High school student Hiroki is a perfectly average guy, except for one thing: his insatiable fetish for glasses. Due to this fixation, Hiroki rarely goes a day without engaging in sexual activities with his girlfriend, the gorgeous, glasses-clad Hitomi Kurumizawa, in his home. One day, however, he is caught in the act by his older sister, Natsume—a bespectacled beauty—who decides to “punish” him for the noise caused by his escapades.

Kis’s father has a disdain for his son’s lack of a job and desire to be a painter. When he shows up at his house, his father decides to punish Kis by offering his beloved maid, Nanaly, to strangers while Kis watches.

She was a pretty girl you might find in any town. Most people would look and see an innocent. Not one guy. One guy imagined her begging, tearful face and got aroused.

He didn’t even realize how deep his sadist desires went. He began to stalk her. He looked for anything to feed the fantasy that she was a dirty whore. A justification. And then, a single DVD arrived in the mail.

The DVD was a secret gathering in the home of a wealthy family,
where adults helped themselves to a young girl. The young girl was Sayaka. The sex was rougher than anything he’d ever seen.

Several days later, the person who sent the DVD
made a request. “I know who you are. I want an amateur with your sort of perverse interests to do some training.”
A drug was provided. It was a drug used to make the gathering video. Sayaka lived for it. She existed to taste it.
Her hunger for the drug made her beg and plead…
The desire that marinated his sadist heart now aimed at her.

The main character is a senior who attends Rinin High School; the only school among the mountain town of Rinin City. The main character, who is the student president of the high school, has another hidden persona. The persona as head of the “Gang Rape Club”…

A dark ceremony existed that had been handed down for thousands of years in the old town of Rinin; the name of the ceremony, in particular, in the oldest of records. That ceremony, enacted to protect the region from disease and crop failure as a curse from the region’s guardian deity, Hime Iwanaga, occurs in the evenings between the new moon and full moon, in which a maiden is disguised as Konohanasakuyabime and gangraped to appease Hime Iwanaga’s anger. In regards to the maiden, there must be an important man participating in the gang rape, in other words, that man must be related in blood to their wife or lover, mother or daughter, younger sister or older sister, and the like, and after the gang rape, if a pregnancy occurs, Hime Iwanaga’s anger is abated, and a good harvest and safety upon the region will be promised. However, if a pregnancy does not occur for the sake of suppressing Hime Iwanaga’s anger, the maiden is supposed to be covered with semen, and floated down the river alive, as a sacrifice.

And now—After the Tashio era, the ceremony itself had vanished into the dark history, but had still continued on at Rinin High School; the cruel, improper traditions being inherited over into a secret society through actions carried out by the Gang Rape Club. For generations, the student president of the High School has served as the head of the Gang Rape Club, not allowing even one day to pass uneventfully, submerging numerous women to the dark, suffocating pleasure.
