Brimstone Art: Kagutsuchi is one of Nurarihyon Ayakashi's Brimstone Art techniques, and a very powerful jutsu. It is the middle in power of the three Brimstone Arts, stronger than Mihashira but weaker than Datenshi. He focuses fully on the target before beginning the jutsu. It starts first with a small spot of fiery pain in the target's chest, caused by a very dense, slowly igniting orb of Nurarihyon's brimstone concoction. The ring of heat quickly travels outward, gaining heat, and becomes a solid sphere of brimstone when it surround the target fully. From eight points on the sphere at the top, bottom, left, right, and diagonals, magma and brimstone is expulsed. The whirling conflagration turns even the most enduring opponents to statues of magma and brimstone.
