I'm a luffy,zoro ,yamato,Franky and sanji fan boi. But I don't believe zkk
I'am SHP fan and believe Luffy is stronger than Zoro, right now or after this manga finished.
But,......
I still believe Kaido's head will be chopped by a monster samurai in this arc..
The one who we always call him as; Roronoa Zoro, Zoro, Roronoa, Luffy Right Hand Man, SHP vice Captain, Pirate Hunter, Zowo, Zorojuro, Mosshead, Zori, Zolo, Lolonoa, etc
We dont need another Kaido's arc in the future. And he no need to exist in OP world too. This is because he said himself clearly, this world doesnt need two Dragons.
So, Kaido will die in this arc by the Monster Samurai which he looking for it long time ago
