A Fourth Birthday Gift

After the incident involving the Kumogakure conspiracy, Kamizuki could no longer wait to learn the methods of chakra extraction and various ninjutsu.

He knew that if he wanted to survive happily and fulfillingly in this world of ninjas, without letting anyone dictate his life, there was only one way: he had to become incredibly powerful so that no one could control him.

Finally, another year passed—flowers bloomed and withered, spring turned to autumn—and the end of the year arrived once more. This meant that the birthdays of Hinata and Kamizuki were here again. Yes, they were finally turning four years old this year.

A four-year-old child on Earth might just be a little brat who had only recently started kindergarten, but in the ninja world, children from many ninja clans were already about to begin learning how to refine chakra.

The day finally arrived on December 27th, the fourth birthday of Hinata and Kamizuki.

Hiashi told the two of them to come to the family's training ground in the afternoon, promising to give them both a special birthday gift.

In truth, the moment he heard Hiashi say this, Kamizuki had already guessed what the special gift would be: he was going to teach him and Hinata how to extract chakra.

As a new human being who grew up in the 21st century, the era of the internet, if Kamizuki couldn't see through a simple ploy like Hiashi's, well, then the twenty-some years of his previous life would have been a complete waste.

In the years since his transmigration and rebirth, Kamizuki had spent enough time with Hinata to realize that she was indeed born with a shy nature.

Back when he watched the anime, Kamizuki always felt that Hinata's shyness was adorable and super cute.

But after transmigrating and becoming Hinata's twin brother, he realized that her shy personality could sometimes be a real headache.

After finishing lunch, Hinata and Kamizuki followed Hiashi to the training ground.

Once they arrived, Hiashi knelt on the wooden floor. Seeing the two children standing there looking naive and clueless, he gestured for them to sit down.

After they were both kneeling properly, Hiashi nodded with satisfaction. With a serious expression on his face, he spoke to them: "Today is your fourth birthday, and as your father, I have a special gift to give you."

Hearing Hiashi pull this routine again, Kamizuki felt speechless inside, thinking: This cheap father of mine, putting on such a serious face just to act cute—I really can't handle it!

Little Hinata, on the other hand, was perhaps truly innocent and simple-minded; she played along with Hiashi's routine, looking at him with a face full of anticipation.

Hiashi paused for a moment, observed the expressions of the two children, and continued: "This special gift is to teach you both how to refine chakra, as well as the basics of the Gentle Fist."

Kamizuki wore an "as expected" expression, while Hinata looked a little disappointed and unhappy, as if she were a child who had just had her favorite lollipop stolen by a creepy uncle.

Hiashi ignored their reactions and continued: "First, I must tell you what chakra is."

Chakra is a form of energy produced by perfectly fusing the various components of energy controlled by the human body. It is the source of power used to perform ninjutsu, genjutsu, taijutsu, or to create threads to bind opponents or cut through substances composed of chakra.

Its composition is as follows:

1. Physical energy extracted from each of the 130 trillion cells in the human body.

2. Spiritual energy cultivated through much training and accumulated experience.

After extracting chakra, one must perform "hand seals" to use "jutsu."

Hiashi paused briefly here, giving the two children, who were still quite young, a moment to slowly digest this information.

Then, he began to explain again:

There are two basic transformations of chakra: shape transformation and nature transformation.

Characteristics: There are generally five nature transformations of chakra: Fire, Water, Wind, Lightning, and Earth.

There are also two special nature transformations: Yin and Yang.

Yin-style chakra nature transformation includes, for example, the Nara clan's Shadow Possession Jutsu and the Yamanaka clan's mind-related ninjutsu.

Yang-style chakra nature transformation includes, for example, the Akimichi clan's Multi-Size Jutsu and medical ninjutsu.

The five nature transformations have mutual restraints: Fire beats Wind, Wind beats Lightning, Lightning beats Earth, Earth beats Water, and Water beats Fire.

After finishing this explanation, Hiashi let the two children take a break, while he had a servant pour him a cup of tea, resting as he drank.

After about ten minutes of rest, Hiashi called the two children, who were busy laughing and playing, back to continue their lesson.

Once they were back in their kneeling positions and had set aside their playful moods, Hiashi continued: "Next, I will teach you both the method for refining chakra."

Hearing this, Kamizuki's spirits lifted immediately; this was what he had been waiting for! Finally, they were getting to the main point.

Since I couldn't make it up even if I tried, let's just assume Hiashi has finished explaining how to refine chakra and has successfully taught the siblings how to do it.

Please don't scold or flame me, I beg you! Thank you.

Alright, I shouldn't stray too far from the topic. Let's get back to it.

After Hiashi explained the method of chakra refinement, he had Hinata and Kamizuki begin to slowly attempt to extract chakra themselves.

By the time Hiashi finished explaining all the knowledge related to chakra, it was already nearly three o'clock in the afternoon. Hiashi had originally thought that if these two children could successfully extract chakra even once within two days, it would be quite impressive.

Although Hiashi knew his son was a monstrous genius who might extract his first wisp of chakra by tomorrow morning, he didn't have the same expectations for Hinata; he would be very satisfied if she could cultivate a wisp of chakra within two days.

But something Hiashi never expected happened: Kamizuki lived up to his name as a "monstrous genius." That very day, in less than two hours, he successfully extracted his first wisp of chakra energy.

Kamizuki had taught Hiashi a lesson: there is nothing you can't do, only things you haven't thought of yet.

When Hiashi learned that Kamizuki had extracted chakra, he was still in disbelief. But when he activated his Byakugan and examined Kamizuki's body, he truly saw that tiny, insignificant wisp of chakra slowly flowing within him.
