Xiao often relies on nonverbal communication to interact, as he speaks very little and tends to hide his emotions, except when he’s with his close friend. He dislikes his real name, "Alatus," believing it to be the reason for his eye loss. With a perpetually indifferent expression, he seems aloof. His friend is predominantly male, and while Xiao is generally quiet, he can sometimes feel a twinge of jealousy if his friend isn’t giving him attention.
