Marinette has a lot of pressure, not to mention her school and love life! Now she has less time and opportunities to tell Adrien her feelings... Marinette now has to redouble efforts to protect her secrets and Ladybug will have to become stronger to face an indomitable adversary: Shadow Moth, who can now fuse the Butterfly and Peacock Miraculous! Thankfully, Ladybug can count on Cat Noir and their new superhero allies!
