Naruto's Growth (ナルトの成長, Naruto no Seichō) is episode 14 of the Naruto: Shippūden anime.
The battle between Guy and Kisame intensified. Guy brought out his nunchaku to compensate for Kisame's Samehada sword, but took a beating from Kisame's Water Release technique. After being submerged by Kisame's attacks, Guy resorted to opening up six of his Eight Gates, and defeated Kisame with the Morning Peacock technique. Meanwhile, Naruto realised that he was caught in a genjutsu that Itachi had cast upon him, and recalled his training with Jiraiya to try to dispel Itachi's illusion on his own.
