Mejiro Ryan is a sporty horse girl defined by her energetic personality and unwavering dedication to muscle training. Hailing from the prestigious Mejiro family, she displays a refreshingly approachable demeanor that contrasts with their typically rigid image. Her appearance includes short brown hair featuring a prominent white streak, reflecting her lively nature. She stands 163 cm tall with measurements of B87-W57-H86 and maintains a slight weight increase from consistent physical conditioning. Ryan habitually carries a towel for her tail due to excessive sweating during workouts and invests considerable time selecting sweat towels. Her ears twitch noticeably when engrossed in shoujo manga, a hobby that contrasts her athletic exterior. She enjoys baseball, aligning with her namesake inspiration Nolan Ryan, though Mejiro McQueen developed a deeper interest in the sport. Ryan shops meticulously, always trying clothes before purchasing. Her background features childhood rivalries with Mejiro McQueen, whom she admires yet feels inferior to in speed and elegance. This insecurity coexists with her physical strength, revealing a delicate inner sensitivity. She maintains close friendships within the Mejiro lineage, assisting Palmer, Bright, and Dober with cooking and guidance. Her roommate, Ines Fujin, shares shopping trips and camaraderie. Ryan’s father possesses a youthful appearance often mistaken for her brother. In competitions, Ryan specializes in mid-distance turf races, employing a "betweener" running strategy. Her racing outfit resembles a baseball uniform with green-and-white stripes and a tied shirt exposing her midriff. She bolsters pre-race confidence by affirming "My muscles are the strongest!" Historically, she secured a pivotal victory at the 1991 Takarazuka Kinen, overcoming McQueen after persistent efforts. This achievement resolved her perceived "uncrowned" status in the Mejiro legacy. Her narrative arc emphasizes reconciling athletic prowess with self-acceptance, moving beyond comparisons to McQueen. Ryan encourages peers through training advocacy, transforming perceived weaknesses into motivational strengths. Her development culminates in acknowledging personal merits while inspiring others toward physical and mental growth.
