"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? Luffy finds a glass bottle floating in the water with a map to Omatsuri Island and a notice saying he's been chosen among the 100,000,000 pirates of Grand Line to go there for adventure. Of course everyone smells something fishy except the only person that counts, Luffy.So they go. It would appear that there's nothing special about the island but suddenly a magical theme park, parade and chorus all appear before their eyes welcoming them. At the center of it all is the Baron Omatsuri. What secrets and dangers wait for them on the island?
