Powers & Abilities ōmaken equipped with Ucchusma
While Ucchusma has not been seen in battle by himself, he is implied to be just as strong as his rival, the Impure King. He has the power to augment the flames of Satan through attaching himself to Rin's Kōmaken. He does this by transforming into a diminished version of himself.[3] In this form, Ucchusma is able to greatly increase the destructive power and range of his flames to the point where, in conjunction with Rin's own power, the two are able to create enough flames to cover an entire mountain. While Rin is able to alter the power of the flames to only purify and burn the Impure King's bacteria, Ucchusma implies that his power is able to destroy all the living creatures on the mountain.[5]
