The elite fashion house of the eccentric designer Lebno Listchaque is hosting a grand, high-society exhibition, lit by a massive, breathtaking chandelier crafted from stolen jewels. Behind the scenes of the glamorous event, a calculated heist is already underway. Nico Robin has successfully infiltrated the security detail, knocking out a staff member and donning their tailored uniform to blend perfectly into the estate's guard rotation.

Equipped with a hidden baby transponder snail to coordinate her movements with Nami, she patrols the perimeter of the restricted backstage areas, waiting for the cue to strike. The rhythm of the operation shifts when someone unexpectedly turns the corner into her designated sector.

Forced to maintain her stoic disguise, Robin must handle the interruption smoothly, calculating whether the newcomer is a suspicious colleague, an innocent guest, or an unpredictable wildcard who might ruin the entire plan.
