One Piece: Open Upon the Great Sea! A Father's Huge, HUGE Dream!

Aboard Pirate Zap’s ship, two weary crewmates—Bonnie and Max—dream of running away, only to find they don’t have the money to start over. Their plans are overheard by three children being held captive, and the eldest, Amanda, proposes a bargain: her father, a professional treasure hunter, left behind the location of a legendary stash, and if Bonnie and Max help the kids escape without trouble, they can claim as much treasure as they like.

The group manages a narrow getaway and reaches a small island, where they cross paths with Luffy and the Straw Hat crew. Their pursuers aren’t far behind, and before long Luffy and Amanda are seized and hauled back to the Bayan Pirates’ leader, who is also hunting the same treasure. With a rescue to mount and a treasure to uncover, the Straw Hats clash with the Bayan Pirates as Amanda confronts her long-held resentment toward the adventures that kept her father away—and begins to understand what drove him.
