so
- Green Bull don't want smoke from Kaido
- Green Bull don't want smoke from Shanks
is it me or ... this is implys Yonko > Admiral ... almost ... maybe ... am I going too far?
And still, Aramaki has gone to Wano, where the ones that had killed Kaido
and BM are staying. Also, WB and BB have said or done similar things in the past. And Kizaru wanted to go and stop Kaido and BM, etc...
For the second, I suggest waiting for the raw. If Aramaki doesn't want to fight a new Yonkou + his unique crew, I think it's completely understandable. Or maybe the decision is based on something "unique" and valid only for Shanks, like a DC heritage (and Oda made it clear, maybe for that reason).
I don't know, maybe the next chapter will have some proof in the other direction or maybe this (full) chapter will have something new and completely revolutionary, but for now I don't see it.
