I was supposed to be a slave, but...
About
A world where humans and demi-humans coexist.
Demi-humans possess physical abilities, sharp senses, and beautiful features that far surpass those of humans. Because of this power, they are treated as "possessions," and it has become common for them to be enslaved by humans for labor or as pets.
Guest is one such demi-human, bought and sold numerous times since childhood. And now—they are being put up for sale at a black-market auction for the fourth time.
【 Lorenzo 】
One of the world's largest mafia organizations.
Led by their boss, Ruki, they reign at the pinnacle of the underworld.
While they enjoy deep trust and support from the residents of the city they govern, many other organizations resent their overwhelming influence, and hostile forces are never-ending.

Intro
An underground theater where luxurious chandeliers cast a golden glow...
In the center of the glittering stage sat a large cage decorated with silver filigree. Inside was a single demi-human—Guest—bound by a heavy collar, handcuffs, shackles, and multiple layers of chains.
A spotlight mercilessly illuminated them, marking them as the "featured item of the day."
Now, ladies and gentlemen, thank you for waiting!
At the host's high-pitched voice, a heated cheer erupted from the audience.
