Tokyo’s Valentine Call is a special kind of phone club. Older salarymen pay to wait for calls from teenage girls, discreet meetings are arranged, and handfuls of yen are exchanged for a quick session of enjo kosai, or paid sex with a high school girl. Plenty of girls are doing it—some to make money for fancy, fashionable clothes and accessories, others to set a trap to rob and brutalize the old perverts. But the Valentine Call staff, horny young Ogisu and the vaguely sinister, makeup-coated Mr. Kuni, have a nasty plan of their own. Listening in on the enjo kosai calls, they conspire to trick the girls into giving them free sex. Mr. Kuni even has a twisted concept behind this scheme. He calls it enboku, his campaign to humiliate the teenage girls, drive them away from prostitution and purify Japan.

In Tokyo, prostitution in the name of "Enjo Kosai" is in fashion among some high school girls. A mysterious man Kuni lament such girls but cannot deny a strong desire for them. He punish the girls by having sex with them without paying them. He calls this operation "Stop the Bitch Campaign" for public justice. Working in a sex trade shop where abnormal people are satisfied with their lust. Aoi tries to find out the man who raped her desperately in the past. One day, Aoi meets Kuni.
