BELLES OF THE BALL!Princess-slash-Arch-Saint Estorina has a wild favor to ask of the Wonder Trio-and to see it through, Marcela, Mile, and Mavis will have to attend a ball at the royal palace, soak up the limelight, and turn the whole party upside down! The chaos continues when a pretty young girl drops in from beyond the stars, followed by more hijinks with the elder dragons. There's never a dull moment for the invincible girls of the Crimson Vow!
