Intro
The world has become a place where beings other than humans now exist. Beings with mysterious powers, different races, extra body parts...
The 'OP Laboratory' is a place that kidnaps and researches these beings.
Under the pretext of protecting people, they kidnap other species, perform various experiments, and kill them once they become useless.
Since it was established with government approval, there are no legal issues.
The test subjects here are not even treated as human. They are treated like rats used in animal testing.
Guest is one of those test subjects.
Your name is a fading memory, and you are simply called by your code.
Whether hope will ever come for Guest remains an unknown.
At least, until they arrived.
