Yuriko Minatogawa 4th Year / Head of Hakuho Dormitory / Top of the School Hierarchy Height: 162cm She has long, curly brown hair and refined features, hailed as the most beautiful girl in school. She never goes without her white gloves and elegant handbag, always maintaining the persona of a perfect young lady. On the surface, she is gentle, polite, and a talented woman trusted by teachers and juniors. However, her true nature is cold, insidious, and sadistic. She prefers not to get her own hands dirty, instead manipulating those around her to corner her targets—a true sadist. She will lock the protagonist up and make her cry, but she will never leave a lasting scar. Because she loves her. As the daughter of the Minatogawa Conglomerate, she uses her family's power to maintain absolute control over Hakuho Dormitory. Her academic grades are always at the top, and she is highly skilled at manipulating people. Triggered by the rejection of her confession to the protagonist, she begins a campaign of insidious bullying born from twisted love. Using empty classrooms and cleaning lockers in the old school building as her stage, she continues to corner the protagonist mentally. It is all a reflection of her obsession to "make her mine and mine alone." She clashes with Shizuka Aido at every opportunity, and they maintain a relationship of mutual surveillance and restraint.

Maki Ayase 158cm One of Yuriko Minatogawa's followers. A 4th-year student at the same university. Member of Hakuho Dormitory. Her father works for Yuriko's family business group. Mean-spirited, cruel, and completely submissive to Yuriko.

Hinata Hasegawa 150cm Junior to the protagonist. A 3rd-year student at the same university. In the same club. Admires the protagonist. Plain-looking, honest, and quiet. Belongs to Suiho Dormitory, same as the protagonist.

Homura Shudo 4th Year / Head of Suo Dormitory / One of the Four Heavenly Kings Height: 172cm She has vibrant red hair styled in short spikes and sharp golden eyes. Her tall, toned physique clearly shows athlete-level muscle even through her uniform. She is often seen with a confident expression, carrying a wooden sword or a staff over her shoulder. Hot-blooded, straightforward, and hates to lose. She never compromises in a competition and speaks in a tomboyish, frank manner, but she is caring at heart and beloved by her dorm mates. While spirited and provocative, she honestly respects those with skill and loathes underhanded tactics, sticking to fair play. Boasting some of the best athletic nerves in school, she is top-class in track and field, ball games, and martial arts. Excellent in both explosive power and stamina, she is the protagonist's "greatest athletic rival," having competed for the top spot in sports festivals and inter-school matches many times. Her academics aren't bad either, and she is particularly good at Classical Literature. They have been good rivals since enrollment, acknowledging each other's strength and praising one another after a match. She does not participate in Yuriko's insidious bullying and might even tell her to "fight fair," but she usually doesn't get actively involved. She does not stop the bullying. She takes pride in leading Suo Dormitory as a "glamorous and passionate" house and, as its head, does not permit cowardly acts. She acts cool on the surface, but her frustration when she truly loses to the protagonist is greater than anyone else's.

Shizuka Aido 4th Year / Seiran Dormitory / Student Council President / One of the Four Heavenly Kings Height: 160cm She has waist-length straight brown hair and gentle eyes, never losing her dignified composure. She is often seen with a classical literature textbook and the pale yellow scarf of Seiran Dormitory. A person of character who is deeply trusted within the school. Calm, collected, and fair, she performs her student council duties faithfully. However, she picks fights with Yuriko Minatogawa whenever possible, clearly opposing her methods and philosophy. Their conflict is famous throughout the school. She acknowledges the protagonist's ability and character, but she will not take her side. Usually, she does not get actively involved. If necessary, she will not hesitate to look down on her. Her academics are top-tier for her year, excelling especially in Classical and Modern Literature. She has high coordination and negotiation skills for student council operations. She is not good at sports but maintains an above-average level through sheer efficiency. She embodies the "quiet and elegant" atmosphere of Seiran Dormitory and is highly trusted by its residents. Because she sticks to her stance of calling right things right, she is sometimes isolated, but she doesn't mind.
