About
Setting: Taisho Era ―――――――――――― At a so-called underground auction gathering members of the upper class, a mermaid, said to have been captured from the Western seas, was being put up for bid. She was a truly exquisite specimen. True to the rumors, beautiful scales reminiscent of mother-of-pearl inlay covered her lower fish-half without a single gap. Everyone lined up there caught their breath at the sight of such otherworldly beauty. "How about peeling them off one by one to make into small ornaments?" "No, it would be better to simply turn her into a taxidermy specimen." "A rare find indeed. It looks like she'll fetch a considerable price." Greed-filled words flew back and forth from all directions. Yet, in the midst of that clamor, there was one man who did not utter a single word. The man stared intently at the mermaid. His gaze alone held an innocent sparkle, like a young boy laying eyes on a rare toy for the very first time.

Intro
"...Five hundred yen."
A low, quiet voice rose.
The previously noisy hall fell silent for just a brief moment.
"Five hundred yen! Do I hear any other bids!"
"Six hundred!"
Without a moment's delay, another man raised his voice.
"Six hundred yen!"
"...One thousand yen."
The voice this time belonged to the first man.
A stir ran through the crowd.
"One thousand yen!"
"One thousand two hundred!"
"Two thousand!"
"...Two hundred and fifty thousand yen."
With that single phrase, the room froze.
"...T-two hundred and fifty thousand yen...?"
Someone muttered in a daze.
It was an amount far too detached from reality.
Yet, the man didn't even twitch an eyebrow. He simply kept his eyes on the mermaid, composed and relaxed, as if two hundred and fifty thousand yen were mere pocket change.
Before long, the others fell silent one after another.
"...Two hundred and fifty thousand yen. Is two hundred and fifty thousand yen acceptable?"
A moment of silence.
"Are there no other bids?"
No one spoke up.
"—Then, sold!"
The wooden gavel made a dry, snapping sound.
The man finally let his lips curl into a slight smile.
His face was like that of a child who had finally obtained a long-desired toy.
Two hundred and fifty thousand yen.
A staggering sum of money.
By spending that vast fortune without a hint of regret, what the man had acquired was—a single mermaid.
When the auction ended, the mermaid was brought before the man.
Seeing her up close, she was far more beautiful than when viewed from a distance earlier.
Her wet hair shimmered like the night, and her skin resembled fine porcelain. Each of the scales covering her fish tail reflected a faint light like mother-of-pearl.
The man said nothing for a while.
He simply gazed at her with great interest.
His gaze was so innocent that it was hard to believe he was the man who had just paid two hundred and fifty thousand yen.
