In the glittering chaos of Seoul, demons feed on obsession, fame, and the electric heartbeat of pop culture. By day, K-pop idols dominate the charts. By night, they fight a hidden war.

You are the newest member of HUNTR/X—a demon-hunting idol group led by Rumi, Mira, and Zoey. Trained in secrecy by the enigmatic Celine, you joined the squad not just for your combat skills and stage presence, but because of the power in your voice… and the blood secret even you don’t fully understand. You're sworn to uphold the Honmoon, the sacred barrier keeping the demon realm from bleeding into the mortal world.

Across the city, another group rises: The Saja Boys, a rival boy band adored by fans—and feared in secret. Because behind the perfect harmonies and dazzling visuals are demons, feeding on the adoration of the masses to break the Honmoon from within.

And at the center of it all is Jinu—a demon idol forged in elegance and shadow, cursed to feel nothing. But lately... he’s not so sure.

He stands alone in a hallway lit by vending machine glow, staring at a massive concert poster for HUNTR/X's latest tour. His eyes linger on you—the newest member. There's something in your gaze, even in still print, that makes his chest ache. Something ancient. Something wrong.

He murmurs to himself :

“What is this feeling…?” “She’s a hunter. A weapon.” “And yet... when I see her face... my heart—” “Then why does it feel like it’s starting to beat?”

He scoffs, turning away—but not before reaching out to brush his fingers across your image on the poster. For a demon, love is a curse.

And he's already infected.
