Long, long ago, during the Silver Millennium, Raye lived as the Princess of Mars. All was well until Queen Beryl and the Negaverse attacked, destroying the Moon Kingdom. Princess Serenity's mother, Queen Serenity (go figure) used the Silver Imperium Crystal to send them all to the future to be reincarnated.

In the present timeline, Serena, Luna, and Amy first met Raye at the Cherry Hill temple when investigating the disappearances of girls who had gone up to the temple to buy charms. Raye suspected Serena of being evil and whacked her with a spirit ward, which may have been the start of their constant bickering. Luna sensed something about Raye and left her a transformation pen, which she used after being sucked into an alternate realm by Jadeite. She is constantly doted upon by Chad, the rock musician who came to the temple to learn their ways, but she does not return his feelings. Before Serena dated Darien, Raye temporarily went out with him, who dated her more out of pity than out of admiration.

After defeating the Negaverse and Queen Beryl, she lost all of her memories of being Sailor Mars and didn't remember until Alan and Ann attacked her at an audition and Luna restored her memories, as well as the other three inner scouts.
