Rosario+vampire was the first not main stream anime I watch and I have to say that i really enjoy it. The anime is not as good and the manga but if you go to it with a clear mind you will most likly enjoy it.
The story is about a guy name Tsukune Auno how fail his highschool entrence exams so his parents enroll him in a school the doen't require test to enter called Yokai academy. what they don't know is the the school is actually a school for mosters were they teach the how coexist with humans and is any human past the barrier that protect the school they would be killed in the spot. As luck has it he meets a beautiful girl named moka Akashiya how is a Vampire the get addicted to his blood. now with trying to hide the the school that his a human and moka form sucking him dry his going to find himself in an adventure of a lifetime.
the animation is decent with this anime is not the best animation out there but is not bad at all.
the music can be pretty addicting and just fun to hear, and also the voice acting is really good but the best is Nana Misuki playing moka, she steals the show.
the characters are intresting to say the less exept for Tsukune how seem the he has no purpose other that to be the love intrest of the other main characters until the half way point to the story.
with a few flaws the show i find it entertaining and i see myself coming back to it for some good laughs. recomende for those how like fanservice and like thing that are not serious wtih a story just don't expect it to be as good as the manga cause you will be desapointed.
