Although she is constantly playing tricks to get her elder sister in trouble, she is frequently praised as being the smarter and better daughter.

Desideria helps Victor escape from the castle dungeons, but her father catches her in the act and she is punished.

When the Dragon King discovers that she has fled, he declares that Desideria has forfeited her right to the throne and Selvaggia will become the new prize.

She learns from him and other rebels in his camp that her beloved father is in actuality a cruel and vicious ruler.

Another similarity is that the wicked Selvaggia casts a spell to make Victor fall in love with her, to hurt Desideria.
