Naruto : Back to the Past

As Naruto strolled toward his home, he couldn't help but reflect on his recent experiences. "It's only been three days since I arrived in this world, and I'm already settling in so well," he thought. The idea that he had managed to start anew and organize his life in such a short time. However, this wouldn't have been possible without Kushina. 

The thought of his mother waiting for him at home brought a genuine smile to his face. Living a life with his parents, something he had always dreamed of, was now a reality. It was like stepping right into the happy life he had always pictured in his mind.

"Back in my old world, I used to dislike going to the Ninja Academy, but here, it feels different. I actually enjoyed my time at the Academy today." In his previous life, Naruto wasn't fond of studying or attending the Ninja Academy. But after his first day in this new world, he felt a change in his attitude. Although he still wasn't keen on studying, his perspective was shifting.

"Studying isn't as tough as I thought it would be." He was pleasantly surprised to find that he could easily understand and keep up with everything the teachers explained in class. The idea of getting good grades now seemed within his reach, a possibility he hadn't considered before.

Finally, Naruto arrived at his home. 

Click!

"I'm home...!!!" he announced as he opened the door.

"Welcome back!!!" came a cheerful response, and suddenly, a figure leaped towards him. Quickly, Naruto put down his bag and opened his arms wide to catch the person.

It was his mother, Kushina. She wrapped her arms around his neck in a warm, tight hug. They stayed like that for a few seconds, enjoying the moment, before gently pulling away from each other.

"So, how was your first day at school?" Kushina asked him, her face beaming with a motherly smile.

"It was really fun. A lot of interesting things happened today at school." Thinking back on the day's events, Naruto couldn't help but let a big smile spread across his face. 

Naruto settled down in the living room, making himself comfortable while Kushina headed to the kitchen to fetch something for him to drink.

After a moment, Naruto called out, "Mom, why didn't you tell me about Sasuke not being in this world? Or about Hanabi being Hinata's twin sister?" He was curious since these were significant details, especially considering the reputations of the Uchiha and Hyuga clans. As a skilled and knowledgeable ninja, Kushina surely would have known these things.

Kushina reappeared from the kitchen, holding a glass of freshly made mango juice. "I thought it would be more interesting for you to find out on your own. Were you surprised?" she asked with a knowing smile.

"Yes, I was really surprised," Naruto confessed. The memory of his astonishment upon learning these unexpected facts, particularly about Sarada, was still vivid in his mind.

"Thank you, Mom." Naruto finished the glass of mango juice in one gulp. After drinking the cold juice he felt refreshed. 

"Why don't you go and take a shower? After a shower, we can begin your training." Kushina suggested. 

This is the reason why Naruto didn't go to train with Hinata but rather returned home so early.

Scene change____

Kushina and Naruto were now seated together in the living room, ready to start a special kind of training. Naruto, being part of the Uzumaki clan, was about to learn about Fuinjutsu, a unique skill closely associated with his heritage.

Kushina explained that in 180 days, a significant change would occur in Naruto, marking his full emergence as a pure-blooded member of the Uzumaki clan. Even Kushina wasn't completely sure what this transformation would entail. Considering Naruto's already impressive strength from his training in his previous world, Kushina didn't see the immediate need to train him further in Ninjutsu. That could wait until after these 180 days, once he fully embraced his Uzumaki lineage.

For the next six months, Kushina planned to teach Naruto as much as she could about Fuinjutsu. This knowledge was passed down to her from Mito Uzumaki and the elders of their clan. Sadly, the Uzumaki clan no longer existed as it once did, and with it, the widespread practice of Fuinjutsu had dwindled. This art form was a defining feature of the Uzumaki clan.

As a member of this distinguished clan, it was important for Naruto to learn about Fuinjutsu, not just for himself, but so he could pass on this valuable knowledge to future generations of Uzumaki. It was a way to keep the legacy of his clan alive and thriving.

Fuinjutsu wasn't just about creating seals; it was a powerful tool in battles too. Naruto, with his vast reserve of chakra, was ideally suited for using Fuinjutsu. High-chakra techniques that would drain others were manageable for him, meaning he could deploy these tactics in battle without needing help, potentially overpowering his enemies.

With this in mind, Naruto's training in Fuinjutsu under Kushina's watchful eye began.

Learning Fuinjutsu required a solid foundation in calligraphy, which was something entirely new to Naruto. Since he had never used a calligraphy brush before, his initial attempts were quite clumsy. Kushina dedicated their first day of training to practicing calligraphy, guiding Naruto through hours of meticulous work.

To speed up his learning, Naruto came up with a smart strategy. He created 30 shadow clones, each one practicing calligraphy just like him. The clever part of using clones was that when a clone vanished, all the knowledge and experience it gained went back to Naruto. This meant with 30 clones, he was effectively multiplying his learning speed by 30 times. He would have made more clones if there had been extra brushes available, but they had to work with what they had.

Next morning,

This morning, things were pretty normal for Naruto. Kushina hadn't stayed in his room overnight, and when he went downstairs, he found breakfast already laid out on the dining table.

"Good morning," Kushina greeted, busy preparing Naruto's lunchbox.

"Morning, Mom," Naruto replied, noticing a cheerful glow about her. His eyes then fell on her outfit – she was dressed in her Jonin uniform. She wore the classic leaf village green vest and her forehead protector. Her long, red hair was tied back into a neat ponytail, making her look both youthful and radiant.

"Mom, are you going out today?" Naruto asked curiously. He had thought that Kushina had retired from being a ninja, so he was surprised to see her in her Jonin gear again.

"From today onwards, I am going to start my new job," Kushina told him with a playful wink. 

"Start a new job?" Naruto was surprised. It's not like his mother lacked money or anything. Money was the last thing that Kushina Uzumaki lacked. So he couldn't understand why she was suddenly taking a job. 

"What kind of job is this?" Naruto curiously asked as he started eating. 

"You will know very soon." Kushina mysteriously said. Seeing Kushina being so mysterious, Naruto did not press his mother for any answer. Since she has said it, he will get the answer very soon. 

Once Naruto was done with breakfast, he did not waste any time since he had to reach the Academy in time. Otherwise, Iruka-sensei was definitely going to punish him. Naruto always has been the late student in his previous world but he didn't want to be like in this world. 

"Goodbye, Mom." With his school bag, Naruto started running towards the Academy building. Using his strength, Naruto easily managed to jump to the roof of a house. He then jumped from one roof to another. Naruto moved so fast that he essentially became a blur. He arrived in front of the Academy building within just a few minutes.

As soon as Naruto arrived at school, he made sure to say hello to Hinata, Ino, Sakura, Sarada, Hanabi, and the boys. Sarada, however, just gave a little huff and didn't reply. Naruto wasn't bothered by this; he knew it would take some time for Sarada to warm up to him. He then spent a few minutes chatting with Shikamaru and the others, until the sound of the school bell rang through the halls.

At the bell's signal, everyone headed back to their seats, getting ready for the day's lessons.

Their homeroom teacher, Iruka-sensei, walked into the classroom with a look that was a mix of seriousness and emotion. This unusual expression on Iruka's face made the students curious, wondering what could be making their teacher look so emotional this early in the day.

"Good morning, everyone!" Iruka greeted them with more gravity in his voice than usual. "Today, I have a very important announcement to make." He scanned the classroom, making sure no one was missing. Seeing that everyone was present and on time, a hint of satisfaction appeared on his face.

As Iruka-sensei made his announcement, Naruto and the rest of the class looked around at each other, all wearing expressions of surprise and confusion. Naruto caught Sarada's eye, and they both shared a puzzled glance. Scanning the room, it was clear that everyone was just as baffled, wondering what Iruka-sensei's words could mean.

Naruto's attention was drawn to Hanabi, who had activated her Byakugan, the unique ability of her clan that allowed her to see things others couldn't. He couldn't tell what she was looking at, but her expression was one of utter shock as she focused intently on the classroom door.

"I have enjoyed being your homeroom teacher for the past five years," Iruka continued. "But I believe it's time for me to step aside and let someone with even greater skills take my place." This revelation left the whole class in a state of shock.

"Are you retiring, Iruka-sensei?" Sakura asked, her voice reflecting the surprise felt by everyone.

"No, I'm not retiring. Teaching is my life's work. I will still be here at the academy, and I will still teach you. But I won't be your homeroom teacher from now on," Iruka clarified, his tone steady but filled with a hint of emotion.

I don't want you bore you guys by writing the training arc part. Especially for the Fuinjutsu training part, there really isn't much to write. [I don't want to write it just to increase the word count of the chapter.]

Due to his bloodline purifying, Naruto's height is going to increase and he is going to become more handsome.
