Naruto: Shippuuden

Synopsis

Before revealing the method by which to stop him, Son verbally states his distrust of Naruto from his past experience with Jinchuriki. 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 the events of how he ended up in Naruto's body and of the numerous attempts he made to break free by weakening Minato's Eight-Trigram seal and influencing Naruto with his own chakra on many occasions. But following a series of 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.
