Naruto: Getting Observation Haki By Sacrificing The Byakugan

This was exactly what Kawaki Aoba intended: to allow Shinno to enjoy the same treatment as the Second Hokage—Senju Tobirama.

As the former leader of the Sky Ninja, Shinno was already dead. But in the future, he could shine under Konoha's name. His forbidden technologies—such as artificial Tailed Beast systems—would eventually be integrated into Konoha's arsenal.

However, to avoid an identity crisis or psychological breakdown, Shinno would need a transitional period.

Thus, the host body prepared for him couldn't be as mature as Tobirama's reincarnation had been. Ideally, he would be reborn as a student at the Ninja Academy—or even younger.

Of course, this plan was contingent upon finding a suitable vessel. If no proper body was available, Kawaki Aoba would not endanger Konoha's future generations by using an unsuitable host.

Having transformed Shinno into a soul orb, Kawaki Aoba stored him inside the Devouring Pouch. Along with it, he sealed Shinno's physical body. Though devoid of a soul, the body was in a state of suspended animation. But such a state wouldn't last forever—it would eventually decay into a true corpse.

After dealing with Shinno, Kawaki Aoba didn't leave right away. He had more pressing matters to address.

With a thought, two glowing spheres appeared atop the altar.

These were the Flesh Activation Secret Technique and the Dark Medical Ninjutsu—forbidden arts he had just extracted from Shinno's memory.

Rather than offering them to the system separately, Kawaki Aoba chose to merge the two into a single sacrifice.

Though distinct, the two jutsu were complementary, forming a cohesive field of biological manipulation. Sacrificing them together might result in a greater reward than if offered individually.

As familiar divine light bathed the altar, Kawaki Aoba waited with anticipation.

When the light finally faded, he saw what he had received: the power of the Horse Talisman.

This was the second Talisman power Kawaki Aoba had acquired. The Horse Talisman granted healing and regeneration, making it one of the most versatile abilities among the 12 Talismans.

With it, Kawaki Aoba would become effectively immune to all forms of physical injury and negative status effects.

Negative states?

The strain from using the Kaio-ken (King Kai Fist)—which amplified strength at the cost of bodily damage—definitely counted as such. That meant...

A bold idea struck him.

He tested the Talisman's ability, and the results were astonishing. Instant regeneration—pure, overwhelming healing power. Even the Great Red Pill, with its potent medicinal effect, couldn't match this level of immediate recovery.

The Horse Talisman could replace all recovery methods in high-risk combat. Kawaki Aoba was more than satisfied.

Originally, his plan was to annihilate the remnants of the Sky Ninja entirely. But with Shinno gone, the remaining followers were nothing more than scattered threats. Their so-called Zero-Tails—still an unstable and incomplete creation—would never amount to a viable weapon.

And besides, there were better ways than handling things personally.

He could let others do the work—borrow someone else's blade to clean up the mess. This would provide plausible deniability. If Shinno ever investigated his own past after reincarnation, Kawaki Aoba would have an explanation prepared.

Of course, Kawaki Aoba could have done this cleanly and quietly himself, but it would waste valuable time.

And wasting time was something Kawaki Aoba had no intention of doing.

In the next instant, he teleported back to Konoha.

Upon arrival, he summoned Senju Tobirama, and from the Devouring Pouch, took out both the soul orb and the lifeless body of Shinno.

He then explained everything to Tobirama—Shinno's background, his Sky Ninja technologies, and the plan to reincarnate him under Konoha's supervision.

Tobirama listened calmly, his eyes analyzing the orb held in Kawaki Aoba's hand.

> "Flesh Activation Jutsu, Dark Medical Ninjutsu, and the technology to artificially replicate Tailed Beasts... These are indeed advanced techniques. A man who developed them has value. I agree—his reincarnation can serve Konoha well."

He paused briefly before continuing.

> "As for the remaining Sky Ninja, I'll take care of them. I'll make sure the trail goes cold—no links back to Konoha. Just enough clues to imply a neutral third party."

Then, Tobirama's expression grew grave.

> "But Aoba... there's another matter. The other four Great Ninja Villages—Kumo, Kiri, Suna, and Iwa—have been communicating covertly again. Something is brewing. I compiled the intel just before your return. Take a look."

Caught off guard, Kawaki Aoba accepted the dossier. He had hoped to delegate more work to Tobirama—but now he found himself burdened again.

The intel nearly made him blurt, "Good heavens!"

The four Great Ninja Villages were becoming disturbingly unified. Their secretive coordination was no longer simple cooperation—it bordered on full-blown consolidation.

Anyone unaware of the history might think they were merging into a single superpower.

Kawaki Aoba knew their motives were darker. Each wanted to seize Tailed Beasts from the others. Their alliance was one of distrust and mutual exploitation.

But Tobirama... to gather this level of intelligence? Truly formidable. When it came to internal control, Kawaki Aoba was unrivaled—but for espionage beyond Konoha, Tobirama was unmatched.

This briefing served a dual purpose: to inform Kawaki Aoba and to keep him busy.

Tobirama, after all, disliked seeing him idle. As the de facto ruler of Konoha—the uncrowned king—Kawaki Aoba had power few could match. But doing nothing all day wasn't acceptable.

And deep down, Kawaki Aoba could sense another layer beneath Tobirama's words.

It was subtle—but there was dissatisfaction. A protest, perhaps. After all, reincarnating Tobirama into a branch of the Uchiha Clan had been... problematic. For a man of Tobirama's pride, living as a civilian genin—even temporarily—had been a test of patience.

Kawaki Aoba chuckled awkwardly.

Indeed, he had dug quite a pit for the Second Hokage.

Although Konoha's system was rigid and deeply traditional, as long as Senju Tobirama possessed enough strength to protect himself, he could reveal his true identity much like Hiruzen Sarutobi might have in his prime. Given the deep bond they once shared as master and student, verifying his identity wouldn't be difficult.

When the time comes, whether to reveal his identity outright or reestablish his influence as a trusted advisor to the Hokage, Tobirama has options.

However, being reincarnated as an Uchiha presents a unique and insurmountable problem. Whether because of his historically strained views toward the Uchiha Clan or the delicate balance of the village's political structure, Tobirama Senju absolutely cannot expose himself.

Otherwise, no matter how carefully things are planned, chaos would erupt, and the consequences would be severe—exactly what Tobirama seeks to avoid.

This is why Tobirama continues to act as a behind-the-scenes asset for Kawaki Aoba, even though Hiruzen Sarutobi has started to grow suspicious of recent developments.

Even Hiruzen's quiet withdrawal from public life and his return to the Sarutobi Clan may have been subtly influenced by Tobirama's presence.

Every event is intertwined, with ripples both large and small. Kawaki Aoba reflects on this and silently praises his own foresight.

Everyone seems to be getting what they want. Everyone is looking toward a brighter future.

Ahem—back to the present. Kawaki Aoba browses through the latest intelligence and quickly sketches a plan in his mind. "Aren't all these players hiding their own agendas?" he muses. "Then I'll simply ride the wave."

A golden opportunity presents itself—the death of the Fourth Raikage. There is great potential to leverage this moment.

This isn't about sowing discord, but about applying the right pressure so the other villages feel compelled to unite.

If necessary, even making Konoha the common threat isn't out of the question.

Kawaki Aoba laid out his entire strategy before Tobirama Senju.

The Second Hokage frowned as he listened, and finally spoke:

"Aoba, are you suggesting we manipulate the other four villages into reviving the Ten-Tails, then frame them for trying to destroy the shinobi world—and eliminate them all in one strike?"

"Exactly," Kawaki Aoba replied without hesitation. "It's simple and brutal, but it's also extremely effective. A complete, one-shot solution."

Tobirama drew a deep breath and continued, "And what of the bigger threats? Like Madara Uchiha?"

At that, Kawaki Aoba's expression grew grave.

"Of course I've considered Madara Uchiha. He's arguably the greatest threat of them all. If the Ten-Tails is revived, he'll almost certainly appear."

A cold aura began to emanate from Tobirama as he waited for the real plan—some hidden ace Kawaki Aoba must have prepared to face Madara.

But what came next left him dumbfounded.

"To make sure I have the strength to deal with Madara, the Ten-Tails, and any worse threats, I need to focus entirely on improving my own power—for now and the foreseeable future.

So, Second Hokage, I'll leave the village's affairs to you. That includes promoting a strategic alliance among the remaining great ninja villages."

Tobirama Senju: "...???"

What the hell? He'd expected some complex contingency plan or dark secret weapon, not more work shoved onto his plate.

Was this guy just delegating everything to him again?

What made it worse—he couldn't refute the logic.

Strengthening oneself in anticipation of global crisis was a valid priority. But Tobirama couldn't shake the feeling that Kawaki was just using that as an excuse to avoid administrative headaches.

After all, no rational person would push for the revival of the Ten-Tails unless they were extremely confident in controlling the outcome.

It was clearly a ploy to eliminate hidden threats before they matured.

But what could he do? He couldn't overpower Kawaki Aoba—at least not without destabilizing Konoha further.

So, Tobirama resigned himself and accepted the burden once again.

For Konoha's sake, he told himself.

As Tobirama left, Kawaki Aoba sighed in silence. He felt a little guilty. But the capable should shoulder more responsibility, and everything he did was ultimately for the benefit of the village.

A stronger Konoha benefits everyone. And since Konoha is tied to him—if he grows stronger, so does the village.

That logic, in his eyes, was flawless.

Besides, hastening the Ten-Tails' revival wasn't a reckless gamble. Kawaki Aoba now possessed the Horse Talisman—a miraculous relic.

He had just tested its healing abilities, and the results were astonishing. The talisman restored one to their peak condition in an instant: healing injuries, curing illnesses, reducing fatigue, and replenishing chakra—all simultaneously.

There was no need to wait for chakra to recover like with traditional red and blue pills.

What came to Kawaki Aoba's mind first wasn't eternal combat endurance—it was the ability to continuously "milk" chakra from Son Gokū.

Previously, there had been a time limit due to chakra exhaustion. But now?

The Horse Talisman reset that timer instantly.

With this tool, Kawaki Aoba estimated that he could extract everything he wanted from Son Gokū within just a few days.

"Heh heh heh... Son Gokū, hold on just a bit longer. Your nightmare is almost over," he chuckled darkly.

This next move would rival the capture of four Soul Hall Elders.

Time passed steadily, and ambitious figures across the shinobi world began to act.

Among them, the most active was Ōnoki of Iwagakure. Through secret diplomacy and subtle pressure, he had already swayed Rasa of Sunagakure and Yagura—the Fourth Mizukage, whose will was often manipulated.
