Shirasu Erika

She is the head of the Shirayuri Dormitory, a dormitory that places importance on social status, such as position, bloodline, and financial power. She has a gorgeous face with the features of a Western doll. However, inside, she is self-centered and self-righteous. She is selfish, arrogant, and tyrannical. She looks down on poor people usng her family richness as yardstick, and she tries to expel anyone she doesn't like from the school with her cronies, even teachers. Her father has been donating a large amount of money to the school, so the school has left her alone for the most part.
