Fire Style: Armor of Ash Particles

Armor of Ash Particles (lit. アッシュ粒子の鎧 "Kaibunryūshi no Yoroi") Covering the entire body of this technique's user is an armor of ash which blends in with their body. Because ash cannot be burnt further than it already is, this jutsu protects an individual from being harmed by Katon, negating fire that may be seeking to burn a person. It requires no seals and can be applied to a target on touch.
