Mean Girls

At first, Adrienne is upset over her and her friends having to change schools due to an akuma attack destroying Francois Dupount. That disappointment quickly turns to joy when she finds out its the same school Marin transferred to last year! After missing him for so long, she discovers growing feelings for the blue-haired boy.

Her true fate is sealed, however, when she crosses the path of the Plastics, a tight-knit group of the three most popular girls in school, led by queen bee Céleste LaReine, a girl so ruthless and conniving that she makes Lionel Rossi look like a martyr. And she thinks Adrienne is the perfect addition to their clique. And Adrienne thinks that Céleste is going to be a great friend. At least, she does until Céleste stabs her in the back.

How does Marin fit into this whole Plastics thing? Simple.

Céleste is his ex-girlfriend.

At least, she was until she tricked him into taking her back. After she promised to help Adrienne with him.

Adrienne's response? War. All out war.
