At a certain shrine, miko were gathered and subjected to sexual acts under the guise of training, and forced to provide sexual services to the parishioners to ensure the shrine's survival. The rookie miko, Noa and Mikako, frequently misunderstood their duties, which their instructor Rena and senior miko Mihina reported to the chief priest. "It's about time we taught them the proper mindset of a miko..." they said, as they began the sacred sexual ritual.
