The SFX in both panels is “Clang” so there is in fact an impact happening here
But what the hell is going on? Hyouzo’s swords get cut in half and Kaido somehow fails to do amy damage here
What is happening? Is Oda just a bad artist? Then why did he repeat this very specific panel if the first time was a mistake.
This panel seems to imply that both Hyouzo and Yonko fuckin Kaido tried to hit Zoro amd clashed with some kind of metal surface and FAILED to do jack shit to him.
