Kamisama No Inai Nichiyoubi

god abandoned the world on sunday. as a result, nobody in the world can die or reproduce. a little girl, ai, is the gravekeeper for a village. she has prepared 47 graves for the eventual deaths of every member of the village. later, a boy who identifies himself as “hampnie hambart, the 'man-eating toy',” which is coincidentally the name that ai's mother left behind as the name of her father, arrives in the village and slaughters everybody. just what is going on?
