In his past life, Shinji had read several fanfictions about Naruto, many of which focused on reforming the ninja world, often emphasizing infrastructure development, such as building schools. These stories implied that there were no schools in the ninja world except for ninja academies. However, the reality was quite different. There were actually many schools in the ninja world, including private academies in almost every village that taught reading and writing.
Besides basic schools, there were also higher-level institutions, though they were fewer and had more stringent entry requirements. In truth, ninja villages were the most underdeveloped areas in terms of modernization, often hidden in remote mountains or far from civilian populations.
In most countries, ninjas and ordinary people existed as two entirely separate classes, with ninja villages directly interfacing with powerful entities like daimyo. Ninja villages served as the military arm of a nation, providing military strength and facing threats from other ninja villages that endangered national stability.
However, in the later stages of Masashi Kishimoto's storytelling, ninjas, originally shadowy figures performing covert missions, were pushed into the spotlight, depicted as shining paragons, which was quite a deviation from their original role.
Initially, Shinji planned to outsource the task of teaching the three little ones to read and write to a private school, but upon careful consideration, he decided to take on the responsibility himself.
The world of Naruto was one filled with heroism, and private school teachers often imparted such ideologies. To prevent the three from being influenced and brainwashed by these ideas, Shinji chose to teach them personally.
At the beginning, Shinji established a rigorous curriculum for the three, which differed slightly from real-world education and was more intense. They attended classes six days a week, focusing entirely on academic subjects.
Ninjutsu and taijutsu were to be introduced only after they had acquired a solid cultural foundation. For now, they only had a physical education class for some basic exercise.
The subjects included mathematics, history, geography, biology, chemistry, physics, and a history class spiced with politics and literature. Additionally, there were art and physical education classes.
Since Shinji often taught them outdoors, over time, many poor children from the town, who couldn't afford private school, began to join in and listen to the lessons. As time went by, more and more children started attending.
Shinji didn't mind this at all. In fact, he began to understand why Gilgamesh liked children. Untainted by the world and free of ulterior motives, children were indeed endearing.
Spending every day with them, Shinji found himself enjoying the process of imparting knowledge to the little ones. Haku, Karin, and Kimimaro also enjoyed these peaceful, danger-free days, despite their teacher's occasional eccentricities.
Two months passed quickly...
Late at night, in the inn.
Karin was frantically working on the weekend homework assigned by Shinji. School resumed tomorrow, and she had forgotten about the homework until now. If she didn't finish it, she would face more than just a standing punishment.
Thinking she couldn't finish it on her own, Karin decided to seek help from her good "girlfriend" Haku and borrow her homework for reference.
It's worth noting that Karin still hadn't realized Haku wasn't a girl, as Haku wore various dresses every day, just like her.
...
Knock, knock, creak—
Entering the room, little Karin saw Haku changing clothes. Not noticing Haku's slightly flushed face, Karin closed the door and expressed her request.
Seeing Karin's pleading look, Haku, who had started to grasp the concept of gender differences, quietly finished dressing and turned to find her homework.
"Don't worry, I won't copy everything. Teacher Kill won't be able to tell."
As Karin confidently promised not to copy everything, she suddenly sensed something wrong behind her—a presence watching her intently.
Noticing Haku's expression, Karin quickly returned the homework.
"I think I won't copy it..."
"So diligent? You're even checking answers?"
"Teacher Kill!" Karin exclaimed, feigning surprise as she turned to see Shinji.
"Keep up the good work. And remember, sneaking into a boy's room late at night is not something a girl should do, Karin."
Thinking she had fooled Shinji, Karin chuckled awkwardly but then realized something was off.
"Boy?"
"Didn't you know? Haku is a boy."
Stunned for nearly two seconds, Karin turned to Haku, who was exuding a high level of feminine charm.
"Huh?"
"Yes," Haku nodded.
Karin took a deep breath.
"Wait! A boy? A boy! Wait! What are you talking about? Is it April Fool's Day? Are you pranking me? How can Haku be a boy?"
Seeing Karin in a state of complete confusion, Shinji clarified, "No, Haku is indeed a boy."
"Then the usual dressing is..."
"Personal preference," Shinji explained.
Karin: ...
"My personal preference," Shinji added.
Karin: ...
Thinking about how she had treated a boy dressed as a girl like a close friend, Karin felt...
"I can accept that!"
Seeing Karin suddenly excited and holding her shoulders while saying something bizarre, Haku tilted his head in confusion.
"Huh?"
"I said I can accept it! And... it's great! Haku, keep being yourself! I can totally accept it! In fact, I think it's great! Awesome!"
Seeing Karin so excited, Shinji nodded silently, impressed by her acceptance.
Truly worthy of being my student!
...
In the early hours, behind the town.
Watching Kimimaro secretly training, Shinji felt a bit helpless. Despite his strict orders against using his bloodline ability, Kimimaro continued to train in secret.
It was as if he was driven, finding secluded spots to train alone whenever he thought no one was watching.
Realizing this couldn't continue, Shinji decided to start teaching them some basics of ninjutsu.
Morning classes would remain academic, but afternoons would be devoted to ninjutsu training.
Silently observing Kimimaro for a while, Shinji left before Kimimaro could exhaust himself.
...
The next day.
"Where are we going, Teacher Kill?"
After two months, Karin had become the most talkative of the three.
Glancing at the three following him with backpacks, Shinji smiled and said, "Of course, to a place with beautiful big sisters."
Karin frowned, "That's lame!"
"Also, starting today, your schedule will change. Mornings will still be academic, but afternoons will be dedicated to ninjutsu training. Six days of classes a week, with one day for travel."
Hearing this, Kimimaro looked surprised and pleased. He had never forgotten the mission Shinji had given him, keeping it firmly in mind.
Though he didn't understand why, if it was a task given by his teacher, he would strive to complete it. While his current strength wasn't enough, he believed that with training, he might achieve it!
"No rest days?!" Karin exclaimed.
"Exactly! No more rest days!"
...
Another day, in the morning.
In the forests of the Land of Grass, near the border of the Land of Rain, Shinji and the three had just finished breakfast.
Summoned once again, Minato looked at the hand on his shoulder, his expression slightly complicated.
"From now on, this person will be your ninjutsu teacher, teaching you the basics of ninjutsu. He will also cook your meals."
"Mr. Anli, I..."
Uncertain of the situation, Minato, who had just been summoned and given this responsibility, awkwardly smiled, but before he could finish, Shinji patted his shoulder.
"I trust you."
Seeing Shinji's thumbs-up, Minato, knowing he couldn't escape this, fell silent.
"Wasn't Teacher Kill supposed to teach us?" Karin pouted, clearly dissatisfied with the arrangement.
Kimimaro frowned as well, though he didn't voice his displeasure like Karin. Haku, on the other hand, accepted anything Shinji decided with calm acceptance.
Am I being disliked already...
Minato felt an inexplicable sense of grievance.
"This time, I've set your range of activity within a 500-meter radius around me. Isn't that considerate?"
Considerate? It's just unpaid labor! Minato thought to himself.
The special contract imposed unilaterally wasn't just about limiting his range; he couldn't have any ulterior motives or do anything against Mr. Anli.
Trying to exploit a loophole to take Mr. Anli back to Konoha was impossible!
Even the summoning technique didn't work beyond 500 meters; it felt like his world was compressed into a 500-meter bubble.
"By the way, do you really want to go back to Konoha? If you do, we can go together~"
Hearing this, Minato's expression froze. Though he wanted to see his son, he knew that bringing Shinji along would spell disaster for Konoha.
Mr. Anli was just too dangerous!
...
"Question time. Karin, who was created by the gods to suppress humanity but ultimately turned against them?"
"The king of Uruk, Gilgamesh!"
"Time period?"
"Um... around six thousand years ago."
"Okay, next, Haku. Summarize Gilgamesh's life."
Karin sighed in relief and sat down. Haku stood up and began, "Gilgamesh, six thousand years ago, during a transitional period for humanity, when the gods left the earth and humans began to dominate the world. In that era, Gilgamesh, as a king..."
Nearby, dressed as a househusband, Minato listened intently to this fantastic, unheard-of history while stirring a batter.
After all, the known history in the ninja world only spanned a thousand years, with no records or traditions from earlier times.
The constant warfare and other factors likely erased older histories.
The oldest known history in the ninja world was the Six Paths Sage bringing peace, which most people thought of as just a myth.
"Good answer. Now, it's your turn to ask questions. If you have any questions about this period, raise your hand."
"Um..."
Seizing the chance, Minato raised his hand, but before he could speak, Shinji interrupted.
"You're not a student. Focus on cooking."
Minato: ...
