There's literally no reason to hold back in speed.
There's also no reason to go all out if she can match and overwhelm him without it.
She's trying not to get captured by them and at the same time trying to take Naruto chakra.
She was basically toying with them at that point and only started seeing them as a threat when Naruto outsmarted her for like the 3rd time.
Was she holding back strength at first? Yeah possibly and then she increased her strength when Naruto was still matching her. Idk where you're getting this blitz from.
She literally hits Naruto with 2 entire fists that he doesn't even remotely react to. What part of that implied a POWER increase over a SPEED increase? If we saw her blast Narutos fists out of the way or destroy them I'd understand a power increase but she just outright tagged him without him doing anything about it.
Either she outnumbered his fists or outsped his fists, there's no interpretation where this was the result of her increasing power.
Exclamation marks don't just indicate blitz. It also indicates discomfort by being thrown away. Naruto that was matching her blow for blow suddenly got blown away with so much force he kept doing summersaults endlessly in the air and couldn't stop himself that Sasuke had to and you attribute it to speed and not power?
Of course I attribute suddenly getting blitzed twice at once to speed. Wtf kind of logic are you using? Naruto saw her increase the power of her attacks so he decided not to block or dodge them all the sudden?
Also she does barely any damage despite 2 direct blows. If all she did to go from equal to Naruto to completely overpowering him and landing 2 blows is increase her strength then she should have done WAY more damage.
Idk if my imgur is lagged or what but the scan doesn't want to load for me.
You can see here clearly that they clashed multiple blows.
Yes while Naruto was like
RAAAAAAAAAHHHHHHH







While Kaguya was like
How do you look at that and interpret it as them putting in the same amount of effort…?
It's not something like one attack that you can maybe argue wasn't at her fastest but she's literally the aggressor, trying to steal his chakra, stop him from sealing her and yet you're arguing she decides to hold back speed to someone as dangerous as him and just decide to clash slowly severally.
Yeah Kaguya was like
"wow I'm try so hard rn

"
Also clearly the smirk she made was because while clashing with Naruto she still saw Sasuke with his susanoo above and figures out their plan. So she was probably thinking "these guys don't know who I am" then proceeds to increase her power and blow Naruto away..
She clearly smirked because of the susanoo? She looked like a disappointed parent when Sasukes susanoo actually appeared
This panel begs to differ. Unlike Sasuke zetsu just straight up admits Naruto is too fast for them to catch.
Naruto
1. Already saw exactly what Kaguya was going to do because she did it to Sasuke.
2. Has high level danger sense.
Again a 2x difference is NOT big and Naruto literally has precog to fight it as well.
The whole reason kaguya merged with her ice dimension was because she couldn't catch Naruto even with using her teleportation. You keep mentioning precog here but don't forget kaguya was most likely erasing her chakra signature but I digress.
Even if she was, does that negate danger sense tho?
I mean, we never saw or heard Naruto mention his danger senses are not working on none of the like 3+ Otsutsukis he fought so either they don't use it in combat or it doesn't negate danger sense.
Either way Naruto speed is notable enough to clash multiple times with her, too fast to be caught to the extent she had to merge with her dimension so as to find a way to pin him down and then come me out and try to catch him.
Under that interpretation Naruto is more than a blitz tier above both his clones and Sasuke. In that case it'd be something like
Naruto ~ Kaguya > fatigued Kaguya > Sasukes perfect susanoo > chidori amped Sasuke > Sasuke ~ 2r Madaras physical speed
Which I don't think is really supported by the narrative given that Naruto and Sasuke are mostly treated as equals and Kaguya is treated as basically unbeatable. But I don't really mind it since it works for my Naruto>Sasuke agenda


.
I'm just saying, under this interpretation it wouldn't contradict Kaguya being 2x as fast as Madara but prove Naruto is also 2x as fast as Madara.
