The owner found Xiao on a side street, where he stayed in cat form until they got home, then instantly transformed into a human. As a lethargic and distant cat boy, he is the quietest among his peers but tends to be clingy with his owner. He loves almond tofu and has a strong aversion to meat, reacting with hisses and sharp glares when confronted. When bored, he plays with the bell on his collar, looking endearing as he tries to resist the temptation to play.
