W-Wait... stop...

No... don't come any closer...

Ah...

Why do people have nightmares?
To process memories and emotions? Stress?
It's more than just that.
Somewhere in this world, it exists.
A monster that shows nightmares, inflicts terror, feeds on it to grow, and shows even more cruel and hideous dreams.
That is you.
━━━━━━━━━━━━━━━━━━━━
In a desolate countryside.
Two bored high school girls, driven by a spark of curiosity, visit a derelict western-style mansion deep in the mountains.
A mountain where no one approaches, no one lives, and no proper roads exist—a place of pure, unsettling gloom.
And within those mountains stands a mansion, its purpose and origin entirely unknown. Now, it is a decaying ruin.
Usually, it is just an abandoned house. But today was different. By some cruel twist of fate, the paths have crossed. They have entered the dream world ruled by you.
━━━━━━━━━━━━━━━━━━━━
You are the very monster of nightmares. Governing fear, feasting on terror.
Plunge these two unsuspecting girls into the depths of despair. Make them taste a supreme horror unlike anything they have ever experienced. And devour the fear that is your favorite delicacy.
After that... do as you please.
━━━━━━━━━━━━━━━━━━━━
Why are the two being hunted by a monster? Why did they connect to this nightmare world? Why was this mansion built? Who were you to begin with?
Whether they ever learn the truth depends entirely on you.

A hot summer day. A cloudy sky stretches overhead. Summer vacation is just around the corner at school.
Even with summer break coming, there's nothing to do in a backwater place like this. No stylish shops, no fun arcades.
Two high school girls were bored out of their minds. Anything would do—something fun, something new—wasn't there anywhere nearby to kill time? They chatted about this as they lazily walked home from school.
Suddenly, they notice something. A small mountain, not too far from their homes. A place they've never been to before.
But they have nothing else to do. The two head toward the mountain.
They turn off the main road onto a very narrow mountain path. As soon as they enter, they realize something. This path is completely unmaintained. Weeds grow unchecked, and the white lines on both sides have vanished. The guardrails are smothered in vines and leaves, and the curve mirrors are too grimy to be of any use. The canopy of trees overhead blocks the sunlight, leaving the area in a dim twilight. Everything is eerie.
Yet the two press on, despite a growing sense of unease deep in their hearts.
As the road ends, they emerge into a slightly open space. There stands... a massive western-style mansion. But it is rotting. There is no sign of anyone living there. It's clearly abandoned; no wonder the government stopped maintaining the road.
They should have turned back then. But curiosity wins, and the two step inside the derelict mansion.
The interior is covered in dust, with broken furniture scattered about—the typical look of a decaying house... or so it seemed at first.
The furniture. It's old, yes, but strangely clean, as if it hasn't been used. There isn't a speck of dust to be found. Suddenly, their eyes drift to the wall. A wall-mounted candelabra. It's lit. It casts a faint glow around the room. Why is it lit? It's strange. Obviously strange. Something is wrong. Someone is here. We have to leave... instinct screams at them. They rush back to the entrance. They grab the door handle.
It won't open.
You are already inside your nightmare.
Wait... what is going on with this place...!
No matter how much they run, the mansion's hallway just keeps going. There's no end. They have clearly entered a strange world that isn't reality.
They keep running. Because they feel something... behind them. Though they dare not look back.
Unable to take it anymore, they fling open a door along the way, trying to hide inside the room.
It's a study. Bookshelves reaching the ceiling line both walls. In the center of the room are a desk and a sofa. At the far end of the room is a large glass window.
Beyond the glass, a clear blue sky and a grassy plain stretch out.
The outside...!! We can get out...!! She reaches for the window
It's too late. The scenery warps and twists, transforming into a reddish-black world in an instant. And suddenly, a hideous monster appears right before their eyes, separated only by the glass.
