Wind Release: Rasenshuriken

Fuuton • Rasen Shuriken is a Ninjutsu technique utilizing the Wind Element. Rasen Shuriken was developed by Uzumaki Naruto out of the original Fuuton • Rasengan. This spiraling Wind attack has only been seen in a half completed state. But even in this incomplete form, it has wrought massive destruction. With the aid of clones Naruto will form Rasengan and add the Wind Element. Though called "shuriken" the attack is not thrown. The trick name along with the aid of clones who act as a feint allow Naruto to get in close and strike his opponent. The attack itself can only be maintained in his hands for a few seconds time.

Rasen Shuriken is formed by enumerable miniscule small blades which slice into every cell of his target, severing the chakra circulatory channels connecting all the vital points on the body. Once it connects the highly dangerous attack will envelop the target in a massive sphere of destruction. The attack hits the opponent in such a way that it is even beyond the abilities of the Sharingan to copy. Due to its channel severing nature, the result on the body resembles a fast acting poison more than an outright attack. Unfortunately this same damage is done to Naruto's arm. For that reason Tsunade declared it forbidden.
