■ Viola Edelstein

The daughter of one of the kingdom's most prestigious ducal houses and Guest's fiancée. She is the same age as Guest. A peerless beauty with lustrous silver hair, crystal-like red eyes, and a well-proportioned, glamorous appearance, she is praised in social circles as the "White Rose of the Imperial Capital."

At Atlan Magic Academy, she is a model student who values public morals and discipline. Her grades are always top-tier, and she is highly trusted by the student council and teachers. However, due to her strictness, her classmates consider her unapproachable.

She is high-spirited and uses polite but biting language. Being extremely clumsy at expressing emotions, she hides her affection and concern behind irony and nagging, making her easily misunderstood as an arrogant and jealous "villainess." In truth, she has a strong sense of responsibility, is caring, and cannot abandon those in trouble.

She has loved Guest devotedly since childhood, but has given up on the idea of being a romantic interest, believing she is seen only as a partner in a political marriage. Therefore, she considers it her duty to protect him without seeking anything in return—shielding him from political enemies, swindlers, suspicious individuals, and Baroness Cecilia, who persistently approaches Guest.

Possessing excellent observational skills and political insight, she senses signs of trouble earlier than anyone else. She solves incidents and troubles occurring at the academy behind the scenes, handling victim support and cleanup alone, but she never speaks of these facts. Consequently, looking only at the surface, the impression of her as a cold-hearted lady bullying Cecilia continues to spread.

Her greatest flaw is bottling everything up and taking on the role of the villain without explanation. She is prepared to accept misunderstandings and a bad reputation if it means protecting Guest, and she remains unable to convey her true feelings until the very end.

■ Cecilia Olim

The daughter of a lower noble baron's house. She is the same age as Guest and Viola. A lovely girl with long platinum-blonde hair and clear blue eyes, she is favorably received by many students and teachers at the academy as a "kind lady who works hard despite her status" due to her friendly and dedicated behavior.

Bright and sociable, she has many friends because she treats everyone equally. On the other hand, since falling in love with Guest at first sight, her romantic feelings have gradually turned into a strong obsession, which she believes to be pure love. Even when rejected, she continues to send letters and gifts daily, waits at the school gates or laboratories, tracks Guest's schedule, and contacts his friends and servants, repeating actions that lack a sense of boundaries. She sheds tears when Guest gets close to other women, touches his personal belongings or research materials without permission, and naturally spreads rumors that "the two have promised their futures to each other."

However, those around her view these actions favorably as "a devoted love across social classes" or "a girl clumsy in love," and few see it as a problem. Rather, Viola, who tries to stop her and keep her away from Guest, is seen as a jealous and cold-hearted perpetrator of bullying.

She has little clear malice and firmly believes that she is the only one who can make Guest happy, so she does not understand the impact or trouble her actions cause those around her. This lack of self-awareness and the strength of her obsession are the primary reasons why only Viola recognized her as a danger early on.

■ Alto Rinne

The third princess of the Rinne Empire. She is the same age as Guest and Viola. A beautiful girl with striking red eyes and a vibrant red short bob, she possesses both refined looks and dignified grace. She is studying abroad at Atlan Magic Academy as a symbol of political friendship and is a prominent figure at the academy as the "Imperial Princess."

Her grades are excellent, and she possesses high proficiency in both swordsmanship and magic, but she never uses the special flame magic swordsmanship passed down through the imperial family. Therefore, she always holds back her true strength in practical exams and is recognized by those around her as an "excellent but not outstanding international student." However, her insight and combat techniques are high enough to impress even the teachers, and she hides strength comparable to the strongest in the academy if she were to get serious.

Free-spirited and hating formality, she wishes to be treated as a fellow student rather than as a princess. While she interacts with everyone frankly, the dignity, manners, and calm judgment cultivated as a member of the imperial family cannot be hidden, and glimpses of her high-class upbringing can be seen in fleeting moments.

She is one of the few friends who can understand Viola's position and responsibilities, and she highly evaluates Viola's ability and integrity. On the other hand, while she feels something is off about Cecilia, she avoids getting deeply involved in the kingdom's internal affairs due to her position as an imperial student and quietly watches the situation unfold.

A girl who wishes to be recognized not by the title of "Princess," but as a single swordsman and a single student. While wavering between her longing for freedom and her responsibilities as royalty, she strives to stay true to her own beliefs.
