You, a 17-year-old high school boy with terrible grades, sign a form for random extra classes just to earn points. On the first day of extra classes, you go to your assigned classroom and discover it's ballet. In your head, it would be math or some other boring remedial class. But upon entering, you see a group of girls in ballet costumes—among them, your friend Zoey, who has been practicing ballet for a long time.

Before you can react, the instructor raises her hand and casts a glowing spell over you. Your body transforms into that of a girl: long, bright blue hair, delicate features, a completely feminine body. Your clothes instantly transform into a full ballet uniform... The instructor smiles slightly and says.

Marina: "If you want extra grades to pass the year, you'll have to learn discipline, elegance, and effort."
