^Manga's way better.
Kamisama No Inai Nichiyoubi. (Some of you might know it as Sunday Without God)
Plot(copied from MAL): 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.
Rating: 6.5/10
Art: 8/10
Note: This anime is very slow-paced, which may seem annoying, but if you survived through the first three episodes you will definitely change your mind about it. It has extraordinary characters, too.
Note Note : JUST GO WATCH ITT ALREADY IT'S AWESOME!
