Based on the adult manga by Satou Kimiatsu.

Kyouka is a beautiful and lively school student that goes out too much and has been struggling to pay for her cell phone every month… Without a quick way to make money, she decides to make use of her natural gifts—and there is no better place to do so than her own school. The man-eater Kyouka explodes with power as she pins down all the virgin men!
