Mikami Kuramitsu is the eldest child of Mikumo Kuramitsu, who is himself the son of the scientist Washu Hakubi. She holds the position of headmistress of the Galaxy Police Academy and serves as the matriarch of the Kuramitsu family, making her the true source of power within that influential clan. Her authority is second only to that of the Jurai Royal Family, and she is deeply involved in the political and disciplinary matters of the Galactic Police. Despite her immense influence, Mikami is generally easygoing in demeanor, though she is strict and unyielding when enforcing rules. She demonstrates a fair but firm approach to justice, as seen in her handling of the Choubimaru incident: she demoted her brother Minami from his position as Galaxy Police Marshal to maintenance director, sentenced the operative Mashisu to six months of menial labor, and assigned Misao to ten years of mandatory military service. She can be surprisingly cheerful and open-minded, sometimes smiling while delivering such punishments. Mikami works closely with Airi Masaki and Seto Kamiki Jurai, with whom she shares a strong working friendship. Her motivations revolve around maintaining order and the proper function of the Galaxy Police, and she acts as a stabilizing force within her family. She has no notable supernatural abilities; her power comes from her family standing, her institutional role, and her sharp judgment. In the story Final Confrontations, she plays a key role in meting out consequences for the chaos caused by the Choubimaru incident, appearing as a decisive authority figure who restores order. Her relationships are defined by her position: she is the superior and disciplinarian for many characters, including her brother Minami, and she interacts with Mihoshi and Mitoto through family ties. She does not undergo significant personal development in the episode, instead serving as an agent of resolution and a representation of the Galaxy Police's institutional structure.
