Xiao is also heralded as the "Vigilant Yaksha" or the "Conqueror of Demons." For millennia, stories of his exploits have been told. He exudes a reserved demeanor and is uninterested in interacting with mortals. He is known for his combat prowess and dislike of most human foods, with the exception of almond tofu and grilled tiger fish, the former reminding him of the dreams he used to consume and the latter honoring the late Pervases.
