Background / History

Under Garp's arrangements, Ace and Luffy live with the Dadan Family near Mount Colubo. Although Dadan initially frames his sixteenth birthday as an occasion for him to move out, Ace states that living with her feels like home and that he does not intend to leave. 27 37

Ace first encounters Duen while fleeing alongside Luffy after dining and dashing. Duen pursues them through the town but loses them when a cargo wagon blocks the route. 20 21

When Duen later reaches Foosha Village, Ace and Luffy mistake him for a restaurant employee pursuing them over an unpaid bill. Ace initially suspects Duen's explanation that he chased them because he sensed their strength, but eventually accepts it. 27 28

• Freckled face 20
• Loose tank top 27
• Wears a hat 32

Personality

Ace is intensely protective of Luffy and treats defending his younger brother's dignity as an older brother's responsibility. He immediately objects when Duen mocks Luffy and repeatedly pushes himself in battle rather than disappoint Luffy's expectations. 32 33

He is competitive and resilient, refusing to regard a spar as finished simply because he has lost. Even after repeated defeats and injuries, he continues challenging Duen and remains interested in understanding Duen's Devil Fruit ability. 33 34

Despite his suspicion toward Duen at first, Ace is capable of accepting friendship quickly. He comes to regard Duen as a friend through their shared meals, training, and recognition of Duen's strength. 28 35 36

Abilities & Skills

Close-Quarters Combat

Ace is an agile close-range fighter who can use improvised weapons and rapid movement to pressure stronger opponents.

• Uses a water pipe as a weapon, combining direct strikes with evasions and kicks. 32
• Pins Duen's broadsword beneath his foot to create an opening for a knee strike. 33
• Is described as considerably stronger than Roronoa Zoro at the same stage. 33
• Remains physically inferior to Duen in strength and speed during their spars. 34

Determination and Mental Resistance

Ace can continue fighting through pain and disruption, especially when Luffy is watching.

• Refuses to back down after being slammed, struck, and defeated multiple times by Duen. 33
• Can break free from Duen's Phantom Mirror, though usually in less than a second. 34
• His resistance does not prevent Phantom Mirror from affecting him or contributing to Duen's victories. 34

Equipment / Items

• Water pipe — used as an improvised sparring weapon against Duen. 32
• Hat — handed to Luffy before Ace begins his spar with Duen. 32

Relationships

• Monkey D. Luffy — younger brother. Ace is fiercely protective of Luffy, trains and competes with him, and refuses to let Duen insult him without a response. 20 32 33
• Duen Mond — initially a suspicious pursuer, later a friendly rival and friend. Ace repeatedly spars with Duen, loses several matches, and seeks to understand his Devil Fruit power. 28 33 34 36
• Curly Dadan — member of Ace's chosen family. Ace considers Dadan's home his own and values the free, comfortable life she provides. 37
• Makino — Foosha Village's bar landlady. She protects Ace and Luffy when Duen claims they owe an impossible one-million-Beli bill. 28

Story Role / Major Arcs

First Encounter with Duen

Ace and Luffy flee from Duen through town after skipping out on a meal. Duen's pursuit fails, but it establishes the misunderstanding that later causes Ace and Luffy to fear he has come to collect a debt. 20 21 27

Foosha Village

At Partys Bar, Ace and Luffy nearly attack Duen over the supposed one-million-Beli bill before Makino exposes the claim as implausible. Ace remains wary of Duen's motives but becomes more receptive after hearing that Duen wanted to meet them because of their strength. 28

Sparring with Duen

Ace accepts Duen's challenge to spar and fights with a water pipe. His desire to protect Luffy's pride drives him to continue despite being overwhelmed by Duen's swordsmanship and Red Nightmare-assisted Phantom Mirror. 32 33 34

Friendship in Foosha Village

Ace, Luffy, and Duen spend time eating, training, and fishing together. Ace acknowledges Duen as stronger and, alongside Luffy, comes to consider him a friend. 35 36

Sixteenth Birthday

Dadan's family gathers at Partys Bar to celebrate Ace's overlooked sixteenth birthday. Ace tells Dadan that he does not want to leave because her home has become his home. 37
