After transmigrating into the Uma Musume world, instead of becoming a trainer, I somehow unlocked the [Horse Girl Treatment System] and ended up as a doctor?! To level up my medical skills and become a legendary healer, Lin Anran activated a system quest-only to find out he had to turn into a horse girl and win races?! And the characters he could transform into were... [Platinum · Centaurea] and [Margaret · Nearl]?! Wait-since when do Pegasus count as horse girls?! But the first leg of the Triple Crown, the Satsuki Sho, was already over-no chance at a perfect Classic Triple Crown now. All or nothing! After transforming into Platinum, he set his sights on the unprecedented [Irregular Triple Crown]!

"The world is always wrong." After surviving high school with my cynical wit and a complete lack of romantic progress, I-Hikigaya Hachiman was ready to live a peaceful, uneventful life. No youth, no drama, no forced social interaction. That dream came to a crashing halt when I somehow woke up in a world where horse girls-yes, literal girls with horse ears and tails-race professionally while chasing their dreams. And apparently... I'm now their trainer. Me. The guy whose idea of teamwork is "doing everything myself to avoid dealing with people." Special Week smiles at me like I'm her hero. Tokai Teio asks for advice like I have wisdom. Mejiro McQueen demands a training plan like I know what I'm doing. Spoiler: I don't. But every race pulls me deeper. Every tear, every laugh, every finish line crossed... I start to understand these girls. Maybe... just maybe... This world isn't as wrong as I thought. A loner, a realist, and a former Service Club ghost becomes the heart of a new team. This is the story of how I, Hikigaya Hachiman, became the most reluctant-and possibly the most effective-Uma Musume trainer this world has ever seen.

Tracen Academy is in shortage of trainers, thus they look further a field for new faces to help their Uma's debut, That's where you Come in Y/N L/N a Young track and field runner straight out of college, A determined kid with grit and a heart of gold.
