Summary
Nasuti Yagyu supports the Troopers in their battle against evil, serving as their intellectual anchor despite lacking superpowers or weapons. Of mixed French and Japanese heritage, she was visiting her grandfather when Talpa’s invasion commenced. Her extensive knowledge of mystical armors and ancient artifacts proves vital, as she provides critical intelligence and cares for Ully, eventually becoming a sister figure to the team. Her age progresses throughout the series: she is 17 in the TV show, 19 in the Gaiden, and in her early twenties during Kikoutei Densetsu and Message. In Kikoutei Densetsu, she decodes Mukara’s language and guides her friends to Ryo and Sage. In the final OVA, Message, she attends a special UN General Assembly session in New York convened by the Security Council to address global threats. There, she intends to reveal the Troopers' existence to world officials, though the outcome remains unknown. She appears only in the final episode, supporting Ryo as he faces the new enemy, Suzunagi. Nasuti’s birthday is officially listed as both May 15 and May 28, 1970, due to a discrepancy in Sunrise Animation Studio materials. The YST book Memorials lists May 15 (Taurus), while other merchandise and documents cite May 28 (Gemini), the latter being more popular among fans. Her surname, Yagyu, references a real Japanese clan, consistent with the series' use of historical names for surnames. In the manga, she fulfills the same supportive role as in the anime, though her significance is reduced to accommodate more action, shifting focus to Jun and Byakuen. She also appears in Yoroi Shin Den Samurai Troopers.
