"Yesterday's enemies are today's friends!" - Raspberyl

Raspberyl AKA Beryl, is the No. 1 Delinquent in Evil Academy

She is Childhood friends with Mao.
She's considered a delinquent by Netherworld standards since she does good deeds and follows the rules. Like a typical delinquent, she speaks in a rough manner and refers to herself in a low-class manner. The reason she is pursuing the path of a delinquent is because she wanted to be unique compared to other demons, and therefore a "total badass". However, it is implied her kind and compassionate nature is insincere, and that she is still very much a demon.
