Steel Release (鋼遁 Kōton) is a rare Kekkei Genkai that originates from Iwakagure in which the user is able to use both Earth and Fire natures to produce hardened metal-like structures from either his body or earthen sources nearby or imbue his body with the characteristics of a hard metal. Although there are other elements that use the same basic elements, Steel release works in an unique way. Using the Earth nature as a source and Fire nature as a manipulation, the user is able to manipulate and mold earth into a much harder substance, much like a blacksmith does when he uses fire to mold metal ores into refined metals.
