-WIND RELEASE-
After failing to bring Sasuke back to Konoha, Naruto went through elemental training where he discovered that he had an affinity to wind, which by incorporating into the Rasengan, which was originally intended to be combined with a nature element, would greatly increase his power and his chances. The wind nature compliments a fighter like Naruto, as the wind nature is a good match with short ranged fighter. By focusing his wind chakra, Naruto can go as far as cut things with only his chakra. Naruto had learned nature transformations to upgrade his Rasengan, which he achieved with the Wind Release: Rasengan and the Rasenshuriken, combining both shape and nature manipulation originally deemed impossible without natural talent or instinct. The Rasenshuriken was capable of slicing into the victim and cutting them at a cellular level faster than a Sharingan can see it. It however caused similar damage to himself as it is still a handheld jutsu, despite it's name. After his sage training, he could throw the Rasenshuriken and expand it, increasing its power and attack radius.
