Nae Tennouji

As the devoted daughter of Yuugo Tennouji, this elementary school student frequently visits the CRT TV Workshop after her classes. Though she shares a close, sisterly bond with Mayuri, her gentle nature makes her easily intimidated by Rintarou and Itaru. While not an official member of the Robot Research Club, she plays a vital role in the Robotics;Notes era, utilizing her professional connections at JAXA to provide essential support to the group.
