No idea.
@ Kaguya vs Sasuke vs Naruto
Naruto only reacted to her the third time, having no clue the previous two times, just like Sasuke. Don't know what's even the issue here, but people just cannot stop *****ing. Not to mention he failed to hit Madara, whilst Sasuke did so. So no, his body flicker isn't fatser by any canon manga logic.
Sasuke couldn't Chidori her because of the gravity field, given the stance that is specifically required for it. She was still sitting down. It's petty as **** how people make stuff up here.
