Rosie is a perky vampire; she's very hip and while she doesn't really need to work out what with her being undead and all, she enjoys physical activities like hiking, pilates, yoga, and jogging. Before she was a vampire, she was actually a vampire hunter who fell in love with a vampire she was hunting...she let him turn her into a vampire, but then left him after she realized he just wanted her for part of his undead harem, not a monogamous relationship. She regrets changing for someone else, but is still an optimistic and cheerful gal. Rosie can get a little competitive, though.
