Marivel (originally Mariabelle in the Japanese version) is a near-immortal Crimson Noble, a type of vampire. One thousand years ago, she was friends with Anastasia Valeria, the Sword Magess, and helped her defeat the demon, Lord Blazer. Oddly, it was during this encounter that she first met Ashley Winchester in a dimensional rift, an encounter that left enough of an impression on her that she sought him out 1000 years later.
