Just after Luffy used Red Roc on Kaido leaving him in shock and damaged him.. We can see Zoro's reaction
that he has no clue what that Haki is, but he knows Luffy learned it from Hyougoro..
And it's ok that Zoro doesn't know those Haki because CoA Swordsmanship is different than the CoA
Non Swordsmanship learning curve..
CoA Swordsmanship ∼ Regular CoA
CoA Imbuing ---|--- CoA Barrier
Base CoA Air Slash --|--- CoA Internal Destruction
Black CoA Beam ---|--- CoA Emission Blast(Koby)
Black Blades -----|---
There's are no CoA counterpart for Black Blades because they stand at the top of CoA Haki and that's why the
World Strongest Swordsman is big and important, Swordsmanship is the peak of CoA Haki..
Let the denial begin!..
