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.

An elite high school had another face hid in the dark side. In return for sending sex salves to the collages, they received a lot of money as contributions. Those who trained sex slaves were disposable teachers (trainers) who could keep the secrets. They hired talented men as temporary teaches to train. If they found a promising person, they asked him his will and made him take a test. The test was to lecture those who were defined as problem students. However, lecture is merely nominal, and actually it was training for sex slaves. If he achieved a good result, he would get a qualification of teacher (trainer).
Simazu had had an affair with his student, and was expelled from the school. Because he was branded as a harasser, no schools wanted to hire him. But only this school had hired him as a temporary teacher, and he had worked for six months. One day, the deputy school master called him and shown him an offer to become a trainer. Of course, he couldn’t refuse it. He resolved his mind, and made the students his games.
