Naruto gives the reason he has a lot of chakra, it's because he's been getting the 9 tails chakra that leaks out his whole life. This is Naruto with 4 times Kakashi chakra.
Even in part 1 Kakashi confirms it's the 9 tails that makes his stamina (components of chakra) amazing and that time in the databook Kakashi has a 3 for stamina and Naruto a 4 which isn't much more than Kakashi while the 9 tails makes it that. Kakashi says his own is average in otherwords both satements together confirm the source of his chakra is the 9 tails.
The only one into fanfic is you stop making excuses alt account.
Ps. A little of the 9 tails chakra would still be a lot and if he's been receiving it his whole life we know why he has a lot (4 times Kakashi). This is off topic so I won't continue take your L alt account.
Did you really expect him to have a functioning rational faculty?
OT: She has rokudo resistant to TSB rods via Byakugou, She can resist Rokudo level genjutsu, her fist of solo hurt Kaguya. Now all she needs is to actually be developed and full full her potential at casting genjutsu which'll likely be rokudo tier.
