Cover Page: Germa 66's Ahh... An Emotionless Excursion, Vol. 15: "Katakuri and Oven arrive!!"

The Vinsmoke siblings fight Katakuri and Oven.

Inuarashi and Nekomamushi appoint Carrot as the next ruler of the Mokomo Dukedom as they intend on remaining in Wano to serve Momonosuke. As Sukiyaki reveals himself to his grandchildren, the Straw Hats discuss his revelation that Pluton is located in Wano; however, a spying Caribou overhears this and gets excited about revealing this as well as information about Poseidon to a certain person.

A few days later, the Straw Hats and Yamato bid farewell to everyone except Momonosuke and Kin'emon, and the Straw Hats prepare to part ways with the Heart and Kid Pirates. Law gives Kid a rubbing of Kaidou's Road Poneglyph, and Kid reveals news about Dracule Mihawk and Crocodile working under Buggy to form the Cross Guild, which has issued bounties on Marines. Meanwhile, Yamato calls out to Momonosuke and Kin'emon from the roof of the shogun castle to announce his intention of joining the Straw Hats and living like Oden.

Inside the Flower Capital's castle, Raizo and Shinobu are being nursed back to health by Miyagi and Tristan while Kin'emon is forced to admit Ryokugyu had a good point when referring to Kaidou's presence keeping enemies at bay. He apologizes to the patients for not being there, before Nekomamushi brushes it off and asks Kin'emon how Tsurujo was doing. Kin'emon explains that she is safe and sound with only a serious burn on her face despite Okobore Town having burned down. He blushes while acknowledging her beauty even after all those years, while Inuarashi, Kikunojo and Raizo express their feelings about Kin'emon's sentimentality. Meanwhile at the remains of Okobore Town, Tsurujo and Chocho talk about Kin'emon's return, and how Tsurujo plans to move back to the Flower Capital so she can continue to remain by her husband's side.

Carrot is then called to the castle and is announced to be the new ruler of Mokomo Dukedom, much to her shock. Inuarashi and Nekomamushi explain this decision by telling her that they chose to stay in Wano to serve Momonosuke and leave the next era in her and the others' hands due to her experience at sea. Carrot disapproves, saying there are so many people stronger than her, but the Inuarashi Musketeer Squad and Wanda back up the decision by saying it's their job to protect their country and that most importantly, she carries Pedro's will within her heart.

Later, Kouzuki Sukiyaki shows himself to his grandchildren and the Scabbards, assuming all of the samurai knew as well (which was true except for Kin'emon, who internally expresses surprise to his survival). Sukiyaki tells them he can teach them a few things, but will mostly stay secluded from the public, wanting to leave the future to them. In another room, Franky and the rest of the Straw Hats learn from Robin that Pluton is indeed in Wano, but she hasn't seen it yet. Robin asks Luffy if he desires to obtain it, and he refuses, citing he doesn't need it, but Robin is left questioning why Oden wanted to unleash it on the world. A youthful-looking woman then butts into the conversation, which is revealed to be Shinobu, having regained her youthful form following Ryokugyu's attack. She is accompanied by Tama, who has become her kunoichi apprentice. Tama asks Luffy if she can join his crew, and he accepts following she masters ninjutsu. Caribou, who was eavesdropping nearby, is shocked by the truth about Pluton, and must let a certain person know about it.

A few days later, the Flower Capital becomes busy again. At the castle, Momonosuke barges into a room to ask Zoro to teach him some sword techniques, only to find no one. He searches around the castle, and learns from Hiyori and Toko that they already left, having said goodbye to everyone except him and Kin'emon. At Udon's Tokage Port, Luffy, Law and Kid choose their next destinations via Log Pose, the former two separating themselves due to their alliance having come to an end. Both Luffy and Kid pick to go east, while Law decides to go northeast, reasoning that it is the shortest route to reach an island. Luffy and Kid pick straws to decide who gets to pick the middle log, and Luffy loses while rubbing into Kid's face he is now an Emperor even though he lost.

While on the subject of Emperors, Kid takes out a flyer and voices his strong dislike for Buggy and his new organization: Cross Guild. With former Warlords Crocodile and Dracule Mihawk as his subordinates, he has become a powerful enough figure to obtain the title of Emperor.  Zoro voices his disbelief that Mihawk would become subordinate to anyone, and Luffy just calls Buggy an idiot. Still, Kid reveals that he's using his company to assign bounties to members of the Marines, remarking how so much changed in the outside world while they were in Wano.

Law gives Kid a rubbing of Wano's Road Poneglyph, and the latter reveals his crew had managed to take one from Whole Cake Island some time ago. Killer states that in order to take part in the upcoming war over the One Piece, they need to find a "man with a burn mark." Luffy questions him about it, before Kid laughs as he tells Luffy they now have an advantage over him and his crew.

Back at the castle, Momonosuke and Kin'emon search for Yamato, who was on the roof the whole time. He announces his intent to join the Straw Hats and live like Kouzuki Oden did.
