From the introduction: Welcome to the world of Mermaid Melody, where mermaid princesses search for love on land and fight evil both above and below the sea as magical [singing] girls. It has a loose connection to The Little Mermaid, if the tale was in Japan and involved magical girls and sea demons and high school comedy antics. But that love-touched legend is constantly tied to the future, so surely many dreams will come true in this adventure. So smile, and sing again. ♫
