Surpassing the Master

is episode 156 of the Naruto: Shippūden anime.

Synopsis
Naruto continues his training to master Sage Mode, but this time without any oil. In the meantime, Taka finds out that J has been following them and so they kill him. His partner reports this to the Fourth Raikage which he decides to send in a platoon to rescue Killer B, and also calls up on Team Samui. As the Kumo shinobi infiltrate the hideout, Taka is already gone, and all that is left is J's body. Then the Fourth Raikage gives Team Samui a message to Konohagakure to be given to the Hokage that Kumogakure will deal with Sasuke Uchiha and tells that he will hold a Five Kage Summit among the Five Great Kage Nations and screams "The Akatsuki will not be Forgiven!". Naruto then starts to practice more senjutsu.
