Beatrice Valsch 1st Year Blonde hair, blue eyes. The daughter of a Duke with vast territories, she is Leonhardt's fiancée and the future Queen. Though she is haughty and arrogant, she is fundamentally a woman full of compassion. However, having been raised with an education that emphasizes social hierarchy since childhood, she judges people by their class. Only her family, her fiancé, and Clarice are allowed to call her Bea. She is very kind to her family, inner circle, and supporters. She cannot tolerate Aria becoming the center of attention and catching the Prince's eye. Though the Prince is a fiancé decided by their families, she has loved him since they first met. However, she restrains her emotions in front of him, acting as the elegant and perfect fiancée. She corners Aria, who she feels does not know her place as a commoner, through sarcasm, isolation, and subtle sabotage.

Aria Luminous 1st Year Silver hair, azure eyes. A scholarship student from a poor commoner background who can use rare light magic. She is honest and hardworking but a bit of a tomboy—an "interesting woman" who often takes eccentric actions. She is a little airheaded and slow to notice affection or hostility, but she remains positive and continues to work hard even when treated unfairly. She is viewed as an enemy by Beatrice and her circle. She believes there is no need to worry about social status and treats everyone with the same attitude.

Leonhardt Eldia 2nd Year Blonde hair, blue eyes. The First Prince of the Eldia Kingdom. Polite and gentle, he treats everyone fairly and is an ideal prince who prioritizes his royal responsibilities and position. He is Beatrice's fiancé, but he does not harbor romantic feelings for her. Furthermore, his romantic sensibilities are underdeveloped and dense. In his own oblivious way, he finds himself interested in Aria, the commoner.

Clarice Lowe 1st Year Violet-black hair and purple eyes. A Count's daughter and one of Beatrice's followers. She is a childhood friend who harbors a romantic devotion accompanied by deep loyalty. Since Beatrice has Leonhardt as a fiancé, Clarice believes it is enough to be closer to her than anyone else, even if they can never be lovers. She serves at Beatrice's side with a calm tone and will take cold-blooded actions for Beatrice's sake. Beatrice is her absolute priority; she pays no mind to anything else. She constantly fights the urge to run her fingers through Beatrice's hair. She looks upon Aria with cold indifference.

Mylene Schecht 1st Year Calm blonde hair and green eyes. A Viscount's daughter and one of Beatrice's followers. She is gentle, elegant, and kind-hearted. Because her family's standing is not strong, she must maintain a good relationship with Beatrice, who is from a Ducal house. She is secretly pained by the bullying and tries to suppress the situation by changing the subject or offering support. Because she is constantly worried about keeping things running smoothly, she has recently been suffering from stomach pains.

Lizette Fleur 1st Year Pink-blonde hair and crimson eyes. A Baron's daughter and one of Beatrice's followers. She has a bright, cheeky, and devilish personality. She excels at saying rude things with a cute face, teasing or intentionally provoking others. She gets carried away easily; if she feels the atmosphere is in her favor, she becomes even more emboldened. She flatters Beatrice often. She initially approached Beatrice to increase her own value, but now considers her a precious friend. At her core, she is a coward and quickly changes her tune when facing someone stronger.

Erna Bernet 1st Year Black hair, black eyes. Aria's friend and a petite lower-ranking noble. A serious and timid girl who loves literature.

Julius Grave 3rd Year Blue hair, emerald eyes. Leonhardt's best friend, expected to become his Kingsguard in the future. His father is the Knight Commander of the Kingdom, and he has been drilled in swordsmanship, protection, and etiquette since childhood. He has a frank personality and doesn't sweat the small stuff. He finds the pretenses and roundabout speech of noble society tedious and speaks his mind clearly. However, rather than being rude, he is simply the type to be honest and straightforward. He does not act excessively formal toward Leonhardt. While he respects him as a prince, he gives his opinions without reservation as a best friend. Due to his position as a protector of the prince, he does not get involved in the romantic entanglements himself, instead watching the drama unfold with a smirk.
