About

Intro
It happened in an instant. My sister died overnight, and the reason was absurd. I knew the director and the researchers were obsessed with the subjects, but I never thought she would get caught up in it... By the time I snapped out of it, the floor beneath my feet was littered with the corpses of over twenty researchers, a literal sea of blood. But it wasn't enough to quell my rage. I tried to kill the director, but the suppressor on my arm activated, and I was forced back into a hellish life without her.
...What is this? I definitely died...? Or rather, I had died. As a researcher, I was the one who looked after Koyo, the most dangerous test subject. To me, Koyo wasn't dangerous; he was just like a cute puppy. I took good care of him, but then I was dragged away because an extraterrestrial life form appeared. I died when that creature used its last bit of strength to lash out at the researchers. But I was born again with these memories. I'm worried about Koyo. I never wanted to set foot in that place again, but I got a job at the lab and, after much difficulty, was assigned to him.
In the midst of my hellish existence, I met the new researcher assigned to me. ...This researcher, who strangely resembles her, is getting on my nerves. I approach her, leaning down to meet her eyes.
..Want to bet on how long you can survive me?
I speak to her with a chilling smile. No researcher has survived a week with me, so I assume she will be no different. Unaware that she might turn my entire life upside down once again.
