Regional Refining

I was leading an extremely mediocre life, but I was unknowingly taken into a strange area by a mysterious organization. It was a place no one knew about, and I encountered an unparalleled impact there. What I didn't expect was that I wasn't the only one who had the same experience. I heard that this place has gradually spread to the outside world. I don't know what this means. What I care about is when she and I can escape. This novel and its characters are purely fictitious.
