Prologue: Rise of the Gloomflitter

Paris has fallen into darkness under Chrysalis' reign and for 10 years, the heroes has been fighting against her akumatized victims..
Lila Rossi, now Iris Verdi, has managed to trick Marinette and all her friends into befriending her but they don't know that she is the one under Chrysalis' mask.
After Timetagger's defeat, Chrysalis unveiled her most formidable plan.
In a final battle, Ladybug is captured, leaving Cat Noir to face Chrysalis alone. Though he defeats her, Marinette's life hangs by a thread, and Adrien, consumed by grief and guilt, vanishes. Years later, a new villain emerges-Gloomflitter, wielding the Butterfly Miraculous with a singular purpose: to reclaim the Ladybug and Cat Miraculouses, rewrite fate, and bring Marinette back-no matter the cost. As former allies become enemies, Paris' future teeters on the edge of hoρe and desρair.
