Description
Tazuna Hayakawa fulfills the role of secretary to the principal at Tracen Academy, handling administrative tasks, enforcing school regulations, and providing support to students and staff to foster a positive learning atmosphere. Though presenting as human, she exhibits remarkable running speed, effortlessly catching horse girls who break curfew—even top sprinters like Taiki Shuttle. She achieves this instant acceleration without visible strain, often while carrying documents or maintaining difficult postures.

Her appearance consists of a green uniform, matching hat, and yellow necktie. She has dark brown hair cut short in the front and long in the back, tied with a yellow bow. Standing 166 cm tall, she keeps her weight and precise measurements private. The consistent wearing of her green hat and uniform, which conceal her ears, fuels speculation about her true nature.

Personally, Tazuna remains consistently polite, gentle, and approachable, greeting students daily with calm composure. Yet, she demonstrates firm strictness when upholding rules, intervening decisively in disputes or misconduct. She celebrates positive events by cooking rice in a clay pot and enjoys watching films, comparing the anticipation before a movie to the excitement before a race. Her training advice emphasizes balanced growth, though some trainers find this approach unreliable.

Significant details suggest a connection to the historical racehorse Tokino Minoru. They share a birthday (May 2), and her uniform's color and design echo jockey silks. Tokino Minoru achieved an undefeated record of 10 wins before dying at age three from tetanus complicating a sand crack in his right front leg—a detail paralleled by Tazuna’s consistent placement of a watch on her right wrist ("toki" meaning "time"). She shows acute concern about injury-prevention equipment delays and frequently warns students about racing risks. Her surname "Hayakawa" incorporates "excellent horse" (駿), while her given name "Tazuna" (たづな) means "rein" in Hiragana. Tokino Minoru’s owner led a film company, aligning with Tazuna’s love of cinema. She references watching "Phantom Horse Girl," a film echoing Tokino Minoru’s legacy, and mentions fond memories of the Kyodo Tsushin Hai race, now commemorated as the Tokino Minoru Kinen.

Her relationships include a close, casual friendship with Maruzensky, sharing drinks and banter outside work. Legendary horse girls like Symboli Rudolf and Saint Lite treat her with familiarity and trust; Saint Lite uses the affectionate nickname "Tazuna-chan." She mediates student conflicts, as seen in spin-off media like "Umayuru."

Across the franchise, Tazuna appears consistently: guiding Special Week on her first day and delivering race news in Season 1 of the anime; announcing Tokai Teio and Mejiro McQueen’s rankings in Season 2; and welcoming students in Season 3 and the "Road to the Top" ONA. In "Cinderella Gray," she serves as narrator and assists Symboli Rudolf (acting principal), instructing security to protect Oguri Cap from reporters. In comedic spin-offs like "Umayon" and "Umayuru," she reacts to property damage with subtle anger and mediates arguments.

Within the game, she functions as a navigator, offering training advice and explaining race outcomes. Her Support Cards reduce stamina loss and increase motivation during training. Inviting her on outings reliably restores a horse girl’s health, though declining provides stamina skills at the cost of her support. She appears in gacha animations as the "green devil," playfully teasing players before rare character reveals. Principal Yayoi Akikawa’s appearance in this role guarantees a high-rarity draw.

No canonical confirmation exists regarding her being a horse girl or Tokino Minoru’s reincarnation, maintaining franchise ambiguity. Grass Wonder, descended from Tokino Minoru’s sister in real life, shares no acknowledged familial ties with Tazuna in the series. Her background beyond her role and implied connections remains unexplored.
