After their adventures in Arabasta, the crew come upon another deserted island and split up tasks amongst themselves.

The match is between the Straw Hat Pirates and the All-Star Villains. The atmosphere is tense, as it has all come down to a special playoff that will be decided by a tiebreaker shoot out. With Nami and Vivi cheering, a crowd of thousands and Coby as the unwilling (and unlucky) goalkeeper, the stage is set.
