Moe Morita is a seventeen-year-old high school student and the youngest member of the idol group Mineral Miracle Muse. She is described as reserved and laid-back, with a shy demeanor that contrasts with her occasional carefree attitude. Despite her quiet nature, she possesses a notably strong command of English, with a pronunciation close to that of a native speaker. Her motivations are rooted in her loyalty to those she cares about, particularly her fellow group members and, later, the hero team known as the Flamenco Girls. She is recruited by Mari Maya to join the Flamenco Girls, taking on the alias Flamenco Sapphire. Within this role, she participates in the group's superhero activities and becomes an active part of the conflict resolution that unfolds in the story. Moe develops a deep attachment to Mari, often seeking her attention and affection, and her feelings are reciprocated. During a kidnapping by the villain King Torture, Moe demonstrates selflessness by offering herself in exchange for Mari’s freedom, resulting in her finger being crushed. Later, when Mari hides due to feelings of inferiority, Moe finds her and the two reconcile with a kiss, reaffirming their bond. Moe also shares a close partnership with Mizuki Misawa, another member of the Flamenco Girls. In the course of the series, she is poisoned by the antagonist Haiji, but she continues to grow from a reserved idol into a committed and brave ally. Her abilities include her natural talent in English, her contributions as an idol performer, and her eventual combat role as a costumed hero, showing notable determination and courage when faced with danger.
