Summary

Dressrosa's people flee the Torikago, which shoves the wreckage of the town inward rather than slicing through it. Sai rallies the fallen Colosseum gladiators back to their feet. Climbing down from the King's Plateau, Viola realizes the cage's center is drifting toward Doflamingo, meaning even the island's heart will be shredded, and a frightened Usopp urges everyone onward. Kin'emon and Kanjuro chase Zoro for answers, and he stuns them by announcing his plan to stop the cage itself.

Key Events

On the Flower Field, Cavendish admires the reattachment of Law's arm and recounts how he foresaw that a victory over Doflamingo would make Luffy and Law the eye of a worldwide storm, which Law confirms is the goal. Atop the roof, Luffy kicks off his sandals, coats an arm in Armament Haki, and blows air into his muscles until his whole torso swells. Boundman is born, leaving him constantly rebounding. Doflamingo scoffs that the supposed trump card is merely bouncing, until Luffy sinks a fist into his body and unleashes a blow that hurls the Warlord into the Dressrosa streets.

Notes

Doflamingo's crash levels several buildings, and a Marine asks how he arrived there. The enraged Warlord finds himself pinned between his own cage and Luffy, who flies down, vanishes, and dropkicks him from behind. Luffy presses with Culverin, then lands a redirected punch to Doflamingo's face despite an evasion, while the Athlete kick fails to pierce his rubber body. Luffy explains the form was honed on Rusukaina to subdue the island's beasts. The color spread shows the Straw Hats picnicking with zombies, Franky's dance echoing Michael Jackson's "Thriller."
