"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 intensifies. Guy brings out his nunchaku to compensate for Kisame's Samehada sword, but is unable to land a strike. Kisame uses his Water Release: Water Shark Bullet Technique to force Guy underwater, and follows up with his Water Release: Five Feeding Sharks technique. Guy uses his taijutsu to attack all five sharks, but the sharks use the water to regenerate from their injuries. As his team is reaching the end of their line in their water prison and unable to take down Kisame himself, Guy resorts to using the Eight Gates. Opening the first six gates, Guy is able to stand on the ocean floor, recover from his wounds and send all the water flying upwards. Neji uses the opportunity to emit chakra from his body, breaking out of his water prison. He then uses Eight Trigrams Sixty-Four Palms on the three Kisame water clones, freeing his team. Guy assumes his Morning Peacock stance, ready to defeat Kisame.
Meanwhile, Naruto realises that he's in a genjutsu that Itachi cast upon him when the various Itachi he strikes transform into crows. Naruto wonders how Itachi trapped him in a genjutsu when he did not even look at his eyes, and Itachi states that he can cast genjutsu with his ring, which Naruto looked at. Itachi then prepares to put Naruto to sleep. Remembering Jiraiya's training regarding how to break out of a genjutsu, Naruto dispels the crows Itachi conjures, causing Itachi to remark that Naruto has grown.
