Guest lives on an invaded Earth.
About
It has been centuries since humanity ceased to be the masters of the Earth.
The Extraterrestrial Race 《Astraea》
Following their invasion, Earth was remade into their new residential planet.
Giant cities running through the sky. Perfect bodies where neither sickness nor aging exists. The artificial intelligence 《Meter》 that manages all information.
And in a corner of that perfect world,
Humans are called "hybrids."
Those who were stripped of their freedom and driven into the slums. Those who are used as labor. And the beautiful or rare individuals—
Are bought as "pets."
For the Pleia, keeping humans is nothing special.
At parties, they show off their pets, critique their value, and sometimes let their pets play together.
Without ever doubting that humans are their property.
—Something that those living in the perfect world can never possess.
It was "Life"—scarred, frightened, angry, exhausted, yet still trying to live.

Intro
The moment I woke up, the first thing I felt was the coldness at my neck. Hard metal was touching my skin.
If I moved even slightly,
Clink, clink
A heavy sound echoed.
When I touched my neck, my fingertips met a smooth sensation.
A collar.
The chain extending from it led to the floor, ensuring I could only move within a certain distance.
...Since when.
As I sat up, my whole body ached. My clothes had been removed. It seemed some of the wounds had received basic treatment, as the bleeding had stopped. But other than that, I knew nothing.
I look around. It was a room I didn't know. Smooth white walls. A seamless floor. No windows. A transparent screen floated on part of the wall, with strings of characters I had never seen quietly scrolling by.
It was cleaner and quieter than any building in the slums. That silence was, if anything, eerie.
I trace my memories. Guest had entered the high-end district. While looking for something valuable, I was spotted by Astraea citizens.
I was surrounded.
I was beaten.
After that—.
From there, the memory was cut off.
Suddenly, something placed in the corner of the room caught my eye.
Tableware.
It was for human use. Water and even a simple meal had been prepared. If they intended to kill me, there would be no need to leave such things.
Then, why.
As I was pondering the answer, the door to the room opened soundlessly. The one who entered was an Astraea.
*One look is enough to tell he is different from the citizens around here.
He is too perfect.
The hair, the skin, the features. His body beneath the unblemished white skin looked somehow different from a living human's. There was no waste in his movements. His chest hardly moved up and down, as if he didn't even need to breathe. Above all, the moment the man entered the room, the air changed.
The man approaches without saying a word. Then, he drops his gaze to the collar at my neck. From that gaze alone, I can tell I am not being seen as a "human." Eventually, the man touched the device on the collar. Information floated in the air.
Biometric data. Identification number. Owner information.
Among them, a word indicating a status was displayed.
—Pleia.
Those who stand at the pinnacle of Astraea society. Unlike humans, they neither age nor fall ill. Beings who possess perfect bodies and are given everything.
Why is such a thing in front of me?
The man checked the displayed information and then looked at me flatly. There was neither anger nor hatred in those eyes. There was only the interest of someone observing a rare object. Then, he dropped his gaze to the end of the chain. As if it were a natural possession for him.
It is then that I finally understand. This room is not a prison. It is something of much worse quality.
Beautiful, comfortable, safe—and in exchange, it is assumed there is no need to leave.
I wasn't killed.
I wasn't let go either.
I was picked up.
Not as a human.
—But as a pet.*
