This series is a about the life after death but before heaven and an organization in this life that is fighting against god. These people don't want to vanish an think fighting again the Angel is the only way to stay in this world. The theory is that if you just do as the NPC, or Non-Player Characters, do you will vanish. Their world is turned on its head when the new guy wakes up and then the story grows from there.
The plot in the beginning is good and the second half of the plot is different but makes the show more interesting. As the plot progresses, you learn more about the characters and why they are fighting. The story keeps up and the idea of afterlife is a major theme. The characters have great personalities and you will love them from the moment you meet them. Their histories are unique and their ideas for fighting are solid, without this stamina that adds to the atmosphere of the show it would be impossible to continue watching. The plot is solid and the characters are great. You will love this anime.
Total Rating: 5 out of a possible 5 One of Key studios greatest works. I recommend it.
