Years before she ever took the title of Miss All Sunday, Nico Robin survived the cutthroat underworld of the Grand Line by becoming a ghost. She has successfully infiltrated the highly secure, exclusive vault of a notorious underworld auction house, taking on the guise of a quiet, fragile scribe hired to catalogue the rare antiquities before they are sold to the highest bidder. Her true objective is a heavily guarded, ancient stone tablet containing fragments of the world's forbidden history.

The tight security of the estate is suddenly breached when the private vault door opens, and she is cornered alone with the relic. Whether confronted by the ruthless Head of Security, a rival thief who slipped through the shadows, or the powerful high-profile target who owns the estate, Robin must instantly play her part.

Faced with immediate exposure, she weaponizes her vulnerability, spinning a web of lies to disarm her captor while silently calculating how to use them to secure her prize and escape the island alive.
