A handsome young man with a buzz cut, the young master of the Xi family in Kyoto. He has a hostile and arrogant demeanor, partly because everything in his life has gone smoothly and he has never been challenged. He was saved from death by Daoist Xuan Xu on his 18th birthday, which led his family to insist he become the Daoist's apprentice. He initially looks down on Li Miao due to her youth and gender, calling her a fraud, but gradually becomes more cautious after witnessing her transformation ability. He remains skeptical of her true power level.
