(A coming-of-age story with a system)

There is a team in the NBA that makes its own fans' blood boil and makes its opponents tremble with fear. That team is the Boston Celtics, who once created the miracle of winning 10 championships in 11 years and also have the most championships. However, since Larry Bird retired, the Boston Celtics have been in decline and are mired in a quagmire!

Cardinal Auerbach was searching for Bird's successor, accumulating a wealth of promising small forwards, but none of them were Bird. Forget leading the team back to the top, they couldn't even make the playoffs... until this man appeared...

That day, Wada Ryuji, Ikezoe Kenichi, who had traveled to the world of Umamusume for some time, and the younger Mr. Imami Ryuri gathered again to discuss their discoveries over the past few days. Wada Ryuji: I'm not sure if you will believe this, but I found Hao Opera in Tresen Academy. But she has changed so much that I don't recognize her. In my impression, even if she became a horse girl, she wouldn't have such a personality. Ikezoe Kenichi: Don't mention it, just be happy. I also met the Golden Master and the East Business Reform. The president even asked me to be their trainer. I'm going to suffer again. I only wanted to be [Xu Shi Ziqian]

Beast running back. From mixed martial arts to rugby, from an unknown rookie to a superstar who swept the league, from a layman who knew nothing to a feared beast... He left countless legends on this court and became a myth that changed the sport. However, the creator of all these legends said innocently at the beginning of the story: Football, what is that? I'm not really a football player, really.

I've traveled through time and space as a horse girl named Barbatos. I could have shot to fame at the League of Legends World Championship, but now, thanks to the system, I can only tearfully become Japan's top horse girl. As for my lack of talent as a horse girl? No problem! If I can't outrun others, I can always sprint. Huh? Even with sprint, I can't catch Silent Suzuka? Then I'll get Justice and Glory, Phantom Soul, and enchant my boots with Predator. Honestly, my hometown is quite high up, so a bit of highland blood isn't too much of a stretch, right?

Due to some accidents, the goddess brought her to the world of horse girls. Although she doesn't know what to do, she just needs to follow the goddess' disguised system, right? After being lectured by the goddess for a long time, the girl finally stepped onto the track, but... "Oh no! There was an accident with contestant 8's gate!" "He bumped into it!" "I'm so upset!" ==============[You have our genes, right?] Isn't that great? [Well...] ​​Hmm? After turning around, she saw several tall horse girls (relatively speaking). You...what do you want to do? "After all, Z-chan is an adult..." "It's legal anyway!" Don't come over here! ! ! ==============

"Horse Girls" are born to run. They have "tails and ears" on their bodies and "superhuman running abilities". They are simple and kind "girls".

They inherited names and souls from other worlds, gathered at the "Tracen" Academy, and kept running in the "Shining Star Series", striving towards the finish line called "dream".

But such a road is destined to be bumpy.

If the timeline remains the same, the reed-haired monster who regretted missing the classic triple crown, the white lightning who was forced to retire due to injuries, the dark assassin who had a happy name but was not blessed... these will happen again.

After traveling to this world and becoming a trainer, Kitahara is determined to create a better world for horse girls.

"My biggest dream is for you to run carefree on any field."

[No system, training, competition, competition + daily life]

After being murdered, Mu Xuan entered the body of Ma Niang. Miraculously, the two souls merged. Black hair, black clothing, golden eyes. A figure as ethereal as the night sky frequently appeared at the racecourse. No one knew her name, no one knew her identity, but her all-consuming, terrifying power left an indelible memory in all the Ma Niangs. "We must find her. Disregarding the rules and participating without permission is sheer lawlessness." The central government issued an ultimatum. The racecourse's security was impenetrable, yet the black phantom could not be stopped. Thus, the race [Wind and Forest]

With neat, short silver hair and eyes that sparkled like stars, she always ran with everything she had on the track.

No lineage. No talent. No one held any hope for her.

“Honestly, as a trainer, I see no future for this girl as an Umamusume. For her own good, I hope she gives up soon.”

The seasoned trainer delivered an ultimatum: if she couldn’t produce results, she would have to drop out.

However, in the world of Umamusume, nothing is absolute.

“I never thought an Umamusume like her could win a G1.”

“How is that possible? She shouldn’t have any talent at all!”

“Run! Let us witness this dream!”

Some called her “The Successor of the Grey Legend.” Others called her “The Trickster Who Soars Through the Night Sky.” But the name by which she was most known and sung about was “The King Slayer.”

Taking back thrones, toppling champions—she transcended bloodline and aptitude to stand at the pinnacle of all Umamusume. The world would shine brilliantly because of her.
