The Secret Weapon is Called....

Itachi uses shuriken inside the crows to immobilize Naruto, but Chiyo and Sakura free Naruto from Itachi's Illusionary Technique. Naruto and Kakashi together defeats Itachi who turns out to be Yura (a jonin-level ninja from the Hidden Sand) Chiyo wonders what kind of dark and powerful jutsu is this which allows all the abilities and powers to be transferred to an entirely different person. Furious, Guy opens his sixth Inner Gate and gaining much power ruthlessly attacks and kills Kisame who is later identified as Mukade (yet another jonin-level ninja from the Hidden Sand), stating the same case as Team Kakashi. They learn that Itachi and Kisame used the two ninjas to create clones to distract them.
