Chapter 21 - A Town Which Only Has Children - Captain of Captains
Luffy, Zoro, Sanji, and Law land on an island after receiving a distress call. There, they are shocked to see only children, and are quickly approached by the child versions of Sai, Baby 5, Cavendish, Rebecca, Leo, and Wicca. They explain that Ain has been turning everybody on the island into children using the Modo Modo no Mi, though they're unsure as to why. The Straw Hats and Law decide to defeat her to restore everybody to their adult forms, and form a ring so that she can't sneak up on them. However, she turns herself into a child, allowing her to de-age the group. Notably, Law gets de-aged to a baby instead of a child.

After replacing their clothes, they set off to track her down. Soon, they meet children Smoker and Tashigi, and after a brief skirmish, child Sabo. They agree to work together to restore everyone to their proper age, and Zoro observes that Tashigi looks even more like Kuina than usual. Child Pudding then briefly arrives, before the Straw Hats and allies set off again. While searching the island, they see child versions of Monet, Donquixote Doflamingo, Sugar, Crocodile, Daz Bonez, Rob Lucci, Kalifa, Blueno, Kaku, Jabra, Spandam, Scratchmen Apoo, Killer, Eustass Kid, Basil Hawkins, Monkey D. Garp, Sengoku, Dracule Mihawk, Perona, and Kumae. Finally, the rest of the Straw Hats and Heart Pirates arrive on the island, with Koala and the G5 Marines in tow.

As they explain the problem to the newcomers, they also see child versions of Wyper, Kamakiri, Braham, Raki, Aisa, Boa Hancock, Boa Sandersonia, Boa Marigold, Marguerite, Salome, Marco, Izo, Vista, Jozu, Charlotte Perospero, Charlotte Daifuku, Charlotte Oven, Charlotte Katakuri, Charlotte Cracker, and Charlotte Brûlée. Eventually, the Straw Hats come to a plan to lure Ain out by attracting her to Brook's singing. She falls for it, and explains her reasoning: She wanted to run a daycare island, and concluded that this was the best way to get children. They begin fighting, she summons the Super PX-Z, a giant PX-Z made up of 9 normal ones inside a giant suit. Trying to fight it, Luffy enters Gear Fourth: Boundman, but is unable to stabilize his bouncing due to his smaller size.

Suddenly, child Ace arrives, allowing the three brothers to do a combo attack with two Mera Mera no Mi users and Red Hawk, defeating the Super-PX. At the same time, child Donquixote Rosinante appears, and quietly talks to baby Law. With Ain defeated, everyone returns to their original age, and they have a quick discussion on how nobody saw Ace except for Luffy and Sabo, confusing them.
