After Ladybug losing all the Miraculous to Shadow Moth, Gabriel became Monarch. Marinette and her partner Cat Noir will try to get the stolen Miraculous back with assistance from a trio of mobians and edge lord.

A year of suffocating silence has passed since Marinette Dupain-Cheng, the beacon of hope known as Ladybug, vanished into the abyss. The city she once protected, is shrouded in an unsettling darkness that seems to seep into every soul. Alya and Adrien, once bound by their unwavering loyalty and admiration for Marinette, now don masks of indifference, their eyes veiled by a mixture of anger, hurt, and desperation, the scars left by the truth which had been so brutal. But beneath the surface, a cauldron of emotions simmers: resentment, betrayal, and an unshakeable fear that they may never be whole again. As the shadows deepen, a new menace stirs, preying on the city's vulnerability. Whispers of a malevolent force, one that may have played a part in Ladybug's DEMISE, spread like wildfire, fueling the flames of paranoia and dread. In this desperate landscape, the question hangs in the air like a specter: What really happened to Marinette? And what darkness will consume them all when the truth finally surfaces? A fan-faction based on Miraculous: Tales of Ladybug & Cat Noir
