Appearance

• Wears Shanks's Straw Hat, which he regards as a promise he must uphold. 37
• Can stretch his neck and limbs over considerable distances. 34

Personality

Luffy is impulsive, competitive, and almost entirely guided by immediate interests—especially food, training, and competition with Ace. He and Ace dine and dash without hesitation, race each other toward meals, and quickly become distracted by the prospect of meat or dumplings. 20 27 34

Despite his carelessness, Luffy is straightforward and loyal. He accepts Duen as a friend after eating his dumplings, recognizes Duen's strength, and refuses to trade away his Straw Hat because of his promise to Shanks. 36 37

He is easily provoked and produces intense negative emotions when Duen tricks or teases him, but he also moves on quickly when offered food or friendship. 28 33 35

Story Role / Major Arcs

Encounter with Duen

Luffy and Ace first appear while stealing food, fleeing through town as Duen chases them. They evade him by turning through alleys and using a cargo cart to block his path. 20 21

When Duen reaches Foosha Village, Luffy and Ace mistake him for someone seeking repayment for a restaurant bill. Duen exploits the misunderstanding to collect negative emotion points before revealing that he had chased them because he sensed their strength. 27 28

Friendship and Training

Duen finds Luffy and Ace on Mount Colubo and challenges Ace to spar. After Ace is defeated, Luffy reluctantly introduces himself, then unsuccessfully tries to pass a booger-covered hand to Duen. 32 33

Luffy witnesses Duen's Phantom Mirror and compares its visual effect to a kaleidoscope. He learns that Duen is a Devil Fruit user and identifies his own rubber power as coming from a Devil Fruit as well. 34

Duen's dumplings become central to their friendship. Luffy's appetite repeatedly overrides his anger at Duen's teasing, and he declares Duen a friend after being fed. 34 35 36

Straw Hat Dispute and Departure

At Ace's birthday gathering, Duen tries to convince Luffy that his own yellow-banded Straw Hat is superior. Luffy briefly considers the argument but firmly refuses to trade, declaring that his Straw Hat is his promise with Shanks. 37

Before Duen leaves Foosha Village, Luffy rejects a Pocket Den Den Mushi that Duen offers as a parting gift after Ace points out that accepting it would mean speaking with Duen regularly. 38
