Your question is you taking a shot at me and my question is serious, so don’t avoid mine.
I’m not taking any shot at you. I just want to understand where your POV come from, especially if you read all of Wano chapters.
Now to answer your question:
-One Piece magazine 5: we are told that the legend of the slaying dragon will happen again thanks to the second coming of Ryuma
-It seems to me that it is obvious that Zoro is the second coming of Ryuma
-At the beginning of Wano, Zoro was introduce as Ronin. Ronin are samurai without master
-Yasuei Shimotsuki fell for Zoro
-Thanks to the SBS we know that the guy who made the Wado Ichimonji, Zoro’s master and Zoro’s home village are all linked to Kozaburo Shimotsuki
-We learn that Enma was forged by Kozaburo Shimotsuki
-Zoro trained Momonosuke like Oden trained his son. He even taught him a Wano’s ancient slang
-Zoro saved Oden’s daughter
-One pièce Magazine 6: we learn that every blade that Zoro ever possess are from Wano
-We learn that in Wano a sword is consider to have the will of his wielder even after his death therefore Enma wield Oden’s will
-Oden’s will is to open Wano’s borders
-Zoro is the only guy who were able to tame Enma since Oden. Which means that Zoro is actually wielding Oden’s will to re-open Wano borders
-The biggest obstacle to re-open Wano borders is Kaido.
-Kaido said that there will never be a samurai as strong as Oden. He also said that only a samurai as strong Oden could re-open his wound.
-We know that Zoro have at least the same level of Ryou than Oden and it was hinted to us that Zoro will do better than Oden Ryou
-wise
Now if after all those elements, you still genuinely think that Zoro will not be a part of the Kaido’s fight, so be it.
