Xu Zong accidentally traveled to Tresen Academy and became Spica's trainer, activating the diary system. He earned rewards by keeping a daily diary about his horse training. However, Xu Zong had no idea his diary would be read by horse girls like Tokui Zhou, Narita Road, Zhuo Fu, Donghai Emperor, and Northern Xuanju. Mebiro McQueen: "Wait, the fat horse in the diary, it's not talking about me, right? How am I fat?" Emperor of the East Sea: "Why does everyone know that I like to drink honey?" Narita Road: "Who's the crybaby? I... Even if I win, I won't cry, probably!" Excellent Quality: "Why do you say I'm a bronze medal collector? Woo woo woo, trainer, you're so mean." Northern Black Horse: "What's an assist card? Beware of the Hammer? Who is the Hammer!" Satomi Mitsuru: "Huh? Why do you call me Brother Diamond?" Teju Zhou: "Who is Teju Dai? Wait, do I have a sister?" Airi Hayabusa: "Is Shima an isotope in a parallel world?" Xu Zong's diary is full of strange things, and the horse racing girls are all looking forward to it. As the content becomes more and more, the horse racing girls learn more about isotopes in parallel worlds.

"Do you know the story of the Star Raiders?"

"I don't know. Tell me."

“Very unique.”

"Ah? Senior, you're already keeping me in suspense."

"Haha, you have to figure out the rest yourself, right?"

…

"It's that time of year again. At the end of the year at the Nakayama Racecourse, the passion of the horsewomen and the enthusiasm of the spectators are enough to dispel the cold. Yes, the G1, the Arima Kinen..."

…

"Hey, all the horse girls are standing on the track. Who will win the Arima Kinen this time?"

Feeling the gentle caress of the wind, standing on her last track, she was not as calm as before. Looking at the many familiar and unfamiliar faces, a thought came to her mind.

"Everyone! Please look at my gesture! This is the last foot from the last star!"

Open your eyes and enter the world of Equestrian Girls. Born as Rudolph's symbolic sister, my goal is to witness the journey of all horses in eternity. I am fortunate to have so many horses, and I hope to create an era where all Equestrian Girls can be happy.

...

Every horse girl has her own wish, every horse has her own story, and every era has its own pride. Records are not static limits; constantly surpassing them is the inevitable choice. Life may be short, but being remembered is eternal—this is the time of eternity.

In Yamakaze City, a girl named Senriko is born with invisible red chains binding her legs, preventing her from running freely like other horse girls, but she always cherishes a longing for the world of horse racing.

What caused all of this? Is it possible to embark on my own path once again?

(The introduction is insufficient; please proceed to the main text.)

That year's Arima Commemoration was Oguri Hattori's retirement race, and she became a miracle. I saw Tamamo Cruz in the stands, sobbing uncontrollably; that image is etched in my memory forever. At that moment, I thought, if I could become a Uma Musume (horse racer), I would definitely participate and become a legend. Now the opportunity is before me, and I must consider whether this might be my only chance in this lifetime. I believe that Oguri Hattori's contribution to Uma Musume's current status is indispensable. Restoring Uma Musume's glory is our inescapable duty. ...

【Multiple Heroines】Just because I answered the question of a gentle older sister in my dream,

When the young man on the hospital bed opened his eyes again,

"From now on, he will be your trainer and she will be your horse girl."

Reporter: "How do you feel about becoming the world's number one horse racing girl?"

Xianli Xingguang: "Ahem, let's be low-key about this."

"Hey, Mi Yu! Stop pulling at me, my pants are going to fall off."

The reporter looked at the two men playing around and the many horse girls behind them. "So, how do you manage such a harmonious and friendly school life?"

Xianli Xingguang: "Impossible, absolutely impossible, Shura Field, stay away from me."

[Uma Musume Girl fanfiction, not actual horse racing]

In this world where humans and horse girls coexist, friction between nations has been smoothed away by the world's benevolence, allowing various bloodlines to continue. Horse girls from different bloodlines compete, rising to prominence, and here...

A gifted racehorse girl came to Treson Academy to study, carrying a vision to shine in the East.

"Senior, just you wait and see!"

Then……

"I am just me."

No longer burdened by the need for others' approval, her path no longer requires their approval or guidance.

Many years later, when he receives the "Lifetime Achievement Award", Yasui Makoto will recall the afternoon when he was knocked 10 meters away by a horse racing girl...

At the time, he had only been licensed as a Central Trainer for a few months, and because he seemed to lack experience, he was rejected by many horse girls.

After being rejected by a horse racing girl again, he was probably a little distracted. When he was crossing the road and waiting for the red light, he saw a child almost being hit. He rushed forward without thinking too much.

The child was rescued by him.

He was knocked away.

Not being hit by a car.

Instead, he was knocked away by a horse girl with short black hair, red eyes, and a black tail.

In order to meet the assessment requirements, he secretly trained himself based on his past life experience at a very young age.

Although he was hit while distracted, he adjusted his posture in time and was not seriously injured.

But the horse girl was obviously terrified.

“I’m so sorry! Are you not hurt…?!”

"My name is Northern Xuanju! I'm a new student at Central Tresen Academy this year! Please take care of me!

"I, I...anyway, I, I...I will be responsible for you to the end!"

At that time, the "horse racing girl" named "Northern Black Horse" said in panic.

[Some of the Uma Girls' identities and professions have been modified, and the world view has been expanded. Other than that, it is consistent with historical facts and will not affect the viewing experience of the original fans.]

[In the early stage, the northern black colt will join the team in the later stage of the Spring and Autumn Division. During this period, other famous horses will be considered, such as Xingmu and Su Daji]
