This is how Naruto ends:
The other ninja folk find Sasuke and Naruto passed out, both almost dead from blood loss. Emergency operations commence. When they come to, each ask where the other is (this is done by a beautiful two panel page, where one half is Naruto's face and the other half is Sasuke's face, coming together as if they are one person. This is important foreshadowing so REMEMBER IT!).
Lo and behold, both Naruto and Sasuke have new arms (this has sadly been spoiled by the promo teasers for The End. Thanks Kishi / Obama). However, twist! Because it was all still fleshly spongy gunk, Saskue's new arm is made of parts from Naruto's arm, and vice versa.
Sasuke and Naruto finally remeet after their epic conclusive fight. "So, I hear my arm is your arm," Naruto says to Sasuke.
Sasuke smiles a happy smile - the first one in his entire life. "And my arm is your arm." The smile stays strong. they briefly look at each other. "We will always be together." Sasuke pats Naruto on the back with NARUTO'S ARM! "Believe it!"
NO OTHER CHARACTERS APPEAR
Time skip! There's a new Hokage. Is it Naruto? Sasuke? Yes. It's both. Joint Hokages! The team that never quits has still not quit, and now the dynamic duo of Team 7 has become Hokage.
Final page of the manga is a montage of them doing Hokage things.
Second to last panel, Naruto and Sasuke wrap their arms around each other ("Kishi, this symbolism is brilliant" they'll say", and walk into the sunset. The final panel, Hinata looks at the two walking away. She sighs.
