This is a really good anime. The character development was awesome, and each character had an interesting story to them. The only issue I had with it was that the anime was too short to really allow time to expand on some of the more major characters. The action and fighting was amazing and really well made. The only issue I have with the anime is that it did not give you an ending. I don't think there will be a second season, but even then they just left it in the middle of story. But if you can look past an incomplete ending, itsa great anime.
