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!!!"

Kuroha is reborn in the world of Uma Musume, where the greatest racetracks double as school stadiums and legends are made under stadium lights. He's late to the party: superstar Oguri Cap has already moved up to the prestigious Tracen Central Academy, and future icon Tokai Teio hasn't arrived yet. Kuroha is stuck coaching in the sticks-until he recruits raw talent Fujimasa March and starts steamrolling the local circuit. With smart training, brutal discipline, and a chip on his shoulder, Kuroha sets his sights on the only stage that matters: The Top!

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.

Each team represents the core values of the trainer and their Umamusumes History, anything can come true Rigil - A team that's stacked on historical champions. 7 Crown winner, Symboli Rudolf, 2 Triple Crown Winners, Narita Brian and Daring Tact Now, with Spica on the hopes of winning it with new blood, another team will go even further for the trophy And now, a new team shall take over, a new generation of Umamusumes

Ten years after the age of legends, the world of racing has moved on-at least on the surface. In 2030, victories are measured by data, legacies are dissected by media, and expectations are placed long before a runner ever steps onto the track. The past still exists, but it no longer inspires hope-only comparison. Y/N Kei is a trainer with no history, no known background, and no ties to the racing world. He appears quietly, registers legally, and takes charge of a small, fractured roster-some burdened by family expectations, others completely free of them. Among them are siblings born from a name the world refuses to forget, and others who run simply because they want to.

Y/N, not knowing how or even why he got the job in the first place, arrives at Tracen Academy's Tokyo Branch, becoming one of many trainers to help the students chase their dreams of going big Faced with already having no experience in this field, he has to help one that wants to go big even though they know this trainer has no capabilities in doing so
