Introduction
While sailing through the Grand Line, Luffy discovers a glass bottle. Inside is a treasure map to Omatsuri Island, decorated with playful drawings of treasure chests, flowers, and more! Fully in adventure mode, Luffy leads his bewildered crew toward the island.
However, Omatsuri Island turns out to be surprisingly plain… until a dazzling theme park suddenly appears! From behind a formidable pirate chorus, a gigantic man with flowers blooming on his shoulders—Baron Omatsuri—makes his entrance. His eyes gleam as he addresses Luffy:
"I’ll give you a secret treasure… but only if you can overcome the trials of hell!"
Those words—secret treasure and trials of hell—instantly spark Luffy’s adventurous spirit! The trials begin, filled with festival fun like goldfish scooping, ring tossing, and shooting games. But the trial masters—Muchigorou, Kerojii, and DJ Gappa—along with the Baron’s eccentric subordinates, prove to be anything but easy.
One by one, members of the Straw Hat crew vanish under attack, and with each disappearance, the eerie glow of the flowers on the Baron’s shoulders intensifies… What is truly happening in these trials? What secret treasure awaits at the end? Where have the crew members gone?
Now, in what has literally become a hellish gauntlet, Luffy must face the trials alone!
