The premise of breaking up in Tokyo

Before Yuma Kanzaki came out, Murayama was still talking incessantly to Katsuhiko, his eyes filled with admiration.

Their department head Kanzaki's master was a disciple of Mas Oyama, the legendary "King of Karate" and the founder of Kyokushin Karate, and one of his outstanding students.

It can be considered officially authorized, belonging to a branch of a prestigious and righteous sect...

Yuzuru Kanzaki is currently a third-year student in the Faculty of Letters. She is one of the few athletes who earned her first black belt during her second year of university, and she has reached the quarterfinals and even the semifinals in the All-Japan Lightweight Championships.

Now, she's become a star in the Kanto female student karate circle, nicknamed "Inamon's Akishimo"...

While being a "top student," Katsuhiko was just going through the motions with Murayama, picking out useful information and filtering it in his mind.

In Katsuhiko's eyes, Murayama now seems like both a die-hard fan of Yuma Kanzaki and a salesman, introducing his lineage and making a triple spin... He has absolutely nothing to do with Masatoshi Oyama anymore.

Of course, it can also be useful, after all, he has achieved a black belt and participated in competitions.

Although there may be a significant difference in the male-female confrontation, the basic skills and combat routines are common and can be learned, and it's free to learn them.

Katsuhiko discovered that after being given a "Focus" buff, he became a martial arts genius that was "once in a million years".

There were also people practicing around. Watching their precise and methodical fighting routines, Katsuhiko not only had a photographic memory, but he could also apply what he learned to other situations and practice variations in his mind.

Just after Katsuhiko drank three cups of purified water that Murayama had given him in a disposable paper cup, a female student wearing a white training uniform with a black cloth belt around her waist walked out of the training room barefoot.

With black hair tied in a high ponytail and slender, slightly upturned eyebrows, she looked quite dashing.

She was nearly 1.7 meters tall. The first thing Sheng Yan noticed when he turned his head to look at her was that her legs were about two or three centimeters longer than the normal golden ratio... right?

She must be good at kicking... right?

Although the skin on her hands was still fair, the joints of her ten fingers were noticeably larger, as if she were also good at punching... right?

Yuma Kanzaki was probably not a talkative person. She walked over with a cold face, glanced at Chinatsu who had wide, curious eyes, gave Katsuhiko a brief self-introduction, bowed, and then began the rehearsal.

Katsuhiko immediately saw through her act: hitting the equipment, hitting the air, and making exaggerated "humming and hawing" sounds...

Of course, if you watch it with the mindset of "appreciating a performance," it is a beautiful sight. Her high ponytail, tied on top of her head, dances like a ribbon. If she changed her clothes... Mai Shiranui? No, Mai Shiranui doesn't have such a flat chest.

Mai Shiranui can shout "Gar chives!", but she can only say "Hmph hahaha".

Chinatsu clapped her hands and jumped around, grabbing Katsuhiko's trouser leg with one hand and pointing at Yuma Kanzaki with the other, shouting with her head up, "I want to learn! I want to learn!"

A hint of joy flashed in Kanzaki Yuma's eyes, but she quickly concealed it and launched into another round of "humphs and laughter," making a fierce and powerful fight.

Sheng Yan lowered his head and said, "If you call me 'Dad,' I'll let you learn."

Chinatsu covered her mouth with her outstretched hand, then turned her head to one side, her eyes full of laughter, and said, "I want to learn~".

Kanzaki Yuma abruptly ended the rehearsal, her fair face still tense, standing straight as she faced Katsuhiko and Chinatsu.

Katsuhiko asked her, "Have you finished practicing?"

Shinji Yuzuru, without looking to the side, said, "I'm done practicing."

"Are you putting on an act for her? Or for me? I want real combat, not this kind of cool, pose-taking stupid act."

"You're not under my jurisdiction. If you want to learn, go pay the fees!" Kanzaki Yuma said, half-squatting in front of Chinatsu. The ends of her long ponytail touched the floor. She still had a tense expression, blinked twice, and said, "Chinatsu-chan, do you want to learn? I'll teach you."

Chinatsu's eyes were full of excitement and anticipation, but she didn't respond to her. Instead, she looked up at Katsuhiko with a pitiful expression.

"Go, go, go!" Katsuhiko waved his hand impatiently.

After Kagami Yuma led Chinatsu into the training room, they entered.

Still standing nearby, Murayama scratched his head and chuckled awkwardly, as if he had expected this outcome... He said, "Mr. Takenaka, would you like to see more? I am Shirota, and I can demonstrate for you."

"Wait until you've turned green with envy before you ask me to act again!"

The entire training room was a mix of red, blue, green, and white, except for Shinki Yuzuru, who was black. We had to see what she was really capable of.

Sheng Yan said, taking two quick steps and following him into the training room.

There were also seven children wearing white belts in the practice room, all around four or five years old, four boys and three girls.

With the addition of Chika, who just joined, there are now four pairs.

Lacking children? Taking advantage of adults? Sheng Yan paused, then paused, "You never intended for me to learn?"

Yuma Kanzaki turned around, her face still tense, and asked, "Are you going to join the kids' group too?"

"I question your abilities," Katsuhiko said, glancing at the black belt around her waist. "Did you have someone buy that black belt for you, or did you sew it yourself secretly?"

The surroundings were completely silent, and the children all looked up with their mouths agape...

Kanzaki Yuma's eye twitched, her expressionless face instantly darkening. She released Chinatsu's small hand and took a sudden step closer to Katsuhiko.

Normally, anyone would instinctively back away if someone suddenly appeared in front of them like that, but Sheng Yan was "abnormal" and took a small step forward as well.

The two bumped chests together.

Yuma Kazaki's gloomy face suddenly froze, her eyes filled with disbelief.

But she didn't back down or panic. Instead, she gritted her teeth, pushed Sheng Yan's chest with her shoulder, and then walked to the door, grabbed the sliding door of the practice room, and slammed it shut.

She then slowly turned around, lowered her head to face the floor, and blindly pointed to the equipment on the wall, saying to Katsuhiko, "Go put on your protective gear."

It seems a major decision has been made...

Having achieved his goal, Sheng Yan was too lazy to waste any more words with her. He decisively took the protective gear and put it on.

My photographic memory just now gave me at least a level four or five green belt theoretical framework. Even if she's a black belt, a 21-year-old student with skinny arms and legs... one bear hug from me could crush all her bones...

The children got excited and stopped making noise. Instead, they gathered in a corner, and Chika was pulled together by a little girl.

Just as Katsuhiko finished putting on his boxing gloves and booties, Yuma Kanzaki was already fully dressed and stretching her muscles by punching and kicking in the open space in the center. She also tied her ponytail tightly and coiled it on top of her head to create a bun hairstyle.

Katsuhiko, with the headgear straps still on, asked, "Aren't you wearing a face shield?"

Yuma Kanzaki kicked out a high kick towards Katsuhiko, almost at a 180° angle, her foot poised in mid-air, and said, "I don't need to hit you."

"Alright!"

Katsuhiko didn't intend to launch any attack; he mainly wanted to observe her "Kyokushin Karate" fighting style and techniques, and learn some tricks...

After the two stood facing each other, Yuma Kanzaki bowed to Katsuhiko first, and Katsuhiko, after glancing at the children around him, also bowed.

With a shout of "Start!" from Kanzaki Yuma, she kicked Teruhiko's left cheek with a high kick.

Her attack movements should have been fast, but in his "focused" state, Katsuhiko's brain was extremely active, and his reaction speed was also increasing in tandem. He immediately saw through her method of exertion, and from this, he could easily deduce her attack posture and target.

Countless ways to flip her over flashed through Sheng Yan's mind: grab her legs and give her a windmill kick?

Forget it... Katsuhiko quickly raised his arm to block, intending to kick her down, but then he thought that she was "fighting for dignity" now. If he really kicked her, she probably wouldn't be able to take it, and might not be able to stay here with her face. So he decided to forget it, since Chika really seemed very interested.

As Katsuhiko's mind raced, a label suddenly appeared in his field of vision: [Assets: -320000000 yen].

"Huh?" Katsuhiko was stunned. Although he instantly read out 320 million yen, the minus sign made him a little suspicious. A 21-year-old female student...

"Bang!"

Katsuhiko was too lazy to hide anymore.

The kick did have some force, and my arm went slightly numb. However, thanks to his innate abilities, Katsuhiko easily withstood it.

Kazaki Yuma panicked, took three steps back, and assumed a defensive stance with her eyes wide open.

From her incredulous gaze, Sheng Yan deduced one thing: "You're here to cause trouble, aren't you?"

Katsuhiko didn't bother thinking about her debt problem anymore.

With his thoughts returning to the right track, Katsuhiko realized that with the super-fast nerve reaction speed provided by the [Focus Potion], coupled with his own strong hands-on skills, physique, and constitution, he was completely dominant in fights.

After all, they are quick to react and agile.

I just memorized all the attack methods of the trainees around me, and even applied what I learned to other situations, drawing on the routines of martial arts movie actors to create my own moves. In other words, I have already mastered them.

I'm going to fight in the street, not to compete, so I don't need to learn any rules or taboos.

They did whatever was convenient: grabbing someone's crotch, hitting the back of their head, biting their ears, scratching their skin, grabbing their face, gouging their eyes, pulling their nose... whatever was convenient.

With the [Focus Potion], I can figure out how to fight on my own. After all, the human body is naturally designed for fighting. Now I'll go back to the convenience store and maybe find some books on acupuncture points in the bookstore while I'm at it. I'll memorize them after just one glance...

"That's enough. I acknowledge your skill," Katsuhiko said, removing all his protective gear. He turned to Chika and asked, "Chika-chan, do you really want to learn here?"

Qianxia held a little girl's hand and nodded like a chick pecking at rice.

Looks like I've found new friends...

"Alright!" Katsuhiko casually shoved the protective gear into the still-dazed Yuma Kanzaki's hands, then went out and said, "I'm going to pay Chinatsu-chan's tuition."

Yuma Kanzaki had her back to Katsuhiko and didn't respond.

The little girl next to Chika leaned close to Chika's ear and asked, "Is that your dad?"

Chika glanced furtively at Katsuhiko's retreating figure, then nodded with pursed lips, "Mmm..."

……

As soon as Katsuhiko opened the door, Murayama appeared, holding a registration form with a fawning smile on his face.

"Thank you for your trust, Mr. Takenaka, we..."

Before he could finish speaking, Katsuhiko took out 200,000 yen from his pocket, counted out 5000 yen plus 2000 yen for food expenses, stuffed it into Murayama's hand, and then took the registration form.

Basic information registration: home address, home phone number, parents' names, student's name...

After finishing the registration form, Katsuhiko told Chinatsu again, "Come pick her up tonight." Just as he was about to leave, he remembered the medical book issue, turned around and looked at Yuma Shinzaki, who was staring at him with a tense face, and asked, "Department Head Yuma, do you have a library card? I'd like to go to your school's library."

With a stern face, Yuma Kamisaki pointed to the wooden storage shelf by the door and said, "It's tucked inside that book."

On the shelf sat a novel called "Hearing the Waves," with an illustration of a man and woman holding hands on the cover. The book also included a synopsis, telling a story of innocence and regret that took place on campus... It was a poignant romance novel.

Sheng Yan didn't like any heart-wrenching love stories, so he took out his library card, said thank you, and left.

Although it was the Golden Week holiday, there were students working part-time at the library, so Sheng Yan didn't spend much time there. He borrowed two books about acupoints in traditional Chinese medicine and then left the school.

It's less than ten minutes from my apartment in Okubo, and less than ten minutes from the convenience store. It's a triangular route. If you add Mikoto's home address, it becomes a roughly rectangular route.

Katsuhiko returned to the convenience store at noon. The pile of garbage in front of the store had been cleaned up, but the red paint on the white iron roller door was still very conspicuous.

The A4 paper challenge that had been posted on the door earlier, which read "Respectfully submitted by Group 21," also included the words "If you do not find me when you visit, please come back after dark," so Katsuhiko was too lazy to go looking for it himself.

Since waiting was boring, Katsuhiko pulled up the roller shutter and opened the shop for business.

I put a plate of pasta into the microwave and checked the inventory list to plan a clearance sale of goods that had been sitting unsold for more than a month.

The landline at the cashier rang, displaying Mikoto's landline number.

Mikoto called to ask if Katsuhiko wanted to come home for dinner, as there were leftovers from last night that she and Sayuri couldn't finish.

Katsuhiko was eating pasta, so he declined, and casually mentioned that he was planning an inventory clearance event.

Mikoto also said that she would come over to help after she and Sayuri finished their meal.

Katsuhiko decided not to let the two of them come, considering that they would have to wait for the yakuza to come that night and there was no guarantee that a conflict would not occur.

Instead, Mikoto was given a task: after dinner, she was to drive the Mazda, take Sayuri to the nearby flea market, buy used game cartridges, and go straight home that night…

Although Mikoto is over ten million yen in debt, she still has over three million yen in cash, mainly for payments to suppliers, loan interest, and Chinatsu's daily expenses...

Mikoto was quite self-aware; she only reminded Katsuhiko to "be careful" and didn't say anything more before hanging up the phone.

After hanging up the phone, Katsuhiko belatedly realized that Mikoto hadn't asked about Chinatsu.

It doesn't matter, since it's not far away. If she doesn't have time to pick him up, Yuma will naturally call.

We'll wait until we've planned a big promotional event.

Katsuhiko originally intended to focus on medical books for the rest of the time, but in just one hour, he had memorized two medical books, each about an inch thick, one on massage and the other on acupuncture...

Unfortunately, even if you know it by heart, you can't use it for clinical diagnosis and treatment. After all, traditional Chinese medicine treats patients differently depending on their symptoms, with each doctor having their own treatment method.

Of course, it's more than enough for ambushes and sneak attacks.

As the sun began to set, orange sunlight streamed through the window, while the roar of motorcycles echoed from outside.
