[Here is the extra chapter since Max Verstappen Won]

"…No thank you, Oguri Cap–senpai."
Facing Oguri Cap's enthusiastic invitation, Narita Brian looked a bit awkward beneath her cold expression."I can't eat that much… but thank you for your kindness, senpai."
"Can't eat that much?"
Oguri Cap sounded disappointed. "That's really a shame… soba is delicious, and it's nutritious."
"If you eat too many kinds of noodles, you may get fat, but soba won't. It's one of the few noodles you can eat a lot of without worry."
"Sister Kyoko said there's something-something acid in this kind of noodle, and something-something fiber. It fills you up and it's easy to digest."
"Though…"
She rubbed her belly and smiled. "I don't think soba tastes sour at all. And digestion… well, my digestion is pretty good anyway."
The Eisei Team had always placed great importance on dietary health. Their menu had undergone countless rounds of adjustment, with different diet types tailored to different horse girls.
Most trainers believed a horse girl's daily diet should carefully balance carbs, fat, and protein to avoid weight gain.
During special training, meals needed to supply enough energy to prevent exhaustion from intense exercise.
Japan as a whole valued development in this area, with specialized legislation, clinical nutrition departments, and social dietary guidance—some of which was even mandatory.
For example, some school meal systems had compulsory standards.
Tracen Academy also had related policies, mostly based on trainers' experiences.
But in the eyes of Kitahara and the Eisei team, those methods were far too basic. Instead, they formulated new "levels" of nutritional theory, based on Kitahara's ideas and Miyamura Kyoko's professional expertise.
In another world line, nutrition science had already developed into five levels:
Material Level — Historical categories of food based on culture and experience.
Nutrient Element Level — Analyzing nutrients in small structures and identifying their functions.
Chemical Structure Level — Further breaking down nutrient composition and mechanisms.
Molecules / Atoms Level — Microscopic structural research.
Gene Structure Level — Analyzing the relationship between food microstructure and genes, determining how nutrients affect humans and horse girls at different physiological stages.
Before the Japanese Derby, Eisei's research and application were still in the first few levels.
Afterward—thanks to cooperation with many horse girls, especially the Golden family—Eisei had begun constructing genetic profiles related to the gray-hair bloodline.
With these genetic profiles as a foundation, their diet planning differed substantially from those of ordinary trainers.
Anyone who observed Miyamura Kyoko's daily work designing and refining Oguri Cap's and others' meal plans would realize the terrifying degree of precision involved.
Strictly speaking, others were conducting similar research.Several Japanese universities had equine-girl–related programs.Komiyama Katsumi, Yuzuhara Tarō, and Miyamura Kyoko all graduated from such schools.
There were academic studies and practical results—But compared to Miyamura Kyoko, they still fell short.
She worked daily with the strongest active horse girls and constantly updated her data, allowing immediate improvements.
Others simply lacked this level of real-time support.
Of course, Kyoko's achievements weren't purely personal effort. She stayed with Eisei most of the time but also visited universities to exchange findings.Sometimes, when she saw something practical, she would collaborate—Eisei gained application results, the researchers gained proof, and Kyoko increased her paper output.
Through long-term specialized research and practice, although Kyoko was the one who understood nutrition best, the rest of Eisei had also absorbed some knowledge.
Oguri Cap's explanation earlier came from Kyoko's constant reminders.
But Narita Brian—who had barely interacted with Eisei—didn't understand these things, nor Oguri Cap's conversational habits. She was understandably confused.
"W-What acid? What fiber?" she asked.
"Lysine and dietary fiber," Kitahara replied with a smile. "Lysine is a nutrient, and dietary fiber helps with satiety and digestion—basically what Oguri said."
"Oguri remembering these things she's not interested in is rare… looks like Kyoko really does nag you all a lot."
"It's not nagging! Kyoko cares about us!" Oguri Cap protested seriously.
"Okay, okay, I used the wrong word. I apologize to Kyoko."
With a helpless smile, Kitahara continued, "Anyway, let's not stand outside talking. If we're having dinner, let's go inside."
"I brought Brian along today because I want to invite her to join our training camp."
"She already agreed, so I'd like to explain some arrangements."
Initially, Kitahara simply wanted Brian to greet Oguri Cap and Oguri Roman. He planned to explain training arrangements tomorrow.
Maybe after Yabuhara's invitation, more horse girls would join tomorrow—introducing everything together then would be fine.
But earlier, Kitahara noticed something:
Horse girls who hadn't stayed with the Eisei team lacked understanding in many areas.
Nutrition was only one detail. Most horse girls and trainers didn't know nutritional minutiae, but in Eisei, everyone knew something.
And when it came to training, the differences inside and outside the team were far bigger.
If Brian was confused about one area, she'd definitely be confused about others.Other horse girls would be the same.
To train well together, they needed a way to help newcomers adapt quickly.
Kitahara didn't intend to explain everything directly, but to gradually introduce training arrangements—naturally exposing team methods and details.
If Brian understood quickly, then the same approach would work for Tokai Teio and Mejiro McQueen as well.
Oguri Cap, Roman, and Brian didn't think this deeply. Since it was dinner time, they readily agreed.
The noodle shop owner greeted them enthusiastically—obviously Oguri Cap's big-eater challenge had brought him many customers.
Excited, he approached, patting his chest gratefully:
"Thank you for visiting my humble shop!"
"And thank you, Oguri Cap, for joining our challenge! I'm so grateful—so many customers have come because of you!"
"The others haven't eaten yet, right? All of you—tonight is on the house! Eat as much as you want!"
"And Oguri Cap, if you're not full yet, you can also eat as much as you like! No problem at all!"
Kitahara wasn't surprised the owner recognized Oguri Cap.
She had 16 wins in 16 races, holding two undefeated crowns—she was already extremely famous in Japan.
Most people recognized her immediately.Even outside the shop earlier, many passersby noticed her. Her ability to attract customers wasn't just because she ate well—her idol effect was huge.
But hearing the owner's last sentence, Kitahara paused.
"…We'll pay normally. Please, absolutely don't insist."
The shop owner looked like he wanted to express his gratitude, so Kitahara quickly continued with an awkward smile:
"How should I put this… Oguri Cap seems to like this place. She might visit again."
"And if your shop goes bankrupt right after opening… that would be a shame."
"In any case, we'll pay normally. Please just give us a quieter seat. Thank you."
His tone at the end carried an unmistakable authority.
The owner couldn't refuse, and led them to a private room upstairs.
Oguri Roman had already ordered earlier, so the dishes came quickly.
And, as usual for Eisei, everyone else finished eating while Oguri Cap continued.She had already eaten multiple bowls during the big-eater challenge, and now she ordered several more giant bowls.
The owner finally understood why Kitahara insisted on paying—but he still insisted on letting them eat for free.
"It's fine! Our shop can handle this much! Thank you so much for your understanding, but please allow me to show my appreciation!"
He took out his phone, showing a cute 'Oguri Monster' phone case.
"See? I'm a fan of Oguri Cap myself! Please, let me do this!"
Since he said that, Kitahara no longer refused.
With Oguri Cap slurping in the background, Kitahara took a moment and prepared to talk with Narita Brian about the training camp.
But unexpectedly, Brian spoke first.
"…This might be presumptuous, but, Chief Kitahara…"
Her bright yellow eyes locked firmly onto him."Could you explain the thing you mentioned with Chairman Rudolf?"
"That… domain."
"I'm very curious about it."
She clearly sensed the domain's unusual significance and went straight to the point.
Kitahara was surprised for a moment, then realized it wasn't unreasonable.
She had great natural talent—horse girls at that level probably sensed the importance of domains instinctively.
Her family wasn't lacking strong horse girls either. Maybe she had encountered the concept before.
She was obsessed with racing; from things Oguri Roman said, she was similar to Oguri Cap—her only real hobby was running.
So if she had encountered theories on domains while looking up information, it wasn't impossible.
Domains weren't a secret in this world—humans and horse girls could both access them under certain conditions.
For humans, they were temporary boosts.For horse girls, they were a special kind of "divine blessing."
"Domains, huh… A bit unexpected, but since you asked, let me explain."
Kitahara briefly described the characteristics and effects of domains, as well as the divine blessing aspect. Then he continued:
"Also—Eisei is currently the only team in the world that can actively develop domains."
"You know the Chouetsu Team, right? They can do a little of it. We exchanged notes before."
"But for certain reasons, they only know how to let a horse girl initially grasp a domain. They haven't mastered how to expand it further. We didn't discuss that part."
"Right now, Eisei can not only let horse girls actively step into domains, but also control the timing of activation."
"In the upcoming training camp, an important goal is learning how to segment domain usage—turning it into a powerful ability you can use multiple times."
Kitahara felt saying this to Brian shouldn't be an issue.
He had learned from Rudolf that not all information should be freely shared.
He wanted every horse girl to have a bright future—but good intentions alone didn't guarantee results.
Knowledge creates advantage.
Advantage creates greater advantage.Only then could they reach dreams faster.
So he now consulted Rudor before sharing anything related to domains.
When Tokai Teio and Mejiro McQueen accidentally learned about domains, Kitahara asked Rudolf—her answer was that since they intended to join Eisei, it was fine.
Brian hadn't discussed joining Eisei, only participating in training camp and helping with theory.
But Rudolf didn't hide anything earlier today, so Kitahara felt he didn't need to either.
He was also curious—he hadn't asked Teio or McQueen their thoughts when they learned about domains.Now he wanted to see Brian's reaction.
Narita Brian fell silent for a long time.
"So only the top horse girl of a generation could enter a domain… I mean, if you hadn't discovered these methods…"
She murmured.
Then suddenly—her yellow eyes flashed with intensity.
"Then, suppose—suppose I lived outside Eisei, and until I debuted, none of your methods were made public…"
"Chief Kitahara—do you think I would ever have had the chance to step into that place?"
"In other words… in your view—"
"Is there any chance I could become the top horse girl of my generation?"
