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.

‎主角是里宁高中的一名大四学生。山城日宁市唯一的学校。主角，是高中的学生校长，还有另一个隐藏的角色。作为“轮奸俱乐部”负责人的角色...‎ ‎在里宁老城区存在一个已经流传了数千年的黑暗仪式;特别是仪式的名称，在最古老的记录中。该仪式是为了保护该地区免受疾病和作物歉收的影响而制定的，作为该地区守护神 Hime Iwanaga 的诅咒，发生在新月和满月之间的夜晚，其中一名少女伪装成 Konohanasakuyabime 并被以安抚 Hime Iwanaga 的愤怒。关于少女，必须有一个重要的男人参与轮奸，换句话说，该男子必须与他们的妻子或情人，母亲或女儿，妹妹或姐姐等有血缘关系，并且在轮奸之后，如果发生怀孕，岩永姬的愤怒就会减轻， 并将保证该地区的丰收和安全。但是，如果为了压抑岩永姬的愤怒而没有怀孕，少女应该被精液覆盖，并活着漂浮在河上，作为祭品。‎ ‎而现在---在扎西翁时代之后，仪式本身已经消失在黑暗的历史中，但仍然在日宁高中继续;残酷、不正当的传统通过轮奸俱乐部的行动被继承到一个秘密社会中。几代人以来，高中的学生校长一直担任轮奸俱乐部的负责人，甚至不允许有一天平安无事地过去，将无数女性淹没在黑暗，令人窒息的快感中。‎

En des temps anciens, dans le village de Rinin situé au pied de la montagne de Rinin, un rituel fût créé pour éviter la malédiction de la divinité Hime Iwanaga. Pour contrer cette malédiction, à chaque nuit qui séparait la pleine lune de la nouvelle lune, le village de Rinin organisait une cérémonie dans laquelle une femme subissait un viol collectif afin de calmer la colère d'Hime Iwanaga. Les années passèrent et avec le temps, cette raison a été oubliée malgré que les actes de viols continuaient de perdurer au sein de l'école par le Rinkan Club, dirigé par la Présidente du club... Tamura Motoko.

Basé sur le jeu pour adulte de Lilith.

Vor langer Zeit, in der Tashio-Epoche, existierte in der ländlich gelegenen Stadt Rinin ein dunkles Ritual. Dieses diente dazu, durch Ausübung einer Massenvergewaltigung und die darauffolgende Schwangerschaft des Opfers, die örtliche Schutzgöttin Hime Iwanaga zu besänftigen. Hunderte Jahre später existiert dieses Ritual nur noch in wenigen Aufzeichnungen alter Bücher. Die Öffentlichkeit sollte nie erfahren, dass diese Tradition in einer geheimen Gruppierung namens „Rinkan Club“ weiterlebt. Über Generationen wurde hier das alte Wissen weitervererbt, so dass momentan die Präsidentin des Schülervorstandes der Rinin Oberschule, Motoko, zugleich auch der Kopf des Rinkan Clubs ist. Als dann die junge Lehrerin Suzuko Yamasaki nach langer Abwesenheit in ihre Heimatstadt zurückkehrt und hinter das Geheimnis des Clubs kommt, versucht sie mit allen Mitteln deren Praktiken zu beenden. Doch schon bald findet auch sie sich wieder in einem Strudel dunkler Lust und Begierde …
