Asura is great and that. But...
Isn't this part basically kills the possibility of ZKK?
Zoro acting like he is the initiator of the fight. Doing first blood and all. But the way he talks is as if he won't see the fight until it ends.
No it doesn't.
My ZKK theory goes that Luffy will be tricked into caring about someone, either Law or Kin'emon being captured / taken hostage by Jack or Big Mom, just like Oden was tricked about caring for Momo during his fight against Kaido.
In that fight, Oden didn't have any help, so Kaido got him on the back.
This time around, Zoro could recover and be there the final moment Luffy needs him, Luffy goes to save Law or Kin'emon and while Kaido goes to hit Luffy from the back, Zoro goes for the final cut on Kaido.
It works like perfection, because it's a parallel with Oden AND, the my biggest reason for why i say this theory, that's how Zoro's introduction arc ended, Luffy defeated Morgan, but Helmeppo took Koby as hostage, in that moment Luffy went to save Koby and trusted Zoro to give Morgan the final blow.
So that way, Luffy gets to defeat Kaido and Zoro gets ZKK.
