Summary

Trapped inside the visions Itachi planted, Naruto silently begs Sakura or Kakashi to pull him loose, and the pair of Sakura and Chiyo finally break the spell. Kakashi warns him to stay sharp and charges in. Itachi answers with the Phoenix Sage Fire Technique, which Kakashi slips past, then hurls a Great Fireball at the trio, who scatter clear of its path. When Kakashi swings his Lightning Cutter, Itachi leaps aloft to dodge, but Naruto tries to catch him mid-air with a Rasengan. On impact, the Itachi they have been fighting dissolves into a shadow clone.

Key Events

Kakashi blankets the area with the Hiding in Mist Technique he once copied from Zabuza, though Itachi dismisses it since his Sharingan pierces the haze. Sensing something amiss, Kakashi burrows underground for a decapitation ambush that Itachi evades, then seizes the ninja for a genjutsu, only to find he is gripping another shadow clone that now traps him instead. On Kakashi's cue, Naruto recalls Jiraiya urging him to fold his own chakra into the jutsu and forge a signature version. He rushes in with a shadow clone and drives his Big Ball Rasengan into Itachi and the clone alike.

Notes

Itachi flashes a smirk as the blast lands, and once the dust settles the body left behind belongs not to him but to Yura, an Anbu commander and jonin out of Sunagakure. In a parallel fight, Guy unleashes his Morning Peacock to shatter Kisame, yet the corpse revealed is a stranger wrapped in an Akatsuki cloak, a man Guy insists he has never laid eyes on. The installment adapts chapter 260 and premiered in Japan on May 24, 2007.
