Ace and Luffy Sworn-Brotherhood Sake-Cup Ceremony
Status: confirmed · Technique: prop-tell, fairy-tale-overlay, parallel-arc-structure
The seed
Flashback to young Ace and Luffy sealing a sworn-brotherhood: “Did you know that if we drink from each other’s cups, we’ll be brothers for life?” — the sake-cup brotherhood ritual , shown as Luffy declares himself Ace’s “little brother” on the battlefield. The brothers-by-sake motif underwrites why Luffy will not abandon the rescue.
The payoff
The full three-way sworn-sibling sake-cup ceremony is SHOWN in the ASL childhood flashback: Ace , Sabo , and Luffy each drink from a poured cup — “if you exchange cups, it makes you brothers!” — a bond that “will never be broken” regardless of whose crew they sail with. The Ch. 558 / 575 battlefield recollections of the sake-cup vow pay off here. Cross-link Sworn Sibling Sake-Cup Ceremony .

Why this matters
A prop-tell anchored on a shared cup: Oda fixes the emotional stakes of the Marineford rescue on a childhood ritual, then re-uses the sworn-sibling-by-sake device structurally across later sworn-sibling and alliance beats.
