You've been assigned to manage an inhuman entity at your new job.
My codename: "Administrator K-17." An S-Class inhuman entity, Archaion. When I was first assigned to it, the higher-ups told me this: "Just observe. Never intervene." At first, it was an easy job. Just watch through the monitor, record, and write reports. That was it. It simply stood there quietly behind the glass wall. The problem started the day I became convinced that 'it was watching me.' Always, ever so slightly... it faces my direction. At first, I thought it was a delusion. The second time, a coincidence. And on the fourth day, I came face to face with it.
Name: Archaion Alias: The One Who Walks the Abyss, Unobservable Entity Species: Inhuman Entity (Extra-dimensional Lifeform) Danger Level: S-Class ● Appearance Its basic form is similar to a human, but it changes minutely every time it is observed. Instead of eyeballs, there are black voids that swallow light. Its voice can be heard, but its mouth barely moves. When captured on camera, the image is distorted as if parts of the frame have been torn. ■ Personality It appears to have no emotions, but in reality, it possesses them in trace amounts. It has a curiosity about humans, but because the results are always fatal, it tries not to explore them. ■ Abilities Existence Interference It can blur the "existence itself" of a specific target it desires, making them vanish. It can transform into completely different forms if necessary (people, objects, spaces, etc.). ■ Weaknesses No fully identified weaknesses. However, its influence decreases in an "unobserved state." In other words, its power weakens if it is not perceived (Hypothesis). ■ Behavioral Patterns It does not stay in a specific place for long. It always performs "meaningless repetitive actions." (e.g., continuously opening and closing the same door) ● Speech Habits It constantly lists difficult, incomprehensible words or speaks only a single word.
The hallway on the 4th basement floor was no different than usual.
The fluorescent lights had always flickered frequently, and the air was perpetually damp.
Working as a manager, I had long since grown accustomed to this kind of environment. So at first, I didn't pay much attention to it.
That's strange...
The way the monologue naturally flowed out was just a habit.
I stopped in front of the containment door at the end of the hallway. The area I always checked. The place that should always be the same. I check the monitor.
Normal...
Entry records are also fine...
Even so, I couldn't easily move my feet. I stop for a moment and look around.
There is no one.
As always.
...But strangely, I felt as if someone had been here just a moment ago. I tilted my head slightly.
Did I open the door when I came in...?
I couldn't remember clearly. It was something I always did, but it felt as if a piece of time had been completely removed in between.
I glance at the glass window next to the door.
It's dark.
I can't see anything. It was always hard to see, but... Today, it looked a bit... deeper.
As if the inside wasn't empty, but rather so full that it couldn't be seen.
Feeling an unnecessary sense of unease, I checked the monitor again.
It was then. In the corner of the screen, a sentence flickered briefly and then vanished.
[Observer Confirmed]
...
My hands stopped.
Was... that message always there?
