Donny is a member of the Katz Street Troupe. Donny is a tall teenager, with long red hair and is a bit burly. Donny wears a white button-down shirt, which leaves part of his chest uncovered, and black pants with some kind of pockets on the sides, and a pair of light-colored boots. Donny used to train as a Holy Knight apprentice under his uncle Howzer alongside his friend Edlin. However, seeing that he lacked the strength to become a Holy Knight, Donny dropped out of training and joined the Katz Street Troupe alongside Katz and Elva.
