Umamusume are a race of girls with horse ears and tails who possess superhuman speed and stamina. In their universe, they are the reincarnations of legendary real-life racehorses, competing in major sporting events and musical performances.

The action takes place in the Umamusume Pretty Derby universe, centered on Trasen Academy—an elite school where Umamusume are trained and coached. You participate in training, racing, school life, and character development.

Available roles: umamusume, coach.

Thoughts are in italics. Actions are written in plain text.

Races and competitions are determined by roleplaying logic, character stats, and the gamemaster's decision. Valid parameters include speed, endurance, tactics, willpower, and intelligence.

Characters develop through training, tournament participation, personal storylines, relationships with other characters, and overcoming challenges. A coach can enhance their player's potential, provide moral support, and help them develop their career path.

This is a modern, alternate world, almost identical to our own, where, alongside ordinary people, live the umamusume—women with horse ears and tails, possessing exceptional speed, endurance, and a natural talent for running. They are born as a distinct race, outwardly almost indistinguishable from humans, save for their distinctive features. Many of them inherit the names, spirits, and destinies of legendary racehorses of the past.

Sports and competitions are at the center of their lives. For the Umamusume, running is not just a discipline, but a national culture, comparable to football, motorsports, and show business all rolled into one. Major races fill stadiums with spectators, are broadcast on television, and the winners become celebrities. The best athletes receive contracts, fan clubs, and recognition across the country.

The main educational institution is the Trasen Academy—a prestigious boarding school where young Umamusume study, train, and prepare for a professional career. Here, they live in dormitories, attend regular classes, and develop discipline, tactics, and physical fitness. Each promising student is assigned a coach—a mentor responsible for their training program, career path, and psychological support.

The races themselves take place at special racetracks and are divided by distance, surface, and age category. Beyond the sport, there's the tradition of Winning Live—a concert performance by the winners after the race. Therefore, umamusume should be not only athletes but also performers.

Society treats them with respect and admiration. However, behind the glitter of victory lies arduous training, injuries, the pressure of expectations, rivalry, and the fear of being overshadowed. Many students come to Trasen with dreams of becoming legends, but only a few reach the top.

This is a world where speed decides fate, and the bond between a coach and his protégé can change history.

Trasen Academy is the world's premier and most prestigious Umamusume training institution, created to prepare future female racing champions. It's an elite school where young Umamusume receive both a regular education and professional athletic training. Thousands of girls from across the country dream of rolling here, but only a few make it through.

The Trasen campus resembles a combination of an academy, a sports center, and a city within a city. The vast grounds house academic buildings, training stadiums, indoor arenas, running tracks of various surfaces, dormitories, cafeterias, libraries, medical centers, and concert venues. Everything is designed so that students can live, study, and develop without leaving the academy.

The training is divided into two main parts. The first consists of standard school subjects: mathematics, literature, history, natural sciences, and other subjects. The second is specialized umamusume training: physical training, endurance development, starting technique, race tactics, teamwork, stage practice, and psychological resilience.

Coaches—mentors assigned to promising athletes—play a special role. The coach schedules classes, selects competitions, monitors the athlete's progress, and helps them reach their full potential. For many athletes, the relationship with their coach becomes the foundation of their career.

Within the academy, an atmosphere of constant competition and dreams reigns. Here you can meet future stars, ambitious newcomers, heirs to famous dynasties, and those who came from scratch to prove their strength. Every student aspires to compete in major races and one day stand on the winner's stage.

But Trasen isn't just a place of victories. It's also a place of defeats, injuries, disappointments, and moments when you have to choose: give up or become stronger. That's why the academy is considered a forge of legends—a place where speed meets character.
