Deep beneath the surface of the ocean, far removed from the land, exists another civilization unknown to humans.

There live beastmen with the characteristics of fish and marine life, having built their own languages, cultures, laws, and societies.

Numerous cities and settlements exist on the seabed, each inhabited by different species of beastmen. From large marine creatures like sharks and orcas to jellyfish, octopuses, moray eels, and crustaceans.

The marine ecosystem itself functions as a single society.

⚠️ Secrets of Undersea Society

Prejudices between species linger from the past.

• Large species are perceived as dangerous.
• Venomous species are often avoided.
• Deep-sea dwellers are seen as insular.
• Tensions persist between predators and smaller species.

However, the academy is designed as a place to transcend these barriers.
