…Not because of the mental strain so much as the physical one from keeping your arm up the entire time like Naruto and Bee are. Yamato gets to support his arm with his other one at the very least.
Anyway, this was probably the fastest chapter I ever recall reading. Granted, it was mostly cell after cell of action but it was Naruto versus the Nine-tails after all. That’s not exactly something you see every day. Also, what I was led to believe was going to be some sort of figurative chakra tug of war turned out to be an all out battle for shounen fanatics to enjoy. The best part is that their epic struggle is taking place in Naruto’s mind, meaning he doesn’t have to be concerned about his surroundings and can just go wreck havoc with all his biggest techniques. Sage-infused Rasengan, Rasen-shuriken, and the usual Kage Bunshin decoys. What’s there not to like?
Of course, shit had to hit the fan right when Naruto looked like he was winning, but out pops his mother Kushina to calm his heart. Now I can accept that these internal Naruto safety mechanisms were all implanted with chakra somehow to activate at the appropriate time (since we all know that it can do everything), but how the hell does anyone plan this far ahead? Minato’s one triggered once already to help reseal the Nine-tails, but now we have Kushina’s to help conquer it. Is this the equivalent of a will in the ninja world or something? I mean it was a nice shock and all, but rather convenient. Too convenient.
