A Piruma is a omnivorous animal of the desert, it resembles a horse almost exactly, except for its sharp pointed teeth. They are commonly domesticated and used for transportation by the tribes of the Red Desert and are considered a valuable part of a family's wealth.

Wild Pirma are not common, but can be found in northern part of The Field of Demon Beasts. Most Pirma seem to prefer eating vegetation, Yulian's Pirma is unusual in its aggression and tendency to hunt and eat meat, which may be a necessary adaptation for those that live within the Field of Demon Beasts.
