Lmfao checkmate.
If sword skill has NOTHING to do with haki why did the 2 teachers of zoro who taught him in their words swordsmanship and the way of the sword ONLY teach him haki or the concepts of haki ?
Teaches swordsmanship = actual lesson is ryou haki
Teaches the way of the sword
Actual lesson is haki only
So according to 2 teachers including the wss
Swordsmanship is haki and the way of the sword is haki.
I own you.
