Gwyllgi is a therapy Tokota to Damien by orders of his psychotherapist Matthias. When she is on duty, Gwylly is the poster child of obedience. As soon as the jacket comes off, though, she is a friendly, wiggly, playful puppy who just wants to cover your whole face in sloppy kisses. She has already seemed to pick up some of her handler's...mischieviousness...though, and when she's not with Damien, she enjoys lurking on rural highways at night to scare passersby. Damien proudly tells people that she is the source of the Welsh myth, though he's probably full of bull.
