The Straw Hat Pirates arrive at Gran Tesoro, a large entertainment city-ship ruled by Gild Tesoro, and enter a tunnel where they are showered with gold dust. They emerge into a giant concert venue where Tesoro and his colleague Carina are performing, but are attacked by a pirate crew. However, they easily defeat the enemy pirates and land on Gran Tesoro, where they are welcomed by a concierge named Baccarat. Baccarat offers to give them a VIP stay on Gran Tesoro due to their fame, and drives them to the city’s most prestigious hotel. The Straw Hats then go to a casino to win money, and their luck allows them to win every game they play.
