Reborn into Naruto World with Tenseigan

Yui remarked, “It’s truly incredible that Naruto can stick to the Spartan training program you created for him.”

As they left Naruto’s room, Kuroto nodded in agreement and added, “Indeed, but we must recognize that this is his current limit. Pushing him further would be detrimental.”

Kuroto went on to highlight Naruto’s remarkable Uzumaki physique and strong willpower. However, he emphasized that everyone has their limits, and Naruto has reached his with the current training program. Going beyond this point would risk harm.

Yui sighed, expressing the difficulty of the training, saying, “Even at this level, it’s extremely challenging. I could never impose such training on Hinata-chan or Shion-chan!”

Kuroto smiled in response, choosing to remain silent.

Kuroto’s decision to subject Naruto to an exceptionally rigorous and extensive training regimen stemmed from a crucial realization. He had long ago discovered that the Nine-Tails sealed within Naruto were covertly providing support, ensuring his involvement in the training.

This wasn’t a rare occurrence. On numerous occasions, Naruto found himself at the brink of exhaustion, only to suddenly regain energy and persevere through the training. This was attributed to the healing effect of the Nine-Tails’ chakra, a phenomenon that occurred repeatedly. Kuroto took advantage of this unique assistance to push Naruto beyond ordinary limits in his training.

While Naruto remained oblivious to the subtle interventions of the Nine-Tails, Kuroto, being astute, couldn’t help but notice. The repeated occurrences were too frequent to be overlooked, indicating that the Nine-Tails were actively aiding Naruto during his training.

It’s reasonable to assume that the Nine-Tails harbored deep resentment toward Naruto. After all, it was forcefully sealed within Naruto’s body against its will by Naruto’s father, Namikaze Minato. Despite this inherent hostility, the Nine-Tails paradoxically played a role in supporting Naruto’s efforts, a dynamic not lost on Kuroto.

In usual circumstances, the Nine-Tails would have harbored resentment towards Naruto and likely imposed restrictions on him. However, this wasn’t the case. Kuroto speculates that the Nine-Tails might have become aware of the Akatsuki Organization and their plan to capture all the Tailed Beasts. The Akatsuki aimed to revive an ancient weapon capable of devastating entire countries. This awareness could be a reason why the Nine-Tails didn’t oppose Naruto as expected.

About seven months ago, Naruto faced a near-capture by the Akatsuki Organization. During this incident, the Nine-Tails likely discovered that the leader of Akatsuki, Uzumaki Nagato, possessed a pair of Rinnegan—the same eyes as the Sage of Six Paths. This knowledge would have made the Nine-Tails aware of the significant threat posed by Nagato. Consequently, the Nine-Tails should understand the heightened danger outside and recognize that its current sealed state within Naruto’s body is the safest place in the Shinobi World. Anywhere else, and the Akatsuki Organization would likely immediately pursue and capture it.

Certainly, the Nine-Tails may boast about being the strongest among the Tailed Beasts, but it should recognize its limitations against formidable foes like Nagato, who possesses a pair of Rinnegan, and ‘Uchiha Madara’ with both Mangekyou Sharingan and Wood Release abilities. Despite its arrogance, the Nine-Tails lacks the sufficient power to contend with such formidable adversaries.

In a somewhat ironic twist, the place that the Nine-Tails despises the most has ironically become the safest haven in the world. Kuroto pondered this amusingly, wondering about the Nine-Tails’ sentiments in this peculiar situation.

Simultaneously, if anything were to happen to Naruto, or if he were captured by the Akatsuki Organization, the Nine-Tails wouldn’t have a promising future either. Thus, driven by its instinct to survive, it seems to be opting for the lesser of two evils by covertly supporting Naruto’s training. Presumably, it hopes that the stronger Naruto becomes, the more challenging it will be for the Akatsuki Organization to capture him, ensuring Naruto’s safety.

Kuroto sighed, expressing regret that the Nine-Tails doesn’t openly acknowledge its actions. However, he noted that this is in line with the Nine-Tails’ Tsundere nature – outwardly dismissive but inwardly caring. Despite the snorts of disdain, the Nine-Tails do seem to harbor concern for others.

…

Following some conversation, Yui headed to her parents’ home for the night. It was set to be a girls-only evening with Hinata and Shion, a special occasion as they were all on the brink of graduating.

With Yui away, Kuroto returned to his bedroom and retrieved his Lightning Chakra Clone from a concealed cabinet. Throughout the seven months spent training Naruto and managing the responsibilities of the Hokage, Kuroto remained dedicated to advancing his Project Godhood.

Following the renovation, upgrade, and transformation of the Ancor Vantian, Kuroto initiated the restoration process for the Giant Tenseigan of the Hyuga Clan. Having been sealed for nearly three hundred years, its condition was far from ideal, requiring significant attention before Kuroto could effectively utilize it. However, the restoration proved to be time-consuming, and despite seven months of effort, the Giant Tenseigan had only progressed from a weakened state to a more normal condition.

Given the limited options available, Kuroto viewed this slow recovery as a positive development. While the process was gradual, the fact that the Giant Tenseigan was showing signs of improvement was considered a boon in his eyes.

As the recovery of the Giant Tenseigan commenced, Kuroto conducted a series of experiments. These experiments were deliberately designed with limited chakra consumption to avoid imposing excessive strain on the Giant Tenseigan.

In these experiments, Kuroto attempted to absorb the Byakugan Chakra from all members of the branch family of the Hyūga Clan using the Caged Bird Cursed Seal. He refrained from such attempts when the Giant Tenseigan was in a weakened state due to concerns about potential loss of control, which could have resulted in harm to the entire branch family.

Now that the Giant Tenseigan had returned to a normal state, Kuroto felt it was safer to attempt such experiments. The objective was to assess whether the Giant Tenseigan could function as a hub, connecting to the consciousness of all members of the Branch Family. After a few attempts, he confirmed that indeed it could.

Simultaneously, Kuroto realized that, with the assistance of the Giant Tenseigan of the Hyūga Clan, he had the capability to take anything he desired from all the members of the branch division who were bound to it through the Caged Bird Cursed Seal.

In the second experiment, Kuroto investigated the possibility of shielding a person from the Caged Bird Cursed Seal. He confirmed that it could indeed work, providing both temporary and permanent protection. Upon discovering this capability, Kuroto felt tempted to shield individuals like Yui, her parents, Neji, and his parents. However, after careful consideration, he opted against it.

The reason behind his decision was the potential danger associated with the disappearance of the Caged Bird mark from the forehead during the shielding period. In the current situation, this could pose risks to the individuals involved. Instead, Kuroto ensured that he maintained control over the Caged Bird for these individuals. Given the recent instability of the leaders in the main family, he didn’t want to take any unnecessary risks.

In addition to his studies on the Giant Tenseigan of the Hyuga Clan, Kuroto began the development of the ‘Type III Biological Armor.’ This new armor was based on the data collected from the ‘Type II Biological Armor’ but featured improved stability and a more refined design. It promised greater comfort for the wearer.

One standout characteristic of the ‘Type III Biological Armor’ was its anti-reconnaissance ability. It could effectively block the penetrative vision of the Byakugan and make it challenging for individuals without exceptional skills in presence sensing to locate the wearer.

The ‘Type III Biological Armor’ boasts an additional special characteristic—it can render the wearer invisible. This feature drew inspiration from Hayate’s invisibility Jutsu. However, the current invisibility mode is not yet perfected; Kuroto anticipates that it will take at least one more generation, possibly with the ‘Type IV Biological Armor,’ to achieve flawless invisibility.

Now, the question arises: why is Kuroto creating multiple Biological Armors? The answer lies in his desire to accumulate more experience with Hashirama Cells. By doing so, when the time comes to create the Yang Clone, he aims to minimize setbacks and complete the clone in one or two attempts. The development of various Biological Armors serves as a means to refine his skills and understanding of Hashirama Cells for this ultimate goal.

Setting the Yang Clone aside for the moment, Kuroto’s primary focus has been on the development of the Lightning Chakra Clone over the past seven months.

Through the Tenseigan Soul Descent technique, Kuroto transferred his soul into the clone lying on the bed. With his soul inside the clone, Kuroto stood up and moved around to acquaint himself with the body. This allowed him to engage in the clone’s cultivation training.

For the past seven months, this has been Kuroto’s routine. Nights are when he generally has free time. With Naruto sound asleep, Kuroto doesn’t have to worry about disturbances; Naruto is a deep sleeper, unlikely to wake up before morning due to the fatigue from training.

During these nights, Kuroto dedicates his time to training his Lightning Chakra Clone in his room, acquainting himself with the Lightning Chakra Nature. When he needs to undertake activities that might produce excessive noise, he opts to stealthily leave the village and find an isolated area for training. At times, he utilizes reverse summoning to reach the ‘Forgotten Island,’ a secluded spot perfect for training without the risk of being discovered.

Up to this point, the development of the Lightning Chakra Clone has been proceeding smoothly, and Kuroto is on the verge of reaching a point where he can shift his attention to creating a Lightning Chakra Nature-based Kekkei Genkai for the clone.

He contemplates developing the ‘Storm Release,’ a Kekkei Genkai formed by the fusion of the Lightning Chakra Nature and the Water Chakra Nature. Given that many shinobi from Kumogakure use this Kekkei Genkai, acquiring the necessary scrolls detailing its techniques is not a particularly challenging task.

With determination, Kuroto declares, “Well, let’s get to work,” as he begins to focus on the development of the Storm Release for his Lightning Chakra Clone.
