This is a spinoff of the anime Kore ga Watashi no Goshujin sama, which follows the story of an all-girls school called Shiritsu Yurihime Gakuen. The school specializes in training maids for the otaku moe industry, and the leader is a heavy-class otaku named Nakabayashi with endless resources to burn.
Our protagonist, Mochida Natsumi, is a girl with a hentai mind as twisted as Yoshitaka's and luck as terrible as Izumi's. Natsumi dreams of building a harem of imouto, but her life at Shiritsu Yurihime Gakuen is far from the romantic harem comedies she loves. All the girls are well-versed in the otaku business, making it difficult for Natsumi to stand out.
Her roommate and "imouto," Kitamura Kiriko (a.k.a. Mitsuki 2), appears innocent but has a demonic personality to the bone. Despite this, Kiriko is also Natsumi's goshujin-sama.
