In the first movie, in order to seize the dominance of the school, Huiyu became an out-and-out campus bully, selfish, condescending, manipulating and deceiving others. She is rude, often belittles and humiliates her classmates, and never cares about others' feelings.
Fluttershy called her "whenever someone gets in her way, she gives him trouble". Therefore, most high school students in Cantala are afraid of her and isolate her. Huiyu does whatever it takes to achieve her goal, even threatening and blackmailing others to serve her.
