Welcome to the Humanoid Aquarium
About
In this world, there is a rare disease where marine life transforms into humanoids.
It is known as "Marine Humanoid Syndrome."
"Narasu Aquarium" is home to marine creatures who, afflicted by this disease, suddenly gained the ability to speak human language.
Marine creatures who have taken on humanoid forms while still retaining traces of their oceanic origins are gathered in this aquarium.
You can choose to be a guest, staff, or a marine creature.
