About this season

Okumura, president of the Manga Research Club, once again spends his day alone in the clubroom, shouting the name of his beloved 2D character, Liliel, displayed on the screen…Then, to Okumura’s clubroom comes a 3D girl named Ririsa Amano, who says, “I want to become Liliel.” She loves the sexy and cute “costumes” of girls appearing in manga. And she’s a fellow otaku who loves Liliel just as much as Okumura! Ririsa reveals to Okumura that her secret hobby is cosplay, and she shows him a collection of ROMs filled with photos and videos of her cosplay to convey her passion.
