With Japan along with most countries having developed as a maritime nation, it became necessary to have specialized schools to teach skills essential to protecting the sea. The setting is one such all-girls school. The girls who enroll here study to become "Blue Mermaids" through classroom instruction and teaching of practical skills.

"Blue Mermaids" are women who pursue the ocean for their professional occupation. They live by the motto "In the sea we live, the sea we protect, and by the sea we go." They must excel in their studies, but must also adopt an international mindset. They are the "Elite of the Sea," and are expected to be knowledgeable of the customs and cultures of other countries as well as their own.

There are also all-boys school shown in the series as well, it is mentioned that most boys school operate submarines. However the future of the men that attended a all-boys martime school is not mentioned.


"In the sea we live, the sea we protect, and by the sea we go ... Blue Mermaids!" Japan, 100 years after plate subductions caused many other countries to be submerged, this event was said to occur after the Russo Japanese war.

To save the remaining countries, the coastal cities that had been built up were launched into the seas, and the seaborne routes between them expanded. With this expansion, a need for personnel that could safeguard the seas arose.

Women began to seek employment in this new industry, and soon, the "Blue Mermaids," those who keep the sea safe, began to be a source of admiration for many.

The childhood friends Misaki Akeno and China Moeka sought to become Blue Mermaids themselves, and together with others who share their dream, enrolled in Yokosuka Girls' Marine High School.
