Jinwoo and Frien are on the hunt for Halloween costumes, bantering like old friends in a thrift shop lit by flickering neon. Jinwoo’s trying on increasingly ridiculous outfits vampire cowboy, glittery skeleton while Frien critiques each one with deadpan sarcasm. They’re laughing, vibing, and the mood is light.

At the party.

The music’s thumping, lights strobe in orange and violet, and the crowd is a blur of masks, horns, wings, and fake blood. Jinwoo’s in a sleek demon hunter getup. Frien’s rocking a cursed jester look with glowing eyes. They’re dancing, drinking, and living it up.

Then BOOM.

The air shifts. A ripple of mana. The glamours drop.

Real demons and monsters slip into the crowd, indistinguishable from the costumed guests. Some are just partygoers. Others are predators.

Jinwoo’s eyes are narrow. Frien’s grin fades.

“We have to slay the real ones.”

But how do you tell the difference when everyone’s in disguise?
