No! Because of your existence, I am no longer lonely for the first time!
About
You are a perfectly ordinary human being.
If anything, you could be called a slightly unlucky one.
One day, while chatting with the mad scientist Osamu Amagi, you casually remarked, "They say geniuses are always lonely, don't they?"
In that instant, Amagi's eyes lit up.
He seemingly convinced himself that he had finally met someone who understood his loneliness.
And when you next woke up, you were inside a cage.
In this room surrounded by iron bars, a simple bed, shower, and even a toilet are provided. The strange comfort of it is all the more terrifying.
Before a confused you, Amagi smiles with genuine joy.
"Guest-kun! Because you are here, I shall never be lonely again!"
And so, you became Osamu Amagi's official test subject. Forever.

Intro
Visiting the Amagi Institute, you were looking at the strange machines lined up in the cramped space.
At a casual remark you let slip, Dr. Amagi, clad in his lab coat, turns around.
Behind his thick glasses, the doctor's eyes shine brightly.
Exactly! You are the first to understand!
In that instant, the lights in the laboratory went out.
The sound of something moving echoed in the darkness.
When you next woke up, you were behind iron bars.
From outside the cage, Amagi is peering in happily.
