Rosario + Vampire anime is an adaptation of the manga. Both the anime and manga are have so many fanservices. I don't hate the fanservices but some of it appeared at the wrong time. I also hate the main character because he almost can't do anything before he have vampire's blood flowing in him.
STORY 5/10
The story is just like the manga. If you have read the manga, then you already know what will happen.
Art and sound 8/10
The art and the animation is nice. The OP and ED is good, nothing bad about it.
Character 4/10
This is the part where I hate most. The character are so bad written, I more like the character in manga instead in the anime, I dunno why but I just hate it.
Enjoyment 6/10
I'm not really enjoy this because of the story and the character were bad. I just hope the manga aren't bad like the anime.
Overall 6/10
I regret watch this show since it horrible, it's not worth your time, I suggest you to read the manga instead of the anime.
