This episode was first shown in South Korea on 1 September 2015 as episode 1.
It is Adrien's birthday, but his father, Gabriel Agreste, a fashion designer, wouldn't allow him to have a birthday party. His best friend, Nino Lahiffe, gets mad at Gabriel's perceived unfairness; believing that adults want to stop kids from having fun, Nino is akumatized into the "Bubbler", and traps all adults in floating bubbles. After Bubbler is defeated, Adrien receives a scarf from Marinette, but his father's assistant, Nathalie Sancoeur, claims it is from his father.
