Kashiwazaki Haruka

A female teacher who prefers younger men and is secretive about her fujoshi tastes. Even though she has lewd fantasies about her students, she is afraid of losing her job if she is found out.

She is now a woman who has been accumulating her pent-up sexual desires, and spends her days masturbating in an empty classroom on days when she has overtime work.

When the protagonist witnesses her doing so, she ends up eating him to keep his mouth shut. In effect, she became the first person with whom he had sex without Anri's possession.
