Zoro doesn't need to kill Kaido to have some kind of development in the remainder of Wano. The main theme of Wano seems to be identity, so why not spend a couple chapters exploring the Shimotsuki connection? Wouldn't that fit in well with what this arc is about? Zoro's a swordsman, but there are ways to develop that outside of having him cut something (and imo it would be a lot better that way, cause we've already had multiple instances of Zoro just learning to cut better).
I said nothing about development, i'm talking about SHs doing their job
Do you expect Usopp to go to Sniper Island without proving himself as The Best there?
Or going to Elbaf without proving his Bravery to them?
Did you expect Sanji to go to Land of Food, Cooks & Food-Related DFs without proving his Cooking Skills?
Did you expect Jinbe to not show his resolve to end Racism in a Fishmen-Themed Arc that only talks about Racism?
Why do you people accept every single SH proving their Top Tier Skills & Roles when they are in Related-Themed Arc
But when it comes to Zoro, you refuse to imagine him proving his Swordsmanship to Swordsmen?
Wano People still haven't seen Zoro cutting anything
You think Oda would draw entire Dressrosa shocked at seeing Zoro cut Pica (Including Big Names like Chinjao & Kyros & Kin'emon ... etc)
But Land of Wano won't witness Zoro's Swordsmanship? Be realistic plz & stop the bias
You think Zoro's Last Cutting Feat is defeating Villain's Henchman without being seen by anyone even though that's something he does every single Arc?
I swear, if there was something worth cutting in Wano aside from Kaidou, i would have doubted ZKK
If there was like a Huge Meteor, another Monster, a Dragon Pet that Kaidou keeps or a Huge Ship ... etc
I would have considered the idea of Zoro's Cutting Feat being against that & not Kaidou
But Oda made it absolutely clear, there is nothing else worth Cutting in entire Wano Arc except Kaidou himself
And he supported it with dozens & dozens of connections, hints, foreshadowing & parallels
The kids of Wano were practicing Two-Sword Style because they thought of Orochi as their Hero
If you go check Cover Stories, you will find that Zoro's Village are now training only in Three-Sword Style
Do you think Wano will end without Kids wanting to learn Three-Sword Style similar to Zoro's Village which was founded by Shimotsuki?
