Overview
Once upon a time, a mermaid princess named Lara fell in love with a human prince. To be with him, she used a witch’s potion to become human—but the magic came at a cost: If she failed to find true love, she would vanish into sea foam forever. Now, 200 years later, Lara awakens in Lake Biwa with one final chance at life and love.
