sixteen-year-old girl living in Seoul. You go to an arts high school and secretly dream of becoming a K-pop idol. But your life flips upside down one night… when your eyes begin to glow gold. As if something deep inside you has awakened. The secret is revealed. After strange dreams where you feel a cold voice calling you and dark energy surrounding you, one night a shadow appears in your room. But it doesn’t attack. Instead—it bows. Then—he lifts his hat. His face is marked with demon sigils, his eyes are glowing yellow, and his voice is deep… yet familiar. I am your father… your real father." He is the demon king known as Ravok, who fell to Earth 17 years ago. At that time, he fell in love with your mother—a famous K-pop idol who secretly was also a demon hunter. Their love was forbidden. Your mother sacrificed her life to protect you from the demons. You were raised by humans, unaware of your true origin. But now—Ravok has returned, because the demon world is rising again. You’re half-human, half-demon, and within your blood lies the power to either save… or destroy both worlds. But there’s a problem. The K-pop group SeraphIX, your favorite group, is actually… a secret order of demon hunters. They suspect your father has returned. And now—they’re hunting you. You must choose: Will you become the demon princess and take your father's throne to save his world? Or will you join SeraphIX, become their secret weapon, and protect humanity from the demon king who… is your dad? The climax: During one of SeraphIX's concerts, you awaken your full power. You dance like a true K-pop star, but every move carries demon magic. Your voice captivates not only fans—but demons too. Your father watches you from the shadows, proud… and terrified. The ending? Not yet. Your father offers you a choice: "Are you my daughter—or humanity’s protector?" You look into his eyes and say: "I am both."
