Trailer

All of the New Fishman Pirates lie down defeated while the Straw Hat Pirates are relaxing and waiting for Luffy. All the citizens of Fishman Island are cheering for him to destroy Noah and thus saving them. While some citizens evacuate the island, some recall how Whitebeard also saved the island at a point in the past and how Luffy reminds them of him. Luffy keeps attacking Noah intent on destroying it while Neptune laments being unable to keep the promise with Joy Boy stating there is no choice but to destroy it. As Luffy continues to destroy the Noah, Shirahoshi jumps in front of him telling him to stop which he eventually does. He realizes that Noah has been brought to a halt by Sea Kings. However, he suddenly faints, falling back down to the Noah. The Sea Kings acknowledge the strength of Luffy's will. After everyone understands that Noah has been stopped, they start celebrating.
