The Empress of Ninjago City was the coruler of Ninjago, the wife of the Emperor and the adoptive mother of Harumi. In spite of The Empress raising Harumi after her biological parents' deaths, her adoptive daughter secretly hated them.
The Empress and her husband were relatively private about themselves until they decided to speak out once crime continued to rise in spite of Lloyd Garmadon and his Ninja's efforts. She was killed during the Sons of Garmadon's attack on the Palace of Secrets during the theft of the Oni mask alongside her husband and Hutchins.
