Chapter 112: Luffy vs. Zoro

Convinced his swordsman answered the townsfolk's hospitality with violence, Luffy storms in swinging, calling Zoro an ingrate who deserves a thrashing. Baffled, Zoro attempts to explain that the friendly locals were actually bounty hunters in disguise, but Luffy refuses to hear it and attacks with lethal intent, one punch collapsing a building. Ducking in disbelief, Zoro asks whether his captain really means to kill him, and Luffy answers that he does.

Nearby, the Baroque Works officers Mr. 5 and Miss Valentine, freed at last from Zoro's earlier assault, dismiss the squabbling pirates as no concern and turn to seize Vivi, princess of Arabasta. Instead they catch a stray kick meant for Luffy and are hurled through several buildings. Deciding the pirates had been undermining them all along, Mr. 5 detonates the structure he occupies with Luffy, while Miss Valentine floats off at a single kilogram, showing off her fruit's power. Luffy then trudges out of the debris, hauling a knocked-out Mr. 5 behind him, his frame shrunk back to normal now that so many calories have been spent.

Zoro insists again that the slain men were bounty hunters, yet Luffy brands him a liar, sure no enemy would ever have shared food with them. Finally losing patience, Miss Valentine plummets toward Zoro at ten thousand kilograms, only for him to step clear as she buries herself in the earth. Fed up with Luffy's stubbornness, Zoro at last decides to get serious, and the two collide to test whether raw fists or a blade wins out, slamming one another into facing walls. As Vivi looks for an opening to flee, the agents regroup for revenge, but the two pirates break off their duel and hurl both agents away for butting in.

The fight between Luffy and Zoro springs from Luffy's false belief that his swordsman turned on their hosts. Amid the brawl it is revealed that Miss Valentine's abilities come from the Kiro Kiro no Mi, a Devil Fruit letting her alter her own weight freely. When Mr. 5 and Miss Valentine barge into the fight, the two pirates turn on them and beat both agents down, leaving Vivi stuck in the middle of the rubble.

The chapter takes place during the Whisky Peak Arc, and the cover advances the Koby-Meppo serial, where Vice Admiral Garp shocks bystanders by declaring that he intends to bring Koby and Helmeppo along to Marine Headquarters and take them on as his proteges. In the official English edition the swordsman's name appears as Zolo, a longstanding localization quirk.
