Ally

Standing bigger than a typical girl her age because of the gigantification performed on her in captivity, Ally has dark hair and wears a pale sleeveless dress. When Kin'emon handed out warm clothing, the coat she received was light in color, trimmed with dark fur along the hood and cuffs and fastened with dark buttons.

Ally is a shy, ordinary child, a timidity made plain when Kin'emon's detached head sent her fleeing in fright.

Lured from her parents with the promise that an illness would be cured, Ally was confined inside Punk Hazard's Biscuits Room together with the other young captives. Their rescue came only when the Straw Hats forced the room open. The children had been fed NHC10 in candy form, and the withdrawal turned her wild, so after Usopp gassed them to sleep the crew chained the group for everyone's safety. Ally tore loose and lashed out at Nami and Usopp, then followed Caesar back to his laboratory in pursuit of the drug.

Inside the lab, Mocha seized all the candy and fled, and Ally joined the frenzied chase through the corridors, overpowering Robin's attempt to hold them. The children cornered Mocha, who swallowed the entire supply rather than surrender it, enraging them until the arriving Marines and Chopper sedated the group. Ally woke and ran with the crew and the G-5 Marines toward the exit as the deadly gas Shinokuni crept in, escaping the collapsing facility thanks to Zoro and Luffy.

After Law purged the drug from the children's bodies, Ally fretted over Mocha's condition and was reassured she would recover. When the Marines tried to screen the departing Straw Hats from view and branded all pirates as scum, Ally and the others insisted on thanking the crew that had risked everything for them, even declaring they would become pirates themselves one day. Traveling onward with the G-5 Marines, the children learned from Tashigi that Vegapunk would soon help cure them.
