Had no problem getting up though. He was just knocked back. White eyes? So? King had white eyes after Shishisonson too, despite it doing no damage. You see the scabbards right before Kaido, wanting to attack him again, yet Kaido immediately bounced back and called their attack too shallow.
Same Kaido took 1000 times more damage. Why are you comparing this to Kizaru admitting he can't get up
