Probably one of the better animes I've seen in awhile. For someone who hates vampire legends and how they operate, this anime was pretty good. Story writing was great with very good story build-up, though it was a slow build-up. I do question Natsuno's character involvement with this anime. It's not unknown for a writer to write off a main character for an anime because it brings true detail to a story (because not everything ends in a happy ending), but his screen time was rather interesting. For a main character, he didn't get a ton of screen time for the second half of this anime, but his involvement to the story's plot serves a very important purpose and manages to become a hero in the end.
