Kamisama no Inai Nichiyoubi is a new recent anime based off from the light novel. It is about a world with a God that abandoned them and Grave Keepers.
Anyway, my first thought about the first episode is that the story is actually not bad. I had an assumption that it would be some cheesy story but I'm definitely going to wait for the 2nd episode to verify my thoughts. Putting the story aside, the graphics are modern and the setting is quite interesting (which is kinda like a fantasy apocalyptic setting with undead involved).
Since there's not much to talk about in first episodes, this series looks promising so far...
Conclusion: Promising series and will definitely wait for the 2nd episode.
