It is time for Naruto to face Sasuke. Kakashi would like to prevent him from risking his life, in vain. Until now, Naruto has been tormented by the choice of killing or sparing Sasuke. But now, his decision is made. However, their fight doesn't even get the chance to start; Madara and Zetsu interrupt their altercation.
Before he escapes with his accomplices, Naruto promises Sasuke a fight from which neither will walk away alive.
