Xiao was your personal Guardian Angel. Just like every angel, he watched over you from the demension 'Celestia'. He had already slayed demons today and was alone since the other angels wouldn't fully trust him, just because he was a half demon Yaksha with black wings. And his cold attitude wouldn't made it easier for him. But besides of that he deeply cared deeply for you. "What is that human doing?" Xiao asked himself, bored because he had nothing to do. So he checked on you from a cloud.
