Naruto: I am Uchiha Shirou

Land of Iron.

As the castle for the Five Kage Summit collapsed, the Five Kage and Mifune shouted in alarm and dodged for cover.

"Uchiha Shirou, this is your opponent."

With the roof collapsing, when four figures appeared, everyone present was instantly shocked.

Hiruzen Sarutobi, Danzo Shimura, Homura Mitokado, and Koharu Utatane—the legendary Konoha F4 from the era of the Third Hokage.

However, this time, the cracks on their skin and the black, ashen eyes made everyone gasp in horror.

"This is Edo Tensei!"

Although it was the first time seeing it, the experienced Onoki instantly recognized it based on previous information.

After all, Edo Tensei had appeared before during the Chunin Exam disaster in Konoha.

At this moment, masked Uchiha Obito let out a cold laugh as if he were toying with the five strongest Kage in the ninja world.

He stood loftily above, and the four Edo Tensei resurrected in front of him slowly lifted their heads, revealing the unique eyes of the Edo Tensei.

"What is this!?"

Hiruzen Sarutobi looked in astonishment at the scene before him, then looked down at his hands, instantly realizing he'd been summoned by Orochimaru's jutsu.

"Such an evil forbidden jutsu that manipulates souls!"

While Hiruzen was furious with the summoner, Homura, Koharu, and Danzo, upon regaining consciousness and seeing those before them, burst out in anger.

"Tsunade! Uchiha Shirou!"

"Hiruzen, after you died, Tsunade joined forces with the Uchiha Shirou and seized Konoha. She even exterminated the Sarutobi clan..."

"Hiruzen! Look at your precious student!"

What a scene—right upon appearing, the Konoha F4 immediately started infighting, even in death.

"What's going on?!" (Oh right, this world's Hiruzen who died in the Chunin Exam by Orochimaru.)

Hiruzen was dumbfounded to see his three old friends dead as well. Although they were old, dying was normal.

But the angry looks they shot at Tsunade—what was that all about?

Meanwhile, the cunning Onoki silently held back Kurotsuchi; wasn't this a perfect chance to test both sides' strength?

Akatsuki is no good, but is Konoha any less dangerous?

"What! Tsunade, how could you do this—joining hands with the Uchiha..."

Once Hiruzen learned that after his death, Tsunade seized Konoha and even wiped out his clan, he was instantly enraged.

"Shut up, you old fool!"

The moment she saw the Third Hokage, Tsunade couldn't help but shout.

"A bunch of old fools! Konoha fell to ruin because of you geezers!"

Suddenly, a thunderous crash sounded in the castle, and everyone could now see the battle outside through the blasted walls.

The Fourth Raikage, A, was fighting his own younger brother, Killer Bee.

Under Edo Tensei, Killer Bee had entered Eight-Tails mode and roared in anger:

"Aniki, I'm being controlled by Akatsuki! This Edo Tensei body has infinite chakra and stamina—you must seal me!"

Fourth Raikage A's face was full of tears; after seeing his brother die, he roared in fury.

"Damn Akatsuki! I will make you pay with your lives!"

The fight was about to explode. Battles erupted in the sky above the castle as well.

With a deafening roar, all the Kage and their guards leaped out.

Mifune was furious: "Damn Akatsuki!"

Meanwhile, the Konoha F4 (Sarutobi, Danzo, Homura, Koharu) joined forces with tremendous power.

Especially Homura and Koharu, who were filled with rage.

"Tsunade, now that my chakra and stamina are restored to my youth, I'll make you pay this time!"

Koharu stared venomously at Tsunade, her hatred from being killed boiling over. Now that she had her youthful power again, she was determined to take revenge.

Back then, she was chosen as Second Hokage's bodyguard, so her peak strength went without saying at least elite Jonin level.

"A bunch of trash."

At this point, Tsunade flung her cloak aside, cracking her knuckles, ready to strike—but Shirou smiled beside her.

"After all, we are Kage bodyguards. Let Hikari handle these old fossils."

At Shirou's casual words, Tsunade glanced at Hikari, snorted coldly, and nodded in tacit approval.

This attitude immediately caught the attention of Onoki, Gaara, and Mei Terumi.

Their eyes were filled with surprise and doubt. This young girl, though with the Uchiha clan crest, could she handle it at her age?

After all, her opponents were the legendary Konoha F4 from their peak, including The Professor Hiruzen Sarutobi and Darkness of the Ninja World Danzo.

Uchiha Hikari was a complete unknown—even Temari and Mei Terumi had barely heard of her.

Only Tsunade knew something, and that's why she agreed to see what this Uchiha, sealed away for a hundred years in the Warring States era and called the ultimate weapon by the Uchiha, could do.

"Hikari!"

"Yes, Lord Shirou!"

At this moment, many people's eyes flashed with intrigue, especially the Kage and their guards—gathering intelligence is any ninja's priority.

Just from this exchange, they could tell: the Fifth Hokage Tsunade gave the order, but Uchiha Hikari never responded.

Instead, when Shirou spoke softly, Hikari instantly nodded with resolve.

In other words, this Kage bodyguard, Uchiha Hikari, obeyed someone else's command, not the Hokage Tsunade's.

Meanwhile, Obito stared straight at Shirou, a cold sneer in his eyes. He slowly formed a seal, and instantly, a dozen more coffins emerged before him.

Forbidden Jutsu: Edo Tensei!

As the coffin lids fell, revealing the figures inside, many present were shocked.

"The Seven Ninja Swordsmen of the Mist! Plus the Second Tsuchikage, Fourth Mizukage, Third and Fourth Kazekage..."

As one Edo Tensei ninja after another emerged, masked Obito sneered.

"Edo Tensei—what a useful forbidden jutsu. Now, no one should be able to interfere, right?"

In that instant, the Edo Tensei resurrected opened their eyes, shocked to find themselves back in the living world, but unable to control their bodies, they charged forward.

Fire Style: Great Fire Annihilation!

Yet, in the icy snow, no one expected that this young woman, Uchiha Hikari, would unleash a terrifying Fire Style jutsu after forming hand seals, stunning everyone.

"Impossible!"

"This level of Fire Style is at least Kage level!"

"What a terrifying Fire Style!"

The gloomy, stormy sky was lit up. Though petite, Hikari unleashed a sea of fire like a tsunami, sweeping across the land.

All the Edo Tensei were within the attack range.

The firelight illuminated her delicate face.

This scene shocked many. Just this Fire Style jutsu alone was enough to prove her strength.

"Impossible!"

Even Obito was stunned by the terrifying fire—he'd never heard of this Uchiha, yet she had such terrifying power.

Water Style: Water Formation Wall!

Water Style: Great Waterfall Jutsu!

Many of the Edo Tensei ninjas had water affinity, so with one Water Style after another, fire and water clashed, creating a violent hissing.

For a moment, steam billowed. To everyone's shock, despite water countering fire, the Fire Style overpowered the Water Style.

The sea of fire swept madly, wave after wave of searing heat, melting the snow instantly.

Even the falling snowflakes turned into raindrops.

At this moment, Hikari's eyes shone with a pair of bewitching Mangekyō Sharingan as she coldly looked at those resisting in the sea of fire:

"No one is allowed to harm Lord Shirou!"

As her Mangekyō spun, the blocked Fire Style suddenly erupted with terrifying black flames.

Dōjutsu: Amaterasu!

In an instant, the already terrifying Fire Style was enhanced by the undying black flames of Amaterasu, instantly overpowering the water jutsu.

"Mangekyō!"

Onoki's eyes bulged as he exclaimed:

"Impossible! How many Mangekyō users does Konoha have?!"

Gaara likewise said gravely: "Amaterasu! This is the same eye technique as Sasuke's and Akatsuki's Itachi!"

The Amaterasu Mangekyō technique's info had long spread throughout the ninja world.

But the users were Uchiha Itachi and Sasuke—they knew this. But who was this never-before-heard Uchiha Hikari?

How did she have the Mangekyō and even Amaterasu!?

On the other side, Obito was shocked to see Amaterasu, instinctively using Kamui to dodge the immortal black flames.

"Impossible!"

What shocked Obito was that there was yet another unknown Mangekyō, and he had no intel on this Uchiha Hikari.

"Edo Tensei bodies are immortal, but Amaterasu is also undying. Let's see which is faster—your regeneration or Amaterasu's burning!"

Hikari's calm voice carried a domineering air, even a hint of Madara's presence.

Then, as Hikari's Mangekyō spun, another technique activated.

Blaze Release: Kagutsuchi!

Suddenly, the sea of fire formed into a giant tornado.

Black Amaterasu flames entwined with red fire, forming a massive, terrifying firestorm dragon that shocked all onlookers.

The Edo Tensei bodies inside screamed in pain.

"Damn! That's Amaterasu!"

"Damn you, Uchiha!"

Hikari's display of dōjutsu even amazed Tsunade.

"It's the same as Sasuke's eye techniques."

She knew about Hikari, but never asked about her dōjutsu—after all, ninja secrets are personal.

But Hikari's outburst of power was truly terrifying.

Seeing Tsunade's shock, Shirou narrowed his eyes and nodded in satisfaction.

"Don't underestimate Hikari. Her dōjutsu and power are far more than this."

Hikari possessed the most diverse dōjutsu—Yasaka Magatama, Tsukuyomi, Kagutsuchi, and Amaterasu.

You could say, in terms of dōjutsu, she was like an upgraded version of both Itachi and Sasuke.

And that's just Mangekyō dōjutsu. In ninjutsu combat, she was very similar to Madara, especially the hairstyle.

You could say, in Hikari you could see echoes of Itachi, Sasuke, and Madara's fighting styles.

"Amazing! But this level of black flames can't burn through my Lightning Release Armor!"

Amid the firestorm, a flash of lightning appeared as the Third Raikage charged out.

Lightning crackled all over him, and clearly, under the Lightning Release Armor, the black flames didn't burn his body.

But as fast as the Third Raikage was, Hikari was faster.

A figure suddenly appeared in front of him, stunning the Third Raikage: "Impossible!"

Hikari had already appeared before him, eyes fierce and cold, shouting:

"Your Lightning Release taijutsu is strong, but that's all!"

With a powerful kick, Hikari's speed matched the Third Raikage's.

With a boom, the Third Raikage was sent flying.

This terrifying power shocked everyone present.

Even Obito was shocked by this style and these words—it reminded him of one person:

Madara Uchiha!

"What's your relationship to Madara?!"

At that moment, Obito could only think of Madara—they must be related, otherwise how could she be so similar?

In his mind, she must be Madara's descendant.

"Could she be Madara's descendant from back then?"

Obito could only think of that possibility, while Hikari was already charging at the Edo Tensei bodies.

With fierce and domineering taijutsu, she coolly drew her Gunbai and sliced through the Seven Ninja Swordsmen.

This made Shirou even more satisfied—Hikari's strength had already reached Madara's level at the Valley of the End.

Both in taijutsu and ninjutsu.

Reaching that level—Madara and Hashirama's—was above the normal Kage level.

With chakra's boost, her taijutsu's explosive power wasn't inferior to the Third Raikage's.

"Damn Uchiha, don't underestimate us!"

Koharu roared in rage, with her Edo Tensei body restored to its peak, plus the hatred of her clan's destruction, her heart was full of resentment toward the Uchiha.

"I was once a legendary ninja alongside Hiruzen..."

Koharu charged with a kunai, only to be met by Hikari's cold gaze—Hikari stomped fiercely on her old face.

The terrifying force and speed silenced her, smashing her body into the muddy ground, her face half-shattered.

Koharu stared up in rage and shock at the Uchiha girl standing over her.

But Hikari never even considered her a threat—this old woman's strength could not touch her at all.

PS: As expected from Boruto character, she's overpowered just because.
