The story is about a school, Shiritsu Yurihime Gakuen, an all girl school specialized in preparing maid for the otaku moe industry. Of course, the leader is no less, a Nakabayashi, a heavy-class otaku with unlimited asset to burn for while seven generations. Our main heroine this time is Mochida Natsumi, a girl with hentai mind as worse as Yoshitaka and luck as bad as Izumi. She came with the ambition of building harem of imouto. But life is not as beautiful as in those harem love comedy genre anime/manga, because in this school, all the girls are well educated in otaku business.

Yoshitaka Nakabayashi, a 14-year-old millionaire who got this huge inheritance after his parents died in an accident, found himself needed to be taken care of and tried to hire live-in maids to do the job. Two runaway girls, Izumi Sawatari and her younger sister Mitsuki, stumbled into Nakabayashi's mansion and got hired by Yoshitaka immediately, for Yoshitaka is not only a rich boy but also a pervert with uniform fetishes, who wants to be addressed as goshujin-sama (master). Having nowhere else to settle down along with Mitsuki's pet alligator Pochi, Izumi accepted the job reluctantly.
