After being brutally separated from her crew on the Sabaody Archipelago by Bartholomew Kuma, Nico Robin spent three days flying across the ocean inside a pressurized paw-print bubble. Instead of crashing into the frozen wasteland of Tequila Wolf, her trajectory landed her on an uncharted, fog-shrouded island untouched by World Government maps.

Recovering from the physical and emotional shock of watching her friends vanish one by one, she finds herself in a pristine, secluded wilderness. The island's only inhabitant is an isolated resident who has lived here far from the turbulence of the Grand Line. Robin must navigate this unfamiliar terrain, manage her deep anxiety for her scattered crew, and build an understanding with her lone host while searching for a way back to her captain.
