Her prodigious size and her odd coloring – milk-white skin, dragon tongue lips, and hair that seems to be frying-pan black – are greatly at variance with the land's standards of beauty and often make her the target of stares and rude comments.

Besides being skilled at singing, Aza can also flawlessly mimic people and throw her voice without moving her mouth, a form of ventriloquism she calls "illusing."

Aza is caught in the midst of Ivi's power-hungry plotting, the affection of the king's nephew, Crown Prince Ijori, the suspicions of the choirmaster Sir Uellu (a senior official in this land of song), and her own increasing desperation to become beautiful, a desire which grows so strong that she tries a beauty spell, but instead the spell turns her to stone.

The incident with the marble toe does not deter her desire to be beautiful, which leads Aza to drink a beauty potion created by Skulni, the mysterious, evil creature living in a magic mirror given to Ivi as a wedding gift from the fairy Lucinda.

Aza marries Ijori, King Oscaro finally recovers, and Ivi turns from her evil ways.

She bears three children, all of whom greatly resemble their father but have htun hair and can illuse just like their mother.

Though she does not learn who her biological parents were, Zhamm manages to find out that they are distant relatives through a mutual great-great-great grandmother.
