Luffy remembers how he was advised by his friends, how he was saved by his comrades, and the frustrations of being defeated. As Kaido mocks him to his face, the Color of the Supreme King Haki gushes out and they clash again.

A young Luffy who has been dreaming about getting out of Windmill Village one day to accomplish something great meets a young girl named Uta who came along with Shanks and the Red-Hair Pirates calling herself the musician of the pirate group.

Momonosuke and Shinobu face Kaido while Kid and Law challenge Big Mom. Meanwhile, Nami, heading towards the stage on the Performance Floor along with Usopp and Tama, hears a strange voice.

Nami strikes a thunder blast to clear the way to the stage on the Performance Floor. However, the elite corps of the Gifters shows up to crush their inferior opponents. Upset but unbroken, Otama stands up to give a command!

Hearing Otama’s command, the Gifters side with the samurai and upset the Tobi Roppo and others! Chopper starts to take care of Zoro while suffering from the side effect of the enhanced Rumble Ball. Meanwhile, Jimbei gets stunned by Who’s-Who’s story.

Who’s-Who expresses fierce resentment toward Luffy and Jimbei fights back out of his loyalty to Luffy. As Who’s-Who asks Jimbei a question, he tramples on the dignity of the Fish-Men and that sparks Jimbei’s outrage.

To cut ties with Kaido, Yamato unleashes his true power. Meanwhile, Queen repeatedly attacks Sanji with his power as a cyborg, and Sasaki in his Man-Beast Form launches tricky attacks on Franky and drives him into a corner.

In the dense mist, Brook is surprised to see his old friends, the Rumbar Pirates and Laboon. They reminisce about the old days and play music together, however, they suddenly attack Brook.

Dogstorm confronts his sworn enemy who destroyed his country. Meanwhile, Cat Viper faces Perospero who is responsible for Pedro’s death. At Tokage Port, Momonosuke roars with his determined eyes.

The battle between Kaidou and Yamato gets intense. Backed into a corner, Yamato remembers three great swordsmen who he met when he was a child. Their stunning choice for the future of the Land of Wano encourages Yamato.

Luffy amps up the reluctant Momonosuke, who is afraid of heights, in his giant pink dragon form, to fly and take him to Onigashima in the sky. Meanwhile, Yamato, in a hard battle against Kaido, vows to survive until Luffy returns.

Momonosuke faces Kaido once again trembling in fear. However, with Luffy’s encouragement, he bravely steps up and shows his dragon fangs remembering what he had to go through because of Kaido.

Yamato helps Momonosuke conquer his fear of flying and the two take on the most important task of saving Onigashima. Meanwhile, Luffy and Kaidou clash which parts the heavens. The clear skies help Inuarashi and Nekomamushi finally defeat their foes.

Realizing Onigashima’s impending threat, imperiling everyone’s life, Yamato and Momonosuke launch a secret operation. Meanwhile, Sanji and Zoro are both in a deadly battle against Queen and King.

Queen’s unforeseen move stuns everyone on the Performance Floor. And then, he goes on to utilize another special technique which can break every bone in Sanji’s body. On the verge of a crisis, Sanji feels something strange again.

Killer tries to figure out how to fight against Hawkins whose power enables him to transfer damage against him to Kid. Kid is dying not knowing where his damage is coming from. Killer takes a chance with Kid’s life on the line.

Sanji still wonders what is happening to his body as he receives attacks. Meanwhile, the dying Kin’emon hears an unexpected voice calling for the also dying Kanjuro. Through the Smail, the voice of Orochi tries to stir up Kanjuro to make him perform one last time.

Law and Kid are having a tough battle against a formidable Emperor of the Sea, Big Mom. However, when they decide to work collaboratively and use their awakened Devil Fruit powers, they see the possibility of taking down the old generation.

Sanji is tormented by the idea of becoming a cruel Germa warrior like his siblings and torn between being strong or being humane as he is now. When he makes up his mind, he asks Zoro the ultimate favor.

The chaos within the floating island of Onigashima rages on to seemingly no end. Kazenbo, Kajuro's creation, is wreaking havoc all throughout the Skull Dome in the name of vengence for the Kurozami. The rampage causes panic among Beasts Pirates and samurai, alike. As Orochi watches on, he hears a sound that reminds him of his past love.

Zoro is facing a hard fight against King who seems invincible. Even one of Zoro’s deadliest attacks doesn’t leave a scratch on him. On top of that, one of Zoro’s swords goes out of control and gets in his way.

Zoro still can’t gain control of Enma which keeps extracting his Haki. Backed into a corner by the formidable King, Zoro remembers the encounter with an old man in his hometown when he was a child.

Queen’s formidable attacks remind Sanji of his family. Annoyed by Queen’s provocations, Sanji remembers a young woman mysteriously getting hurt in front of him and realizes what happened at that time, which lights a fire within him.

Zoro tries to figure out a way to damage King. Meanwhile, King remembers when he first met his captain Kaido and declares that his captain is the one to become the King of the Pirates, which leads Zoro to set his swords alight with hellfire.

Usopp finds Kin’emon’s upper body and the heavily wounded Kiku. However, they are surrounded by the Gifters and can’t find a way out. Seeing the samurai giving up hope, Usopp remembers his determination.

In the Flower Capital, the Fire Festival is about to end. On Onigashima, the battle between Luffy and Kaido is getting even more intense. However, Kaido who is excited about having a strong opponent starts drinking too much.

With the ongoing battles in various parts of Onigashima, everyone is reaching their limits. In the face of Big Mom, Law and Kid are exhausted and deeply wounded. Mocking them, Big Mom tries to head for the rooftop.

Big Mom’s strong life force discourages Law and Kid. Law tells Kid that he only has enough energy for one last strike. However, a monster Big Mom summons puts the two in even more of a bind.

Kid’s all-out deadly attack and Law’s tactical action leave Big Mom in the lurch. Then she remembers what Roger said in the past and wonders if the treasure he mentioned is out there after all.

Kaido mourns Big Mom’s defeat and remembers the day he met her for the first time. Meanwhile, backed into a corner, Orochi sees the true nature of Komurasaki, the woman he loves, and trembles with fear.

On orders from the Five Elders, the CP-0 agent Guernica tries to get to Luffy, but Drake stands in his way. Meanwhile, Luffy who only has very little energy left uses his last Gear Four to emancipate the people of the Land of Wano from Kaido.

The battle between Luffy and Kaido comes to an unexpected end. Kaido comes down and tells everyone that Luffy has been defeated and the Land of Wano is finished. Momonosuke and Yamato argue over whether they should still continue fighting.

As Luffy's heart pounds in a funny way, the Five Elders reveal the secret behind the Gum-Gum Fruit. Meanwhile, Orochi tries to convince Komurasaki to escape with him, but when he sees Kanjuro, he makes a malicious decision.

Bouncing on the ground and becoming a giant, Luffy enjoys his new, bizarre power while Kaido is bewildered and can’t make sense of it. Meanwhile, Kid, Law, and Luffy’s other allies continue the fight down below against flames and enemies alike, waiting for Luffy to emerge victorious.

As Luffy and Kaidou continue their battle, Raizo and Jinbe utilize their plan to put out the fire that has spread throughout Onigashima. Meanwhile, Yamato warns Momonosuke of the danger Onigashima will face if he does not act soon to create new flame clouds to keep it from crashing into the Flower Capital.

Momonosuke struggles to create Flame Clouds to sustain Onigashima which is in free fall. In the Flower Capital, the Fire Festival is ending with people flying their Sky Boats in the air. To fulfill the promise to free the Land of Wano, Luffy inflates his fist to strike Kaido.

When Oden died 20 years ago, Orochi took over the Land of Wano. People were separated from their loved ones, forced into labor, and starved. Now they pray that Kaido will vanish as Luffy’s battle against him reaches a climax.

Kaido remembers how he was treated unfairly in the past and how he believes the world should be. While his friends struggle to survive on Onigashima, Luffy is asked by Kaido to picture his ideal world as he throws a destructive punch.

The samurai and the Straw Hats shout for joy as they hear that Luffy defeated Kaido. Meanwhile, Momonosuke informs Zunesha of a major decision that he made. However, when Yamato calls on the Animal Kingdom Pirates to stop fighting, the earth trembles.

The people of the Flower Capital get flustered when Kin’emon and the other Akazaya samurai who were supposed to be dead appear from the smoke. However, the last one who walks out of the smoke, and what he says, confuses the people even more.

The Land of Wano is in a celebratory mood now that the years of tyranny are over. However, Yamato is holding back his hunger alone until Hiyori arrives with the news he was waiting for. Meanwhile, some unknown figure approaches the Land of Wano. Momonosuke announces to the citizens his victory and the return of the Kozuki Family. Tama remembers her childhood, and Yamato asks to join Luffy's crew.

The news of the defeat of the Emperors of the Sea spreads across the world. Luffy enjoys the banquet but just as he is about to make a toast, an enraged Kid comes in to strike him. The reason behind his action surprises Luffy
