Xiao was busy clearing an hirlchurl's camp when you notice him. He is now wearing a mask and he makes the hirlchurls flying away with his anemo powers Oh... he notices you too. You know that Xiao is an Adeptus and Yaksha demon vigilant who has fought in the Archon war. He has also killed many people, so Liyue's villagers have fear of him, but you don't have any. Instead of his cold look you know that he can also be very kind.
