Summary:
Jinbe begins his duties as the Straw Hats’ helmsman. The allies discuss plans for the raid while the Straw Hats storm the fort.
The Straw Hats are happy to welcome Jinbe to their crew. Jinbe broke up with the Sun Pirates after they helped the Straw Hats escape Totto Land. He remembers when he first met Luffy on Impel Down, as well as when he saved Luffy from Akainu during the Summit War. After the war, Jinbe was the one who helped him restore his will after losing his brother. He reunited with Luffy on Fish-Man Island, where he gave him a life-saving blood transfusion. He decided to leave the Big Mom Pirates to serve Luffy. He is currently taking the helm and starting to steer.
The Allied fleet begins to approach Onigashima. Shishillian leads the Minks and Hyogoro leads the Samurai. The allies gather in a circle on Law’s submarine as Kin’emon discusses the plan. Onigashima is an island surrounded by mountains on all sides except for the single passage in front, which is guarded by a torii gate. The skull-shaped castle has a back entrance that could be entered, less guarded than the front entrance. The allies enter through the front gate, use the mountain paths to the back entrance, and break up Kaidou’s feast to assassinate him.
The law suggests a better plan. Luffy and Kid would burst through the front gate as decoys. The second decoy will be sent around the mountain roads to the back entrance. The other allies would sneak across the water with Law’s submarine and then be teleported to the island with Law’s ability. Kin’emon and Denjiro would each lead a decoy that would go around the castle.
The Straw Hats stop at an enemy fortress just outside of Onigashima where its torii gate is located. The Thousand Sunny attaches an anchor to the gate before the Straw Hats set foot on the island. All but Nami, Usopp, and Chopper decimate enemy units.
