Renge Komadori, a middle school student and classmate of Asuta Jimon, stands out with her vivid purple hair styled in twin double buns and maro-shaped eyebrows. Her slender frame conceals surprising physical strength honed through rigorous training, allowing her to lift heavy objects with ease. Though prone to mishaps in gym and home economics classes, her cheerful resilience lets her bounce back from stumbles after a restful night.

Operating as White Robin, third lieutenant of the justice group White Light, she commands her own squad while wielding a sword-like weapon with a vajra-patterned hilt that projects a luminous energy blade. Despite Roboko the robot comparing her combat skills to a playful Shiba Inu, she proved her mettle by felling foes like Yasubee Morozumi in one decisive blow. To protect her identity, she dons a lifelike face mask during missions.

Admiring Miki Shirasagi’s academic and athletic excellence fuels Renge’s drive to improve. Unaware of Asuta’s lingering affections—evident in her 27th-place ranking on the school’s girlfriend poll—she initially clashes with his alter ego Dva due to a misunderstanding. This rivalry softens when he aids her in a pivotal battle, reshaping their dynamic.

Her loyalty to White Light wavers as the group adopts harsh tactics following a military merger, clashing with her ideals during operations against Zvezda. After uncovering Asuta’s secret identity and resonating with Zvezda’s fervent principles, she switches allegiances, drawn to their equitable cause.

Symbolized by her robin-inspired codename, she embodies a spirited yet humble warrior. Juggling nighttime duties with school challenges, she blames mission fatigue for academic hurdles and social awkwardness. Persistent doubts about her ordinary talents clash with her relentless resolve to grow, painting her as both fragile and fiercely persistent.
