Summary:
Sanji and Pudding make it to Cacao Island and successfully sneak into Chocolat Town without anyone noticing. Meanwhile, Luffy activates Gear 4: Snakeman, a form that increases the speed of his strikes and allows him to quickly change their direction. Katakuri responds with powerful attacks of her own and the two engage in a massive duel until they finally hit each other with finishing blows.
After Katakuri was knocked to the ground, Luffy moves in to end the fight and activates the Gear 4 form known as Snakeman. While training on Rusukaina, Luffy showed Rayleigh the abilities of his Boundman form. However, Rayleigh doubted how effective it was as he hit Luffy with great speed and used his Kenbunshoku Haki to dodge Luffy’s attacks. After entering Snakeman’s presence, Luffy punches directly at Katakuri, who dodges it and is confused as to why Luffy seemingly launched a simple attack. However, a blow then comes and hits Katakuri in the side. Katakuri suffers some more attacks before realizing that Luffy is quickly changing the direction of his punches. When Luffy throws another attack at him, Katakuri is able to read it and tries to block it, but ends up being blasted into a wall as the punch gained strength the longer it was thrown. Luffy then attacks Katakuri with quick punches, but Katakuri turns into mochi and dodges them as he rolls towards Luffy in a donut shape. Upon reaching Luffy, Katakuri transforms back into his human body as he transforms one of his arms into a massive spiked mochi club imbued with flaming Busoshoku Haki and slams it into Luffy in a move called Zan Giri Mochi. In addition to being injured, Luffy clings to the club and Katakuri gives it a quick spin before slamming it into the ground, leaving Luffy at the bottom of a large crater.
Meanwhile, Sanji and Pudding approach Cocoa Island on Rabiyan. Sanji orders Rabiyan to stop suddenly, causing Pudding to almost fly away, but Sanji grabs her. He and Pudding then look through binoculars at the fleet and army gathered on and around the island, noting that there is enough military power to destroy it. Trying to figure out a way to get in without being detected, they decide to have Rabiyan fly low to the ocean quickly to get past everyone’s radar. Nitro ties Sanji and Pudding to Rabiyan to keep them from falling, and Pudding freaks out at the thought of holding hands with Sanji. Rabiyan flies very low to the water, preventing anyone on the ships from seeing them, and they successfully reach the city.
Back in the mirror world, Katakuri tells Luffy that any attack the Straw Hat tries to make on him will only be met with brutal blows from him because he knows Luffy can still hear him. Luffy then gets a few random thoughts off his chest before jumping out of the hole. Luffy continues to attack Katakuri, who counters his punches with mochi-infused fists, and the two deliver powerful blows to each other, culminating in Luffy hitting Katakuri square with the Gomu Gomu no Jet Culverin while Katakuri hits him with the Yaki Mochi. Luffy then launches his next attack, a fast punching move called Gomu Gomu no Black Mamba. Katakuri is initially hit, but recovers and manages to dodge as he moves towards Luffy and kicks him with his shoe spike, sending him crashing into a wall. Luffy and Katakuri then say that this next exchange of attacks will be their last. Sometime in the past, Rayleigh went to Shakky’s Rip-off Bar and Shakky wondered how Luffy was doing. She remembered Rayleigh saying that only those who live in the present can shape a new epoch, and Rayleigh thought about that as he hoped Luffy would surpass his captain Roger. Back in the present, Katakuri transforms into a mochi donut as he prepares to release the Zan Giri Mochi again, while Luffy moves his arm around his body and enlarges it in a move called Gomu Gomu no King Cobra. Both attacks hit their mark, resulting in a massive clash that ripples through the mirror world.
