Oni

are hideous yōkai, usually wearing little to no clothing and possessing large claws, fangs, and horns. A notable exception to this rule is Urasue, a ogre sorceress. The Inu daiyōkai Sesshōmaru often rode on the shoulders of large, red oni over a hundred feet tall into battle, before he obtained the demon-sword Tōkijin.
