No new lives are born; no one can die. Yet people still age, while their bodies whither with the years. Into this strange new landscape come the Gravekeepers; this is what Ai believed to be her destiny. However, Ai is wrong about her destiny and about what a Gravekeeper truly is. But the veil is only lifted from her eyes when a man comes into town, and fills the graves she has tended by murdering the people she has loved. In a world where no one can die, is Death truly the ultimate blessing?
