It is a great anime only if you watch the whole 2 seasons because it doesn't make much sense if you just watch the first season. When I first watched thisI cant understand the asura cryin thing or anything about the 1st world stage or something but after watching the second season, I was like "oh this is the best anime I have ever seen".It has a nice story, nice art, lovable characters and I really enjoyed it. No matter what others says this is a good anime for me.
