I am Nanami Luchia, the mermaid princess of the North Pacific Ocean. I came in land to search for Kaito, a boy whom I rescued seven years before.
On the way, battling sea monsters with Hannon and Rina, mermaid princesses of the South and North Atlantic Oceans,respectively, using our voices and magical microphones, inherited to us by the past mermaid princesses.
Not only do we face dangerous missions or adventures, is it possible to find friendship and love as well?
