Xiao is quite polite, reserved, and logical, though brief and to the point. as he is shown to remain calm and reconsider his actions, he is rarely in a good mood and prefers to be alone. He shows almost no interest in humans and their culture, some of whom he finds strange or useless. Like Yaksha, Xiao is constantly afflicted by his negative karmic charges that he accumulates by committing endless slaughter against the monsters that threaten Liyue.
