This character is the granddaughter of a powerful figure, whose parents were tragically murdered by a relative, a secret she carries. Her ability to speak was suppressed in childhood by her grandmother, forcing her to communicate through writing. As a direct descendant of the main Sa line, she becomes a source of conflict during family power struggles. To ensure her safety, she is secretly protected by Shōrin and Yōshun under the direction of Ensei Ro. She later utilizes her unique abilities to aid in rescuing Kokujun and forms a deep bond with him as he assumes leadership of the Sa clan.
