The next day, Sasuke didn't have school, so Tōshirō was able to train with him.
Sasuke's round eyes stared at Tōshirō, curious about how he would guide him in his training.
Tōshirō put his hands in his pockets. "Before we officially begin, let me test how well you've been doing in school."
"What's the question?"
Sasuke looked ready for anything. He was a great student at the academy.
"What are the five basic nature transformations of jutsu?"
This was an easy question. Sasuke answered without hesitation, "Wind, fire, water, lightning, and earth."
Tōshirō nodded slightly. "Close enough."
As for Yin Release and Yang Release, Sasuke was too young to learn about them, so there was no need to go into detail.
Tōshirō pulled out a pre-prepared chakra paper from his pocket and held it out.
Sasuke was stunned. "Paper?"
"This isn't just ordinary paper; it's chakra paper."
"Chakra paper? What's it for?"
Seeing the confused look on his face, Tōshirō knew he had little to no experience with it.
Tōshirō gave him a brief explanation of how chakra paper could test a person's chakra nature.
After listening, Sasuke's eyes lit up. "I can't wait to try it."
Tōshirō handed it over, first teaching him how to use it, and then he tested it.
The chakra paper in Sasuke's hand wrinkled and burned.
Just as he expected. Tōshirō looked at him with approval. "You were born with both lightning and fire chakra natures. This will make it easier for you to master these two nature transformations."
"Lightning chakra nature?"
Sasuke looked at the half of the paper that had wrinkled, full of curiosity.
The Uchiha clan was known for their Fire Style, so he wasn't surprised that he had a fire nature. But the lightning nature was a complete surprise to him.
"Tōshirō-sensei, can you tell me a little about Lightning Style?"
Sasuke had officially become Tōshirō's disciple, so he had changed his name from "uncle" to "sensei," which sounded more intimate.
"Alright, I'll give you a brief overview."
Tōshirō showed a desire to teach. "Lightning Style Jutsu has powerful penetration and destructive power. In addition, it can sharpen the edge of weapons and stimulate the body, activating cells to enhance the body's reaction speed.
"From my personal point of view, Lightning Style is the most suitable nature transformation for combat among the five."
"Then, Tōshirō-sensei, are you going to teach me Lightning Style?" Sasuke was shocked by what he heard and immediately said that he wanted to learn it.
Tōshirō shook his head slightly. "Unfortunately, I'm not good at Lightning Style and can't teach you Lightning Style Jutsu."
Sasuke's lips turned down.
He got him all excited only to tell him that?
Facing Sasuke's resentful look, Tōshirō smiled. "Don't be mad. If you want to learn Lightning Style Jutsu, I can have Fugaku teach you. I remember he was also quite good at Lightning Style Jutsu, in addition to Fire Style. I think your talent for Lightning Style might have been inherited from your father."
At the mention of his father, Sasuke became a little reserved. "Just forget about my father; he's very busy..."
"Are you scared?"
Sasuke shook his head, doing his best to deny it. "No, I'm not..."
"Alright, I won't tease you anymore." Tōshirō smiled and then his expression became serious. "Instead of Lightning Style, this is the jutsu I really want to teach you."
With that, he held his left hand with his right wrist, cupping it, and a blue sphere appeared above his palm.
Sasuke's eyes were wide open. Even as a child, he knew that this jutsu looked very powerful.
"This move is called the Rasengan."
Tōshirō introduced it. To give his disciple a more intuitive feeling, he found a rock wall and slammed it with the Rasengan. With a loud bang and the dissipation of smoke, a huge hole appeared.
Sasuke was dumbfounded. "Tōshirō-sensei, I want to learn that."
"Hold on. Let me test you again. What kind of nature transformation do you think the Rasengan is?"
Tōshirō smiled slightly, forming another Rasengan in his hand for his disciple to observe.
Sasuke carefully looked around the Rasengan and said thoughtfully, "It's a strange jutsu. It doesn't feel like it belongs to the five basic nature transformations."
"I thought you were just going to guess randomly."
Tōshirō thought that if it were a certain someone, he probably would have just guessed randomly.
"Brother said that pretending to know what you don't know will give people a very frivolous impression."
Tōshirō looked at him with approval. "You and Itachi have a really good relationship."
Sasuke said innocently, "Of course we do."
Tōshirō didn't beat around the bush anymore. "You're right. The Rasengan is not one of the five basic nature transformations. It belongs to chakra shape transformation."
"Chakra shape transformation?"
It was too complicated to explain. Tōshirō showed him a couple of moves, using Ice Style to create an ice dragon that curled up next to them.
Ice Style: Ice Crystal Dragon Jutsu.
Sasuke had never seen such a jutsu and was completely stunned.
Tōshirō placed his hand on the ice dragon. "Did you see anything?"
Huh?
Sasuke had been so shocked that he was just now coming to his senses. "That's so cool, Tōshirō-sensei! What kind of jutsu is that? It doesn't seem to be one of the five basic nature transformations."
"This is Ice Style, my bloodline limit." Tōshirō introduced.
After his reminder, Sasuke remembered.
His sensei Tōshirō seemed to have three bloodline limits.
Seeing his disciple's eyes light up, Tōshirō said gently, "Do you want to ride it?"
"C-can I?"
"It's fine."
Having received permission, Sasuke eagerly climbed onto it, a joyful smile on his face.
Sasuke's smile was infectious, and it even affected Tōshirō. He smiled. Though he was more mature than a typical child, he was still a child...
"Sasuke, hold on tight."
Tōshirō reminded him. He formed a hand seal with one hand and manipulated the ice dragon to move. Sasuke was stunned, not expecting such a thing to be possible.
After playing with Sasuke and the ice dragon for a while, Tōshirō dispelled the Ice Crystal Dragon Jutsu.
"Aww, is it over?" Sasuke pouted, still wanting more.
Tōshirō said playfully, "I'm more impressive than your brother, aren't I?"
Sasuke pouted. "I still think my brother is more impressive."
Tōshirō clicked his tongue and said in annoyance, "And here I was, playing with you for so long."
"I wouldn't betray my brother for such a small thing."
Although Sasuke said that, his heart had already wavered.
Itachi often performed shuriken tricks in front of him, showing off his amazing skills. But no matter how good he was at shuriken, it couldn't compare to the visual impact of playing with an ice dragon.
Tōshirō shrugged. "Alright, let's continue with the next topic."
Sasuke perked up his ears and listened carefully.
"Broadly speaking, a jutsu is usually composed of two things: chakra nature transformation and chakra shape transformation."
"You can simply understand nature transformation as different chakra natures, such as wind, fire, lightning, ice, and so on. As for shape transformation..."
Tōshirō paused, looking at Sasuke, giving him the chance to answer.
Sasuke was stunned for a moment, then realized what was going on. With his quick mind, he immediately analyzed it from the literal meaning. "Shape transformation is the different appearances a jutsu takes, right? Like a cat, a dog, or even a dragon..."
Tōshirō nodded in agreement. "Yes, that's pretty much it."
Shape transformation isn't as simple as just changing the appearance. A master can instill a certain animal's will into the shape.
This is why the Wood Dragon Jutsu is so powerful.
Tōshirō had originally planned to study the Ice Crystal Dragon Jutsu in that direction, but after acquiring his soul flame, this kind of jutsu became less useful.
Tōshirō continued, "And the Rasengan is the pinnacle of chakra shape transformation. You can't see any chakra nature in it because it doesn't contain any."
Sasuke was in awe.
Tōshirō explained the principle of the jutsu to Sasuke and then taught him the training method.
He didn't expect Sasuke to master it at his age, but it was a good idea to start early.
He also wanted to see how talented Sasuke was.
The Rasengan was an A-rank jutsu, so Sasuke was a bit confused by what he was hearing.
"The best teacher is practice. You should try it first, and you'll slowly figure it out," Tōshirō said with a smile. "By the way, this jutsu is around A-rank. I don't expect you to master it now, so don't feel pressured."
Sasuke was stunned. "A-rank jutsu!?"
"That's a jutsu level that only Jonin can learn."
Sasuke's mind was a bit jumbled.
Wait, he was a child who had just started school, and this teacher was telling him to learn a jutsu of this level. Was this teacher a demon?
"If you think this jutsu is too difficult, I can change it for you."
Sasuke said firmly, "No, I'll stick with this one."
"Are you sure?"
"Yes. Tōshirō-sensei also said that the Rasengan is only chakra shape transformation. So if we add chakra nature transformation to it later, it will definitely become even more powerful."
"You're quite smart. That's great; I'm starting to like you more and more." Tōshirō laughed. "Then let's start with gathering chakra in your hand."
"Yes."
Sasuke replied and immediately began to train.
Tōshirō found a rock to sit on and watched him train with a serious expression. In his mind, he couldn't help but picture the future Sasuke using the Rasengan.
