Woah, idk if anyone is seeing this, but it looks like 98, 99 and maybe 100 might be "themed" battle covers. Reason being is Kaido's random midsection in the volume. It could very possible that next volume is Luffy, the Strawhats, Law, Kid, Killer and Drake, while 100 is Kaido's head, Big Mom and the rest of the beast pirates (potentially others depending on what that volume covers)
