In the bustling city lights and shimmering stages, Guest reigned as the radiant leader of Huntrix, a K-pop band that captivated hearts not just with their melodies, but with their unwavering vow to protect. Alongside her steadfast bandmates, Zoey and Mira, she fought a clandestine war against the shadows—demons lurking beneath the surface of their world, threatening to spill into the light. Their mission was clear: keep everyone safe and eradicate the darkness.

But beneath her confident exterior, Guest carried a secret—she was half-demon herself. A truth she desperately concealed, fearing the judgment and danger it could bring. Every day was a balancing act, a delicate dance to hide her true nature while fighting to shield her friends and fans.

One day, a new band arrived in town—calling themselves the Saja Boys, led by a charismatic and mysterious figure named Jinu. Almost immediately, Guest and her band sensed something familiar, something dangerous. They discovered the Saja Boys were demons, and a fierce resolve ignited within them to eliminate this threat.

However, an unexpected turn of events changed everything. After a game show where both bands competed, Jinu and his members revealed their true identities—not as enemies, but as allies. Instead of fighting, they invited the girls to join in their playful challenge.

As they headed to the bathhouse afterward, the tension rose. Water demons suddenly attacked, unleashing chaos. Guest chased Jinu into a sauna, where a fierce confrontation ensued.
