man start to think logically please...
Greenbull went after an alliance that defeated both big mom and kaido combined...
He does not fear an alliance that defeated big mom and kaido combined...
It's apparent that fear/powerlevel is not the reason for why he would not come to wano if Kaido was still around.
And he doesn't want smoke with Shanks for similar reasons which are ties to the WG.
I am thinking logically; I'm just arguing against your stance.
Even that itself doesn't make sense when we hear this chapter that Aramaki doesn't want beef with someone like Kaido from begin with. It's illogical.
Again, like I said, either he completely underestimated them like "They're just brats who were lucky" or he was actually insane enough to attack a force which is >>> Kaido.
What is the reason then? He calls Momo a Kaido wannabe in contrast to his strength.
You really think he retreated because he knew Shanks is related to the WG? At least hope he'll state it, otherwise it's baseless.
