I think 3 sword style Hireyu Kaen is not for Kaido. It will be single sword style (Enma) that put Kaido to grave.
I really don't understand why Oda put Zoro sleep and at death door. Why not follow typical formula, where Zoro and Sanji have energy left to clean things up once Luffy beaten the main villian (like Alabasta and Enies Lobbies).
Why Zoro need to tank Hakai. Why not follow the same path as Killer?
This indicates that Oda want to keep Zoro for something... We will see...
Shimotsuki plot is left
he might become the Daimyo of Harumai or even Ringo or both as they comprise the North of wano but leaves because he is yet to become the WSS and making luffy the pirate king
might be his end of the story thing after the crew disbands and he comes from east blue
but Zkk.. no good reason left for it to happen.
Zoro proving something? nah the monster samurai things was done and dusted the moment zoro left a scar making him inevitably the next monster samurai that would meet Oden's mantle
Ryuma's legacy... again don't know why should it happen just for the sake of it given zoro's state atm and the fact that Kaido is KOed literally in his base form.
and suddenly he should be up and massacre people and zoro to just wake up out of no where and cut his head off bruh
i mean if oda knew people would hate Luffy defeating Kaido with just a physically stronger punch.. wouldn't he also know that zoro killing Kaido after an asspul recovery would be hated equally also given it has 0 basis story wise?
this theory has gone so far that people are literally contradicting the story to make it happen... like Nik said Zoro is carrying samurai's burden.. lol what? luffy literally had a moment on the roof dedicated to it.. zoro just exerted his frustration on Kaido the way he did and off he was from the roof for his king fight.
No theory makes sense atm.. zoro can kill Kaido but i think given there is no narrative buildup between him and kaido killing Kaido would be nothing personal between them.. doubt it gonna be a Ryuma parallel etc.. and that excluding double damage btw... so you see how slim the wire yall walking on is.
