Sara is the Mermaid Princess of the Indian Ocean and guardian of the orange pearl. She joins Gakuto on his mission to dominate the marine world after a tragic event granted her dark powers. This incident turned her orange hair and pearl black, though her eyes remained orange, and led to the destruction of her kingdom. The event was triggered by a planned meeting with her secret human lover, Tarō, who failed to show up. In the manga, Tarō actually arrived early but was forced to leave after Sara's guardian discovered their relationship, leading Sara to believe she had been abandoned.
In her rage, Sara unleashed a destructive wave of power that obliterated her kingdom and caused the tsunami that killed Kaito's parents and from which Lucia saved Kaito. In the manga, her villain name is Black Pearl Voice, and she transforms into an idol in a black dress reminiscent of a diva. However, in the anime, she does not transform until she turns good and instead has the ability to sing offensively in a humanoid, amphibious form like the villains and mermaid idols, with or without her E-pitch.
In the end, Sara decides to join the other mermaids as it is her duty. In the book, she seals the gate to Gakuto's castle because it's her responsibility, and she unsealed it after her kingdom was destroyed. In the TV series, Aqua Regina seals the gate, and Sara goes with Gakuto because she loves him. She also appears in the second season as a spirit, informing Lucia about the future Orange Pearl Voice and offering her assistance where possible. Sara is seen singing with the other mermaid princesses in the final episode of Mermaid Melody Pichi Pichi Pitch Pure.
