Sasuke's Decision: Pushed to the Edge!.Gaara begins transforming into Shukaku, dramatically increasing his strength and speed. Sasuke uses his Chidori to slice Gaara's arm off, but the pain only makes Gaara more determined and excited to kill Sasuke. Unable to use the Chidori a third time, Sasuke is forced to use his cursed seal so that he can attack Gaara again. This fails to defeat him, and Sasuke collapses due to the use of the cursed seal. As Gaara prepares to inflict the finishing blow, Naruto repels the attack with a kick. Naruto, Sakura, and Pakkun arrive ready to help Sasuke.
