I don't know..I watched 5-6 episodes a long time ago and didn't like it...But then again it happened with many animes but after watching them again I liked them...
Basicly I'm gonna watch the anime again very soon and then I'll post the rating.
I would give this anime a 9/10. Its one of a kind anime. Although it may seem serious and lacks comedity, it really had me glued onto my seat and watch it continuously for 2 days!! its an awesome anime!
