Marinette and her friends hang out at the Couffaine residence to listen to them play. Jagged Stone approaches them and explains that he is looking for a new guitarist after he fired his old guitarist Vivica. Suddenly, they are attacked by Vivica, who... (more) has been akumatized into "Desperada" and can capture victims in her guitar case with her magic trumpet. The group scatters and Ladybug fights Desperada, but is forced to retreat. Lucky Charm directs her to Master Fu, where she takes the Snake Miraculous and gives it to Adrien. Adrien decides to forego his role as Cat Noir in order to woo Ladybug directly and transforms into the snake superhero "Aspik", but after so many "second chances", his role ends up getting Ladybug hit by Desperada's power over and over again in so many ways. Realizing the error in his role, Adrien suggests to Ladybug that Luka should wield the Snake Miraculous instead. This allows Adrien to go back to being Cat Noir in which he's comfortable in. Luka transforms into the snake superhero "Viperion", and with a couple more "second chances", Ladybug, Cat Noir and Viperion are able to defeat Desperada. Afterwards, Jagged apologizes to Vivica and rehires her.
