The 4:30 AM mist over the Tracen Academy training grounds was so dense it tasted like wet iron.
Satou Kazuma sat slumped against the wooden support pillar of the outer dirt track, his legs stretched out straight on the freezing ground.
In his left hand, he held a plastic whistle attached to a faded lanyard; in his right, a digital clipboard displaying a series of complex, hand-drawn vector diagrams.
His eyes were bloodshot, his throat burned from the damp air, and his hamstrings felt as though they had been replaced with rusty piano wires.
“Trainer!
Look!
If I hop on my left foot three times and then kick, I look like a majestic crane!”
Twenty yards away, Haru Urara was currently executing a series of completely erratic, asymmetrical leaps across the white starting line.
Her pink twin tails were bouncing violently, her short ears twitching to an internal rhythm known only to her, and her uniform was already dusted with red clay from a fall she had taken roughly four minutes after arriving.
Kazuma let out a long, raspy breath, the steam blowing into the cold air like exhaust from a dying engine.
*Twenty-six years in this world,* Kazuma thought, closing his eyes briefly as a sharp cramp rippled through his calf muscle.
*I survived normal childhood illnesses, I survived high school entrance exams, I survived working double shifts at a convenience store to pay for trainer certification study materials.
I spent two decades building a completely normal, low-stress life in this universe.
So why am I out here, at an hour when even night-shift workers are going to sleep, subjecting my fragile human physiology to the training regimen of an apex predator?*
The cruelest reality of training an Uma Musume was that you couldn’t simply direct them from the sidelines with a stopwatch—not when the athlete in question possessed the attention span of a dandelion seed in a hurricane.
If Kazuma sat on the bench, Urara’s eyes would drift within ninety seconds.
She would notice a beetle on a wooden post, a cloud shaped like a dumpling, or a feather floating over the rail, and her pace would collapse into a meandering walk.
To keep her locked into a steady, rhythmic velocity, Kazuma had to be *in* the movement with her.
Which meant that every kilometer she jogged, he ran.
Every stride drill she executed, he demonstrated.
“Urara,” Kazuma called out, his voice a gravelly rasp.
“Get over here.
Stop being a crane.”
“Aww, but crane-style is super graceful!” Urara giggled, trotting over with small, light steps that barely made a sound on the dirt—a stark contrast to Kazuma’s heavy, boot-clumping limp.
She squatted right beside him, her chin resting on his knee, her big brown eyes looking up at him with utter, uncritical devotion.
“Are we doing the numbers again, Trainer?”
“Yes.
We are doing the numbers,” Kazuma grunted, forcing himself to sit up straight despite his lower back emitting a concerning *pop*.
He tapped the digital clipboard with his knuckle.
“Pay attention.
This is the geometry of fifth place.”
He brought up a bird’s-eye diagram of a standard eight-runner dirt field.
He had drawn the runners as color-coded icons: red for the hyper-aggressive pacesetters, blue for the elite stalkers, and a bright pink circle for Urara.
“Now,” Kazuma began, pointing a finger at the red icons clustered at the front.
“When the gate opens, what are these girls going to do?”
“They go *VRRRROOOOOOM*!” Urara yelled, mimicking a race car with her hands and nearly hitting Kazuma in the nose.
“Correct.
They go *vroom*,” Kazuma said, dodging the stray hand with practiced ease.
“They are high-ego, high-speed runners who believe they are destined for the cover of sports magazines.
They will expend sixty percent of their total oxygen reserves in the first four hundred meters just to prove a point to the cameras.
If you follow them, what happens to your bucket?”
Urara’s pink ears flopped flat against her head.
“The water spills out!
And then I get all floppy and my tongue hangs out!”
“Exactly.
Your stamina bucket dumps its entire contents into the dirt,” Kazuma said smoothly.
“So, when the gate opens, you do *not* chase the red icons.
You let them tear ahead.
You tuck yourself into this specific pocket right here—behind the third runner, slightly to the inside of the rail.”
He pointed to the sweet spot: the absolute heart of the middle pack.
“This is the slipstream,” Kazuma explained, his voice dropping into the precise, calculated tone he used whenever he was setting up a low-risk, high-reward scheme.
“The wind resistance is reduced by twelve percent because the girls in front of you are breaking the air.
The dirt kicked up by their hooves will hit your chest, not your face, as long as you keep your chin tucked low.
You stay in this pocket for eight hundred meters.
You don’t look at the crowd.
You don’t look at the sky.
You fix your eyes on the back of the jersey of whoever is in fourth place, and you count.”
“Count?” Urara tilted her head, her short ears twitching.
“Count what?
Carrots?”
“You count your own breaths,” Kazuma said, reaching out and gently tapping the center of her chest, right over her sternum.
“In for two strides, out for two strides.
*In-in, out-out.* Like a bellows.
If you hear someone screaming behind you, ignore them.
If you see someone passing you on the outside, let them go.
You are not racing them.
You are holding a lease on fifth place.”
Urara stared at the diagram, her brow furrowing in intense concentration.
For anyone else at Tracen Academy, being told to intentionally aim for the middle of the pack would have been a soul-crushing humiliation.
But to Urara, Kazuma’s voice wasn’t a limit; it was an anchor.
In a world that constantly demanded she be faster, stronger, and better than her nature allowed, Kazuma was giving her a quiet, safe, mathematically solid space where she was allowed to just *exist*.
“In-in, out-out…” Urara repeated softly, her small hands coming up to mimic the breathing pattern against her own chest.
She looked up at Kazuma, her eyes sparkling.
“And when we reach the last turn?”
“When we reach the last turn, the front-runners will be dying,” Kazuma smirked, a dark, satisfying grin spreading across his face.
“Their lungs will be burning, their legs will feel like lead, and they will start drifting wide because they used all their energy in the opening straight.
You don’t sprint.
You just maintain your *in-in, out-out*.
You cruise right past their tired, overconfident rear ends, cross the line in fifth place, collect our check, and walk away.”
Urara let out a gasping gasp of pure joy, clapping her hands together.
“Trainer, you’re like a ghost wizard!
A sneaky ghost wizard!”
“It’s not magic, it’s basic resource management,” Kazuma grunted, pushing himself off the pillar with a heavy groan that sounded like a breaking tree branch.
“Now, stand up.
We have to practice the slipstream drill.
Which means I have to run in front of you holding a plastic sheet so you can feel the air displacement.”
Urara scrambled to her feet instantly, her tail swishing in delight.
“Yay!
Plastic sheet game!”
Kazuma looked up at the grey, lifeless morning sky, letting out one final, quiet complaint to the universe.
*I could have been an accountant.
I could have worked in a quiet tax office in Osaka.
I hate my life.*
Then he looked at Urara, who was currently hopping in place to keep her legs warm, giving him the brightest, most unabashed smile in the entire prefecture.
Kazuma sighed, adjusted his green jacket, grabbed the blue plastic tarpaulin from the equipment crate, and set his feet in the dirt.
“Alright, torpedo.
On my whistle.
Keep your eyes on my back and count your breaths.
If you bump into me, no afternoon sweet potato.”
“Aye-aye, Captain!”
By three o’clock in the afternoon, the temperature on the secondary track had risen, turning the morning dampness into a muggy, clinging humidity.
Kazuma sat on the grass just outside the track boundary, his green tracksuit jacket unzipped to reveal a gray t-shirt soaked through with sweat.
His legs were stretched out, and he was methodically wrapping a roll of athletic tape around his left ankle.
His body was a tapestry of minor, low-grade athletic injuries—the inevitable price a twenty-six-year-old former indoor enthusiast paid for attempting to match the daily warmup volume of a teenage horse girl.
“Ow…
damn it…” Kazuma muttered, pulling the tape tight until his ankle clicked into alignment.
“Who designed human joints?
A single awkward step on an uneven patch of dirt and the whole structural integrity collapses.
It’s ridiculous.”
A few paces away, Urara was sitting on a low wooden bench under the shade of a ginkgo tree.
She wasn’t running, for once.
She was wearing her post-workout slippers, her feet dangling several inches above the ground, swinging back and forth in a slow, hypnotic rhythm.
In her hands, she held a worn, red plastic clipboard containing her official entry forms for the Harukaze Maiden Stakes.
The race was only four days away.
Up until now, the upcoming event had been an abstract concept—something mentioned in Kazuma’s diagrams or teased with promises of station ramen and sweet potatoes.
But seeing her name printed on the official regional race registry in black, indelible ink made the reality settle into the quiet air between them.
*Haru Urara — Class: Unranked Maiden — Weight: 41kg — Trainer: Satou Kazuma.*
“Trainer?” Urara called out, her voice unusually quiet.
Kazuma snapped the end of the athletic tape with his teeth and smoothed it down against his sock.
“What?”
“What if…” She paused, her fingers tracing the edge of the plastic board.
Her short ears dipped downward, casting tiny shadows over her forehead.
“What if the dirt at Kochi is different than the dirt here?
What if it’s super hard?
Or what if it gets in my eyes and I forget how to count?”
Kazuma stopped working on his ankle.
He looked over at her, noting the subtle tension in her small frame—the way her shoulders were pulled inward, the way her tail wasn’t swishing, but hanging limply between the wooden slats of the bench.
For all her boundless cheer, Urara wasn’t stupid.
She knew what people said when she passed the main grandstands.
She heard the quiet chuckles from the senior trainers, the whispered remarks from the high-tier runners who looked at her time trials like a comedy routine.
She pretended not to hear, drowning it out with her endless noise and laughter, but the weight of being the academy’s resident “hopeless girl” was a heavy thing for a pair of small shoulders to carry.
Kazuma didn’t offer a dramatic speech.
He didn’t rise, strike a hero’s pose, and declare that he believed in her with all his heart.
That wasn’t how their dynamic functioned.
Instead, Kazuma grunted loudly, pulled himself off the grass with obvious physical effort, and limped over to the bench.
He didn’t sit beside her; he simply stood in front of her, blocking the glare of the afternoon sun with his body, casting a cool, comfortable shadow over her.
He reached into his pocket, pulled out a small, metal object, and tossed it into her lap.
Urara blinked, picking it up.
It was an old, silver stopwatch—not the digital school-issue one Kazuma used on the track, but a heavy, mechanical pocket watch with a winding stem at the top and a scratched glass face.
“What’s this?” she asked, tilting her head.
“It’s my watch,” Kazuma said, resting his hands on his hips and leaning back slightly.
“My grandfather gave it to me when I passed my middle school exams.
It doesn’t track lap splits, it doesn’t calculate average velocity, and the second hand loses about three seconds every two days.”
Urara held the heavy metal disc in her small palms, feeling the faint, steady *tick-tick-tick* vibration radiating through the metal casing.
“Do you know why I keep it?” Kazuma asked.
Urara shook her head, her pink twin tails brushing against her shoulders.
“Because it doesn’t care how fast time moves,” Kazuma said, pointing a finger down at the watch.
“It just keeps ticking at its own pace.
It doesn’t try to beat the digital timers in the faculty lounge, and it doesn’t try to go faster just because the sun is going down.
It has one job, and it does it without making a fuss.”
He reached out, his hand settling gently on top of her head, right between her ears.
He gave her hair a brief, messy rustle—not a polite pat, but the rough, affectionate gesture of an older brother who had dragged her through a hundred small battles.
“Kochi dirt is just dirt, Urara,” Kazuma said, his voice steady, grounded, and utterly devoid of doubt.
“It’s the same brown stuff you fallen into fifty times this week.
And the girls running next to you?
They’re just kids in fancy silks who think running fast makes them special.
You don’t need to prove anything to them.
You don’t need to prove anything to the crowd.
You just carry that watch’s rhythm in your head.
*Tick-tock.
In-in, out-out.*”
Urara stared down at the silver watch in her hands.
The cool metal was quickly absorbing the heat from her palms.
The rhythmic *tick-tick-tick* seemed to echo the beat of her own heart—not the frantic, panic-driven racing of a girl trying to escape failure, but a steady, unbreakable cadence.
A slow, brilliant warmth bloomed across her face, flushing her cheeks pink as her ears snapped back upright with a sharp *flick*.
“Trainer…” she murmured, holding the watch against her chest as if it were the most precious treasure in the world.
“Can I hold it during the race?”
“No, you’ll drop it in the dirt and I’ll have to spend twenty minutes looking for it,” Kazuma grunted, taking the watch back and dropping it into his pocket.
“I’ll hold it at the rail.
Every time you pass the grandstand, you look at me.
I’ll be standing there in this hideous green jacket, holding the watch.
That’s your signal that everything is fine.”
Urara’s tail gave a sudden, powerful *THWACK* against the wooden bench, kicking up a small cloud of dust.
“Okay!
I’ll look for the green jacket!”
“Good,” Kazuma said, turning around and stretching his arms over his head.
“Now, since we wasted fifteen minutes discussing your existential dread, we owe the schedule two sets of core stability drills.
Get off the bench.”
“Ehhhh?!
But my feet are so comfy!” Urara wailed, though there was zero sincerity in her complaint.
She slid off the bench instantly, landing on her feet with a bright, energetic pop.
For the next hour, as the shadows of the ginkgo trees lengthened across the dirt loop, the quiet corner of Tracen Academy was filled with the rhythmic sounds of their training: the heavy *thud* of a medicine ball, Kazuma’s constant, dry complaints about his aching back, and Urara’s high-pitched, infectious laughter ringing out against the warm afternoon air.
They weren’t building a champion.
They weren’t preparing a legend for the history books.
They were just two ordinary, stubbornly unambitious souls preparing to take on a tiny, dusty race in a quiet corner of the country—and as the sun set over the horizon, casting a long, golden light over the track, neither of them would have traded places with anyone else in the world.
