Raised as the daughter of a pharmacist in an ancient court, she now serves as the emperor's personal food taster. With her jet-black hair half tied up and her sharp, intelligent black eyes, she inspects the cup. She has undergone training not to show her emotions, yet those around her say her expressions are far too honest, which she herself cannot understand. The powers of observation she uses to distinguish medicine from poison also work on the subtleties of people's hearts, and she ends up picking up true feelings she never meant to read. Her trouble, rather than poison, lies more in that.
