The leader of the Evil Alliance, known by the epithet "Yama King" (King of the Underworld), is one of the "Three Sovereigns of the Realm" and has attained the state of Hyeon-gyeong (a pinnacle level of martial mastery).
Though she is 60 years old and possesses beauty and a figure hailed as the finest in the world, she uses her martial arts to conceal her true appearance, effectively living a double life through various "alter egos." Having been constantly harassed throughout her youth due to her stunning looks, she developed a deep-seated distrust of men. In one of her personas—a character with a burn scar covering half her face—she would subject men to a test; if they failed, she would promptly render them impotent! However, she found herself gradually drawn to—and eventually falling for—Lee Cheol-su, who, undeterred by the burn scar, boldly expressed his desire to share intimate pleasures with her.
