Misato Akasaka is a race commentator affiliated with the Umamusume Racing Association, responsible for providing live narration of the Twinkle Series. She first appears in the main Uma Musume: Pretty Derby anime, where her full name is revealed in the eighth episode, and she continues to serve in the same role throughout the franchise, including in the spin-off series Uma Musume: Cinderella Gray. Her visual design features green hair parted down the middle, bright green eyes, small but thick eyebrows, and a black headset with a microphone. She wears a white button-up blazer with a green ribbon, paired with an orange pencil skirt. Her demeanor is professional and composed, suited to her job of calling races with clarity and enthusiasm. She is a recurring supporting character whose primary function is to guide the audience through the action during races, offering context and excitement. In Cinderella Gray, which follows the career of Oguri Cap, Akasaka fulfills the same commentator role, appearing at major race events to provide narration. No significant personal backstory, individual motivations, or character arcs are explored in the available material; her role is strictly that of a neutral observer and narrator. She maintains no specific close relationships with the competing horse girls, instead interacting with all racers equally as a professional commentator. Her notable ability is her skilled live commentary, which helps frame the dramatic stakes of each race for the viewer. Over the course of the franchise, her presence remains consistent and stable, without notable development or change.
