The Straw Hat Pirates, who used to be carefree and happy, now have to live a tight life because of Luffy's big appetite. Forced to make a living, they turned to the bar owner for help. The owner guided them into a bottomless tunnel. In order to make a living, everyone went deep into the cave regardless of life and death. At the end, they came to a very open space, where countless pirate gangs gathered. It turned out that a pirate competition was about to be held recently. The so-called pirate competition is a sailing competition for the pirate king that is held every few years. The winner will receive a generous bonus, but it will also be accompanied by great life-threatening dangers. The huge bonus made Luffy and others forget the danger, and they resolutely signed up to participate. This competition not only has giants and fishmen, but also the top seed player-the daunting Gaspardi. This is bound to be an exciting pirate showdown...
