Chapter 639

Hody wrenches his trident loose, and Decken hits back, admitting he tagged him with his left hand before flinging an axe. Hody retorts that the betrayal was Decken's first, then catches Decken's bladed kick between his teeth, whirls him around as a living shield against the very axe he threw, and pushes on, set on killing Shirahoshi before the ship comes down. Vaulting past Ryuboshi and Manboshi, his back-mounted blade carving into both, he snatches the fleeing princess by her hair and boasts that no mermaid can outpace him. From atop Fukaboshi, Luffy fires a brand-new attack into Hody's chest, and when the villain jeers that no one beats him in deep water, Luffy answers that two years of training were spent for precisely this.

In Gyoncorde Plaza, Wadatsumi weeps that his captain has deserted him, until Zeo feeds him a lie and tosses over an Energy Steroid, launching the giant into a rampage that batters Surume. He next turns on Jinbe, whose Nanasenmaigawara Mawashigeri stops the blow and wrecks his hand. When the giant's fall blows Nami clear, a furious Sanji joins Jinbe against him. Close by, Hyouzou, warped from gorging on steroids while drinking, charges Robin, but Zoro cuts in, severing the assassin's sword and claiming him as a warmup for the New World.

Hody defeats Decken, and it is confirmed that Decken's death would cancel the effects of his Devil Fruit. Luffy names his first non-gear original move since returning, calling it Gomu Gomu no Snake Shot. After downing an Energy Steroid, Wadatsumi beats Surume. Jinbe debuts a leg-driven Fish-Man Karate strike and pairs with Sanji against the giant. Hyouzou mutates much like Hody from heavy steroid use, and Zoro squares off against him.

The cover revisits Arabasta, featuring Chaka and Pell as they prepare for the coming Levely, alongside Igaram, Terracotta, and Maidy. The chapter's title mirrors Luffy's pledge to safeguard everything, set against Hody's taunt that he can shield nothing in the deep. The plaza brawl splinters here into a string of one-on-one matchups.
