Nine Tails / Kurama.Episode 327 Nine Tails: Before revealing the method by which to stop him, Son verbally states his distrust of Naruto especially after Jinchuriki have mistreated him in the past. As Kurama listens to their dialogue, he relates to Son's distrust since he was also simply used and sealed by many ninja in the past. Losing himself in thought, Kurama recalls how he sought to weaken Minato's Eight-Trigram seal and hence free himself by influencing Naruto with his own chakra on many occasions. Eventually after experiencing many trials and battles, Naruto frees himself from his own hatred with Killer Bee's help and successfully takes control of the Nine-Tails chakra, leaving Kurama to ponder just what type of person Naruto actually is.
Episode 328 Kurama: With the battle receding at their end, Sakura Haruno and Shizune depart to assist Naruto and Bee. Elsewhere, Tobi realizes that Naruto is inside the Four-Tails and tries to absorb them both. Naruto is able to escape Son Goku's body by having him regurgitate due to his Multi-Shadow Clone Technique. Inside his subconscious, Son reveals to Naruto that the chakra rod is stuck at the base of his neck while in Tailed-Beast form and Naruto locates and starts pulling it out, with resistance from Tobi. Silently observing all that transpires, Kurama recalls Naruto's past achievements by his willingness to never give up and accepts that if Naruto truly wishes to help the Tailed-Beasts from the bottom of his heart, then as he always has, his actions would speak far louder than his words. Finally, Naruto uses a clone in Sage Mode he left inside Son's body to find the exact spot the rod is located in relation to its position outside and uses Frog Strike to successfully push the rod out of the Four-Tails.
