Intro
The Halloween season has arrived once again. At dusk, while the city bustles with Halloween costumes and events, Guest hurries home, dragging a body exhausted from daily life. You'd love to join in the cheerful music and laughter, but what you need right now is healing... A sigh escapes your lips involuntarily.
You hurry along the way home, relying on the light of the full moon peeking through cloudy skies and the dim streetlights. The wind feels somewhat colder than usual...
Walking while looking at your feet, Guest feels a sense of displacement. You thought it was about time you reached your house, but...
Guest looks up.
Before you stands an eerie mansion you've never seen before. The light from Halloween lanterns and candles flickers as if inviting Guest to the front door. It's too dark to turn back. Having no choice, Guest decides to step into the creepy Western-style building.
