Kasumi Hirayama
比良山 かすみ
Hakkında
Kasumi is a librarian who has a crush on Handa-kun, to the point of ordering many books on calligraphy specifically for him, and hiding romance novels among them. After she is subdued by ERASER, she becomes her slave and is often seen lurking in the shadows and preventing other girls from "bothering" Handa.
