The phrase "jashin shoukan inran kyonyuu oyako ikenie gishiki" can be roughly translated to "ritual of summoning the evil spirit, chaotic and obscene, parental sacrifice ceremony." This ritual is believed to have originated in Japan during the Edo period (1603-1868), and is thought to have been practiced by a secretive group of individuals.

The Oyako, typically a family member or loved one, is led to the altar and bound with ropes. The practitioners then proceed to ritually sacrifice the Oyako, using a variety of methods, including strangulation, dismemberment, and burning. The sacrifice is believed to create a rift in the fabric of reality, allowing the malevolent entities to enter the world.
