In a clandestine World Government lab, a forbidden experiment codenamed “Project Nika” unfolds—an attempt to clone the legendary Pirate King, Monkey D. Luffy, and weaponize his rubber powers. But when Nika-6, the sixth prototype, awakens with fragmented memories of Luffy’s life and a burning desire for freedom, the experiment spirals into chaos. Meanwhile, the real Luffy and his crew stumble upon a cursed island where nature itself morphs into rubber, its inhabitants mutating into grotesque hybrids. As ancient ruins whisper of an 800-year-old ritual tied to the “Drums of Liberation,” Luffy confronts a chilling truth: his powers are not just his own—they’re a key to awakening an apocalyptic force buried in the Void Century.
