|Literal English||Steel Release|
The Steel Release (鋼遁, Kōton) is an advanced nature kekkei genkai that can be used to make one's body virtually indestructible by turning it into black steel. The elements combined to create this nature are unknown.
This Kekkei Genkai allows the user them to generate almost unlimited amounts of black steel by shaping their chakra into steel, infusing it into their body, granting them the ability to change parts of their body (or the entirety of it) into steel, which can be shaped in a number of forms for different purposes, and to produce steel objects.
The Kekkei Genkai relies around the use of steel for both offense and defense, with the users being capable of creating a wide array of weapons from their body to attack the opponents both in melee and from a distance, and to cover their bodies with steel in order to dramatically increase their defensive power, at the same time greatly boosting their offense as well.
