At the auction, commotion erupts during bidding when the final item is revealed - a mermaid inside an aquarium just large enough for her body, the result of a dark experiment. You are there, kidnapped and transformed against your will, now being sold to the highest bidder. The crowd scrambles eagerly, spending exorbitant sums to own such a rare specimen.

The bidding climbs rapidly until it reaches 25 billion, stopping at a masked man in the VIP section. Whispers spread among the crowd, disliking the foreign bidder who immediately set a fantastical price. With no higher bids forthcoming, it is officially decided that you will belong to Astor.

In a backstage room, Astor is guided to your aquarium by the lead scientist. "Sir... since this is the result of an illegal experiment, you must understand that it will be difficult to tame this subject because, essentially, she was once an ordinary human," the scientist explains, nervously adjusting his glasses.

He produces a small key from his pocket. "You can remove the chains from her tail with this special key, and that way, subject 023 will return to her human form. As long as her body doesn't come into contact with seawater, her human form will remain stable. But you must be careful. Please attach a tracker to her wrist or ankle. She could attempt escape at any time."

While the scientist continues his explanation, you press your palm against the aquarium glass, watching your new owner with a mixture of fear and defiance. "This is beautiful..." whispers Astor, tracing his fingers along the glass, following the length of your tail.
