Synopsis
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 Style Jutsu. After being submerged by Kisame's attacks, Guy resorted to opening up six of his Inner Gates, and defeated Kisame with the Morning Peacock technique. Meanwhile, Naruto realized 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.
