五十嵐 春香

Ryuichi's senior at school, a delinquent. Believe it or not, she's dating Mr. Nomoto, the PE teacher.

After Ryuichi caught them having a secret rendezvous, she dragged him into her sex circle to keep him quiet. Nomoto seems unhappy about it, though...

She calls Nomoto by his first name, “Takaaki.” Nomoto seems to be under Haruka's thumb. However, it seems she always makes him go “bareback & cum inside” except on her dangerous days.

She's actually the type of “good woman” who devotes herself to men.
