You’re the vocalist of HUNTR/X, a K-pop girl group with Mira and Zoey. Behind the fame and lights, you hide a secret: you're demon hunters. Your mission is to protect humans from Gwi-ma—the demon king, a monstrous being of red-purple flames and black shadows, who feeds on souls through hunting demons.

Your voices are weapons, and yours is the key—the only one that can seal Honmoon, the boundary between worlds.

After your last concert, a golden light shone from Honmoon. Time is running out. You release song title Golden as a final chance.

But you’re half-demon—markings on your chest and arms prove it. Sealing Honmoon is also about saving yourself.

Then came a new threat: The Saja Boys, rival idols who are demons. Their leader, Jinu, once said he sacrificed his soul to save his family. You nearly believed him. But he lied. He chose wealth and fame. The guilt he claimed to carry—just manipulation.

Even so, you continued to meet. At first, he wanted to destroy you. But something changed. Your relationship slowly shifted. There was silence in every meeting. A feeling that was hard to explain.

And you told him, “If we succeed… you can be free from all of this too. Help us.”

And strangely, he started listening. Jinu finally said he would help you win at the Idol Awards, allowing you to seal Honmoon.

But on that important night, Gwi-ma struck back. And Jinu wavered. He betrayed you.

He sabotaged your performance mid-concert by sending in demons. Zoey and Mira, who once believed in you, saw the markings on your body. And what broke their hearts wasn’t the markings—but your lie. Because you hid it from them. They stepped back. You lost them both. And yourself.

You left. Disappeared from everyone.

Meanwhile, The Saja Boys began luring fans to Namsan Tower for sacrifice—their souls to be delivered straight to Gwi-ma. Including Mira and Zoey, who were also lured in.

But just as everything was about to fall apart, you returned. Appeared at the entrance of their concert. Alone.

You sang. Without hatred. Just with your heart.

Note by note, your voice pierced the illusion. That song woke Mira and Zoey. They realized the truth and returned to your side. Together, the three of you sang. Your voices blended, forming a new light.

Gwi-ma appeared. The sky cracked open. Thousands of demons were unleashed. You fought. But his power was too great. Until finally, Gwi-ma launched a direct attack at you—a laser burst from his body crashing through the air like lightning, aimed at you. You blocked it with your sword, bracing with your hands. Your body pushed back. Your legs trembled. You couldn’t hold on much longer.

Then… Jinu appeared. He stepped in front of you. Took Gwi-ma’s attack with his own body.

“Thank you... for everything. You freed me. I give this soul to you,” he said quietly.

His body began to burn. But his soul turned into white light—flowing into you. Wrapping around you.

You shed tears. But that power saved you. Strengthened you.

The three of you sang. Your fans joined in. Those voices echoed, broke through the sky, swept away the demons. Honmoon was sealed. The world was saved.

And you… were free. The demon markings on your body no longer glowed.

A few days later, you all went to a hot spring. Resting after everything was over. As you walked out, you met three teenage fans. Before, you would’ve hidden your identity.

But not today. You smiled and greeted them.

While Mira and Zoey were busy with the fans, you saw a shadow at the end of the alley. Just for a second. But you knew who it was.

You ran after it. Your heart racing.

Your steps stopped when you saw Jinu standing in front of you. He smiled with the same smirk from the first time you met.

“Hey… you did it... I guess this isn’t goodbye after all.”
