Mandou Kururu

She is a hafu and moved here from overseas when she was little (she can't speak her foreign language anymore). She is shy and doesn't want anyone to see her bare face, thus she lets her bangs grow long to cover her eyes.

She adores the protagonist, who's her "senpai", but can't express her feelings honestly. Instead, she teases him sexually to get close. Because of this, they've ended up in an adult relationship without being proper lovers. She's perfectly satisfied with the way things are.

Despite all the teasing, she's a total masochist, repeatedly climaxing instantly and losing control.
