Named for Momonosuke as the Kouzuki heir, this chapter pushes the young lord to plead his own cause before an alliance against Kaidou is sealed, while Jack steers back to the island bent on slaying the elephant that carries it.
Now that Oden's service under Roger is known, the crew understands that Kaidou and the shogun pursue Momonosuke and his guardians on the belief that Oden passed Laugh Tale's secret to the next generation. The truth is the opposite, since Oden refused to lay that weight on his heir. The three retainers announce their aim of retaking Wano and throwing its borders open, meaning to topple both the shogun and Kaidou with the minks fighting at their side.
Acknowledging the might of Luffy and Law, the swordsmen ask the crew to enlist, but Luffy refuses outright, stunning the room. He rounds on Momonosuke instead, demanding the heir speak for himself and scolding him for weeping. Recalling that Kaidou took both his father and his mother, the boy hardens and asks for help. Luffy agrees, binding the minks and samurai into a single alliance, though he insists on recovering Sanji first and decides to sail for Whole Cake Island with Pekoms.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

As the minks ready a feast to mark the rulers' reconciliation, Wanda, Pedro, and Carrot look back fondly on the days the pair were close. The calm shatters when Jack's fleet returns offshore. Annoyed that his subordinates failed, Jack waves off a plan to ambush the surviving minks and locks onto a darker target: killing Zunesha, the elephant bearing the whole nation. The chapter also records that a will of Oden's called for opening the country, and that Momonosuke knew nothing of the secret Kaidou and Doflamingo chased.
Chapter 819, Momonosuke, Heir to the Kozuki Clan, has the samurai retainers announce their plan to retake Wano and open its borders, allied with the minks. Luffy refuses to let his crew simply enlist and instead pushes Momonosuke to speak for himself, then agrees to help once the boy asks. Luffy also decides to sail for Whole Cake Island with Pekoms to rescue Sanji first.
In Chapter 819, Kaidou and the shogun pursue Momonosuke because they assume Oden passed on Laugh Tale's secret to his heir before he died. The chapter reveals this is false, since Oden deliberately refused to burden his son with that knowledge.
Luffy refuses to let the samurai speak for Momonosuke and demands the boy state his own wishes, scolding him for crying instead of asking for help. Once Momonosuke recalls that Kaidou took both his parents and asks for aid himself, Luffy agrees to form the alliance.
Jack sails his fleet back to Zou and, angry that his subordinates failed, abandons a plan to ambush the surviving minks. Instead he sets his sights on killing Zunesha, the giant elephant that carries the entire island of Zou.
