Miko Mido is the descendant of the most powerful clan of female ninjas. After her grandmother dies, she is left with the heavy task of keeping the clan's status in check, while at the same time keeping the Shikima away from humans. The Shikima are horny demons who feed on the lust and desires of humans. Miko has to engage in sexual duels not only with the Shikima, but with the rival ninja clans as well. Sex battles where the one who "comes" first loses, and the last one to "come" wins. On top of all this, Miko is still struggling through high school... but why is Miko so closely bound to the Shikima? <br />
