Gomoramaru (強毛裸丸) is a shikigami used by Pato Keikain. It has the appearance of a giant black cyclops whose muscular arms and legs are held together by ofuda. It is called the "original shikigami" and is also the strongest shikigami of the Aika branch. It can become a chain composed of mantra which is capable of immobilizing yōkai, though this chain is proven to not be strong enough against Hagoromo Gitsune. Gomoramaru is seemingly destroyed by her at Kinroku-ji.
