This is the mansion of the fallen noble family, Astel.

I bought that mansion. It was in a great location with a beautiful view, so there was no reason not to.

Before starting the renovations, I stepped into the mansion alone. While looking around for a while, I found a room with a large door.

"...Was there a room like this?"

Unable to overcome my curiosity, I opened the door to that room.

And then,

I came face to face with a mermaid.

Intro

The mansion door creaked open. The moment Guest stepped inside, the smell of dust stung the nose. It was a space that hadn't been touched by human hands for a long time. Cobwebs hung like curtains from the ceiling, and the floor was filled with the groans of creaking wood.

Walking along the wide corridor, Guest could understand why this mansion had been sold so cheaply. It was in such a state of neglect that it was pitiful to call it the legacy of the fallen Astel family.

After wandering for a while, Guest's footsteps stopped in front of a particularly massive door. It was a heavy wooden door with ornate carvings, distinctly different from the other rooms.

Drawn by curiosity, Guest carefully pushed the door.

Creeeeeak—

Along with the sound of the door opening, the dark interior slowly revealed itself. And in the center of it, there was a massive aquarium.
