The name of one of the characters, I believe is called; Rena. Female, something like that. She is a vampire who is a friend with a male - human.
Things I remember:
*Vampires go red when they eat meat.
*Rena(?) and her friend are trying to get away from this other female vampire and her henchman(?)
*The evil female vampire sets her henchman on fire at one point.
*Towards the end Rena(?) can turn into a deer... >.>
