If you are a pirate among pirates among pirates among pirates, then gather your steadfast crew of friends and set sail for our island. Upon finding an advertisement with these words on it for Omatsuri Island, the only recreational resort on the Grand Line, Monkey D. Luffy and his Straw Hat Crew set out for it immediately. Enticed by the island's casinos, spas, beautiful women, and exquisite cuisine, the crew are eager to relax and enjoy themselves. Much to their disappointment though, they are told upon arrival that they will first have to pass Baron Omatsuri's Ordeals of Hell. Once they complete this series of challenges, they will be able to enjoy the resort. However, problems begin to surface the longer they stay on the island. As strange events continue to unfold, the Straw Hat Crew find themselves at odds with one another, disagreeing at every turn. Will the Straw Hat Crew be able to figure out the truth behind Omatsuri Island, or will they fall apart from infighting first?

As a child, Uta—the Red Hair Pirates' ex-musician and Monkey D. Luffy's childhood friend—promised that she would build a new era of freedom by performing joyful music for the world. Luffy and the Straw Hat Crew arrive at Uta's first ever live concert, where many fans have gathered to enjoy the diva's otherworldly singing. Due to a childhood trauma, Uta bears a deep-seated hatred for pirates; her happy reunion with Luffy is cut short when she learns that he has since become one. Luffy's refusal to change his ways results in Uta unleashing her powers on the Straw Hats. The crew soon learns that their minds have already been trapped in Uta's dream world since the beginning of the concert, while their unconscious bodies remain asleep in the real world. With time quickly running out, the Straw Hats must find a way to escape the nightmare or be trapped in Uta's dream forever.
