"The Beginning of the Battle…!!" (闘いの始まり…!!, Tatakai no Hajimari…!!, Viz: The Battle Begins…!!) is chapter 181 of the original Naruto manga.
After gathering his things, Sasuke heads for Konoha's exit. He finds Sakura waiting for him there. He tells her to go home. She does not, instead asking why, after all they've been through together, he always ignores her. Sasuke responds that she can't understand him, but Sakura insists that, because she loves him, she's willing to try. She offers to help him take revenge and to accompany him in leaving Konoha, anything so long as she can be with him. He leaves so she threatens to scream. He knocks her out after thanking her. The Sound Four greet Sasuke outside the village to accompany him to Orochimaru.
