Mihono Bourbon is a student at Tracen Academy and a supporting character in Uma Musume: Pretty Derby - BNW no Chikai. She is an umamusume known throughout the school by the nickname Cyborg, a label that reflects both her mechanical running style and her unusual personality. Her background is rooted in an upbringing of intense, solitary training from a very young age; this constant focus on practice meant she had few opportunities to interact with others, which shaped the distant and robotic exterior she presents to the world. She processes her environment through the lens of data, protocols, and directives, carrying out her objectives with an expressionless demeanor and speaking in clipped, emotionless sentences. Despite this cold surface, Mihono Bourbon does possess genuine feelings and emotions, but she has difficulty recognizing and expressing them, leading to occasional moments where her true warmth glitches through her otherwise machine-like composure. Her core motivation is to pursue the Triple Crown, a goal she approaches with the same methodical precision she applies to everything else, breaking down the monumental task into manageable steps through relentless, disciplined effort. In the story, she serves as a quiet but capable presence among her peers, fully dedicated to supporting others and encouraging them to work hard, even if her advice comes across as blunt or impersonal. Her key relationships revolve around this supportive role, as she interacts with fellow students not through casual friendship but through a shared commitment to improvement and teamwork. Over the course of her appearances, Mihono Bourbon shows subtle development as she begins to confront the feelings she keeps locked away, gradually learning that there is value in connecting with others on a more emotional level. Her notable abilities on the track are formidable: she is an elite front-runner who excels at medium-distance races, able to maintain a constant, crushing high speed while leading the pack. Her strategic mind and ability to stay calm under pressure allow her to execute race plans with near-perfect precision, reinforcing her reputation as something more than an ordinary horse girl.
