*spoilers* Naruto is the 7th Hokage and he is paired with Hinata & has 2 kids, a boy and girl. His son is just like a mini naughty him It's basically a happy ending.. but I'm not really that satisfied as I wished there would've been events that lead up to that.
The chapters before the last is Naruto vs. Sasuke. They both lose an arm, Sasuke admits defeat. etc. Though they both lost an arm, they regain it thanks to getting an artificial arm made by the first hokage's cell.
