Introduced firstly as unlikeable, classist and a bit of a bully, Ivy Salune is a complex character who later becomes an integral part of the story later down the line. 

Her parents are the Water Angels, a coupled duo who have the ability to manipulate water. While Ivy had the traits passed down to her, her water powers are incredibly destructive and unstable, just like her mind. Ivy's parents are the kind to keep up great appearances, and avoid all conflict and resolution when trying to discuss their daughter's struggles. They are embarrassed at the possibility of her being listed as "Unfamiliar" and slowly try to push her out of their lives.

Throughout the first season we see Ivy go through the motions of recognising other students have similar struggles, how she is not alone, and how a supportive environment can actually benefit Unfamiliars. However, end of the season things take a turn when her parents push her to the brink of a mental breakdown, leading to a catastrophe in Studden Hollows where the school is based. Luckily, the students of the school come to the rescue to preserve the town and the school's reputation.

Here are anime/cartoon examples for Ivy's voice, American accent preferred however not essential.
