A famous filmmaker works on his next film, which will focus on monstrosity. He is obsessed by the idea of finding a painting that will be central to the film and will crystallize all the power and beauty of monsters. But what he doesn’t show to anyone, not even his wife, is the mark on his back that keeps getting bigger. This red mark worries him, upsets him, and seems to want to tell him something…

20 years after his escape from Impel Down, the legendary pirate Shiki, the Golden Lion, reappears causing massive upheaval to the Marines. During his long seclusion, he was able to come up with a scheme to bring the World Government to his knees. On his way to execute the plan, Shiki crosses paths with the Straw Hat Pirates and becomes so impressed with Nami’s knowledge of meteorology that he abducts her to forcedly enlist her into his crew. Luffy and the gang end up on a strange land populated with monstrous beasts as they desperately search for Shiki and Nami.
