Anime News Network: Fifteen years ago, God abandoned the world. As a result, people stopped dying and having children, continuing on long after their hearts had stopped. In order to truly be laid to rest, they must be buried by a Gravekeeper, a mysterious being with a special shovel who can truly “kill” the dead. Twelve-year-old Ai is an anomaly in this world – she is half-human, half-gravekeeper, born three years after all other children. With a spirit of innocence and hope, Ai travels the world in an effort to save it by showing people a happiness and peace that they thought lost – either in life or in death.
