I think this manga had a big potential to be something different, to create a huge universe with a bunch of stories and mysteries, but from the very first moment they threw all of this away. The storie advance really fast and you dont have enough time to relate to any of the characters, appart from the two/three principal characters you easily forget the names of all the secundary characters. Also, because of its similarities to other mangas sometimes you can predict what is about to happen. In my opinion its a manga that you can read in a couple of hours and only if you are complety boring and have nothing else to do.
