Sent Flying by a Racehorse Girl

Tokyo, Treisen Academy Affiliated Hospital, Neurology Examination Room.

Behind the desk, a brown-haired woman with long brown ears held a steaming cup of black tea in one hand and a brain X-ray in the other.

After examining the X-ray for a while, she looked across the desk. Her crimson eyes, patterned like window blinds, brimmed with unmistakable interest.

"Getting sent flying ten meters by a racehorse girl running at dozens of kilometers per hour, and all you have is a bruised soft tissue?

"Hoho, what an interesting constitution...

"Would you be interested in becoming one of my test subjects, Anjing-kun?"

Sitting across from her, the young man named Anjing Zhen shook his head rapidly without a moment's hesitation.

"I'm afraid I'll have to refuse, Doctor Agnes Tachyon.

"Besides the bruising, I don't have any other problems, do I?"

Setting the X-ray down, the long-eared woman named Agnes Tachyon took a sip of her tea with both hands, narrowed her eyes, and curled her lips into a smile.

What a fascinating young man...

A few months ago, the Academy announced this year's Central Trainer examination results.

As usual, not many people had passed. But the top scorer's results had caused quite a stir in the industry.

Anjing Zhen, eighteen years old, had graduated from the Trainer Academy just last year. Apart from the vocal performance portion of the singing and dancing exam, he had scored full marks in everything.

Agnes Tachyon had been astonished for quite some time, too.

She had retired very early, but she had once been a racehorse girl herself, so she knew how difficult it was to earn a Trainer's license.

The Central-level exams were especially tough. It was no exaggeration to say that passing them was a one-in-ten-thousand feat.

And most Trainers who earned their licenses were over thirty. Those in their twenties were few and far between, let alone someone as unbelievably young as eighteen.

She had immediately wanted to find an opportunity to get a few slices from Anjing Zhen to study.

Brain slices, preferably. They might even help advance some of her research.

But between seeing patients at the hospital every day, doing research, attending discussions, and teaching at Central Treisen Academy, she hadn't found the chance.

She hadn't expected him to walk right into her office today.

The reason he'd come was just as she'd said: he'd been sent flying after a racehorse girl hit him at dozens of kilometers per hour.

Normally, someone who got hit hard enough to be thrown through the air would suffer at least internal injuries or broken bones. Yet Anjing Zhen had only mild bruising.

And according to the racehorse girl who had brought him in, he'd gotten back to his feet on his own after the collision and looked completely fine.

That meant his physique was just as unbelievable as his intelligence.

Now, what excuse could she come up with to give this interesting little guinea pig a slicing operation? Hohoho...

She took a sip of tea and pretended to consider his condition as her thoughts raced.

Under the gaze of those crimson eyes, Anjing Zhen felt inexplicably uneasy. A chill ran down his spine.

He'd heard a rumor about this racehorse girl. Apparently, she was very keen on conducting human experiments.

The rumor had never been confirmed, but he was obviously fine, and she was putting on an act of pondering his condition. He wasn't about to believe she didn't have some ulterior motive.

He could read X-rays not only because becoming a Central Trainer required sufficient medical knowledge, but also because in his previous life, he'd been an "extreme acrobat."

"Extreme Skills" was a relatively new sport, part of the larger category of extreme sports.

It brought together all kinds of difficult moves from other disciplines, and even pushed them to a higher level of difficulty.

For example, forward and backward straight-body twists from gymnastics, flying armbars from martial arts, and double-spinning lotus kicks from capoeira.

These moves were also combined to create events that were more spectacular and challenging.

The dangers of the sport went without saying. In his previous life, despite his exceptional natural talent, he'd had his share of mishaps. Then, during an aerial performance, an aircraft accident had sent him to this world.

That was when he discovered that this world was rather unusual.

There were no horses here. Instead, there were "racehorse girls."

They had long ears and horse tails, and were blessed by divine beings known as the Three Goddesses. Their physiques far surpassed those of humans, and they were born with extraordinary talent.

Their leg strength was especially remarkable. On average, they could run at sixty kilometers per hour.

They loved to run, too, and an institution had been established specifically to train them: Treisen Academy.

By coincidence, his parents in this life had both come from Treisen Academy. His father was a local Trainer, while his mother was a retired local racehorse girl.

He hadn't hesitated much before deciding to become a Trainer for racehorse girls.

For an "extreme acrobat," the greatest dream was to challenge the limits of the human body—or to witness a performance that pushed those limits to their utmost.

Racehorse girls looked like humans, but had far greater physical abilities. They were exactly the kind of beings that spoke to his dream.

He wanted to see just how far these creatures in this world could go.

He also wanted to find out whether, by watching them perform, he could surpass the limits of being human himself.

With that hope, and drawing on the memories and skills he'd gained over two lifetimes, he was accepted into the Trainer Academy straight out of middle school.

As soon as he graduated, he passed the exam to become a Trainer at Central Treisen Academy. A few months ago, he'd left his hometown for Tokyo.

It was difficult for a novice Trainer to sign a contract with a racehorse girl. Usually, they had to spend some time learning from an experienced Trainer before gradually setting out on their own.

Anjing Zhen didn't think he needed to do that.

To become a professional extreme acrobat, he'd had to develop all kinds of abilities. Calling him the best in the industry would be an exaggeration, but he was certainly among the top performers.

On top of that, he'd been learning the professional side of training from his parents from an early age. He was confident he could guide a racehorse girl to become talented and outstanding.

Other people, of course, wouldn't see it that way. So during his first few months in Tokyo, he'd tried approaching a lot of racehorse girls, only to be turned down every time.

He'd been rejected again that day, and perhaps that was why he'd been distracted. While waiting for a red light, he'd seen a child nearly get hit by a car and rushed over without thinking.

He saved the child. Then he was sent flying.

It wasn't a car that had sent him flying, but a short-haired black racehorse girl.

Fortunately, he'd faced situations requiring such extreme reflexes in his previous life. Acting on instinct, he'd adjusted his position in time and escaped with little harm.

He'd meant to leave right away, but the racehorse girl was clearly shaken. She kept apologizing after hitting him and insisted on bringing him to the hospital for an examination.

He'd tried to refuse a few times, but couldn't get through to her. She was so stubborn that she looked ready to follow him everywhere if he didn't agree. In the end, he had no choice but to come to the hospital.

He hadn't been hurt when he was hit, only to end up in the clutches of the strange racehorse girl Agnes Tachyon when he came to the hospital.

And now she looked like she wanted to slice him up. As Anjing Zhen struggled with a headache, he quietly tried to figure out how to get away.

After studying Anjing Zhen for a long while, Agnes Tachyon finally spoke, slowly.

"Your other problems... It's hard to say for now.

"If something turns up in a few days, that could be troublesome.

"So, I recommend that you stay here for a while, Anjing-kun, so we can keep an eye on you.

"Also, you'll probably need to undergo some brain surgery before we can be sure..."

Anjing Zhen's scalp prickled. He immediately realized that the racehorse girl in front of him really was planning to slice him up.

Before he could refuse, the neurology examination room door burst open with a bang.

A short-haired black racehorse girl charged in.

As she burst through, the handle let out a grating creak, and a large chunk of the door came off with it.

"B-brain surgery?! I-is it really that serious?!"

As Agnes Tachyon stared in surprise and Anjing Zhen looked on in shock, the black-haired racehorse girl glanced at the door handle she'd ripped off, then at the hole in the door.

"S-sorry! I-I was too careless..."

She hastily hid the door handle behind her back and bowed deeply.

"D-Doctor Agnes Tachyon, hello!

"M-my name is Kitasan Black! I'm a new student at Central Treisen Academy this year! It's nice to meet you!

"I-I... Anyway, I-I'll take responsibility for everything that happens to Mr. Anjing!"

In short, I watched the new trailer for Gray Cinderella, and I couldn't hold back the urge to write another Uma Musume novel.

Also, because of my lack of experience with my last book, I didn't get to write many of the stories I wanted to tell. I've wondered many times whether I should write another one.

Anyway, I decided to write it.

I've already submitted it for an internal signing review. If you like Uma Musume, sports competition, or everyday school-life stories, feel free to add it to your collection.
