Spiral Shuriken

Spiral Shuriken(螺旋手裏剣, Kaitei Shuriken) is technique invented by Rasetsu Aragami, being the first ranged Ki technique that he ever created. It is similar to the Kienzan attack, though having several advantages and properties of its own that make it a very useful tool in combat.

Overview
The moment that The Spiral Shuriken makes contact with its targets body it immediately unleashes a huge amount of miniature needles into their bodies, destroying their nervous systems and ki pathways thus making it impossible for them to ever move again or even formulating ki for that matter.
