Just so you are warned, I am really bad at telling summaries. Especially when it has been a while since I saw the anime. (Gomen!) But here I go:
The title of the anime is Kamisama no Inai Nichiyoubi, translates to English as Sunday without God. As the tittle suggest, God abounded the entire world on Sunday. Humans are now unable to reproduce, and if he dies he does not truly die. The only way he can rest in peace is if he is buried by “a gravekeeper”, who God has appointed. Ai Astin (the girl in the picture below) is one of these gravekeepers. Through the anime, we follow Ai as she tries to find herself and about the world she is living in.
When it comes to sound and art I have nothing negative to say! The art is really beautiful and manage to make the anime come to life! The sound blends really well with the anime! Also, the voice actors did an awesome job! And not to forget the characters! They are so diverse and loveable! ☆d(o⌒∇⌒o)b
As this anime only have 12 episodes, there will be unanswered questions. But not the kind that it will bug you to death if you do not find out the answers! It is more like they are building up to a 2 season. (So they better make one! ಠ_ಠ ) But the plot is really unique and complex, as well as with some twist! And the amount of emotion and depth in just 12 stories really is amazing!
I definitely recommend this anime! Just make sure you have some tissues ready for the first few episodes ! ಥ‿ಥ
