Also known as Prince Su, he is the head of the Court of Judicial Review and Yao Shu's superior. He is described as having long brows slanting into his temples, eyes bright as stars, black hair bound with a golden crown—an elegant figure like jade and pine. Though he appears cold and merciless, he is fiercely protective of his subordinates. He is quick-witted and skilled at deducing clues from evidence.
