During the training with Fukasaku to dominate the Sennin Moodo, Naruto trained secretly at his new jutsu. Naruto made it to the name of jutsus (Fuuton: lawn Shuriken) to make all honor by having learned the Fuuton: Shuriken throwing lawn. As Naruto used the newly acquired natural energy, he created a Fuuton: lawn Shuriken that he as a Fuuma Shuriken at his opponent, threw Pain. This increased in size, as it had arrived at Pain. So he could do one of the bodies immediately and disconnect the female body from the remaining two. Thus, Naruto managed by the mastery of Sennin Moodo to make this already extremely serious Jutsu again to a new level by managed to throw it, and evidently also to strengthen again or to zoom. The downside, however, that he can apply it only 2x before it runs out the Naturchakra. The jutsu is classified as Kin-Jitsu, because it destroys the microscopic needle-like results in your own body cells, thus inflicting the user with too much damage.
