Marina Nanami/Marine Pearl (七海マリナ/マリンパール) is a Filipino-Japanese girl from Japan who loves the sea creatures and the ocean that she dreams of becoming a Marine Biologist and an ocean-themed Artist in the future. Her birthday is on January 18th, just like mine.  

Flori Valdez/Topaz Flower (フローリー・バルデス/トパーズ・フラワー) is a Mexican-American girl who is also one of Marina's childhood friends from California, USA. Her birthday is on March 22nd.  

Mary Cambridge/Princess Diamond (メアリー・ケンブリッジ/プリンセス・ダイアモンド) is a British-American girl who is one of Marina's childhood friends from Florida, USA. However, she and her family permanently moved to California as a young child because she wanted a more diverse educational system and community in The Golden State and to be closer to Flori Valdez. Her birthday is on February 15th.  

Pearlie, Topaza, & Diamonte（パーリー、トパザ、ディアモンテ）are an adorable group of tiny Gemstone Fairies who are Magical Girl Mascot friends of Marina, Mary, and Flori who are inspired by Pearl, Topaz, and Diamond gemstones.
