Naruto 699 and naruto 700 has unlimited access to his bijuu chakra, something that Sasuke does not have.
And I remember that what's been said about rinnegan is that the user can master all elements, not all ninjutsu. And is through training, rinnegan can't copy jutsu.
Naruto's power that is truly limitless, as he showed that the more natural energy he absorbs, the stronger he gets. The final chapters of both Soul Eater and Deadman Wonderland were no longer than an average chapter in the series. Reborn's final chapter was only 1-2 pages longer than usual. We'll just have to wait and see.
Also keep in mind that these chapters still have to fit into the series volumes too, at least I would think so. Don't really know if the volumes have a page/size limit like the magazines do which would allow a 'double chapter'.
Two things are possible Naruto solutions to escape the latest problem he had.
If we will observe, the Naruto that is standing/sitting right there had no buises, thus he is not the real one that fought Sasuke, this is the first and most likely solution, a Kage Bunshin. Why? Beaucse this is Naruto's signature jutsu since he started training in the academy. And for the sake of facts, his clones are proven durable and strong during the war arc, during his fight with Madara and with his fight with Kaguya.
The 2nd solution is Naruto using FTG, why and how? During his fight with Kaguya where a Nardo clone went inside the center dimension, it was very clear that the clone said " I already Marked the Place." so What Mark? No other than the tags which Minato uses when using Hiraishin. as the development has been going i could give a shit with whom naruto ends up, hinata can go out with kiba or any other guy for what i care
as for who will be hokage ad whats gonna happen to the villages that really is what i am looking for, although narutos design looks kind of odd, for someone to be an uzumaki he really looks worn out and he is just in his twenties, must be due to the ing pasta he eats everyday, i really hate for gluten and soy derivates to be everywhere in everyfood we eat.
Naruto did more during the war because he had a higher chakra capacity. Sasuke did just as much as Naruto, if you factor in his lesser chakra capcity. They were equally worn out imo. Every S/T jutsu sucked away a huge amount of Sasuke's, and we all know his chakra regen rate is equally below Naruto's, if not even worse than capacity. You're comparing marathon running and sprinting.
