Naruto: Getting Observation Haki By Sacrificing The Byakugan

Otherwise, Orochimaru would truly be in danger.

Though Orochimaru had never feared danger, he detested the thought of dying without understanding the cause.

"With an attack like that... Danzo should have been dead. Unless, of course, he prepared backup measures. It'll be interesting to see if he manages to draw out more of the Rinnegan's capabilities."

Orochimaru licked his lips with his serpentine tongue, thinking of the grotesque arm full of Sharingan he had transplanted onto Danzo years ago.

He suspected the battle between Danzo and the Rinnegan wielder wasn't over yet.

And indeed, Orochimaru's instincts were sharp.

Above the leveled ruins of a once-thriving town, Danzo's form emerged seemingly from nowhere. His lone Sharingan eye flickered erratically, and his expression was one of horror and disbelief.

He trembled, taking in the desolation around him.

"Impossible... Where is my Impure World Reincarnation army? Reanimated shinobi are immortal! How could they have been wiped out so easily?"

While Edo Tensei resurrects immortal ninja, its user is still vulnerable. And Nagato's Chibaku Tensei–no, this was more akin to Shinra Tensei, the enhanced "Super Almighty Push" he had once used to level Konoha—was an indiscriminate force. Everything within its radius—structures, terrain, and people—had been flattened in an instant.

Even Danzo had not been spared. He only survived because of the Izanagi, a forbidden Uchiha technique that rewrites reality in exchange for blindness in the Sharingan used. Danzo had activated it in advance, as insurance.

But now, with his reanimated army obliterated and facing Nagato alone, he was in a dire situation.

As Nagato descended from the sky, the tremors in Danzo's hands betrayed his fear. The sheer destructive scale of the Shinra Tensei had left a deep psychological scar.

Desperate, Danzo tore off the seals on his right arm, revealing the dozen Sharingan embedded in it—his last resort, each eye a potential activation of Izanagi. He was ready to fight for his life.

At that moment, regret flooded him. He should never have come in person. If he had another chance, he would never have risked himself so recklessly.

"You… You're Shimura Danzo, from Konohagakure," Nagato said coldly, his voice calm as he stepped forward.

Danzo's identity was well-known in the underground world; his position as a Leaf elder and head of Root made his face recognizable to those who dealt in information and assassinations.

"To have survived my Shinra Tensei… You live up to your reputation. But survival isn't an excuse for your crimes. Since that attack didn't kill you, I'll ensure you experience true pain now."

Perhaps remembering the Leaf shinobi who had killed his parents, Nagato's killing intent surged uncontrollably as he faced Danzo.

Danzo backed away instinctively, but his years of battlefield experience allowed him to keep a level head. Under pressure, he quickly assessed the situation.

"You used a large-scale technique just now. That kind of chakra output… you must be weakened now. Can you still wield that power again?"

Danzo's words were a calculated probe.

If he got no response, he would retreat immediately. With multiple Sharingan left, each capable of activating Izanagi, he believed he still had a sliver of hope, however slim.

But unexpectedly, Nagato hesitated—a flicker of surprise passed through his Rinnegan.

It was subtle, but Danzo caught it with the insight of his Sharingan—though perhaps not even a three-tomoe Sharingan could have detected it without keen focus.

Danzo's confidence surged. He had been right—using such an overwhelming technique had taken a toll on Nagato.

Faced with a choice between retreating and gambling, Danzo didn't hesitate. Greed for the Rinnegan's power burned brighter than his fear.

He charged forward.

Across from him, surprise flickered in Nagato's eyes. He hadn't expected Danzo to come at him head-on after witnessing such devastation.

Still, Nagato didn't flinch. So what if Danzo guessed correctly? After using the enhanced Shinra Tensei, he couldn't immediately use it again—Nagato was aware of that. But the Rinnegan had many other abilities.

Nagato raised a hand, intending to use the Preta Path to absorb chakra or pull Danzo in using the Deva Path's gravity.

But Danzo acted first.

"Wind Style: Great Breakthrough!"

A basic wind technique—but executed at the level of a seasoned elite Jōnin. A violent gust surged toward Nagato.

Nagato didn't evade. He conjured a chakra shield with a single hand sign.

Though it appeared to be a barrier made purely of chakra, it was actually a sophisticated sealing technique—a manifestation of the Preta Path's chakra absorption.

Danzo didn't recognize it.

The moment the wind attack struck the shield, it vanished as though absorbed into the void, not even causing a ripple. In fact, some of Nagato's chakra was restored in the process.

Danzo, poised to follow up with a kunai for a sneak attack, froze mid-step, stunned.

By the time he realized his plan had failed, it was already too late.

A gravitational force took hold of him—inescapable, crushing.

Nagato's eyes narrowed.

"The era of men like you… is over."

Shimura Danzo's body was hurled uncontrollably through the air toward Nagato. Mid-flight, Danzo's expression twisted in grim determination. Realizing he could no longer retreat, he summoned his last reserves of resolve. He would confront Nagato head-on.

At worst, he would die—but death wasn't yet final for him. Thanks to the power of Izanagi, he had more than one chance.

Clutching a kunai tightly, Danzo envisioned a decisive counterattack. But before the blade could reach Nagato's neck, a hand clamped down on his shoulder—Nagato's hand.

A wave of weakness overtook Danzo. His chakra surged outward, forcibly extracted. If this continued, he would be drained dry before he could act.

With no hesitation, Danzo activated Izanagi again, rewinding reality and negating his death.

Nagato narrowed his eyes, surprised. The chakra he had just absorbed left an odd impression—it was mixed and chaotic, yet strangely enticing. His body responded to it with an unnatural craving.

Why would my body want more of that chakra? he wondered. Danzo's chakra feels corrupted, but it also contains pure fragments... Yin and Yang chakra?

The thought lingered only briefly. The battle was not over.

Danzo's withered corpse, drained of chakra, collapsed to the ground. But moments later, the corpse shimmered, turned translucent—and vanished. Reappearing some distance away, Danzo stood with an unchanged expression, his body whole once more.

Nagato's gaze sharpened.

"What technique is this? Resurrection? Did you use this to survive my Shinra Tensei earlier?"

Danzo didn't respond. His previous death had calmed his thoughts, but also instilled caution. The Rinnegan's powers were overwhelming—Shinra Tensei, Universal Pull, chakra absorption—and there could be more he hadn't yet seen.

Though not afraid of death, Danzo knew it was wasteful to throw away his remaining uses of Izanagi for nothing. He locked eyes with Nagato, memorized his face, and turned to flee.

But escape was never an option.

"Banshō Ten'in."

Nagato extended his arm again, and gravity surged against Danzo, dragging him back.

He won't let me go, Danzo realized grimly.

To Nagato, Danzo was not just another enemy—he was a symbol of everything Amegakure had suffered under the great powers. A shinobi from Konoha. A known conspirator. A murderer of innocents during the Rain Country's wars. He had no right to mercy.

Danzo gritted his teeth. The kunai was useless. He reached for a jutsu—but he was pulled in too quickly to weave signs. The moment he was within reach, Nagato's hand touched him once more, draining his chakra again.

Useless… again, Danzo thought as his vision blurred.

This time, Nagato focused during absorption, sensing the unique signature of Danzo's chakra. There were fragments of Yin and Yang release—pure, potent, but faint. Not enough to empower him significantly, but intriguing. It was not chakra Danzo should possess naturally.

Nagato frowned. Is this related to Hashirama's cells? Or perhaps the Uchiha eye techniques?

He shook the thought away. He was still mid-battle.

Danzo, incredibly, revived again. The third use of Izanagi.

This time, his first act was to bite his thumb and slap his palm onto the ground.

"Summoning Jutsu!"

A massive beast emerged—the Dream Eater, a rare psychic summon with a grotesque, shifting body. It positioned itself between Danzo and Nagato.

Now shielded, Danzo hoped to buy time.

Nagato stared, momentarily intrigued. A psychic-type summon. Large, but nothing special.

The Dream Eater lunged—but the moment its eyes locked with Nagato's, it froze. Its pupils swirled and turned into the concentric circles of the Rinnegan.

One of the Six Paths: Animal Path.

Nagato had taken control of the summon effortlessly.

Danzo's heart sank. Yet another Rinnegan ability. And now, even his summon was gone.

Despair crept in. He had watched the Rinnegan neutralize everything he had: physical attacks, ninjutsu, chakra reserves, and now even his last defense. What hope was left?

"Am I truly going to die here today? No… I can't. I'm supposed to be the Hokage… I can't die yet!"

Danzo shouted his defiance, but the only response was the cold silence of his enemy.

Under the weight of his impending defeat, something shifted within Danzo. His survival instinct flared violently.

"You've left me no choice…"

Behind the still form of the Dream Eater, Danzo bit his finger once more and began weaving a rapid set of hand seals.
