A classmate of Handa's in 2-7, she starts out as a genuinely kind and reserved girl—until Handa unknowingly talks her out of committing suicide. After that, she becomes completely obsessed with him, developing an intense, stalker-like fixation.
Her nickname "Eraser" comes from two things: she literally "erases" anyone who gets in Handa's way or tries to bother him, and she's weirdly attached to an eraser he lent her early on, which she now carries around everywhere. It's kind of her thing.
