Steel Release

The ninjutsu are created by combining two unknown chakra natures. To date, this form of nature manipulation has only been used by Hiruko, who obtained it using his Chimera Technique, in Naruto Shippūden 3: Inheritors of the Will of Fire.

Hiruko performs no named Steel Release techniques, but is able to use the Kekkei Genkai to make his body as hard a steel, causing it to become impervious to a variety attacks and weapons. Subscribe to inuyashastoryline on youtube
