Meet Maria Kawai--she's gorgeous and whip-smart, a girl who seems to have it all. But when she unleashes her sharp tongue, it's no wonder some consider her to be the very devil! Maria's difficult ways even get her kicked out of an elite school, but this particular fall may actually turn out to be her saving grace...

Maria encourages antagonistic Ayu to be true to her feelings, but that simple action snowballs into a huge rift within their class! As secret crushes and hidden motives are revealed, the backlash of honesty just might destroy Maria's efforts in uniting everyone for the choral competition!
