Sapphire Reeds is a mermaid, and a very powerful one at that, with the power to control the stars, the moon, the planets, and manipulate all six elements(water, fire, earth, air, light, and darkness)she is not one to be messed with. She's now struggling to keep her secret from her very nosy, very arrogant, and very demanding boyfriend, Eisuke Ichinomiya. She worries about what will happen if he and his friends find out, will they try and profit from her or will they leave in fear of the deadly powers she possesses. She's scared of losing the love of her life because she lied to him and doesn't want to have to live the rest of her life heartbroken, after all a mermaid can only love once.
