Having solved a certain incident, she rose to the position of a lady-in-waiting for Lady Gyokuyou, a high-ranking consort. She is favored by Lady Gyokuyou and liked by the other ladies-in-waiting, though Lady Lishu's attendants fear her. Jinshi has taken a liking to her, much to the exasperation of Gaoshun, Jinshi's subordinate. She addresses Jinshi with the honorific '-sama'.
