Amazing show. Takes the whole concept of "magical girl" shows and throws it out the window. Very dark and emotional concepts thrown into a beautiful looking world with great characters. This is a must watch.
Good show but it was WAY too short. This should have been 24 episodes at least in order to really flesh out the other characters and their backstories. Still, it's a great show.
This is the most emotional anime that I've ever seen in my life. Probably my favorite anime ever so do what ever you can to watch this ASAP.
