This is a great and intense show!! I do have to say it was a bit slow in the beginning, but it picked up very quickly. Many don't like this show because the don't understand the plot since it is complex, but the story is good. The music is one of the greatest contributions to this show. The opening and ending theme are very catchy, and the music during the actual show is great too. My favorite part of this show is the complex storyline. Some other nice things about this anime is the action and conflict distributed between the characters. Another cool thing about this anime is that everything connects. Any die-hard anime fan will want to check this one out.
