Description
Mia Koji, identified as Nasuti Yagyu in the original Japanese version, serves as a central supporting character throughout all iterations of the series. Of mixed Japanese and French descent, she is the granddaughter of Professor Konosuke Yagyu, a historian dedicated to researching mystical armors and artifacts. Working as his assistant at Sengoku University grants her deep expertise in the armors' lore and the threats emerging from the Nether Realm. Her grandfather's death amid the initial invasion propels her into the role of primary guardian for the legendary armors and their warriors.
Introduced at age 17 during the television series, she encounters the five warriors in Shinjuku during the invasion, swiftly becoming their indispensable strategist and protector. She delivers vital research, deciphers ancient texts, and utilizes her computer skills to locate the warriors when separated. Practical attire, frequently culottes or skirts, enables mobility during field investigations. Her ownership of a Mitsubishi Pajero jeep proves essential for group transportation across Japan, operated using her French driver's license obtained before Japan's legal age. She also provides refuge at her family's vacation home, offering the warriors emotional stability and a semblance of normalcy. Demonstrating resilience, she continues supporting them despite her grief following her grandfather's death.
Her role evolves across subsequent OVAs. In *Gaiden*, set when she is 19, her involvement is present but less prominent than in the television series. Within *Kikoutei Densetsu* (The Legend of the Inferno Armor), she deciphers the language of the antagonist Mukara and guides the group to Ryo and Sage's location. By the *Message* OVA, in her early 20s, she attends a Japanese government meeting with the intent to disclose the warriors' existence to world officials, though the outcome is unresolved. She appears only briefly in *Message*'s final episode, offering support during the confrontation with the new enemy Suzunagi.
Defined by intellectual resourcefulness and emotional fortitude, she occasionally becomes a hostage early in the series but adapts her strategies to avoid capture. Both she and Jun remain uncorrupted by the Nether Realm due to their absence of greed or malice, a quality enabling them to empower the Jewel of Life. Her dynamic with the warriors is distinctly familial, akin to an older sister, and she proves instrumental in all non-combat aspects of their missions.
