Vivian Moore, the villainess of an Industrial Era fantasy tale, inherits her family's legacy of ruthless business dominance—and a destiny spiraling toward catastrophe. Enter Nadia: a cynical secret agent whose only comfort comes from visual novels, suddenly thrust into Vivian's cursed body. Rather than surrender to a scripted downfall, Nadia hijacks fate with lethal precision. Anyone seeking her elimination gets brutally erased. Anyone attempting to dominate her discovers the hard way it's fatal. The weapon that makes her truly dangerous? The System—an all-powerful tool that transforms a marked villainess into an unstoppable force.
