Narita Brian, a Tracen Academy high school student and student council vice president, cultivates an enigmatic presence defined by her solitary dedication to racing. Her striking appearance—long dark gray hair secured by orange-and-white cords, sharp yellow eyes, and a nose bandage mirroring a racehorse’s shadow roll—hints at her relentless focus. She habitually chews a homegrown stem and dons asymmetrical leggings adorned with oversized metal horseshoes, merging rustic tradition with unpolished edge. Her aloof, terse communication style reinforces a lone-wolf reputation, yet contradictions emerge in her private struggles. A fraught rivalry with older sister Biwa Hayahide fuels her drive to surpass familial expectations, though secret admiration surfaces during vulnerable moments, such as aiding Hayahide post-injury. Despite rebuffing sentimentality, she redistributes vegetable care packages from her family’s liquor store to peers, masking reluctant generosity beneath curt dismissals. On the track, her racing persona mirrors the real-world Narita Brian’s "Shadow Roll Monster" legacy—a powerhouse dominating mid-to-long distances via explosive techniques like "Last Leg" and precision "Hurricane Turns." Joining Team Sirius after clashing with trainers, she grapples with existential doubts about victory’s purpose, slowly embracing teamwork without sacrificing her primal hunger for competition. Peers oscillate between wariness of her intensity and quiet reverence for unexpected kindnesses, like mentoring juniors or enforcing council discipline. Her rivalry-friendship with Hishi Amazon thrives on mutual respect, their bond forged through shared drives. Beyond racing, she fumbles in the kitchen, rejects vegetables (except carrots), and harbors hidden softness for owl cafes and childhood stuffed animals. As vice president, her casual neglect of duties provokes exasperated searches by council president Air Groove, yet crisis moments reveal latent leadership instincts. Design cues—a torn jacket, sacred rope accessories—symbolize her fusion of raw power and heritage, while seasonal wardrobe shifts hint at evolving self-awareness. Backstory echoes of injuries and resilience parallel her fictional battles to sustain peak performance. Her arc traces a jagged path from isolation to guarded connection, balancing a racer’s ferocity with flickers of empathy that quietly galvanize allies. This duality cements her legacy: a storm of competitive hunger tempered by unspoken loyalty, challenging others to look beyond the shadow roll’s barrier.
