They team up and go wild on Juubi and obito and Madara. They defeat the Juubi. The Alliance plans on arresting Saskue but Naruto allows him to leave since he helped them. Saskue leaves after the battle telling Naruto to prepare for their upcoming battle telling him when he plans on attacking Konoha after he heals.
Naruto goes back to Konoha and becomes Hokage since Tsunade most likely died. A few months pass and Naruto and Hinata get into a serious relationship. It finally comes time for Saskue to proceed with his attack. Saskue and Naruto meet at the valley of end and have an epic battle. Naruto and Saskue fight until they finally hit each other with a Finisher and they both are severly injured and are dying
. Sakura arrives and begins to cry and talks to both of and expresses her love for both of them. Naruto tells Sakura that Hinata is pregnant and asks Sakura to help Hinata. Saskue and Naruto lay next to each other thinking about the past as they r both dying.
Saskue askes Naruto to forgive him for all the pain he caused naruto, AAnd Naruto asks Saskue to Forgive him for not saving him. They both die together and it shows 9 months later Hinata giving birth and A new Series starts with Naruto's Son , Naruto jr. as the new Sage of Six paths ( Since he has Senju lineage from Naruto and Uchiha lineage from Hinata) THE END hope you liked it
