My prediction:
Chapter focuses on Momonosuke. At the beginning, we hear Momo's inner thoughts. He reminisces about the time he had with his father, mother and sister. Wishing he could go back to those days they were together. He also recalls the times he spent with allies, greats like Whitebeard, Roger, Luffy and co. He realises compared to his father and friends, he's turned out to be a failure. He knows he's still just a kid, but the weight and burden on his shoulders as the heir of the Kozuki clan and Shogun of Wano are too much to bear. He starts to realise his hopelessness. That Kaido is going to kill him, and his quest for vengeance will ultimately end in failure. As he internalises his final words...a few words come back to him. He hears Zoro's voice telling him:
"Sunacchi"
He recalls a flashback where him and Zoro are training. Zoro tells him if he ever reached the point where all hope was lost and that he couldn't see anyway out, to chant these words, it'll give Momo the courage to follow through.
...
Momonosuke ponders these words...
"Throw Away Your Name and Wits"
"SUNACCHI!!!!!"
Momonosuke transforms into a dragon breaking out of the cross. Everyone in the room is shocked.
