After leaving Egghead, the Straw Hats and the Giant Pirate Crew celebrate their reunion with a big banquet.

Nami awakens to find herself in a completely unfamiliar place. Giant creatures attack one after another, driving her into a corner. At that moment, she hears a voice calling her name.

Luffy and the others come across a warrior riding a grasshopper.

Pursued by the Sun God, the Straw Hats flee across Block Kingdom at full speed. Amidst the chaos, the Sun God's true objective begins to surface. But as they run, another wall blocks their path. Their breakthrough rests on Luffy’s fists.

Leaving the Block Kingdom behind, Luffy and the others find themselves facing a vast snowy landscape and a massive suspension bridge. They resolve to move forward, only to be halted by approaching figures and a mysterious roar.

Luffy encounters Loki, the Accursed Prince, who offers him a deal. He hints at a connection to Shanks, all while savage beasts crowd around, staring Luffy down. Meanwhile, Zoro and the others on the suspension bridge realize someone is following them.

As the Great Erik, carrying Robin and the others, reaches the island of Elbaph, a breathtaking rainbow stretches out before them. Yet even greater astonishment awaits them in the direction the ship is traveling.

Robin and the others finally arrive at the port of the Western Village in Elbaph.

Robin formally introduces Luffy and the others to Saul. Then his assistant, Ange, shows them around the school, where Usopp is shocked by the education being provided there. Meanwhile, Robin is taken to the library by Saul, where she is met with an incredible sight.

Robin, Chopper, Bonney, and Lilith enjoy the Owl Library.

Amidst the roaring banquet with the Giants, Luffy hears the legend of the Sun God passed down in Elbaph and learns why Loki is being held captive. In the Underworld, two mysterious guests appear before Loki, expressing their desire to recruit him into their order of knights.

Luffy and some of his companions snuck out of the banquet to explore the deceased king's castle.

Leaving behind a brutal parting gift, Shamrock and Gunko of the Knights of God abandon Loki and move on to their next strategy. Meanwhile, Franky is shown old wall paintings, and Robin reads an important religious text passed down since ancient times in Elbaph.

While exploring the abandoned castle, Luffy and the others find a strange mark on the floor of the throne room and hear a mysterious voice out of nowhere. At the banquet, Oimo tells Usopp the tale of a legendary man linked to the Pirate King.

Gaban challenges Luffy to try to take the key from him. Luffy goes for it, only to be overpowered by Gaban's sheer force. Meanwhile, Shamrock and Gunko summon reinforcements and plot a detailed strategy to disorient the Giants.

While observing the Jewel Tree Adam along with Ripley, Franky learns of Elbaph's weak points. Meanwhile, in the Underworld, Luffy and Zoro find a heavily injured Loki. As they argue over whether to unchain him, an unexpected turn of events blindsides them.

A massive snake suddenly attacks the Walrus School. Saul and the other teachers stand their ground to protect the children, but just then, another mystery strikes, plunging the school into pure panic.
