Based on Ono Fuyumi's novel and Fujisaki Ryuu's manga adaption.Sotoba is a small village with around 1300 inhabitants. It is not connected even to a single highway. In that isolated village, some old customs, such as the burial of the dead, are still practised.One day, the corpses of 3 people are found. Although Ozaki Toshio, the village's lone doctor, feels uncertain, he treats the deaths as normal occurrences. However, in the days following, the villagers die one after the other.Is this mere coincidence, an epidemic, or something else entirely?
