Umamusume: Jujutsu Kaisen System! [1] & Synopsis

[UMAMUSUME + MAHORAGA’S ADAPTATION WHEEL + BINDING VOWS + OVERPOWERED PROTAGONIST]

El Condor Pasa: “Sorry, Spe-chan, Grass-chan, Sky, Halo-chan. We’re the real humans.”

Kashimo: “Stand proud. You’re strong.”

El Condor Pasa stared at the tears pooled in her palm. “What is this?”

Kashimo: “Hard to say. I’ve never shed any myself.”


“Halo-chan!”

“Spe-chan!”

“Kitty!!”

Tokyo Racecourse.

It was the day of the most anticipated G1 race in the country—the Japanese Derby.

The final three entrants to appear were the top three favorites, three prodigious Umamusume at the pinnacle of their generation. The stands erupted in cheers.

The Derby entrants acknowledged the crowd as they began their pre-race warm-ups—or exchanged the customary barbs with their greatest rivals.

Meanwhile, in an overlooked corner, a blue-haired girl with her hair tied in a bun crouched alone, biting her finger. Near the bottom of the popularity rankings, she kept her eyes fixed on a curvaceous figure out on the course.

Special Week.

As far as Kashimo was concerned, Special Week was unquestionably one of the three strongest runners of the current generation. She was also blessed with enough luck to go her entire racing career without injury.

The luckiest Umamusume wins the Derby.

Today’s Derby was practically Special Week’s home turf. She was indisputably the strongest competitor here. One look at that physique was enough to tell how terrifyingly powerful she was!

As for how Kashimo knew all this?

She was a transmigrator.

In her previous life, she had been locked in a heated online argument over whether Hajime Kashimo could take down all five fighters in Sendai. Then, for no apparent reason, she had transmigrated.

She had expected to end up in a world where everyone fought Sukuna. Somehow, she had instead arrived in the version of the Umamusume world that followed real racing history, becoming an Umamusume named Kashimo—someone who knew the entire plot!

Why had a discussion about Jujutsu Kaisen sent her into Umamusume?

It couldn’t possibly be because both worlds had their own kind of “domain,” could it?

She had not arrived alone, either. A system called the [JUJUTSU SCHOLAR] had come with her.

Kashimo was enthralled by the tremendous strength of an Umamusume, far beyond ordinary human limits, and by the raw power coursing through every part of her body. The exhilaration of racing and battling other Umamusume on the track was utterly addictive.

Her record, however, was less than impressive.

She had lost her Debut to King Halo and only earned her first win on her second attempt. In the graded races that followed, she had fought with everything she had merely to place fifth, sixth, third, fourth, and second, finally earning a place in the Japanese Derby.

But today, victory would undoubtedly be hers.

The benefit of her binding vow had finally kicked in.

What kind of jujutsu sorcerer would never make a binding vow?

“In exchange for being able to use only ninety-five percent of my strength outside G1 races, I will be able to use one hundred and five percent during G1 races.”

Kashimo had made that binding vow before her debut.

It was also the main reason she had managed only one win so far.

She clicked her tongue.

She had been too young and foolish when she first arrived. She had forgotten that she would not even qualify for a G1 race at the beginning.

Her own binding vow had held her back.

But Kashimo was no longer who she had been then. The leap from ninety-five percent to one hundred and five percent made all the difference, giving her enough strength to force her way into contention with the very best.

But it still wasn’t enough!

Kashimo rose to her feet, her gentle features sharpening as her gaze turned fierce.

Her pure-white signature racewear snapped in the wind.

She had now truly grasped the core of cursed energy.

“In exchange for never again being able to enter the Japanese Derby, Kikuka Sho, Yushun Himba (Japanese Oaks), or Shuka Sho, grant me a greater chance of victory in the race ahead.”

The binding vow was established!

Binding vows did not exist in the world of Umamusume.

The fact that Kashimo could form them just as sorcerers did in the world of Jujutsu Kaisen was entirely due to the [JUJUTSU SCHOLAR] SYSTEM.

The system had recreated nearly all of Hajime Kashimo’s abilities almost perfectly. Naturally, that included binding vows—something no jujutsu sorcerer could avoid.

It had also granted her the ability [ADAPTIVE WHEEL], allowing her to adapt more effectively to an Umamusume’s body.

She opened the system.

Kashimo suspected that not only had she become an Umamusume, but the system had been Umamusume-ified too—just not all the way.

She looked up at the wheel above her head. It resembled Mahoraga’s adaptation wheel and could be seen only by her. Not even a mirror or camera could capture it.

It allowed her to adapt during races. Every time the wheel turned, she became a little stronger.

Perhaps the system had an adaptation wheel of its own. It had adapted after arriving in this world but failed to finish the process.

The point shop was a perfect example.

Create Cursed Corpse?

What use was that to an Umamusume? Was she supposed to make one, have it ambush her opponents before the race, declare that victory had been decided off the track, and pull a Tonya Harding?

And what was the Mysterious Farmhouse Retreat supposed to do? After the race, would all her opponents start believing she was their long-lost little sister—or even run off to till the fields?

Forget it.

It didn’t matter.

Kashimo closed the system. All she needed to know was that it could make her stronger and that she currently had a fifteen-percent boost.

“FANS OF THE TWINKLE SERIES!”

“AT LAST, THE MOMENT HAS ARRIVED!”

“TODAY’S MAIN EVENT IS THE GRAND FESTIVAL OF UMAMUSUME RACING—THE TOKYO YUSHUN!”

“THE! JAPANESE! DERBY!”

“WITH MORE THAN ONE HUNDRED AND FIFTY THOUSAND SPECTATORS WATCHING, EVERY COMPETITOR IS NOW ENTERING THE STARTING GATES!”

“SEVERAL PAIRS OF OLD RIVALS HAVE GATHERED ON THIS COURSE!”

“OF THE EIGHTEEN UMAMUSUME IN THE FIELD, WHICH ONE WILL ULTIMATELY STAND BENEATH THE SPOTLIGHT OF VICTORY?”

“WILL IT BE KING HALO, CHARGING TOWARD THE VERY TOP?”

“WILL IT BE THE MIRACULOUS UMAMUSUME, SPECIAL WEEK?”

“OR WILL IT BE THE MASTER TACTICIAN WHO WON THE SATSUKI SHO AND NOW SEEKS HER SECOND CROWN—SEIUN SKY?”

“THE RACE IS ABOUT TO BEGIN! KEEP YOUR EYES ON THE COURSE!”

The commentator’s voice echoed in Kashimo’s ears.

A staff member guided her into gate thirteen. Beside her, Seiun Sky stood with her eyes closed as the staff eased her into gate twelve.

“Fawn.”

Kashimo glanced sideways.

Seiun Sky’s instinctive dislike of cramped spaces such as starting gates was no secret. Plenty of Umamusume were the same way.

Was she really going to start the pre-race trash talk even under these circumstances?

No. Maybe she was talking to distract herself from the confined space and improve her start.

“I got your challenge letter.”

Challenge letter?

What challenge letter?

Who even sent challenge letters anymore?

The image of the short upperclassman on her team, another trainee under the same Trainer, flashed through Kashimo’s mind.

She turned her attention back to the gate ahead and the course beyond it.

She refused to think about the letter.

So this was Seiun Sky. Was she trying to distract Kashimo before the race with a single sentence, hoping to make her botch the start?

A master tactician, skilled at schemes.

The race had begun before the gates had even opened.

Kashimo’s lips curled upward, her gaze turning razor-sharp.

“Honestly…”

“Don’t get my hopes up too much, okay?”
