> Zoro hates being hit on his back , since he considers that a shame for a swordman :
> He even was on his back against Daz bones who doesn't give a shit about that analogy but Zoro still turned over to get slashed on his torso instead of his back .
> Now with Kaido being faster with his Thunder Bagua that even Future Sight Users found it troublesome :
> This is a better Version of Future Sight than the one that was used against Katakuri :
> This same Future Sight ( against katakuri ) couldn't help Luffy from getting One shotted :
> Now since we established how Fast Kaido is , let's talk about how Zoro was close to 0 stamina :
-> He was very injured after blocking Hakai :
-> He was at his limit that's why he prefered to end this for all by using his ultimate style Nine Sword Style Asura :
-> Zoro fell down and that was the best attack he could do in that condition :
-> He reached 0 stamina to the point he was struggling to even move
while he was lying on his torso :
-> Now with the full page , You can see Zoro lying on his torso with 0 stamina and struggling to even move with 30 bones broken ; Kaido got mad and ordered Law to stand back there and went on using his famous blitzing move Thunder Bagua and he hit Zoro and Law at the same time :
> As You can see Zoro was on lying his Torso but in that moment Kaido tried blitzing with a Bagua , he used his torso to get hit because of his ideology of getting hit on the back since it's a shame for swordmen .
So to get the point :
Zoro with 0 stamina turned over faster than Adv CoC Thunder Bagua so he wouldn't get hit in the back .
