Sasuke's Rinnegan…!!

Summary
When Madara attacks, Naruto and Sasuke both avoid the threat with the legendary Uchiha noticing Sasuke's power. Naruto goes on the offensive but is somehow stopped by an invisible force, that Sasuke calls "another Madara". The young Uchiha proceeds to study Madara's jutsu while his clansman decides to take Sasuke's left eye for himself, but gets pierced in the chest understanding Sasuke's new ability. Sasuke and Naruto prepare a strategy to take care of the visible and invisible one respectively, and try to attack the Ten-Tails' jinchūriki with the power of Hagoromo, but Madara leaves behind his "shadow" and goes to Kakashi's side to take his left eye and go to Kamui's dimension right when Sasuke cuts him in half and Obito tells Sakura to destroy his Rinnegan before Black Zetsu could take over.
