club of all; the photography club, instead of entering the soccer club with Yaguchi. However, he will soon discover that the club is not what it seems and that the members of it are actually engaged in having sex with the other students of the school, which is why the club is also called "Yarichin Bitch Club".
