Special Week, a determined and optimistic horse girl from Hokkaido, was adopted by a human mother following her birth mother’s death from childbirth complications. Raised in rural isolation from other horse girls, she cultivated an earnest demeanor and relentless work ethic, fueling her enrollment at Tracen Academy to honor both mothers by aiming to become Japan’s top competitor. Her journey intertwines naivety with resilience, as she navigates social and academic hurdles through study sessions with peers like Silence Suzuka and Tokai Teio, while uplifting others with heartfelt encouragement. Her appearance features hazelnut-brown hair accented by white bangs, rose-purple eyes, and a racing outfit blending white-and-pink idol aesthetics with a four-leaf clover motif symbolizing four G1 victories. Standing 158 cm tall, she experiences minor weight shifts from pre-race nerves and exhibits unique traits like acute hearing for cooking noises and an emotionally expressive tail during games. Key relationships shape her growth: roommate Silence Suzuka evolves from idolized mentor to emotional anchor, their bond tested by Suzuka’s injury and subsequent racing hiatus. Rivalries with Seiun Sky, King Halo, and Grass Wonder reflect real-life race dynamics, marked by triumphs like her 1998 Japanese Derby win and alternating defeats. Familial ties extend to daughters Cesario and Buena Vista, and great-granddaughter Daring Tact, showcasing her enduring legacy. Her arc centers on overcoming self-doubt, balancing concern for Suzuka’s recovery with personal ambition, culminating in a decisive Japan Cup victory against Montjeu. Subsequent races against Tsurumaru Tsuyoshi and T.M. Opera O highlight persistent challenges, while her adaptability shines through dietary discipline to manage weight—contrasting her fictional food enthusiasm with the real horse’s documented traits. Quirks include gourmet critiques, heartfelt letters to her mother, and blindfolded milk-tasting skills. Occasional Hokkaido dialect during home visits adds cultural texture. Her narrative mirrors historical races, such as paralleling jockey Yutaka Take’s Derby milestone, weaving equine legacies into her personal journey and underscoring the franchise’s blend of fiction and homage.
