Shikkoku no Ten

A tranquil region is disrupted by an invasion from followers of the Lunar Religion, who spread a message claiming death is the only path to happiness. In a quiet village, a woman named Momo, who teaches at a local school, discovers a boy who has no memory of his identity or background. She takes him in, giving him the name "Ten." As the religious group's influence spreads, the village faces increasing danger, raising questions about what will happen when their presence reaches Momo and her home.
