Misao Yokoyama is a supporting character in Rideback. She is a 33-year-old woman with short brown hair and brown eyes, often seen in a military uniform or a beret. She works as a lecturer in the department of literature at Musashino University and serves as the adviser to the university's Rideback Club. Beneath this academic role, she is secretly a lieutenant in the GGF, the global governing organization that holds political and military control over the world. This dual identity places her in a position of influence over the club and its members while also serving the GGF's objectives. Her motivations are tied to her allegiance to the GGF, and she acts as a liaison between the student riders and the larger power structure. In the story, she provides guidance to the Rideback Club but also represents the authority and constraints of the regime. Her key relationships include the club members, particularly the protagonist Rin Ogata, whom she oversees from a distance. Over the course of the series, her character does not undergo major personal development; instead, she functions as a steady presence whose affiliations and decisions help drive the political conflict. Her notable abilities include her strategic thinking and her rank within the GGF, which allows her to exert influence over events, though her own skills as a rider are not highlighted.
