Sēramu

was the mother of Sāra and the previous queen of Rōran.

Background
Sēramu lived a happy life with her daughter as the Queen of Rōran. They usually sang together while she played her harp. One day, a man calling himself Anrokuzan convinced her to use the power of the Ryūmyaku and his technology to make Rōran grew with thousand of towers for the sake of the people. However, Sēramu realised she was being used by Anrokuzan. As a result, she was murdered by the latter, who used his chakra strings to send a blade into her back from afar. Sāra replaced her as the new Queen, unaware of the truth behind her mother's death.
