With One Blade, Overturning Konoha!

Graduation exams were complete.

The genin who passed left the Ninja Academy under the guidance of their teachers. For them, what came next was celebration—and their final moments of farewell.

“Hinata.”

Just as the elite class was preparing to depart, Hakken suddenly walked over from afar, heading straight toward the Byakugan Princess and calling her name.

“Ah… Hakken-sama…”

Startled by the sudden voice, Hinata froze for a moment before quickly bowing. Get full chapters from novel⟡fire.net

“Come with me.”

...

“Are you going to see my father?”

On the way to the Hyūga compound, Hinata asked softly, her cheeks tinged pink.

Walking through Konoha beside a legendary man was a feeling she couldn’t describe, but it made her nerves tighten with every step. And when he mentioned wanting to meet her father, that tension only grew sharper.

Did she perform poorly on stage?

Most likely.

If Hakken hadn’t given her the courage she needed, she probably wouldn’t have been able to display even the most basic form techniques.

“Yeah, I have a few things to talk to him about.”

Hakken sighed as he lightly patted Hinata’s cheek. It was just meeting a parent—did she really need to be this nervous?

And this kind of “meeting the parents” wasn’t the kind she was thinking of.

It was purely to talk.

Thinking back to the words Neji once declared in front of so many people, Hakken couldn’t help feeling reflective.

The Hyūga Clan was divided into the main house and the branch house.

This structure was the primary reason their bloodline remained pure. There was nothing inherently wrong with the system. From the main house’s perspective, the Caged Bird technique—which restrained the branch family and ensured the Byakugan wouldn’t fall into enemy hands—was perfectly reasonable.

But from the branch family's viewpoint, it was unquestionably unfair. That was why someone like Neji existed—someone who tried to fight destiny.

And Hakken had already given Neji his word: he would help him change that fate.

So, notifying Hyūga Hiashi ahead of time was necessary.

When Neji finally proved himself, that would be the day the branch family system was abolished.

And then there was Toneri Ōtsutsuki, whom Hakken had sealed.

In the original story, the Hyūga Clan prided themselves on being Konoha’s strongest clan.

Yet their actual combat strength was far from impressive—so lackluster that they earned the nickname “the background clan.”

For a Byakugan inherited from the Ōtsutsuki Clan, such mediocrity was a pity.

It wasn’t until Hakken obtained the Tenseigan himself that he truly understood the Byakugan’s potential.

Ultimately, the issue lay in bloodline purity.

As shown in the movie, when Hanabi’s eyes were placed on her body, they remained ordinary Byakugan. But when placed on Toneri Ōtsutsuki, they transformed into the Tenseigan.

It became obvious—Toneri Ōtsutsuki functioned as a Byakugan purifier.

Hakken intended to discuss the specifics of this with Hyūga Hiashi.

Strengthening the Hyūga meant strengthening Konoha.

And Hakken’s philosophy differed entirely from the previous Hokage, who favored suppression and political balancing. He allowed freedom to grow—as long as no one attempted rebellion, no one would interfere.

Everything had rules. Follow them, and you were fine.

Because he had the confidence.

No matter how powerful a clan became, it would never surpass Konoha itself.

“Hakken-sama, for you to come without sending word beforehand… not welcoming you personally is truly unforgivable.”

Hyūga Hiashi was clearly shaken.

The younger generation might simply admire this man, but the older generation held deep respect—and a quiet, instinctive fear.

This was an unbelievably powerful man.

A man who had forced all four great ninja villages to bow their heads.

And now, he was widely acknowledged as the leading candidate for the next Hokage.

Why had he suddenly come to the Hyūga Clan?

Could someone from the clan have angered him?

In an instant, Hiashi glanced at Hinata beside Hakken.

Had his daughter caused trouble?

“Don’t misunderstand. I just want to have a proper conversation with you, as the Clan Head of the Hyūga.”

Hakken shook his head and looked at Hiashi.

…

Hyūga Clan Reception Room.

Just like his daughter who had gone to prepare tea, Hyūga Hiashi was feeling noticeably tense. Only he and Hakken remained in the room, yet no matter how he looked at it, the young man before him seemed far more at ease than the host himself.

“Hakken-sama, I…”

After a long, strained silence, Hiashi finally spoke, unable to endure the atmosphere any longer.

“As I thought… I still can’t get used to drinking tea like this.”

Cutting him off, Hakken set down his teacup, lifted his sake gourd, and took a swig.

“Your nerves are worse than your daughter’s.”

He glanced helplessly at the visibly uneasy Hiashi and let out a soft sigh.

“Well, there are two matters.”

Shaking his head, Hakken straightened up slightly and held up two fingers.

“First matter: the Caged Bird seal placed on the branch family, and that outdated system.”

So it really came to this…

Hiashi let out a bitter smile. “I recall Neji sought out Hakken-sama before.”

“Mm. But this isn’t only about him.”

Hakken shook his head. “As an outsider, I technically have no right to interfere with your clan’s internal affairs. But the fact remains—the system is inhumane.”

“The most important point is this.”

Hakken fixed his gaze directly on Hiashi, his expression turning solemn. “I want to ask you one thing: Is the Hyūga Clan… the Hyūga of Konoha?”

Is the Hyūga Clan the Hyūga of Konoha?

Hiashi’s mouth opened, and then he suddenly stood up, bowing deeply with a horrified expression.

“Hakken-sama, the Hyūga Clan’s loyalty to Konoha has never wavered!”

“What could possibly make you say such a thing?”

“Relax.”

Hakken patted his shoulder. “What I mean is, if you truly see the Hyūga as part of Konoha, why must the branch family still protect the main house?”

“Or do you believe Konoha is no longer capable of protecting you?”

Speaking calmly, Hakken continued, “Put simply—while Konoha stands strong, how could the Hyūga bloodline ever be at risk?”

“And don’t you think this system stirs resentment in the branch family? What if one day that resentment erupts? Even if you activate the Caged Bird seal, then what? Slaughter the entire branch family?”

“They’re all members of the same clan. Being treated so differently must feel terrible.”

“For Konoha and for the Hyūga Clan, this is a hidden danger.”

“Abolish the Caged Bird seal, and the branch house will still protect the main house with all their strength. They’ll even feel gratitude and work harder.”

He paused, letting out another sigh as he absentmindedly brushed a hand over his Zanpakutō.

Preaching wasn’t exactly his specialty. He’d said everything he needed to say; whether Hiashi understood depended on him.

But Hakken felt it shouldn’t be difficult. In the original timeline, the Hyūga eventually abolished the system anyway. If Naruto could do it, then he certainly could as well.

“Of course, think carefully about how and when to make the change. Once you’ve personally seen Neji’s resolve, then you can begin implementing it.”

“That’s the first matter.”

Returning to his seat, Hakken took another hearty gulp of sake, shaking his head lightly.

“The second matter concerns the Hyūga Clan’s bloodline.”

Bloodline?

Still unsettled, Hiashi’s heart tightened as he opened his mouth. Internally, he muttered, It’s over.

So he’s finally targeting the Hyūga?

The strict system was the very reason the Hyūga Clan had endured until now. Intermarriage simply did not exist within the clan.

When Hakken mentioned “bloodline,” Hiashi instinctively compared the present Hyūga to the former Senju.

The downfall of the Senju Clan wasn’t just due to war or political suppression. The main cause was intermarriage, which gradually diluted the clan until they were absorbed into Konoha. Tragically, the main Senju line was on the verge of extinction, leaving only Tsunade.

No one else in the village could legitimately bear the Senju name.

Integrating bloodlines into the general population to enhance overall village strength?

This approach…

If the Hyūga Clan were to adopt such a method...

“Hakken-sama, matters of marriage alliances… I cannot make such decisions on my own…”

With a bitter smile, Hiashi spoke in a defeated tone.

But the man before him was Hakken—a person who alone could wipe the Hyūga Clan off the map. Living under Konoha’s roof, Hiashi had no means of resisting.

“Who told you anything about arranging a marriage?”

Hakken frowned, clearly puzzled.

“That is…”

This time it was Hiashi who fell into confusion. And then, all at once, a realization struck him.

Just earlier, Hakken-sama had returned holding his daughter’s hand.

Could it be…?

Recalling all the rumors around Konoha about Konoha’s Kenpachi and his scandalous love life, Hiashi suddenly understood.

The man before him was the only one in the village who had two maids, a legitimate boyfriend, and—according to rumor—even his sister’s best friend harbored feelings for him.

Had he inherited the… enthusiastic… nature of Lord Jiraiya, one of the Sannin?

But if that was the case, then things actually became easier to resolve.

“I see… If Hakken-sama has intentions toward Hinata, then I will immediately consult with the clan elders to choose an auspicious date for her marriage. However, considering Hinata is only twelve, I would ask Hakken-sama to wait two or three years until she is of proper age…”

Marriage?

Getting married?

Outside the door, Hinata—holding a tea tray—was just about to enter when those words reached her ears. Her face erupted in crimson, and she nearly dropped the tray entirely. Regaining her balance, she panicked and retreated in trembling steps.

I’m going to get married…

To Hakken-sama…

Inside the room—

“Stop!”

Hakken was utterly exasperated as he slammed his Zanpakutō onto the table, the impact sharp and heavy.

The meaning was obvious: Keep talking nonsense and I’ll cut you down.

How far did this man’s imagination go?!

Is this what I was talking about?

And going after a twelve-year-old loli? Not happening.

Up to now, the women he had been with—Konan and Kaguya Ōtsutsuki—were all fully mature, powerful women. Even if someone new were to enter the picture, it should be his official girlfriend, Yūgao.

A loli? That required… guidance.

Not interested in Hinata?

Not proposing a marriage alliance?

Hiashi swallowed hard, glancing nervously at the Zanpakutō on the table.

According to his younger brother, Hizashi, Hakken-sama’s blade had already transformed three times.

A kekkei genkai?

A sword-based kekkei genkai? He had never heard of such a thing.

But one thing was certain—he absolutely could not withstand that blade.

Bang.

“Summoning Jutsu.”

With a casual snap of his fingers, a puff of white smoke rose and faded, revealing a struggling, weakened youth on the floor.

“Who is he?”

Pitch-black pupils, strange curled hair, clothing patterned with magatama—

Hiashi observed Toneri Ōtsutsuki with confusion.

“Filthy Earthlings!”

“Trash of inferior bloodlines—I’ll slaughter you all!”

Toneri thrashed violently, screaming with madness. Though blind, he understood one thing—his father, Ōtsutsuki Shiren, was dead.

Boom!

A single punch smashed into Toneri’s face, knocking him unconscious. Hakken calmly sat back down.

“Before anything else, let me explain the origin of the Hyūga Clan.”

The origin of the Hyūga Clan?

Hiashi blinked. As the clan head, did he really need a history lesson?

“A thousand years ago, a naive, air-headed woman brought the God Tree to Earth.”

“She was the progenitor of chakra, but for certain reasons, she was sealed away by her two sons.”

“One of them was Ōtsutsuki Hagoromo, the Sage of Six Paths, who inherited her Rinnegan and the Sage Body.”

“The other was Ōtsutsuki Hamura, who inherited her Byakugan.”

“Hamura eventually settled on the moon with his descendants, guarding the Ten-Tails’ husk, the Demonic Statue of the Outer Path. Hagoromo founded ninshū, bringing unimaginable disaster upon the shinobi world.”

Speaking in one breath, Hakken pointed at Toneri Ōtsutsuki.

“In short, he is the last pureblood on the moon—my compensation to you for abolishing the Caged Bird system.”

He stood, raised his Zanpakutō, and drove it deep into Toneri’s chest.

With Toneri’s agonized screams, the Soul-Devouring Blade ripped away his consciousness.

From today onward, Toneri Ōtsutsuki would be nothing more than a walking corpse.

“H-how… do I even use this…”

Hiashi swallowed again. Today’s shocks were far too overwhelming.

He needed time—lots of it—to digest everything. And more importantly, he still had no idea what this “pureblood battery” was even for.

“Place a Byakugan you deem precious onto him. It will greatly purify and enhance its quality.”

Hakken pulled an ancient scroll from his robe and tossed it before Hiashi.

“This contains the true training methods suited for the Byakugan, including the Eighty Gods Vacuum Attack and other superior techniques…”

Hiashi’s eyes widened as he stared at Hakken.

Those pure white pupils—

That was Byakugan.

And the subtle pressure radiating from them made Hiashi tremble uncontrollably.

A Byakugan purer than his own.

And clearly not transplanted.

“Byakugan - Intimidation.”

Hum.

The crushing pressure froze the entire room, forcing Hiashi down to his knees.

“Never underestimate the Byakugan. That simple Intimidation is only one of its abilities.”

Leaving that final remark behind, Hakken allowed his eyes to revert to normal and turned to leave.

From this day forward, Toneri Ōtsutsuki would serve as the Hyūga Clan’s purification core. With his consciousness erased by Divine Cry, he posed no risk of rebellion.

As for whether someone in the Hyūga Clan could awaken the Tenseigan, Hakken wasn’t sure. In the original story, Hanabi’s Byakugan returned to normal after being removed from Toneri.

But purifying and strengthening the Byakugan—this, he could guarantee.

How far the clan’s potential would rise depended entirely on Hiashi.

As Hakken approached the exit of the Hyūga compound, a figure suddenly appeared before him.

What made him stiffen was her attire.

A kimono of pure white and cherry blossoms…

If he remembered correctly, this was the kimono Hinata wore on her wedding day in the original timeline…

Meeting Hinata’s hopeful, shining gaze, Hakken felt his mind go blank.

This…

What now?
