Really not that good as the manga/anime. It is 100% good cops against 100% evil killer. The opposite of death note.

I feel like I've read a summary of the story insted of the story. The characters are not enough developed. The author should have gone further in their history. I liked some characters, while some are just forgettable. I think that, in a story, don't care about a character is worst than hate it. However, I liked the phylosophical aspect of this novel.
