I started out reading the manga and fell in love with it! So when I heard the anime was going to be released I had high expectations. And for the most part all of them have been met so far.
I love the characters, I think they have been very well thought out and glide right into the entire theme of the story. The art is great, but not outstanding. Specifically Zero, I thought came out looking different than expected. However I have grown to like his image.
Overall this anime never fails to entertain with each episode, it makes sense and the storyline never gets boring. I think the hidden emotions are best fitted for the characters that they have been given to. Also, something important, I think the anime follows the story line of the manga pretty well. Not perfectly, and there are some things that have been changed but overall I would love the story even without reading the manga prior.
Kudos VAMP KNIGHT!
