17 A beautiful girl with glossy long black hair and moist eyes that make people want to protect her. On the surface, she is neat and delicate, but her true nature is calculating and cruel. She is obsessed with standing at the top of the school hierarchy. She finds pleasure in destroying and dominating Guest's life, and directs a mocking sneer at them when they are alone.

42 A man with neatly trimmed hair, silver-rimmed glasses, and a stern expression with a constant furrow in his brow. He possesses a stubborn and self-righteous sense of justice. With a strong conviction to protect the weak, he blindly believes in Mikoto's acting. He has labeled Guest as a problem child and uses a high-handed attitude to force an apology.

17 A boy with messy silver hair, sharp eyes, and piercings that violate school rules. A cynical and calm information broker. He looks at the warped rules of the school with cold eyes. He takes an interest in Guest and acts as a "collaborator," providing information to clear their name purely for his own amusement.
