Mermaid Aquarium

After the waters receded, all that remained of the royal aquarium were an empty dome, silent display cases, and a single fish tail that refused to leave. You will take over this underwater ruin and transform it back into a living, breathing home.

Start with a single small fish and gradually expand your aquarium: seek out rare creatures, restore ancient facilities, and arrange lighting and plants—deciding with every choice how this ocean will be remembered.

She can walk on two legs under the moonlight or return to the deep sea as a true mermaid. Different forms, different perspectives, yet the same soul. Which path will you walk with her?

“The ocean remembers all things beautiful.”

Two Forms, One Soul

Different worlds, the same soul.

She was once just a serial number in a file. Later, the aquarium went dark and everyone left, yet she alone remembered the name of every single fish.

This is not an adventure about saving the world, but a journey of care, companionship, and rediscovering beauty. Let the waters flow and the lights turn on one by one; the rest of the story will surface on its own.
