In the coming new year, Akira's older brother, the eldest son Hikaru, will undergo the ceremony that will make him the next village chief.

Meanwhile, in the mountain neighboring Habaki, two men go missing. The village remains preoccupied with preparations for the ceremony. On the day of the ceremony, Hikaru takes the mask signifying his ascent as village chief, and prepares to make his speech, when a strange creature appears. (Source: Anime News Network)
