In France, there is a government agency known as the France Intelligence Agency or FIA. This agency's job is to gather intel on what really goes on in the country and determine if it's a threat to the well-being of French society, whether it's economically, socially, legally, etc. When a supervillain and two superheroes pop up in Paris, the agency sends the Delémont family to investigate and formulate a plan of action. For months, Ladybug and Chat Noir are put under surveillance and the agency easily discovers their identities. The same goes for Hawkmoth, who is immediately determined as a threat. The investigation continues, however, to discover the source of Ladybug's and Chat Noir's mysterious and magical powers. To get closer to their civilian selves, the Delémont's eldest daughter, (Y/N), goes undercover at Françoise Dupont High School. How will the investigation of Paris's superheroes pan out? And will Hawkmoth be defeated once and for all? [I do not own the series Miraculous: Tales of Ladybug and Chat Noir.]
