No not really, from the begining even before the scabbards ambushed Kaido Yamato was designed to fight Kaido
Yamato vs Jack as small scuffle? sure maybe
Yamato vs Jack as small scuffle? sure maybe
And yes, that is what I'm talking about, but not as a small scuffle, a hype fight that has them both go hybrid but Yamato wins. Hypes her hybrid before confronting Kaido. It's just a guess for now, I get that, but if Inu doesn't take out Jack by himself, who else is supposed to help him?
