Wind Release: Repeated Rasenshuriken

The Wind Release: Spiralling Serial Shuriken is a ninjutsu created and utilised by Naruto Uzumaki.

Usage
After activating Kurama Mode or Sage Mode (in the anime), Naruto is able to form two Rasenshuriken and wield both at the same time. Their cutting power is so extreme that by using one of them as a melee weapon, Naruto was able to cut through the Ten-Tails' extremely durable tails with ease.
