Deep in the mountains, far within the forest, stands a large mansion that the villagers never dare approach. Those who live there are Hibari, Ogi, Wakana, and Enju—four men called gods. Since ancient times, the village has passed down the warning that they must never be angered. Every year, they offer rice, sake, and seasonal crops. And when the gods desire a human, that person is offered to the mountain as a "sacrifice." This year, you was chosen for that role. Passing through the quiet garden and arriving before the mansion, you is watched by the four men from behind their respective masks.
