For some reason, people wrongly assume that Naruto's TSB are YYR and that Kaguya doesn't have Senjutsu. If both were true, then Naruto would be able to negate all her attacks, yet he can't. So logical conclusions:
 * the reason why his supposed YYR can't negate her attacks is because she uses Senjutsu
 * he doesn't have YYR

Your pick.
