Harumi used to live in Ninjago City with her parents as a young, avid fan of the Ninja. However, after the Great Devourer’s attack on the city took her home and parents away, she felt as though she had died inside and grew to resent the Ninja. Her worship switched to that of Lord Garmadon, as he was the one that ultimately destroyed the Devourer after he was bitten by the Devourer and it was his revenge when he was a child when he and Wu were best of friends and training with Wu and One day while they were practicing their skills, Wu lost his katana and his older brother sought to find it, knowing their father would not be pleased. Garmadon found the katana after clambering over the wall, however, he is bitten by a small green snake.. She was later adopted by the Emperor/King and Empress/Queen and became Princess of Ninjago. While locked up in the palace, she trained to be smarter and stronger than before, started a crime group known as the Sons of Garmadon, and adopted the alias ‘The Quiet One’.
Through the Sons of Garmadon, she acquired the three Oni Masks, killing her adoptive parents in the process, all while masquerading as an ally of the Ninja and serving as a love interest to Lloyd Garmadon. She eventually betrayed the Ninja and Royal Family and used the masks to resurrect Lord Garmadon, then helped him take over as Emperor and King of Ninjago and Harumi and Empress and Queen of Ninjago. During a fateful battle with Lloyd's Resistance movement, Harumi attempted to flee a crumbling building but stopped to help save a family from the same fate as her own, but was killed by the collapse of the building.
