Half the shit this arc has been shown off screen, including the openings parts of the fight against Big Mom.
Do you actually think for a second that Zoro getting injured somehow takes priority over the defeat of one of the main antagonists in the series?
Holy shit ALL the Strawhats saw how poorly the people of Wano lived.
You could do this shit with literally every character.
Sanji saved Kinemon in Punk Hazard, cooked food for Momo, saved Toko, helped save Momo, and saved some geisha.
So does that mean Sanji has some kind of "deep connection" to Wano?
I don't hate Zoro fans. I have a brain.
All the "evidence" supporting ZKK is cherry picked moments that are misconstrued to support a delusional theory.
It does not matter if people saw Zoro cut King. In Monsters, Ryuma cut the dragon while the town was completely deserted and only a single girl saw it happen.
If Yamato is not strong enough to kill Kaido, than neither is Zoro. But that aside, Yamato beating Kaido is more likely because
A. Yamato is the next Strawhat
B. Kaido is her father
Kaido is a devil fruit user. All he has to do to kill himself is to jump in the water. The reason he hasn't done this is that he wants his death to be glorious.
That was the point of him cutting King's Dragon
