Try Is This A Zombie?

Skip Beat and Highschool of The Dead.

Moon Phase is a comedy, fantasy, romance Anime with Vampiri#From Dracula to Buffy... and all creatures of the night in between. and action. It's about a photographer who always takes pictures of ghosts, but is "spiritually dense". He unwittingly stumbles upon a young vampire imprisoned in a castello and is forced to free her in order to escape. Moon Phase goes from "cute" to "serious and dark" quite a lot with the first half being più lighthearted and the secondo half più dramatic. Personally I loved this Anime and the ending was extremely good for a first season. Although there are some plot holes that needed a secondo season to resolve. However, the ending doesn't leave te hanging as much as a lot of Anime out there does.
