A village built on gratitude to something that kills. Every 60 years, seven girls die, and nobody reports it because the demon saved them once. The exorcist walks in blind, trying to stop a ritual that the entire town has agreed to protect. This OVA refuses the comfort of a simple evil, it corners you with the question of what debt justifies sacrifice, what silence justifies murder. By the end, there is no clean answer, only the weight of choosing between two terrible truths.

Every sixty years, a string of mysterious murders strikes the village of Kanoesaru, and each time the victims are seven girls aged seventeen. The villagers believe the killings are the work of a demon that once saved their village, so they say nothing about them. The current head of the Ibuki family wants to protect her two daughters, and she calls in an exorcist. What really lies behind the murders in Kanoesaru? This single-episode OVA from 1997 is a supernatural action story.
