Short Summary
10 days ago, Sanji's group forces Caesar to neutralize his poisonous gas, defeating Jack's subordinates and drive them off the island. They tend to the wounded minkmen, saving their lives and earning their gratitude.

Back to the present, the Straw Hats, Wanda, and Carrot head to Nekomamushi, while part of the crew informs the rest of the crew what happened to Sanji and Caesar. Just two days ago, a more serious event took place after Jack attacked, and because of it, Sanji may not be able to return to the Straw Hats after leaving Zou, since it is a phantom island that is constantly moving. Yet, the Big Mom Pirates caught wind of their crew's trail and followed them to Zou, of which Pekoms is a native.
