Luffy getting defeated is setting up for a “Fresh 100% Luffy vs Fresh 100% Kaido”
Later on and nothing else!
I think at this point... It’s clear what Oda will do... he will basically make Kaido’s words come true:
1- He announced he will lift Onigashima and move it to Wano (in process and will be checked soon)
2- He announced that Yamato will be its new Shogun (Yamato is headed there to get beaten badly, taken, then FORCED to play as a pawn Shogun on Kaido’s stead... (it will be around 2 weeks... cause add 2 weeks with 2 weeks and here is your Hawkins 1 month prediction for the arc)... In those two weeks, the alliance will recooperate, and get ready with a bigger force and allies from outside world.. and will get stronger...
3- Kaido said he will look for Ancient Weapons... and I predict that AT LEAST one will be obtained and used for that war...
so yeah.. that’s how I see it now
