Besides the arm removal (which was thanks to Sasuke causing Kaguya to shift to a normal dimension with no gravity involved), what other time was Naruto able to blitz Kaguya? You mean when he punched her? Because; if so, then Sasuke helped Naruto as well. I'm not sure what you're trying to prove. Kind of sad, right? You're downplaying Sasuke here, because he was able to land a sneak attack against Naruto! I'm missing your point! So, Naruto could land a hit to Kaguya (i'm going by what you believe), but couldn't defend himself against Sasuke? A>B>C logic always when it comes to this series. Whether Sasuke was the main star in that fight, it's completely irrelevant. Sasuke made sure that Naruto was able to land some hits, regardless if you believe that's the case. (Why do you think Kaguya separated Naruto from Sasuke?) I think you know why.
