On the surface, Shiina Chizuru is a proper (albeit a bit uptight) schoolgirl. Her sharp tongue and a sense of morality have gotten her in trouble with her peers and teachers on more than one occasion. Additionally, she carries a secret crush on one of her teachers, a young and dashing Tsukino.

After accidentally getting involved in an incident involving embezzling school funds, however, she finds herself at the mercy of her fat middle-aged teacher Tamura.
