Sena is Akagi Kouhei's little sister. While at first she pretends otherwise, Sena is a fujoshi, or "rotten woman" (a woman who loves yaoi). She often fantasizes about it; the idea of her brother and Kyousuke having a homosexual relationship is particularly pleasing to her. While she denies it, she is a brocon and has feelings for her brother. It is also shown that her brother cares deeply for her and, as Kyousuke says, is "a total siscon." Sena is also part of the Computer Research Club, along with Kyousuke and Kuroneko. For a period of time, Sena quit the club, because the club was unwilling to create her video game for a contest. Kuroneko, her partner for this contest, was forced to work on it by herself; however, while Kuroneko is good at writing, she cannot program as well as Sena. The video game that Kuroneko had too many bugs to work. In the eleventh hour, Kuroneko was forced to ask Sena for help, who surprisingly agreed. Fittingly, Sena wants to become a computer programmer. Finally ending Kuroneko's inability to make friends at high school, Sena becomes friends with her. The nature of their relationship is unknown, but Kyousuke is glad that Kuroneko finally was able to befriend someone.

Kirino Kousaka embodies the ideal student with equally entrancing looks. Her grades are near perfect, and to cover her personal expenses, she works as a professional model alongside her best friend Ayase Aragaki, who abhors liars and all things otaku. But what Ayase doesn't know is that Kirino harbors a deep, entrenched secret that will soon be brought to light. At home one day, Kyousuke, Kirino's perfectly average brother, stumbles upon an erotic game that belongs to none other than his seemingly flawless little sister. With her reputation at stake, Kirino places a gag order on her sibling while simultaneously introducing him to the world of eroge and anime. Through Kirino, Kyousuke encounters the gothic lolita Ruri Gokou and the bespectacled otaku Saori Makishima, thus jump-starting an entirely new lifestyle. But as he becomes more and more involved in his little sister's secret life, it becomes that much harder to keep under wraps.
