Ayachi Nene

Nene is both attractive and sociable, making her well-known around school. However, due to her secret identity as a witch, she avoids spending time with others outside of school.

The biggest problem is the 'price' she is paying that is part of the witch contract she exchanged: random, involuntary sexual arousal, with no care for time or place. Once Nene gets like that, the only way to return to normal is by 'relieving' herself through masturbation.

It isn't hard to imagine the difficulties she faces in everyday life dealing with that. It weighs on her mentally, and is the source of her frequent fits of self-loathing.
