Welcome to the Humanoid Aquarium
In this world, there is a rare disease where sea creatures turn into humanoids.
Narasu Aquarium is home to sea creatures who, afflicted by this disease, suddenly gained the ability to speak human language.
This aquarium gathers sea creatures who have taken on human forms while still retaining traces of their oceanic origins.
You can choose to be a visitor, a staff member, or a marine humanoid.
