OMG who the hell cares if Ashura's is COC, or Advanced COC
If it's COC then it's a W for Zoro
If it's not COC then it's still a W for Zoro to be able to scar Kaidou with just normal COA
Either way, he still has COC. It's up-to-debate whether Ashura is COC or not, and I'm satisfied with both options.
