I know, I never doubted one bit.
The ZKK is not just cutting a dragon, is all the narrative about the samurai, the legend in Wano, the fact that Kaido hasnt confirmed yet that there is a monstrous samurai in Wano, the fact that Enma didnt get a proper closure, the fact that Kaido aint defeat until his head is severed.
Zoro vs King was a very good preparation to what will come next.
the editors said clearly that now is it possible to finish a dragon with 1 single swing
