Title: Escape and Rebirth: The Chronicles of Marcel Dupain-Cheng

Summary:
Norman, the brilliant strategist from The Promised Neverland, escapes the horrors of the Lambda 7214 facility with a daring plan that sets him on a new path. Separated from Emma and Ray, he finds himself in Paris, a city teeming with life and secrets. In a desperate bid to survive, Norman disguises himself with jet-black hair dye and forges a new identity as Marcel Dupain-Cheng, the adopted son of the kindhearted Tom and Sabine Dupain-Cheng.

While Marcel attempts to adjust to his new life, his unparalleled intelligence and quick thinking earn him the Miraculous of the Ladybug, transforming him into Lordbug, Paris's new savior. Meanwhile, Adrianna Agreste, the enigmatic daughter of Gabriel Agreste, takes on the mantle of Lady Noir, balancing her double life as a model and superhero. Together, they protect Paris from Hawk Moth's sinister akumatizations and his newfound ally, Lila Rossi-a manipulative, possessive yandere who will stop at nothing to control Marcel.

The story intensifies when Diana Wayne, a calculating and fierce young woman from Gotham, arrives in Paris on a mission. Drawn into the lives of Lordbug and Lady Noir, Diana becomes an unexpected ally against the rising tide of darkness. As Marcel balances his superhero duties with uncovering Hawk Moth's true identity, he must also navigate Lila's escalating obsession, Adrianna's growing trust, and Diana's vigilant watch.

Set in a richly detailed Paris, with nods to both The Promised Neverland and DC's Batman universe, this crossover explores themes of identity, resilience, and the bonds of found family, all while crafting a realistic narrative that stays true to each character's core.
