vergo didnt even use haki
he broke sanjis leg with sanjis fighting style
if vergo went full power sanji would be dead
o lord.
how can you infer he wasn't using haki?
if he wasn't then how can you infer sanji was using haki..
if we assume that both were using haki and sanji broke his leg..
in a similar instance where DJ sanji (faster kick speed and initial sky walk momentum) clashed with doffy, who is hyped to have better arnament, and didn't break his leg
even here you can't prove if either one are using arnament or not.. depends on fair assumptions that they did or did not.. since i mention Vergo and sanji did, I'll consider this to be the case here as well .. but the point is it was a kick way more potent than Vergo's that got him commended by doffy..and he didn't break his leg or hurt him after he clashed.
this further corroborates to the fact, which was even emphasized before hand, that sanji's physical state was worn and weakend.
you can always trivialize the moment and defy the narrative and even be dismissive about sanji still keeping up in the state he was in.
How was he weakened?
for the people arguing "OMG USSOP SURVIVED IT BUT SANJI'S BODY GOT DAMAGED"
thats a very dimwitted argument to make when we know pre TS ussop got clubbed with a 4ton bat to the face and he survived
He has extreme endurance and least durability and you can clearly see NAMI IS ALRIGHT while ussop is writhing in agony like he always does....no one in Alabasta took a 4 Ton move to the face... don't wonder why ussop survived that blast he survived it coz he is an endurance beast.. stop with the ussop slander...
so what actually wore and damage his body?
when an animal and a woman takes turns using your body and damaging it consistently and recuperating by behaving like they do in their body... you fuggin bet there would be consequences... hence why the blast taken by nami is sanji's body... was less painful to her and but when sanji switches all the agony relapses on sanji.
pure logic... you can always call it a headcanon by assuming you can't process logic.
Dont be ridiculously negligent in equity or don't argue at all.
