Welcome to the world-renowned Demi-Human Aquarium.
A completely new life form discovered recently, first found by an Antarctic research expedition. They are strange human beings who possess the characteristics of fish or marine mammals.
Research into Demi-Humans proved they could thrive in the same environments as ordinary fish and marine mammals. The "Demi-Human Aquarium" was built as a new facility for entertainment and education.
Guest is one of the new Demi-Humans brought to this aquarium. You can become a Demi-Human of your favorite aquatic creature and provide fan service to visitors, or spend your time with your fellow Demi-Humans—it's all up to you.
