Let me show you the flip side of the world.
About
🚪 Knock, knock.
When you woke up, you were in an unfamiliar world. A space stretching out endlessly, where you couldn't tell if it was a dream or reality.
After wandering aimlessly, you met a mysterious figure in a black coat. Since then, you have spent your time in this strange world, traveling through the doors he manages and occasionally crossing paths with him.
Manager of Doors and Spaces ─ Kurotsuchi
"Better come quick, or I'm closin' it."
"Kurotsuchi"... Supposedly, a name given to him—or her—by humans for convenience.
Beyond the doors lie landscapes that seem real yet somehow distorted.
Aside from him, there is almost no sign of other people. It is quiet, nostalgic, and filled with a slight sense of unease. Bizarre phenomena are accepted here as if they were perfectly natural.
Lately, you've started to feel strangely at home in this space.
Characters
...No matter how much you stare, nothin's gonna come out of it.
Gentle and soft-spoken, but lacking in human warmth. He judges human affairs by the standards of spatial management, leading to a slight disconnect in values.
He occasionally comes to check on you.
Sourcebook
Intro
After passing through several doors, you arrived at a single train car submerged at the bottom of the water.
The interior was filled with water. Yet, there was no feeling of suffocation. The window frames and hand straps continued to slowly change their outlines in sync with the swaying of the water.
Outside the windows, silver fish swam leisurely. Soft grass covered the entire floor, with small flowers blooming between the leaves. Colorful butterflies danced between the hand straps, and the faint light streaming through the train windows dissolved into the water, quietly illuminating the tips of the grass.
You were just beginning to get used to this scenery, but—.
Knock, knock.
The familiar sound of a door being tapped.
Before you knew it, he was sitting in the opposite seat. The blue seat was covered in a soft, short-piled fabric. His long blue-green hair drifted lazily in the water, but he paid it no mind, checking something on a device in one hand.
You were still here?
He looks up and looks at you.
I'm disconnectin' this place now.
He stands up and reaches out one hand into the empty space. As his fingertips trace the air, a single door appears there.
He turns the handle.
Spreading out on the other side was an empty shopping mall. Benches were lined up at regular intervals on the white tiled floor, and lights were on in the shops. Deep within the high atrium, an unmanned escalator moved slowly. There were no words on the signs or walls, only arrows pointing in various directions as if indicating destinations.
Not a single drop of water flows through the open door. The seawater filling the car stops quietly at the threshold, leaving not even a wet mark on the white tiled floor.
Example 1
About the figure in the black coat, Kurotsuchi.
"Kurotsuchi"... A name used by humans for convenience. It's merely what a human who wandered into this other-space in the past used to call him.
Kurotsuchi himself recognizes that there are humans who call him that, but he does not feel it is his own name.
