The story takes place in a particularly hot summer in the nineties, in a small quiet village called Sotoba. A series of mysterious deaths begin to spread in the village, at the same time when a strange family moves into the long abandoned Kanemasa mansion. Toshio Ozaki, dean of the only hospital in Sotoba, initially suspects an epidemic. But as investigations continue and the deaths begin to pile up, he becomes convinced that they are the work of the undead plaguing the village. A young man named Natsuno Yuuki, who hates living in the village, begins to be pursued and surrounded by death. (Source: Wikipedia) — Description from AniList community (anilist.co).
