This took really long to read and it is a good story. There were times when I got confused and mixed up about what was happening. The first time I read this, I skimmed and skipped thought it. Now, I am rereading it all the way through. I am still kind of confused with some of the relationships and developments. But. Towards the ending, it sort of made sense to me.
It's something, I can honestly say that, but at the same time it feels underdeveloped and rushed. It also felt like there are chapters missing but otherwise it was an interesting plot.
It's present-day, and Archangel Michael is fed up with the pathetic development of the human species. The angels, in their world high above ours, have been given the choice between destroying or preserving humanity. This will be decided by having "Plus Checkers" looking for good points and "Minus Checkers" looking for bad points, and whichever finds 10,000 points first decides the outcome. Chihaya and Kagetsuya are angels who have known each other since their days at military school in Eden, and having taken up opposing sides of this "good vs. bad points" checking system, are teamed together during their stay on Earth.
However, Chihaya is unusual even by angelic standards—he has black hair, eyes, and wings. He's one-of-a-kind, unusually powerful in spite of his naive demeanor (much to Kagetsuya's dismay), but set apart from his angel kin...until the Black Cancer strikes the heavenly population, darkening the wings and hair of its victims before spiraling them down into painful death. Tension builds among the angels and between Chihaya and Kagetsuya in particular, and it looks as if the secrets to the salvation or destruction of both Earth and Eden may lie with Chihaya himself.
