I'd have to say, this anime was one of the best anime's i've ever seen. I do wish it was longer though, because it's so amazing. All the emotion, and chemistry between each character, is incredible. I really love the animation. It was beautiful. Each character was also drawn lovely. The story line of this anime was very very good. It's a good anime for all ages. I never was bored while watching it. I finished it in one day. I reccommened this to anyone.
Okay well, you can probably tell that i LOVE this anime. It's kinda short, 13 episodes, but it's real good. I love it of course, because of the supernatural powers, and how the guys (Zero and Ichii) want to protect Nina, from all the other sorcerer examinies. It's pretty funny, romantic, action, and a lot of other stuff. I recommend it to anyone, unless your only into that whole blood fighting thing.
