4th Hokage, (Naruto's father) reseals Nine-Tails and we see naruto regaining control over planetary devastation. naruto reverse-tracked the location of Nagato while killing (we hope) the last of Pains.
Sage Jutsu chakra can only be used 3 times. Once inside Bunta's mouth 2 Rasen Shuriken were used to kill one of Pain's Five. Gazer used Reversed Summoning Jutsu through scroll to recall two Naruto's clones gathering Sage Chakra.
naruto hits Pain with his Sage Jutsu-perfected Wind Style Rasen Shuriken. Although he succeeds in defeating Ningendo, the remaining Pain quickly confronts him.
