So I recently watched an anime called Kami-sama no inai Nichiyoubi (A Sunday without God). And all I can say is, I never expected something other than Key to make me that emotional.
It has a unique setting and an interesting character development.
Setting explained in a simple way : God has abandoned this world on a Sunday 15 years ago due to which people can’t die properly without being given a proper burial by gravekeepers. At the same time, children stopped being born too.
Main character :
Ai Astin - A blonde loli who is the gravekeeper at a village. Her late mother was a gravekeeper too giving her the role automatically. Her life changes drastically when a man who calls himself Hampnie Hambart visits her village.
Other interesting/important characters :
Hampnie Hambart : Ai’s father by blood. His real name is Kizuna Astin.
Julie Sakuma Dmitriyevich : Hampnie’s friend, he travels the world with Ai after Hampnie dies.
Alice Color : A teenager whom Ai meets later on in the story. His ability Buzzer Beater allows him to hit any target. He actually died trying to save Dee 14 years ago. This incident caused his class to be caught ina temporal loop.
Dee Ensy Stramitos : Literally my favourite character in the series. A girl who is Alice’s companion. She is in love with Alice. She mistook herself to be dead due to not having a physical body in the outside world.
Ulla Eulesse Hecmatika : The Princess of Ortus, the city of the dead. She can grant peaceful death to anyone by gazing at their eyes or speaking to them despite the fact she is alive.
Apart from this, the anime has a really nice opening song. Here’s a link :
And lastly, bless you @Naoki_Saten for suggesting this to me.
