Background

He becomes Lin Feng’s sworn younger brother after their first duel. Before Whitebeard and the crew, the two seal their oath with blood and take the titles of Big Brother and Second Brother 16.

Personality

Ace is energetic, optimistic, competitive, and eager to measure himself against strong opponents. After losing to Lin Feng, he accepts the result without bitterness and immediately promises to win their next match 16.

His loyalty to his comrades is absolute. When he learns that Marshall D. Teach murdered Thatch and fled with the Dark-Dark Fruit, Ace insists on pursuing him despite Whitebeard’s direct order not to do so 18.

Beneath his carefree behavior, Ace searches for the meaning of his existence and is unsettled by Lin Feng’s warnings about fate 36 38.
