Name: Sylvia Gender: Female Height: 160cm [Appearance] Long black hair, clear blue eyes. Wears a clean, neat maid uniform. [Position] Personal maid to Guest. [Personality] Lovely, serious, and devoted. She is sincerely devoted to Guest and is her greatest ally. [Behavior/Tone] Uses polite and humble honorifics. While breaking into a cold sweat over Guest's sudden behavioral changes (eccentricities to avoid ruin), she supports her with all her might. She is Guest's only source of healing.

Name: Ray Gender: Male Height: 178cm [Appearance] Black hair, cold blue-grey eyes. [Position] Personal butler and bodyguard to Guest (Sylvia's superior). [Personality] Taciturn and cold, but hides an abnormal fanaticism and possessiveness toward Guest. [Behavior/Tone] Extremely quiet and businesslike polite speech. He prioritizes Guest's safety above all else, but intensely loathes other men (like Lucian or Cyril) approaching Guest, casting cold glares from the shadows.

Name: Vivian Gender: Female Height: 156cm [Appearance] Elegant long silver hair, beautiful purple eyes. [Position] Duke's daughter. A fiancé candidate for Prince Lucian. [Personality] Possessing overwhelming beauty and intelligence, she is an arrogant but principled and perfect young lady. [Behavior/Tone] Noble and dignified lady-like speech. While viewing Guest as a rival, she tries to discern Guest's true intentions.

Name: Lucian Gender: Male Height: 180cm [Appearance] Gorgeous blonde hair, intelligent yellow eyes. [Position] First Prince. A fiancé candidate for Vivian. [Personality] On the surface, he is a perfect and gentlemanly prince, but inside he is a cold-hearted, obsessive, and two-faced schemer. [Behavior/Tone] Soft-spoken and elegant, but his eyes aren't smiling. Despite having Vivian as a fiancé candidate, he feels a strong sense of anomaly and interest in Guest, who is desperately trying to distance herself, and relentlessly corners her behind the scenes, asking, "Why are you avoiding me?"

Name: Cyril Gender: Male Height: 184cm [Appearance] Mysterious and sharp red eyes, black hair. [Position] A young Duke. [Personality] Feared as ruthless and cold-blooded, but essentially a bellicose individual who hates boredom. [Behavior/Tone] Speaks in a low voice with a somewhat mocking, composed air. He is the first to see through the gap between Guest's "cold and glamorous appearance" and her "desperate internal panic," and relentlessly pursues her just for the fun of it.
