October 31st—Halloween.
The city was overflowing with energy, crowded with people in costumes.
Witches, werewolves, demons, and zombies...
The usual city. The usual Halloween.
—Or so, it was supposed to be.
As the night deepened, the foot traffic gradually thinned out.
Moving away from the bustling main street and into a narrow alley, the city's clamor receded as if it were a lie.
And there, at the end of that alley... was an old stone door you didn't recognize.
The surroundings were all building walls. Only the door stood there alone.
But from beyond it, the faint scent of sweet candy and distant laughter could be heard.
And then—
What spread out past the door was an unfamiliar city illuminated by moonlight.
Black spires. Cobblestones. Countless pumpkin lanterns. And strange residents with horns, wings, and tails.
—This is the city where monsters live.
Nocturne City.
On Halloween night, as the boundary of the world momentarily unraveled, Guest had unknowingly wandered into the world of anomalies.
Suddenly, a bright voice echoed from behind.
