Oda is really moving the story forward in this chapter. Now is only one day left before the raid on Onigashima and Act 2 comes to end.
Luffy finally learns how to use advanced Busoshoku Haki and Zoro gives Enma a test run, and it looks like it can do some serious damage. According to Robin, the enemy is already bigger in terms of numbers. Assuming that Kaido and Big Mom are still buddies, it's only going to get worse. Usopp, Nami, and Chopper are going to cry when they hear about the team up between the two Yonko. Luffy better be prepared to use Haoshoku Haki to thin out the enemy ranks. More bad news is that Orochi knows about the new meeting place and that Hiyori is alive. As for the prisoners in the capital, hopefully someone can free them.
Here's a thought. Tama should mix her dangos with the food that is going to Onigashima just like how Orochi mixed the failed SMILEs with the leftovers. Any Gifter who eats Tama's dangos will become allies. Hopefully, the minks will also be able to use their Sulong forms during the battle. Here's another thought. Since it would be extremely difficult (if not impossible) for Luffy to fight both Big Mom and Kaido, Luffy should fight either of them while Zoro fights the other one. If not, then what was the point of mentioning Enma having harmed Kaido?
Here are some more questions. Where are Jinbe, Nekomamushi, and Denjiro? Did Kid and Killer had any luck finding their crewmates?
Anyway, on to Act 3.
