Rinkan Club

A 4 episode OVA that focuses on a cult in the fictional town of Rinin where the cults main ceremony is gang rape a woman that is designated as a "shrine maiden".

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 Konohana Sakuyabime and gangraped to appease Hime Iwanaga's anger. In regards to the maiden, there must be an important woman participating in the gang rape, in other words, that woman must be related in blood to their husband or lover, family member, and even themselves. 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.

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. The OVA follows Suzuko Yamazaki as tries to put an end to the ritual.

The OVA was Pixy-Soft final work before animation work for Lilith-Soft, the people how made Taimanin Asagi, were transferred over to ZIZ entertainment.

Rinkan Club has Examples of:

• Absurdly Youthful Mother: Aiko Katsuagi. The woman looks great for someone with an adult daughter. Doubles as an "Absurdly Youthful Grandmother" after her daughters, Shiori and Maki become pregnant at the end of the OVA.
• A Date with Rosie Palms: A student raping Aiko in Episode 3 confessed he masturbated to her before.
• Adaptation Distillation: The OVA is much more condensed than the visual novel, and actually remove characters like the nurse Natsuko Hayasaka, and the students Izumi Shinohara and Chiaki Yukimi.
• Babies Ever After: The 4 women that were sentence to be "shrine maidens/priestess for life" all ended up being impregnated by the Rinkan Club.
• Big Bad: Motoko Tamura, the leader of the Rinkan Club. Although one can argue that Suzuko Yamazaki eventually take over the positions.
• Brother-Sister Incest: Poor Tomomi. Her own brother lusts for her and sacrifices the girl towards the raping club so he could have sex with her.
• Bittersweet Ending: The OVA ends with Suzuko becoming the new leader of the Rinkan Club and giving her Arch Enemy Motoko the Sexual Karma she deserves. Suzuko was able to abolish cult's old system, ensuring that most of the women of Rinin will no longer be victimized by the Rinkan Club's practices. However, to keep the customs going to satisfy her new followers, Suzuko decide that a few women and their future daughters will be "shrine maidens/priestess for life". Naturally, she chooses Motoko as one of the women who would spend the rest of her life being gang raped by the cultists. Surprisingly, she also chooses to sentence the innocent Maki Katsuragi, Shiori Nakamura, and Aiko Katsuagi to the same fate on the grounds that they are so mind-broken, it would be an Unishment to them.
• Cult: The titular Rinkan Club or Gang Rape Club.
• Full-Circle Revolution: Suzuko spends most of the OVA trying to put an end to the Rinkan Club. She was eventually able to wrestle leadership away from Motoko and took over the cult herself. However, Suzuko decide to sentence Motoko Tamura, Maki Katsuragi, Shiori Nakamura, and Aiko Katsuagi to be "shrine maidens/priestess for life". Which mean the Rinkan Club's ritual will continue, but using these 4 women and their future daughters instead of assigning a different woman from Rinin each month.
• Gecko Ending: The OVA has it's own original ending that does not happen in the original visual novel. The OVA ending has Suzuko take over the cult and condemn Motoko, Maki, Shiori, and Aiko to "shrine maidens for life".
• Hospital Hottie: Aiko Katsuagi, who is the only doctor in Rinin. There also Aiko's nurse, Natsuko Hayasaka from the visual novel.
• Hot Teacher: Both Suzuko Yamazaki and Shiori Nakamura.
• Human Sacrifice: Basically, what "shrine maidens/priestess" are, but instead of being killed, they are repeatedly gang raped by the Rinkan Club for about a month. The shrine maiden is suppose to represent the beautiful goddess, Konohana Sakuyahime. According to the cult's version of the legion, in order to spare the region from Iwanagahime, the village's guardian deity and Konohana Sakuyahime's sister who is envious of her sibling' beauty, from cursing the land, then a shrine maiden/priestess is needed every lunar cycle between the new moon and full moon for Iwanagahime mistake as her sister. A shrine maiden can only be appointed by a blood relative, a lover, or said person themselves by signing a paper robe.
• Loophole Abuse: What can be defined as rape? The Rape Club uses it to torture Suzuko by making her use a vibrator and write degrading words in her body, and forcing her to keep the paint on and use the vibrator even in class.
• Love Makes You Evil: Downplayed. Motoko become the leader of the Rinkan Club so that she and her eventual girlfriend, Maki, will not be designated as "shrine maidens".
• Male Gaze: Even when characters are clothed the camera tends to focuses on their legs, glutes and breasts.
• Maybe Magic, Maybe Mundane: Motoko follows the principles of the cult to the letter to make Suzuko become a sacrifice(by making Motoko's long-distance boyfriend unknowingly write her name on the paper used for offering), despite of the effort it takes. This implies despite most cultists not seeming to believe in the ritual, they do it in the proper way, implying they're not only replicating it for fun. Whether the legend is real or not is never made clear however.
• Mythology: The story of Konohana Sakuyahime and her older sister Iwanagahime from the cult's legion is actual real life folklore from Japanese mythology, just with the gang rape elements removed.
• Police Are Useless: It's implied by Motoko in the 1st episode that the police force in Rinin is being controlled by the club, hence why Suzuko can't seem to get anyone to help her stop the cultists.
• Schoolgirl Lesbians: Motoko Tamura and Maki Katsuragi, the two eventually become a couple.
• Token Wholesome: Tomomi Yamanaka and Maki Katsuragi, at least until the Rinkan Club gets their hands on them.
• Town with a Dark Secret: Rinin. As the entire village is being controlled by the Rinkan Club, and the authorities figure allows the cult to continue their depraved rituals.
• Unishment: Suzuko believe her "shrine maidens for life" sentence she gave Maktoko, Maki, Shiori, and Aiko would be this to them as they have become mind-broken to the point that they would actually enjoy spending the rest of their lives being gang-raped by the cultists.
