H00535 Rinkan Club Ep 1: Ancient Ritual

In the mountain town of Rinin, a student leader hides a second identity as head of a secret club that perpetuates a dark tradition from ancient records: during nights between the new moon and full moon, a maiden disguised as Konohanasakuyabime is raped to appease the guardian deity Hime Iwanaga, with the requirement that an important man related to the maiden by blood participate, and if pregnancy does not occur, the maiden is covered with semen and floated down the river as a sacrifice. The ritual had supposedly vanished after the Taisho era but continued secretly. Now it resurfaces.
