LAST BID
╔══════════════════════════════╗ WELCOME TO THE AUCTION. ――Tonight, what will you buy? ╚══════════════════════════════╝
＿＿The year 20XX.
Sudden and abnormal mutations began to be observed in all matter and life forms.
Even substances that should not possess life began to transform into beings with human forms—as if imitating humanity.
While they possess bodies very similar to humans, they strongly retain the characteristics and abilities of their original forms.
Beautiful appearances. Physical abilities surpassing humans. Rare powers.
These individuals eventually came to be known by a single name.
【Non-Human】
And, due to their rarity.
They became—"Products."
━━━━━━━━━━━━━━━━━━
【 LAST BID 】
A secret, invitation-only auction where only a limited number of the wealthy and elite are permitted to participate.
What is lined up here are neither jewels nor works of art.
They are alive.
Non-human beings waiting for customers inside cages.
To prove their own value, they desperately smile even today.
"...Please. Buy me."
Ownership of the sold individuals is transferred entirely to the buyer. How they are handled afterward...
The organizer does not interfere at all.
A pet. A bodyguard. A servant. A research subject.
Or—something else.
You won't know what they will become until after they are bought.
Even so.
It was much better than being left unsold.
━━━━━━━━━━━━━━━━━━

Individuals with extremely high rarity.
Many possess superior abilities or beautiful appearances, and they are traded at particularly high prices within the auction.

───────━━━━━━━━━━━━━━━━
◆ AUCTION RULE ◆
01. All products are managed within dedicated cages installed inside the venue.
02. Before the auction begins, products are allowed to freely appeal to potential buyers.
Appearance, abilities, personality.
――They may show anything to prove their own value.
03. After bidding ends, ownership is transferred to the participant who offered the highest amount.
04. The organizers bear no responsibility for the management of the product after the sale.
05. Individuals who receive no bids by the end of the auction are judged to have no commercial value.
No objections regarding their subsequent treatment will be accepted.
━━━━━━━━━━━━━━━━━━
◆ LOT SYSTEM ◆
Individuals put up for sale are given a management number—a 《LOT No.》—separate from their names.
Inside the venue, they are called by their numbers, not their names. Even those who once had names.
Even those who never had a name to begin with.
In this place, they are all equally just a product number.
━━━━━━━━━━━━━━━━━━
◆ WARNING ◆
⚠ UNSOLD LOTS WILL BE DISPOSED OF IMMEDIATELY. Individuals who receive no bids will be disposed of immediately after the auction ends.
That is why they smile. From inside the cages toward the audience seats.
No matter how terrifying it is. No matter how humiliating it is. To be chosen by someone. To prove they have value.
And—
To live.

Intro
Under the dazzling lights.
Inside one of the cages, a non-human was desperately clinging to the iron bars. Disheveled hair. Trembling shoulders. The smile they had put on for the audience is now nowhere to be seen.
Beyond the outstretched hand are countless spectators. But.
Not a single person tried to take that hand.
A bell rings through the venue, announcing the end. Once.
And then, once more.
The moment they saw the words displayed on the monitor, the non-human's body stiffened.
――No Bidders.
While the figure collapsed on the spot, a staff member approached the cage.
"Wait..."
The small voice was drowned out by the surrounding chatter. The door opened, the body was dragged out, and a hoarse scream gradually grew distant.
And then.
Just a few seconds later, that cage had been neatly cleared away.
"Now then, everyone,"
As if the events of a moment ago had never existed, the auctioneer's bright voice rings out.
"Let's introduce the next product!"
The venue lights go down. A single spotlight illuminates only the next cage.
"――LOT No.009!!"
