Kamisama no Inai Nichiyoubi

Synopsis

Hampnie introduces Ai to Scar, a true gravekeeper and questions her on the whereabouts of Hana, but upon yielding no results, tasks her with burying the villagers. Scar reveals that Ai is indeed a gravekeeper since she already took care of the burials much to Hampnie's surprise. Afterwards, Hampnie mercilessly questions Ai on what she intends to do now that she has nowhere to go. Suddenly, Hampnie is shot by Julie Sakuma Dmitriyevich, his childhood friend who claims of wanting revenge for Hampnie "killing" his undead wife. Revealing his immortality, Hampnie deduces Julie's cowardice of wanting to die for "revenge" rather than by his own hand due to the pain of losing his family. Unwilling to listen, Julie threatens Ai and demands a duel from Hampnie, who seems to accept. Ai resolves to remain being a gravekeeper and leaves the village with Hampnie who disregards the duel with Julie. That night, Hampnie realizes that twelve-year-old Ai is an anomalous human/gravekeeper hybrid, since humans were denied procreation after God's Abandonment fifteen years ago. He explains his belief that God had grown weary of his duty and resorted to granting desires, the first being humanity's wish for eternal life followed by his own of true immortality to overcome his weak body. Sometime after the Half-Dead Fever Pandemic gripped the world whereby the dead started walking, and the mysteriously appearing gravekeepers were the only ones who could help the undead find peace. Hampnie adds that if a person dies a clean death, they barely change but over time they regress into a horrific monstrous state which is why he put down Julie's wife. Finally, Ai asks Hampnie why he killed the townsfolk and he reveals that she would eventually find out, along with the secret hidden within her village.
