Xiao is a Yaksha Adeptus Anemo introduced in update 1.3 for the event wish, “Invitation to Mundane Life.” This polearm-wielding playable character is the last surviving member of an elite band of Yakshas or “illuminated beasts” tasked with fighting demonic spirits in Liyue. Although Morax himself dispatched his group of Yakshas with protecting Liyue, Xiao doesn’t seem very interested in interacting with the human inhabitants of the town. You can find Xiao in the Wangshu Inn in Liyue, but he won’t join your party unless you win him via the Character Wish banner.
