The Stories of the Self-Proclaimed Straw Hat Grand Fleet Vol. 23: Leo Arc - "Boys! We're gonna rebuild every last building in town!"

Short Summary
While Charlotte Flampe has her subordinates try to attack Luffy, he continues to be overpowered by Katakuri, but keeps getting up and fighting back, trying to strengthen his Kenbunshoku Haki. On Whole Cake Island, Stussy mentions to Niwatori and Mont-d'Or that the Tamatebako was what caused the collapse of the Chateau, and out on the sea, Sanji's team completes the cake preparations right as Big Mom threatens the Thousand Sunny with a very large Prometheus.

Long Summary
As the fight between Luffy and Katakuri continues in the Mirror world, the residents of Wheat Island are amazed that the two have been fighting for such a long time. Back at the ruins of the Whole Cake Chateau on Whole Cake Island, Baron Tamago receives numerous reports of the two fighting and numerous mirrors breaking, with Morgans presuming the Straw Hat's chances of surviving are lower than ever. Stussy reveals that the explosion caused during the wedding was from the Tamatebako they took, stunning Tamago and everyone else present.

Inside the Mirror World, numerous snipers are trying to shoot Luffy but are unable to land a single shot. One mentions he is simply too fast, causing Charlotte Flambe, the 33rd daughter of Big Mom to stab him in the shoulder. She marvels at the awesome power he has, commenting that all of his younger siblings view him as their favorite and wish to be his favorite; however, she strives to out do them all and help him defeat Luffy. She mentions that Luffy is persistant and laughs at his efforts, calling him pathetic. A bruised and bleeding Katakuri sees Luffy get up once more and resumes his barrage of attacks. As he launches a flurry of punches, Katakuri notices that Luffy tried to preemptively dodge several. He gets even angrier, bowling Luffy backwards only for him to get back up. While Katakuri begins to taunt him, Luffy remembers back to his Haki training with Silvers Rayleigh and calms his mind. Both launch large Gear Third sized punches at the same time, confirming Katakuri's theory (and fears) that Luffy is managing to slightly see into the future as well. After beating Luffy down once more, Katakuri says he knows of Luffy and the Straw Hat Pirates plan to meet up at Cacao Island. He mentions all his younger siblings that are en-route and that they will intercept the Thousand Sunny, as well as Luffy himself if he manages to escape.

Aboard the Nostra Castello, Sanji, Pudding, Chiffon and all the WCI31 chefs marvel about how they have finally finished. Capone Bege agrees that there did not need to be anything else added, with the other Firetank Pirates mentioning they're feeling faint from just the aroma itself. As the chefs begin to faint, Sanji approaches both Pudding and Chiffon and thanks them for helping make the cake. Pudding switches back to her villianous persona, claiming that all the other Straw Hats might be dead by now and that Big Mom might not even like the cake despite their hard work; she immediately tears up and apologizes, telling Chiffon she has no idea why she just said it. Puzzled, Sanji nevertheless says Luffy and the others are believing in him and that the cake will satisfy Big Mom.

As the Thousand Sunny continues to escape from Big Mom, Prometheus grows to an enormous size; Jinbe notes in horror that not even ocean water would have an effect on it anymore. Chopper utilizes his Monster Point form to try and combat it, amazing Perospero by his new form. Nami notes that it would be futile; Chopper agrees but says that he must do something. Big Mom prepares to destroy the Thousand Sunny but then catches a whiff of the aroma from the wedding cake.
