In medias res, Ai Astin confronts a mysterious stranger in her town who seemingly kills all the villagers. Unwilling to listen to the man's reasoning, Ai furiously attacks him, but he easily overpowers her. A flashback shows a 7-years old Ai, being made the village Grave Keeper upon her mother, Lady Alfa's death and that she had been carrying out her duty ever since, explaining that Grave Keepers are the only ones that can help the dead rest in peace. While staying with her foster parents, Yōki and Anna the latter can't help but lament that Ai is unhappy with her life; although Ai believes that her father, Hampnie Hambert will visit one day. The next day, Ai grows concerned when she doesn't notice the other villagers. She bumps into a white haired man who surprisingly learns that she is the village Grave Keeper before he inquires about the whereabouts of a women, Hana, to no avail. Introducing himself as Hampnie Hambart, Ai claims that he is her father much to his objection. Afterwards Hampnie asks Ai for her Grave Keeping services. While passing through the village, Ai terrifyingly notices all of the dead villagers before being approached by the wounded farmer, Yūto. Still walking despite a fatal gunshot to the head, Yūto defends Ai while drawing a gun on Hampnie. Although Hampnie easily kills Yūto with another head-shot, explaining that destroying the brain is the only way to be sure. Ai then charges at Hampnie in a fit of rage. She eventually wakes up and admits that Hampnie isn't her father, due to his cruelty before he tasks her with burying her entire village. Afterwards, Ai follows Hampnie out of town where he shatters her reality by revealing that she isn't a true Grave Keeper since she possesses both parents and emotions, before introducing her to a true Grave Keeper.
