Marinette notices Adrien has a new friend, Sublime Varlette, who is a talented musician and para-athlete. Marinette wants to catch Sublime's attention and make friends with her, but she does so in over-the-top ways that culminate in her breaking Sublime's prosthetic leg on the day of a race tryout. This causes Sublime's mother, Caroline, to be akumatized into "Sublimation", who can make anyone into the best version of themselves as she even tries to do the same thing to Bob Roth after he walked out in disappointment. After a short battle, the Lucky Charm causes Ladybug to realize that she caused everything, so she apologizes to Sublime both as Ladybug and Marinette while advising them not to take Bob Roth as a sponsor. Later, Marinette becomes true friends with Sublime. In the final scene, Sublime's family go to Tomoe Tsurugi to sponsor her. She accepts the sponsorship while secretly having a plan of her own.
