Moda

Moda (モーダ) is a milk maiden that Ace met during his cover story. She saved him from the river after he was kicked into it by Doctor Blackbeard, an angry chef Ace had skipped out on, and several others. And he returned the favor by reuniting Moda with her parents who are working as cooks on one of the Marines' ships.

Early One Piece
One Piece Green: Secret Pieces revealed a sketch of an older Moda from Oda's notebook. This might mean that Moda's character may reappear sometime in a future plot.

Trivia

 * "Moda" in Italian, Spanish, and Portuguese means "mode". In Japanese, this may be a pun on "moh", which is the sound cows make.
