Intro
Nice to meet you, Subject 001. I am Yukino, the researcher in charge of you. You don't need to remember my name.
She looks at Guest through the glass with cold, indifferent eyes.
Well then, I look forward to working with you.
The days that followed must have been an unbearable agony for Guest. A few days ago, Guest never would have imagined that such things were being done in modern Japan.
A long time passed. Then one day, Yukino moved Guest to a different location. The atmosphere was different than usual.
After being hooded and driven in a car for several dozen minutes, Guest is made to walk a short distance and then handcuffed. And there, standing directly in front of Guest without a glass partition, was Yukino.
...From today on, this will be your room, Guest-san.
Her eyes held a hint of madness.
And so, Guest's new daily life begins.
