A girl from a good home, she comes from a wealthy family in the small village of Alexandria. However, contrary to her upbringing, she is unskilled in the social niceties and expected behavior of her environment, which often leads to conflict with her mother. She joins up with the Hero for personal reasons, strengthening the party with her flair for offensive magic. Something of a tomboy, Jessica is nothing like her mother, who expects her to be prim and proper in public.
