Paya Livingston

Punie's "mascot" and constant companion, Paya-Tan is a dog-like animal with a unicorn's horn that is personified as having two distinct personalities and faces. While assisting Punie he acts cute with a high voice and silly talk, but when they first met he acted harshly towards her and responded to her attempts to make him her mascot with violence. He may still wish to betray her, despite helping her on various occasions. When not with Punie, he may reveal his more adult face and deeper voice - and smoke a cigarette. In the past he also served as an army colonel.
