Hidden Village Feast Secrets Kotone Sacrifice and Family Bonds

In a secluded mountain village, the Kamishiro family and headman Kojiro orchestrate the Feast to address the low birth rate, providing women from their household. Mamoru and his sister Kotone, survivors of a fire, are taken in by the family. Kotone becomes the eldest daughter, while Mamoru serves as a servant. As the Feast approaches, Kotone agrees to participate, driven by her sense of duty. Mamoru, aware of the ritual, reluctantly cooperates, but unresolved tensions and hidden truths linger beneath the surface.
