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?
