One Piece - Season 23 / Year 2021

The resolution that passed the Reverie and the incidents surrounding the conference stun people all over the world and corner the Seven Warlords of the Sea. Meanwhile, a Navy captain Koby secretly contacts someone who is currently in the Land of Wano.

Admiral Issho and Fleet Admiral Sakazuki argue over the abolition of the Seven Warlord system and the alliance of the two Emperors of the Sea. Meanwhile, ex-Fleet Admiral Sengoku teaches the young Navy soldiers about the legendary Rocks Pirates that Kaido and Big Mom once belonged to along with all the other big names.

On the day of the Fire Festival, Orochi leaves the mainland of the Land of Wano heading for Onigashima where a big banquet will take place. Meanwhile, at Tokage Port, the rendezvous point for the rebel group, Kin'emon and the others are stunned by the fact that none of their allies are there.

The night before the great battle, Orochi orders the destruction of the Sunny along with some bridges across the country to block Akazaya samurai's allies from their rendezvous. Disappointed, the group of samurai still sets out for Onigashima with the memory of their beloved lord, Oden, in their hearts. However, 41 years ago, Oden was not respected by everyone.

When the angry mountain god, the giant boar, almost kills Kin'emon, Oden steps in. Kin'emon is impressed when he sees Oden's strength and pledges his life to serve him. Disavowed by his father, Oden decides to go on a journey around the country and gathers more followers along the way.

Oden transforms the wild land of Kuri into a habitable region and is made Daimyo over it. Then he meets Kawamatsu the Kappa and the two Minks, Dogstorm and Cat Viper, who become his followers like the others. Kin'emon and the other vassals are scolded by Yasuie when they try to steal money from him, and they begin reforming themselves for their lord Oden.

Whitebeard and his crew dock at one of the ports in the Land of Wano with their broken ship and the news excites Oden. He runs to the port and asks Whitebeard to let him get on board the ship but the request is rejected. When the ship's repairs are complete, Whitebeard tries to sneak out of the country, but he finds Oden tagging along.
 

Oden rescues Toki from the slavers and befriends her. She wants to travel to Wano, which unfortunately displeases him. With the appearance of Whitebeard on the coast, the course of their journey changes.

While Oden is still traveling the world with Whitebeard, his father's health is increasingly deteriorating. Orochi is to fill in as shogun until Oden's return.

The Roger Pirates against the Whitebeard Pirates! Their battle extends over three days and nights. Which crew will emerge victorious?

Roger's joint adventure with Oden continues. They travel to Sky Island, Water 7 and also Fish Man Island in search of the Porneglyph.

After Roger and his crew have inspected all the Road Poneglyphs, they set off for the last island. What awaits them there leaves them speechless.

After the Roger Pirates have been on Laugh Tale, they decide to disband. Captain Roger is the first man to disembark. After that, his remaining crew takes Oden back to Wano.

Oden learns that Orochi is tyrannizing Wano as the new shogun. When he hears that Toki has been injured in an attack on Momonosuke, he rushes to the capital to attack Orochi.

Oden keeps dancing naked in the Flower Capital and losing all the trust of the people. His vassals wonder why he is doing this. One day, Orochi comes to Kuri and reveals his evil plan for the Land of Wano.

It comes to the decisive battle between Kaido's army and Oden and his samurais. How will the battle end? What card does Kaido have up his sleeve against Oden?

Oden proposes a bet to Kaido and Orochi. If he and his vassals manage to survive in the cauldron for a certain amount of time, they must release them. Kaido and Orochi accept his proposal.

Oden and his vassals must endure one hour in the cauldron of boiling oil. If they succeed, they will be free. However, Orochi is already forging the next devious plan.
