Summary:
Chopper discovers that heat can be used to slow the spread of the Ice Oni virus. Zoro defeats Apoo and obtains the antidote sample. However, Kaidou defeats the nine red pods on the roof.
Law defeats the guards and finds the Poneglyph. Remembering Corazon’s sacrifice and the mysterious initial D in his name, he wonders why he lives the colorful life he does.
Back inside the castle, Chopper, who has contracted the Ice Oni virus, attempts to suppress the symptoms by slowing down the freezing. Brook uses a torch to keep Chopper’s body warm and this prevents the virus from spreading to the rest of his body. Just then, Big Mom appears, riding both Prometheus and Zeus.
In the corridors, Kid runs through the corridors, but runs into the Poker user SMILE’s rattlesnake. Kid decides not to finish the poker game and get over it.
On the roof, the Nine Red Sheaths jump at Kaidou and stab him, but Kaidou fires a bolt of lightning that knocks them all back. Although the samurai prepare a counterattack, Kaidou brutally beats them all with a club, leaving them badly injured on the ground. Kaidou ends up breaking the roof with his punches, and Kiku’s severed arm falls to the living floor below, which Zoro finds. Big Mom decides to ride out and join Kaido on the roof.
Zoro becomes enraged at the queen’s lack of empathy for sick people. He walks up to Apo and uses the drag technique to slash him. He then obtains the antidote sample and entrusts it to Chopper before moving to another area. Chopper reports his findings to the crowd and works to create a cure for the virus.
Luffy, Sanji, and Jinbe run up the stairs on their way to the roof, but Sanji hears the voice of a harassed woman.
The anime adds the following:
Zoro and Drake are still chasing Apoa for the antidote.
The moment Kid and Killer run into Poker is shown. Poker tries to attack Kid, but Kid just punches him in the stomach. In the manga, it was just mentioned that Kid managed to win over the poker group.
The moment Chopper figures out how to cure the Ice Oni virus is shown.
Zoro took down several Ice Oni infected samurai before defeating Apoo with Shishi Sonson.
The anime expands on the following:
Pochev’s last fight against Kaidou and Kaidou overpowered them easily.
It was unclear in the manga when Law’s flashback (as he told Robin his full name earlier) took place. The anime shows that it took place in Wano.
