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]! Then, switching to Near Light, he stormed the dirt tracks of the American Triple Crown, charging straight into the Dream Cup to face legends like Secretariat and Man o' War! Between all the winning, his medical career somehow took off too. "Hey... can you promise to treat only me, forever?" "I never enjoyed racing before... but for Dr. Lin..." Lin Anran: "Gahhh, stay away from me!!!"

As a child Y/N loved watching races not just for speed but for the decisions behind every victory and now as a newly licensed trainer at Tracen he must scout Umas himself while navigating a campus full of strong personalities, unexpected chaos, and growing bonds that turn training into a journey of teamwork, comedy, and friendship.

After another failed confession, Taichi decides that he has enough on love and refuses to find love again. Until he was forced to enroll Tracen Academy as the only male human student by the government thus becoming the prey of the horse girls who wants to find a love partner for live or breeding partner or in Agnes Tachiyon case, experiment subject. How will he survive in the academy full of horse girls?

In a world where only female horse girls known as Umamusume exist, a sudden anomaly appears. a male horse also known as Umamusuko. Born with the blood of champions and the heart of a runner, Y/n L/n, the first and only Umamusuko, enter Tracen Academy, a school built to train future legends of the track. With dreams burning brighter than the morning sun, you'll run not just for victory, but for your place in a world that never expected you.

Being a Trainer at Tracen Academy was supposed to be a chill, quiet job. But when you're Y/N-a caffeine-fueled, chaos-loving, ultra-laidback dude with zero filter and way too much energy-you somehow become the biggest storm to ever hit the racetrack. Assigned to the underdog team Starhoof, a wild mix of misunderstood, quirky, and overly competitive Uma Musume, Y/N is determined to help them rise to glory... if he doesn't get fired first for riding a cardboard horse down the hallway or accidentally calling Gold Ship "Goofy Ship" in front of the media. Between dealing with rival trainers, late-night training shenanigans, heartfelt pep talks under the stars, and horse girls maybe catching feelings-Y/N's about to find out that sometimes, you don't chase dreams. You race toward them. And in his case? Probably while yelling "YEEHAW!" in a bathrobe.

Umamusume × Male Reader He bet everything on one race. He lost. Now, drowning in debt, a washed-up gambler and old teenager named Y/N is given one final, insane chance at redemption: manage a team of five chaotic Umamusume. The track is his new casino. Every race is a high-stakes wager. And his only assets are his frayed nerves and a team that's as likely to cause a disaster as they are to win one. Welcome to the madness between Y/N and his trainees...
