Few things to note since all the pages came out:
Ryokugyu hasn't used his sword yet, and it still remains to be seen whether he actually has a black blade or not–I personally don't think so. I think the fight will eventually come down to "Yamato vs Greenbull," I think Greenbull will eventually take the scabbards out mid diff. The scabbards are still healing, they are not at their full health, plus Asura is dead and the Minks can't use Sulong cuz there's no moon around this time. Momo is irrelevant, so the fight will eventually come down to Yamato vs Greenbull! I think that Greenbull will use his blade against Yamato, and will go all out against her, and I think the battle will end with her knocking Ryokugyu out off Wano. I don't see Greenbull fighting against Luffy at this point, it's pointless, it will drag out the Wano arc even more, plus we already had a big battle against Kaido, I don't see Oda going for another big 1v1 top tier fight, it's not in Oda's style to have another big Luffy vs Villain at the end of an arc where the major villain has been already defeated. Plus, let's be honest, Luffy is too strong for Ryokugyu, so I think it will end here. Since Sabo hasn't been captured and Ryokugyu has nothing against Luffy to blackmail him, I kind of don't see Greenbull's purpose in meeting Luffy, maybe if Oda wants it to. But from what I've got from this chapter, is that Momo and Yamato don't want to disturb the Wano people and the Strowhats, and I think narratively that's what's gonna happen. I think Yamato will short of scare off the Marines with their already predisposed fear of the Wano samurai, plus I believe Yamato will declare Wano as Luffy's territory and that will scare the Marines off of that country. I still don't know how will Ryokugyu terraform Wano, there's possibility that he will fall in love with Yamato, considering his personality traits, but the fuck knows.
