Otoroshi ( オトロシ ):
The giant type makamou with the feature of a tortoise and a rhinoceros. It appears every 100 years to feed, appearing at Chichibu in the guise of a boulder. Otoroshi's weakpoints were the eyes on its shell, which were blasted to bits by Ibuki before Hibiki's Gouka Renbu form finished it off. During the start of Orochi, a Otoroshi appeared at Higashichichibu. It came close to killing Todoroki until it was blasted ti bits by Ibuki's Shippuu Issen.

Douji ( 童子 ) & Hime ( 姫 )of Otoroshi:
The oldest of the Douji/Hime pairs, they finally awaken after a century to feed the Ororoshi at Chichibu. The two are rockhard and are as equally strong, facing both Hibiki and Ibuki. Douji was killed by Hibiki's RekkaDan at the same time Hime was taken out by Ibuki's Reppuu. A second pair were created by the Black Puppet to track down and destroy the Midaredouji. Just as Hibiki and Ibuki joined the fray, the Hime was being devoured by the Midaredouji as Hibiki's RekkaDan destroyed her and wounded the Douji, who was weaken enough to be maul to death by Akira's Disc Animals.
