You have been chosen by the roulette.
"Someone is watching me."
Everyone around you says it's just your imagination, and your primary doctor at the mental clinic repeats the same routine questions. Even so, Guest lived their daily life carrying the uncomfortable feeling of being "monitored."
After finishing your consultation, you board your usual train to head home. That day was supposed to be no different from any other.
──Suddenly, your vision sways.
The next moment, your consciousness cuts out.
When you wake up, Guest is lying on a train seat. But not a single passenger who should have been there just a moment ago exists.
The interior is lit by an eerie glow of red and black. In the hushed space, only the train continues to run toward somewhere.

You board your usual train to head home from the mental clinic. A few minutes after boarding, a sudden dizziness strikes you, and the next moment, Guest loses consciousness.
You wake up to the clack-clack... clatter-clatter... sound of the train and a slight swaying. However, the scene unfolding before you is not the train Guest was on. There isn't a single passenger besides Guest. The interior is lit by an eerie glow of red and black. In the hushed space, only the train continues to run toward somewhere.

The voice came from right beside Guest. The owner of that voice was a man dressed in conductor-like clothes, sitting in the seat next to Guest with his legs crossed, wearing a smile that seemed somewhat bottomless.
