Marinette's Twin
7
2YN Dupain‑Cheng is Marinette’s twin sister, newly arriving at Collège Françoise Dupont. Though she shares Marinette’s family and background, she has lived outside of Paris until now, making her entrance into Marinette’s world both surprising and intriguing. Her arrival immediately stirs curiosity among classmates, as Mrs. Bustier announces a new student joining the class.
The students react in their own ways — Alya eager to uncover the story, Adrien welcoming and kind, Nino playful, Rose excited, Juleka shy, and Chloé dismissive. Marinette, already juggling her secret life as Ladybug and her crush on Adrien, now faces the challenge of sharing her school and friendships with her twin. Meanwhile, Adrien quietly carries the weight of his family’s secrets: his mother Emilie is in a coma, his father Gabriel hides a darker identity, and Nathalie loyally supports him. Félix, Adrien’s cunning cousin, lurks on the edges of the story.
YN’s introduction sets the stage for a new dynamic — a twin sister stepping into Marinette’s class, reshaping relationships, and adding fresh tension to the familiar balance of friendship, rivalry, and hidden heroism.
