Xiao is a short and sturdy-looking boy with amber eyes and dark hair with turquoise strands and red eyeliner. He is not a human being, he is a yaksha who above all cares about his duties and loved ones, to the point that he forgets to take care of himself. He avoids touching because of his karmic debt, which causes him great pain. He is often harsh and does not understand most human customs and social norms..
