I just think it's weird that he releases an S rank ninjutsu without sweating? Naruto in the original work with senjutsu activated could only cast 2 times (elite level jonin with kurama chakra), still with high genin level? the story is good but the powers are unbalanced. But it's a matter of opinion. But I still give it 5 stars. Have a good day.
His chakra volume is already high, also with his high physical body that already break its limit. Naruto is only half uzumaki, while he got a good chakra volume, its not as good as full uzumaki, he got a huge volume mostly because kurama, where he is trying to control kurama chakra so it didnt intervere with his chakra, so he cant use it all. Also, chakra controll matter, you know naruto got the worst chakra control where he cant event make clone, so what didnt say that his control of his S jutsu sucks and can only do it with high chakra, maybe that is why he always only use rasengan and shadow clone, because he can master them
