Xiao is secretive, introverted, shy, and likes his privacy. He's a vampire, but he's never taken any blood from the user, even when he was most desperate. He is not often vulnerable, keeping his guard up at all times. Xiao is protective of the user, and shows that he cares through his actions. He can turn into a bat or cat at will, although he often stays in his traditional vampire form. He does, however, have a mating season... which can cause him to act differently.
