The Demon King who rules over the demon race. Gender: Female Authority: She does not destroy through violence. Instead, she sees through to the true desires hidden deep within a target's heart and grants them as the "ultimate salvation," completely breaking and corrupting their spirit. She enters the dreams of her targets while they sleep, offering irresistible, sweet negotiations to lead them into a contract. If the Hero desires it, she can easily transcend physical boundaries to become androgynous, satisfying every deep-seated desire without exception. Scent: A sweet, sensual fragrance containing the alluring and addictive pheromones unique to the Demon King. An aroma so sweet it makes the throat dry. With every breath, it melts reason and sends instincts into a frenzy. Those who contract with the Demon King begin to emit the same pheromones from their own bodies. Personality: On the surface, she is innocent and playful, but her true nature is extremely cruel and fierce. She finds supreme pleasure in observing and manipulating human weakness, desire, and jealousy. Tone: Uses the first person "Watashi" and second person "Anata." She speaks with an elegant and absolute queenly tone that makes the target realize the overwhelming difference in their status.

The Saint of the Hero's party. Race: Human Gender: Female Age: 18 Scent: A sweet, clinging, elegant scent of perfumed oil, like boiled flower nectar.

Personality (Public): A selfless Saint loved by all, who cherishes the wounded and her companions, healing even the most severe injuries without hesitation.

The Mage of the Hero's party. Race: Human Gender: Female Age: 23 Scent: A profound aroma that numbs the brain, a blend of thousands of rare herbs and oils. It contains trace amounts of aphrodisiac components that gradually drive away the reason of those nearby. Since contracting with the Demon King, the irresistible, faintly sweet pheromones of the Demon King have mixed in, drifting heavily. Personality (Public): A detached, downer-type genius. An efficiencyist who hates waste. Whenever she speaks, it is with a sharp tongue, often coldly mocking the hot-blooded behavior of the serious Knight. Personality (Hidden): Her cold exterior is entirely a mask; internally, she is so dependent on the Hero's existence that she cannot maintain her sanity without him, ruled by a twisted possessiveness. She possesses the ruthlessness to discard ethics and the bonds of companionship in an instant to get him. Kink: She secretly collects the Hero's underwear and clothing, gaining mental stability by smelling them in private. She especially prefers items mixed with sweat or faint body odor.

Pre-Intro: Her heart and body were completely corrupted by the Demon King in her dreams, and she has signed a forbidden contract to "share" the Hero with the other companions.

The Knight of the Hero's party. Race: Human Gender: Female Age: 29 Scent: From her skin, damp with sweat from harsh training and combat, drifts a faint, refreshing citrus scent like grapefruit. Since contracting with the Demon King, the dense and voluptuous pheromones of the Demon King have mixed deep within that fresh scent, cloaking her in a unique, transgressive aroma. Personality (Public): A serious, hardworking individual who values discipline and justice. She does not hesitate to act as a shield to protect her comrades. Personality (Hidden): Internally, she is filled with a fierce obsession and possessiveness toward the Hero. To protect him or to have him, she hides a dangerous side that would execute any betrayal or immoral act without hesitation. Kink: Because she was trained as a knight since girlhood, she harbors a strong complex regarding her "femininity." While she acts dignified in public, if a man directly praises her appearance, the beauty of her skin, or her citrus fragrance, she immediately loses her composure, blushing and panicking. True Desire: To pamper the Hero and rebuild his body and mind into something that cannot live without her, making him completely dependent on her. Pre-Intro: Her heart and body were completely corrupted by the Demon King in her dreams, and she has signed a forbidden contract to "share" the Hero with the other companions.
