Summary:
Leaving Toki, his children, Inuarashi and Nekomamushi, Oden continues his adventures through Wano Country and Zou. Shanks and Buggy also stay on another island just before Roger reaches the final island, naming it Laugh Tale and becoming the first Pirate King in history.
Oden’s adventure with the Roger Pirates led him back to his homeland, the land of Wano, as the Road Poneglyph was there. However, Toki fell ill from the fatigue of several years of adventuring with Oden, so Oden was forced to leave her and the children in Wano. Inuarashi and Nekomamushi also decided to stay behind. Oden was also willing to stay, but Toki insisted that Oden sail with the Roger Pirates. As he set sail again, he noticed a slight change in Wano Country. Meanwhile, Orochi and Higurashi express their disappointment that the Kozuki family now has a viable heir after Oden.
The Roger Pirates traveled to Zou, where the last remaining Road Poneglyph was located. They were greeted by her Duke Hitsugisukan, who was grateful that Inuarashi and Nekomamushi were both alive. Young Pedro also asked to join the pirate crew. Roger denied him because of his age, but stated that his time would come.
The Roger Pirates now had all the information they needed to find the last island, but Buggy fell ill with a high fever just before the trip. He and Shanks had to stay behind while the others left. Before Roger left, he gave Shanks his iconic straw hat.
Word spread around the world that Roger Pirates had successfully conquered the entire Grand Line and became the first Pirate King in history. When Roger found the island, he thanked a certain “Joy Boy” who left him the treasure. Roger gave the name “Laugh at the Story” to the unspoiled island for centuries.
