The 200 km/h light train is speeding on the tracks, the scenery outside the double window is blurred, and the bright sunlight cuts through the streamlined slender body, reflecting a dazzling light under the long summer sky.

An old woman in a kimono sits upright in a stable carriage, her meticulous bun and closed lips speak to the strict character of her master, and even appear to be a little stern. This kind of soul-like temperament can't help but make the surrounding passengers lower their chatting voices under this wonderful aura. Beside her sat a red-haired girl in uniform, gently turning the pages of a book on her lap in silence, reading a copy of Kyotaro Nishimura's The Strange Case of the Sakura Train, with the occasional flash of golden-green streamers in her slightly drooping eyelids.

――These two people are Nao, Saotome, who lives in Kakudocho, Tokyo, and her grandmother.

Today is Friday, and the first round of the karate tournament ended two days ago. The crowd of the clubs who got tickets to the semifinals of the Tokyo Metropolitan Government was full of excitement, and as soon as the class ended, the club's dojo was filled with shouts, and the members of the women's and men's divisions were preparing for the upcoming important matches. However, Nao, who was the main force, did not participate in club activities after school, but hurried home after saying goodbye to Natsuki and embarked on the Shinkansen to Kanagawa with her long-awaited grandmother......

Her grandmother, Sakurako, Saotome, changed Nao's trip to Kanagawa alone: the visit, which was originally scheduled for Saturday, was brought forward to today, and the members of the group changed from one person to two. The grandmother's sudden decision to accompany not only did not tell Jinping, but even Aiko was kept in the dark, plus the solemn advice before leaving...... This unusual behavior made Nao smell a subtle nervousness.

The red-haired girl saw her grandmother's rock-like expression in her peripheral vision, and then shifted her attention to her slightly trembling fists, a slight glow of interest shining under her eyelashes.

"Are you prepared?" Sakurako seemed to notice Nao's gaze, coughed dryly, and opened her mouth.

"What do you mean?" the girl beside her curled the corners of her mouth, her eyes never seemed to leave the book on her lap for a moment, "'You can't be rude to that gentleman,' and 'you have to express your inner intuitive thoughts,' and so on, you explained these words before you left." ”

"Don't interrupt! You know what I'm talking about. The old woman frowned, "The next training is not as good as before, and only half-baked consciousness is absolutely not enough." ”

"Grandmother, how do you know that gentleman will train me?" she chuckled, "since he is known for his strictness, and he has never seen my watch with his own eyes...... I don't believe that he would allow me to join such a rare training program based on decades of friendship. ”

Sakurako Sakura didn't speak, just snorted softly from the wing of her nose, and for a while, the pressure that could not be ignored permeated the two of them, and the surroundings suddenly became quiet. Nao's fingers, which were about to turn the page, paused, and opened his mouth lightly: "Of course I know." Grandmother, you should know best what my consciousness is. She didn't lift her eyes, but turned a page of the book, "No matter how your old friend trains me, my goal will never change. Whether it's Natsu or my father, I'm not going to give up on either of them. ”

The girl concluded softly, and the almost murmuring voice did not affect the firmness of the words.

"Responsibility and truth, do you want both?" Sakurako suddenly laughed, but there was some bitterness in her laughter, "It seems that you still don't understand......"

Nao's eyelashes trembled, but there was no more conversation, only the crisp sound of flipping books blurred in the air, and Sakurako sighed to herself, and gently closed her eyes.

After a moment of silence, the two of them were once again enveloped by the sound of conversation that gradually sounded around them.

**

A 20-minute walk along the tracks of Kanagawa Station will bring you to a Japanese-style residential area. The two-story wooden structure covers the entire area, and the shade of green covers each building, which can only be seen from the eaves of the trees, and several narrow bluestone paths penetrate like veins, connecting the buildings covered in dark green.

It is adjacent to the foothills, not far from the city traffic and the heat of the air conditioner does not affect it in the slightest, as soon as you enter this residential area, the refreshing cool air will come to your face, seeping into every pore of people, even the most impatient mood can not help but calm down.

"I can't imagine I'll be here again in my lifetime......" Sakurako's grandmother took a deep breath, a hint of gloom flashed in her brown pupils, but then it turned into a complex mixture of firmness and coldness. She looked at the surrounding scenery with a little nostalgia, and her face softened with Chang Yan, but the sharp light in her pupils did not decrease at all, but made people feel more sharp. Nao looked at his grandmother suspiciously, and secretly guessed what kind of person was the person who could make her grandmother show such a contradictory expression.

Clogs and sneakers walked on the stone pavement one after the other, and a courtyard surrounded by pine trees gradually appeared in front of them. Looking at the rigid calligraphy on the wooden door plate, Sakurako's expression was a little dazed, she closed her eyes deeply and exhaled, and when she opened them again, her eyes were already full of determination.

"Nao, knock on the door. ”

--The person who opened the door was a housewife of about forty years old, and when she saw Nao and the others, she was slightly stunned and then bent down.

"It's Mrs. Saotome and her party, the lord has been waiting for a long time. Please come with me. ”

Sakurako nodded, and followed the housekeeper into the courtyard.

Nao followed behind Sakurako without saying a word, listening to the crisp sound of the clogs tapping on the stone path under her grandmother's feet, and looking at the garden decorated with pine trees and strange stones, exuding a solemn atmosphere, a rare layer of tension welled up in her chest, but more than that, it was a shuddering excitement. Even with her calm personality cultivated by years of martial arts training, and the calm and rational nature she has cultivated in the case, it can't make her calm when she is about to face that important person. Her feet moved forward almost mechanically, her eyes glazed with the overexcitement of her cerebral cortex, and she could only feel her heart beating faster and faster in her chest, and her own breathing getting heavier and heavier.

The head of the Fourth Search Division of the Kanagawa Prefectural Metropolitan Police Department, an instructor at the Kanagawa Prefectural Police Academy, and a chief kendo instructor at the Kanagawa Police Station Dojo - this is the position of the gentleman she was about to meet after Nao asked Matsuda Jinpei to find out after getting the contact information given to her by her grandmother. For her, perhaps the most important thing was the position of "police academy instructor" that he could help Nao train, but after seeing her grandmother's nostalgic and complicated look, and learning that the cause of her father's death was inseparable from the whereabouts of a foreign "boss", her attention shifted to another position of the inspector, the head of the fourth search section of the Kanagawa Prefectural Metropolitan Police Department.

Ordinary people, and even ordinary police officers of the Metropolitan Police Department, may not know about it, but Matsuda Jinpei, who is the captain of the First Security Division of the Tokyo Metropolitan Police Department, privately told her that the Fourth Search Division of the Kanagawa Police Station is a different and unknown department. Unlike other prefectures, which are responsible for the search of criminal information, it is responsible for more complex and secretive work, and is a general term for a certain department, just like the "office" of the FBI and the "club" of the CIA.

-- The International Organization Crime Countermeasures Headquarters, established at the Kanagawa Prefectural Metropolitan Police Department, commonly known as the "Four Search Divisions."

Are grandmothers and this inspector really just "old friends who haven't seen each other for many years"? Why did my grandmother find an old friend who was far away in Kanagawa to give her special training, and was it only because he was an "instructor at the police academy"? Does this special "four lessons in search" have anything to do with the death of her grandmother or father?

Many questions surrounded her, as if layers of fog were enveloping her.

She seemed to hold two threads in her hands, one shining and clearly visible for her special training, the duty to protect, and the other looming, perhaps leading to the truth, hidden in the fog. The two threads seem to be entangled, and they seem to be completely separated. If she wants to reach the other side of the fog, can she only go straight along this clear path, and if she chooses the unclear truth, will she get lost in the fog?

No matter how she guesses and which path she will choose in the end, this trip to Kanagawa is undoubtedly a www.biquge.info to solve a question.

Regardless of whether her father is a CIA or not, whether his death has anything to do with the unknown foreigner or the childhood sweetheart of the US military base, only this "International Organization Crime Division" can approach them, and she can only approach this secret "Search Four Lessons" from this meeting.

Nao closed her eyes, forcing herself to calm down, suppressing the excitement and tension in her chest, and when she opened her eyes again, a touch of golden green was already firm and fierce.

Yes, the first thing she has to do is get close.

Tong Guò met close to the chief inspector, close to the special training, close to the Metropolitan Police Department, close to the search section...... Until, close to the truth.

As they marched, they came to a Japanese-style room that was closed on three sides and faced the courtyard on one side. A tall and stern old man stood on the corridor next to the courtyard, staring at them with his hands in his hands. His spine was straight, his dark ochre-colored kimono made him stand tall, his eyes had already shown signs of erosion by time, and the furrows between his eyebrows were like knife cuts.

Nao wanted to look down like a qualified junior, but when he saw his eagle-sharp eyes, he involuntarily straightened his waist and met his gaze. Unexpectedly, the old man just swept his gaze away, and it seemed that he didn't take Nao's impolite direct gaze to heart at all, but instead opened a small smile at the corner of his lips and looked at Saotome Sakurako under the porch.

"Sure enough, I've become an old woman!" the old man's voice was clear and smiling.

"Hmph, haven't you become an old man. Sakurako snorted unrelentingly, but her voice trembled slightly.

"Heh, yes, after all, I haven't seen each other for more than thirty years. ”

The old man chuckled and beckoned Sakurako into the house, never looking at Nao again. Looking at the two old men who had entered the Japanese room, Nao, who was still standing under the porch, had a flash in his eyes, and lowered his head and hooked the corners of his mouth. Not to mention that the old man, who is the owner of the courtyard, did not even pay attention to her grandmother, but left her alone, which is illogical.

What a temptation to ...... When is she a vulnerable little girl?

Nao gathered the light in his eyes, lowered his head and took off his shoes, and respectfully knelt down on the corridor about half a meter away from the door.

There is only one unclosed paper door between the Japanese-style room and the garden, and Nao's position is right behind Sakurako's left, so that Sakurako's figure can not only block the old man's view, but also clearly see the person sitting opposite and the whole house, so it is a good place to gather information, hide yourself, and show respect. Looking at the praise that flashed in the eyes of the old man opposite, she knew that her Warring States history was not in vain. She sat with her eyes level, quietly listening to the conversation between the two old men.

"After all these years, I didn't think you would ever return to the island. The old man in the main seat narrowed his eyes slightly, as if looking at Sakurako opposite, "The last time I went to Tokyo for a meeting, Matsumoto asked about you." If you hadn't left, you'd be an indispensable figure in the Tokyo Metropolitan Police Department by now...... Why do you suddenly want to come back?"

"It's a faux pas, and I was already an indispensable figure at the time. Sakurako laughed, "I've been in Okinawa for a long time, and I'm about to forget the scenery of my hometown, so why don't I come back and see it when I can move." I didn't expect that in addition to you, that kid from Matsumoto also remembered me, an old woman. ”

"Haha! You're still the same, kid boy all day long, don't forget it's been more than thirty years, and Matsumoto is now in his fifties!" the old man laughed, and he couldn't see Yan Sù's shadow just now, "So, how long are you going to stay when you come back this time?"

"If there is no accident, I will stay here with my son. Sakurako took a sip of the tea brought by the housekeeper and sighed with satisfaction, "This time I came back not only to retire in Tokyo, but also to ask Aiko to help me watch over my two granddaughters." I'm old after all, who knows when I'm going to ......"

"Don't think about those things all the time," the old man frowned, "you've been gone for so many years, and this place is already safe." ”

Disappearing?safe?Nao's heart sank.

"Yes. After all, my son has been gone for more than ten years, so I can't let his child live in Okinawa all the time. Sakurako put down the teacup and sighed, tilted her head to the back, and raised a smile of relief when she saw Nao sitting behind her with her head down, "This is Haoping's eldest daughter, named Nao." ”

Feeling the gaze floating above his head, Nao immediately sat upright, folded his fingertips in front of his knees, and □ towards the old man's position.

"The first time we met, I was Saotome Nao, and I had heard the name of the Sanada police officer, so please give me a lot of advice. ”

Looking at Nao's standard kneeling ceremony, Sanada nodded with emotion: "It's really good, few young people pay so much attention to etiquette now, and it seems that they also have a martial arts foundation, right?"

"Yes, I studied karate for a few years. ”

"Karate?" The old man was stunned for a moment, met Sakurako's slightly proud expression, and suddenly laughed, "Okinawa, Saotome Nao, I see! The face of the Yokomi in a lesson a while ago has darkened for several days, and it turns out that your granddaughter did it." It's really worthy of what you taught, hahaha!"

"If you were a police officer, this girl's level would be far behind. Sakurako narrowed her eyes and looked at the chief inspector Sanada who was seated, "If you don't dislike it, take her to you to hone and hone, so that my old woman can rest at home for a while." ”

"Is her ambition to be a police officer in the future? It's good to let her go there and learn first. The old man touched his chin, "If you have good grades, you can enter the Metropolitan Police Department's search squad when you are in high school." ”

Hearing the old man's words, Nao was stunned. She looked at her grandmother, who nodded at her slightly, and raised her face to Sanada and asked, "You mean...... I don't need to go to high school to get into the Metropolitan Police Department......'s search section?

"How can you not go to high school? If you want to go to the search class, you must at least graduate from college. Sanada shook his head at her, "I'm not talking about the Metropolitan Police Department's search division, but the search class of the juvenile upbringing division." ”

"Teenager...... Formation class?"

"Yes, the full name is 'Metropolitan Police Department Juvenile Development Division', and under the jurisdiction of the Kanagawa Metropolitan Police Department, it is the department that conducts serious crime investigations, just like the Search Division. The only difference is that it is a unit dedicated to juvenile police officers. He looked at Nao's widening eyes and smiled, "Do you know what the functions of the five divisions of the Metropolitan Police Department's Search Division are?"

Nao nodded, "The first search section is responsible for detecting violent crimes, the second search section is responsible for economic crimes, the third search section is responsible for theft, and the fourth search section is an international ......"

The sound stopped abruptly.

Nao, who had been thinking about the "International Organization Crime Section" in her mind, took a deep breath nervously, and quickly glanced at the expressionless Sanada Hongichi and Saotome Sakurako, "The fourth section is responsible for the search of criminal materials and the identification of crime clues at the scene, also known as the co-assistance class, and the fifth department is the forensic class." ”

“...... That's right. Sanada and Sakurako looked at each other and continued casually, "The Juvenile Formation Class is the same as the Search Class, but it is based on classes. From the first class of the search to the fourth class of the search, the functions are the same as those of the first lesson of the search division to the identification class. As long as you join the incubation class, you will also participate in handling cases and dispatching police. But if you want to enter the training class, you can only go through the test of the police academy. ”

Nao nodded silently as Chief Sanada almost pierced her gaze, the knuckles of her knots on her lap white.

Sakurako Sakurako Sakura sighed faintly and shook her head at Sanada.

"If you want to enter the incubation class, you need to start learning in the shortest possible time. Sanada Koichi looked at Nao, who seemed to be trembling, and his gaze softened a little, "You can try to come to the class for a week first, and of course the martial arts training, if you can withstand this kind of intensity......"

Hearing this, Nao raised her head suddenly, and her golden-green eyes burst out with dazzling brilliance. She put her hands in front of her knees and bowed solemnly to Inspector Sanada.

"-Please let me participate in training!!"

Facing the burning eyes of Nao, Sakurako's grandmother and Sanada both smiled in the corners of their eyes.

Nao didn't participate in the conversation that followed. The Sanada police chief said that he wanted to catch up with Sakurako and let his grandson, who had returned from school, accompany Nao to visit the garden, and Nao readily agreed. As the stern-faced young man and Nao walked down the corridor, a conversation came from inside the room that was noticeably muffled.

"What are those things, you sued her?"

"No, Nao should have only found out about Kohei's death, and the rest ......"

In the shadow of the slanting sun, Nao, who was a little depressed just now because of "leaking his mouth", showed a shallow smile.

And the young man standing beside her looked at her smile and shivered.

The author has something to say: after lying in bed for almost two months, even the groove in his head has flattened, so he rewrote the outline and conceived the case.

I hope you will support you in the future, a certain peach bows here!

Let's talk about what follows.

Originally, I wanted to write about karate competitions and the like, but after writing the details of the contest and then writing about the case and plot, I felt that it was too long, so I cut it.

After that, there will be Xiao Nao's training and a new case.,I'm also thinking about whether to let Nioh and Yanagi act with her.,Solve the case and the like.,I hope you will give more opinions~~

PS: The juvenile upbringing class in the article is really available in the Japanese Metropolitan Police Department~

The Sanada boy appeared and sprinkled flowers~

As a result, some people will definitely say, "Sure enough, it's the Sanada family......
