Well Daz bones wasn’t a swordsman and King is a swordsman… So… Zoro wants to be the strongest swordsman doesn’t he
Marco knows a lot of shit about a lot of people… remember when he was fighting Big mom and he said “I unlike everyone here knows exactly how dangerous you can be”… And then we thought this means that Marco’s main thing will be Fighting big mom since apparently there’s some connection there… And then nothing happened
Again, it’s alright my guy, it’s very likely that all the strawhats are gonna end up on the roof given how easy these fights have been… Its very likely Zoro will end up fighting Kaido again… But KAIDO IS NOT A SWORDSMAN and Zoro WILL NOT leave the Arc about swordsmen without defeating the strongest one there
