Kamisama no Inai Nichiyoubi

Synopsis:

15 years back, God relinquished the world. People are no more conceived, the dead no amazing. In this forsaken world, the main ones who can offer peace to the dead are the "Gravekeepers". On this day, the Gravekeeper Ai meets her fate. Hampine, a man with red eyes, bewildering magnificence and silver hair and calling himself the "man-eating toy" shows up before her. Ai leaves on a voyage with him after he executes everybody in the town, trusting him to be her dad.
