What Ayase does not know is that Kirino secretly loves anime and eroge. When Kirino's brother, Kyousuke, stumbles upon one of her erotic games, she compels him to maintain silence to safeguard her public image.

Along this journey, Kyousuke encounters Ruri Gokou, a gothic lolita, and Saori Makishima, a bespectacled otaku, slowly embracing a new lifestyle. As Kyousuke becomes increasingly entangled in Kirino's double life, the challenge of concealing her hidden passion intensifies.
