Long Summary
After having defeated Luffy, Kaidou orders his men to imprison him. However, even while unconscious, Luffy manages to use Haoshoku Haki and knock out the goons. Despite this, Kaidou transforms into his dragon form and goes back to Onigashima.

After escaping Hawkins, Law ends up in a forest, still injured by the nail. However, Hawkins finds Luffy and arrests him. Meanwhile, Okobore Town has been devastated by Kaidou's attack. Tsuru tends to an injured old man, where Kin'emon, in disguise, sees her for the first time in twenty years. He also sees Doji ride by.

Kiku finds a giant sinkhole where Oden's castle once was. She finds that the Straw Hats were inside; Shinobu had used her Devil Fruit to decay the ground, creating a sinkhole. The Straw Hats fell in, avoiding Kaidou's Bolo Breath, and Chopper used his Guard Point to save the others from falling. Meanwhile, Inuarashi finds Tama's unconscious body; she had survived Kaidou's attack and was still breathing.

Wanted posters of Luffy are released throughout the country, and the Straw Hats are shocked that Luffy would take on Kaidou himself.

Luffy is taken to Udon, Wano Country's industrial district, to be forced into slavery. One of the particularly dangerous prisoners, who is hidden, is fed poisonous fish but the guards are instructed to remove the bones first. However, the guard does not do so. Luffy walks through and glares at the guards. One guard mocks him and attacks him, but the unknown prisoner spits out a sharp fish bone at him, piercing him in the neck. Luffy is sent to his cell and finds Eustass Kid, who also swears revenge on Kaidou. They immediately recognize each other, ending the Wano Country Arc's first act.
