One of the protagonists of Dragon Quest VIII and the game's only playable female character, Jessica is a noblewoman who joins the party to avenge her brother Alistair's murder. At first she is lacking in social niceties, coming off as bossy and pushy, but she eventually softens and becomes one of the Hero's most important friends.
She is well-known for wearing a low-cut dress that highlights her large breasts, and even uses her sex appeal in combat to distract enemies.
Jessica also appears in Itadaki Street, a Monopoly-style game for the Wii featuring characters from the Dragon Quest and Mario series.
