The Nurbatch were a demon species with the green skin, which had a mouth in the shape of a beak. Although they looked cowardly, it was a misleading appearance. Their head hid a gigantic, insect-like creature. A member of this species was taken hostage by Gio, Rondell, and the rest of Gunn's Crew in Caritas. When the Transuding Furies broke the anti-demon-violence spell, the Nurbatch's parasite came to light and devoured Gio's head before being shot by Rondell.
