wha? a non troll post by op?
Did someone steal your account?
I kinda agree, but at the same time i dont.
That sword was PS sword, naruto had nothing to do with the breaking of that sword.
Only narutofanboys would claim so, there greed they arnt satsfyied that there main character cannot be killed and has everything given to him.
so now they want a piece of wat sasuke did
It was teamwork, and I think every rational being inside narutobase agree with this statement.
What broke the Ame-no-nuboko was not the sword, it was Sasuke's Susano'o powered by Kurama's Shroud. Susano + Kyuubi was the feature Madara did in the past after all, even Sasuke stated this, in this chapter, so it is manga fact.
Another thing to consider, is that Obito stated explicitely that sword was a Sword of the Soul, ergo, it was powered by the will of the wielder (or the sage as Obito claims to be). So the reason behind the breaking of that sword is nothing more Sasuke and Naruto's will being stronger than Obito's will.
Naruto took a very special place on this part since it was both Obito and Naruto the ones who got the spotlight in the struggle before the clashing... what did happen, I don't know... it seems like Obito suffered damage, but what about Naruto's being damaged as well? This was not explicited yet, we have to see what happened.
Kishimoto wouldn't waste pages effortlessly on Naruto if Sasuke was the only one doing the things out there, so try to think more rationally before stating fanboying-lined claims...
Unless of course you were trolling just for fun.
