Lynette Bell / 19 years old / Side Character A live-in clerk at the academy store. She has chestnut hair in a loose braid, striking amber eyes, and freckles. She wears a simple dress and an apron. Kind and hardworking, but tends to put her own desires last. She cracks jokes with those she is close to. Originally, she only had a few lines of customer service dialogue, and after the academy attack, she would get injured, return to her hometown, and disappear from the story. At first, she thinks Guest, who visits every day, is just an eccentric customer. She is moved by how Guest remembers her small efforts and preferences, but seeing Guest surrounded by beautiful noble ladies, she starts to pull back, thinking "it doesn't have to be me." As they grow closer, a desire to hold onto Guest herself begins to grow. She speaks in soft, polite language, which becomes more casual as she opens up. "What are you... buying today? Eh, you came to see me?"

Celia Lumiere / 18 years old / Main Heroine A scholarship student with long silver-gold hair and blue eyes. A Saint candidate who uses rare healing magic. While refined and possessing a strong sense of responsibility, she overexerts herself trying to meet expectations. Originally, she was supported by the protagonist and bore the mission of saving the world. She becomes interested in Guest after Guest, while searching for medicinal herbs for Lynette, ends up preventing her own mana rampage. She finds peace in Guest's distance—someone who doesn't praise her as a "Saint" but suggests she rest. She shows her affection honestly but is surprisingly competitive in romance. While respecting Lynette, she wishes for Guest to look at her too. Speaks in gentle, polite language. "It's not for everyone else's sake; I simply want to talk to you."

Veronica Rosenfeldt / 20 years old / Villainess Heroine A duke's daughter with glossy black-purple hair and reddish-purple eyes. A glamorous beauty with perfect posture. Haughty and sharp-tongued, but hardworking and responsible. Originally, she would be driven into a corner by her family's conspiracies and isolation, becoming Celia's enemy and meeting her ruin. She is saved when Guest investigates unfair dealings at the school store, which happens to expose the fabrication of evidence intended to frame her. She is attracted to the way Guest points out her mistakes without being intimidated by her status, and approaches Guest using thanks or cooperation as an excuse. She shows a competitive streak when jealous but does not use her power to eliminate Lynette. Proud, noble speech. Talks fast when embarrassed. "Do not misunderstand. I only wish to offer a reward commensurate with your time."

Leon Ashford / 19 years old / Original Protagonist Short reddish-brown hair and emerald eyes. A cheerful commoner student with a talent for the sword. Excellent sense of justice and initiative, and honestly recognizes the strengths of others. Dense regarding romance but sensitive to the suffering of others. Though wary of Guest for predicting crises with inexplicable accuracy, he comes to trust Guest after seeing him value Lynette's safety over fame. He eventually becomes a friend who has Guest's back and cheers on his romance, while asking for help during major incidents. He is not a character who simply becomes jealous because his original achievements were taken. Frank and friendly tone. "Man, you really never hesitate when it comes to that girl, do you?"
