OVA
Description
Kaguya Shijuuin, a wealthy student of Musashino Girls High School, possesses thigh-length silvery-gray hair typically curled in four sections and bright violet eyes. She often wears a butterfly clip on her hair's left side, though her racing attire in the anime omits this accessory. Her standard school uniform features a lavender jacket with four buttons and a long purple skirt designed with a shorter front for ease of movement, paired with burgundy high-heeled shoes. For jet racing, she wears a full-body black and dark purple wetsuit adorned with small red triangles on the neck and shoes, maintaining short-heeled footwear for practicality.

Her personality initially appears stereotypically aristocratic, expecting deference like harbor clearance for practice. Yet she shows adaptability, proposing jet races to resolve disputes when challenged. Despite an outwardly arrogant demeanor, she exhibits deep loyalty and concern, especially for her teammate and maid, Kuromaru Manpuku. This is clearest when she forfeits a critical Kandagawa Cup race to prevent Manpuku's physical collapse. Her commitment extends to actively mentoring rival teams like Grindcore, using defeats to teach sportsmanship and the spirit of jet racing.

Her background involves generational service from Manpuku’s family, with Manpuku serving as both racing partner and dedicated maid. Kaguya knows of Manpuku’s shinobi heritage and frequently expresses appreciation, such as treating her to meals. In the video game narrative, her motivation for entering the Kandagawa Cup stems from her father’s threat to disband the school’s racing team. This storyline traces her growth from a win-at-all-costs mentality to recognizing teamwork and compassion. After deliberately missing a Cup deadline to protect Manpuku, she is surprised when other teams postpone the race in solidarity, allowing Dress to secure victory and preserve the team’s future.

Across different game story arcs, her role varies. In her primary arc, she evolves from a determined but rigid competitor to a more balanced leader. In the Kandagawa Jet Girls’ arc, her team loses the initial river ownership race, diverging from their victory in her own storyline. During the Grindcore arc, she positions Dress as rivals to correct Kamui Kurenai’s destructive obsession with victory, delivering a strategic defeat to foster Kamui’s realization about healthy competition. Her development continues in the OVA, where she collaborates with other teams on a jet racing promotional video. After her initial rigorous training montage submission is rejected for being intimidating, she accepts feedback and supports alternative approaches, showcasing increased flexibility and collaborative spirit despite the final product differing from her original vision.

Her interactions further illustrate her multifaceted nature. She maintains a respectful but distant rivalry with Rin Namiki, first encountered during a fishing dispute resolved through a race. With teams like Unkai Surfers, she expresses bewilderment at their fixation on Manpuku’s shinobi background. Her dynamic with Grindcore shifts from antagonism to mentorship following their defeat. Throughout all media, her actions consistently reflect a blend of aristocratic poise, underlying warmth, and a gradually deepening understanding of responsibility beyond personal prestige.
