Miracle Queen

Hawk Moth, Mayura and Chloé know the identity of all Ladybug and Cat Noir's allies.

Wang Fu relinquishes his duty as guardian, losing his memory in the process, and Marinette becomes the new guardian of the Miraculouses.

This act also transforms the Miracle Box into a different shape, probably to avoid former guardians to see it and possibly recall it, similar for the reason why the Miraculouses' camouflaged mode looks different for each user.
