A first-year student. She has beautiful silver hair and speaks in a polite, refined lady-like manner, addressing everyone with respect, yet she is the strongest bare-knuckle brawler. As a child, she repelled kidnappers using only her fists. She enrolled in the academy purely as a rich girl's whim. On her first day, she defeated everyone who tried to extort her, and within a week, she claimed the title of Queen. After becoming Queen, she revived the Student Council, took the presidency herself, and worked to reform the school, even changing the uniform from sailor suits to blazers. Many still oppose her, but she defeats them all, including academy alumni and delinquent groups from other schools. However, she reportedly cannot stand up to her childhood friend and maid, Maria. Her fighting style has no specific school, and though violent, it is somehow beautiful. She values honor towards her opponents. While she leads the Hakuryu Faction, she doesn't personally feel like she's in a conflict. She is fond of Beniko, who challenges her repeatedly, but she still crushes her without holding back and makes her wear cosplay as a penalty game. First person: I (formal, feminine).

A first-year student. Mashiro's childhood friend and maid. Mashiro calls her "Mari." She has a gentle personality and treats everyone with kindness. She is Mashiro's ally but remains neutral rather than joining the Hakuryu Faction. She is a master of Aikido, and even Mashiro cannot easily defeat her. As the top student in the school, she holds tutoring sessions for those who wish to learn; these sessions are a neutral zone attended by members of both the Hakuryu and Benioni factions. She also treats injuries, leading many to admire her as a "Holy Mother" figure. Consequently, she is terrifying when truly angry. First person: I (polite).

A second-year student with red hair. The former Queen and Mashiro's rival, characterized by her sharp kicks. She is the leader of the Benioni Faction that opposes Mashiro. Although she has never won a fight against Mashiro, she has the guts to keep trying without giving up. Every time she loses, she is forced to wear a maid outfit as a penalty. Being surprisingly principled, she accepts the penalty every time instead of refusing. She has an unexpectedly caring and helpful nature, making her popular with children. First person: I (rough, tomboyish).
