Utakata no Mujina

During his second year of junior high, Kentarou Himoto was sent to live with his grandmother after his parents found out that he "liked men." He ended up in a remote village called Mushinashichi. In this village, there is a strange custom: every year, at the summer festival, 15-year-old children are gathered to divine whether they will stay in the village or not, and Himoto is asked to participate...? A secretive village, a strange custom, and a destiny that cannot be defied... What will the fate of the boys at the mercy of this custom? (Source: Ichijinsha, translated)
