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."

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.
