I mean I don't want to complain before the chapter is out, but what's actually the substance behind those last two chapters?
Sure, the action is nice and all, but if we're being honest, those two chapters didn't move the plot one bit.
We're still right were we were two chapters ago: The Supernova facing Kaido and BM on the rooftop, without anyone being injured.
Tbh, i think this is just for the spectacle, and to show the effort before this encounter reaches an unfortunate conclusion for the SN's.
I think Oda wants to end the Act with the Yonko apparently taking the big win and make it seem like everything is over, so for that to happen he's giving us these chapters that "give hope", since the SN's are shown mostly in a positive light, defending against Breath/Homie attacks, and throwing their moves at Kaido.
Also we obviously get a bit more build up with Kaido recognizing Luffy's potential, Zoro showing the fire cutting technique, build up with Enma, etc.
