In the Hokage's office, the Third Hokage was smoking absentmindedly while processing various materials and information.
"I haven't seen Haruto for several days. It seems this ti he was hit a bit hard. He's still too young. Now that he's a ninja, he'll face things far crueler than this. But he's still a child... It's because he's always been so mature that I've treated him like an adult. I should find a chance to visit him and talk."
"Lord Hokage, Haruto requests your presence." An Anbu entered and handed over a scroll sent by Haruto.
After reading the scroll, the Third Hokage was visibly surprised.
"He's surpassed even an S-rank forbidden jutsu? Looks like Haruto is about to surprise again..."
In Haruto's secret laboratory, the Third Hokage finally saw him—but was taken aback by his appearance.The normally neat and tidy Haruto was now standing in front of him disheveled, his body covered in oil and gri.
The Third Hokage frowned—not because of the unpleasant sll, but out of concern. Haruto looked like he hadn't bathed, eaten, or slept in days. His bloodshot eyes revealed how far he'd pushed himself.
"Haruto, are you alright? You've clearly been like this for days. Go get so rest. Whatever this achievent is, it can wait."
Haruto blinked, finally realizing his state—but quickly brushed it aside. He grabbed Third's sleeve and urgently pulled him deeper into the lab.
"This can't wait. With what I've created, Brother Hayate won't have to die. Konoha won't need to lose anything this ti!"
The Third Hokage paused in silence, then replied: "Haruto... Wasn't it already decided? For the good of Konoha, Hayate—"
Before he could finish, Haruto cut in sharply. "Lord Hokage, I told you before—I don't intend to compromise. That's what weak people do. Now I have the power to reject compromise. With this power, the battle situation can be completely overturned."
Seeing the disbelief in Third's eyes, Haruto didn't argue further. He simply led him to the depths of the lab.
There, in the deepest part of the laboratory, Third saw a massive underground chamber—much larger than the last ti. In the center, more than ten of Haruto's shadow clones were transforming sothing with two enormous, strange machines.
"Lord Hokage, before I explain my scientific achievent, let first show you an S-rank ninjutsu I developed."
He handed the Third Hokage a scroll. "I call this technique Kirin."
Without a hint of sha, Haruto took ownership of the jutsu originally created by Sasuke, then explained: "This is a pinnacle lightning-release technique based on Kakashi-sensei's Chidori. It works like this: First, I use Fire Style to heat the surrounding air quickly, creating strong updrafts that form cumulonimbus clouds. These clouds generate natural lightning.Then I shape the lightning into the form of a Kirin and guide it with my Chidori.Because its speed exceeds the speed of sound, it hits in less than a tenth of a second—making it virtually unavoidable.And since it uses natural lightning, chakra cost is minimal while its destructive power is overwhelming.There's almost no jutsu that can defend against it head-on."
The Third Hokage read through the scroll in silence, then comnted:
"Haruto, how long ago did you learn Chidori?"
Haruto blinked, caught off guard. He'd expected technical questions, not this.
"Uh... half a month ago."
Though already well aware of Haruto's talent, Third was once again shaken.
"I have to admit, Haruto—you're a terrifying genius. Developing such an advanced technique from scratch just weeks after learning Chidori... Incredible."
Haruto chuckled modestly.
"You flatter , Lord Hokage. Actually, I had this concept ever since I saw Kurosaki Raiga of the Kiba Blade from Kirigakure harness natural lightning.My civilian-military experints on artificial thunder and rain also laid the groundwork. It's not sothing I just ca up with."
Third nodded in approval.
"Even so, your talent is undeniable. But Haruto... this technique has critical flaws."
"First, you need cumulonimbus clouds. How much Fire Style is that?From my experience, you'd need at least a hundred users casting high-temperature Fire Style.And if you can gather that much firepower, why not just attack directly? Why go through all this trouble?"
Haruto couldn't help but secretly admire Third's insight. He'd grasped the entire chanism at a glance and already spotted key weaknesses.
Yes, Kirin had massive power, and Sasuke never used it again—because it simply wasn't practical.Sasuke had only succeeded that one ti by using Itachi's Amaterasu to generate instant cumulonimbus clouds. And if you already had Amaterasu, you wouldn't need Kirin.
The Third Hokage continued: "Even if you try to speed it up with multiple Fire Style users, the chakra signatures will clash. That makes channeling the lightning precisely extrely difficult.Also, the jutsu is complicated but not hard to interfere with.A few lightning-style users disrupting the charge will render it useless—or worse, backfire.In short, it's only viable in very specific environnts, and only if your opponent has no idea it's coming.And even then, if the cloud buildup is too slow, your enemy can just... leave."
He didn't even finish the sentence. His lack of approval was clear.
Haruto deeply admired how quickly Third had dissected the jutsu. But these flaws were all ones Haruto had already anticipated.
"Don't worry, Lord Hokage. As I said—this technique is just the prototype.The true result of my research is still to co... the real super-S rank forbidden technique I've developed."
Following Haruto Itsuki to the huge building in the open field, the Third Hokage silently examined the core of what Haruto called a super S-class forbidden technique.
In front of them stood two bizarre tower-shaped structures. Massive coils spun slowly around a central spike, and a strange tallic sphere hovered at the top. The Third Hokage studied it for a long ti... but couldn't figure out how it worked.
Haruto, standing beside him, explained calmly: "I call this the Magnetic Storm Coil."
Haruto: "Third Hokage, do you know how cumulonimbus clouds are ford?"
The Third Hokage paused, brows furrowed.
Third Hokage: "I... sowhat understand, but I can't clearly explain it."
Haruto smiled faintly. That answer was expected. In this world, many know what sothing is without knowing why it is. Most people only care about what yields imdiate results. The principles are often ignored, which leads to the unnatural and chaotic growth of technology. Countless inventions exist—without anyone understanding their foundations. This is the age of black technology.
As Haruto caressed the strange machine, he muttered: "I was originally researching how to shift military technology to civilian use. This invention was ant to make artificial rainfall through ninjutsu... but it ended up first being weaponized."
He continued explaining, voice low but passionate: "According to my research, cumulonimbus clouds require three key conditions:
A large amount of unstable energy. The atmosphere must be stratified and unstable. Once stimulated, the energy becos the kinetic force that drives the air upward.
Abundant water vapor. Without sufficient moisture, no tall thunderclouds can form, even with convective energy. That's why these clouds tend to form in humid areas.
A strong impact force. You need enough force to push the air past the free convection level, allowing energy to release and creating a powerful updraft."
Haruto pointed at the coil: This device is simple. Have a lightning-style shinobi release electricity into it. It'll separate the lightning into positive and negative charges, then fire the negatives into the atmosphere via the top sphere. That disrupts the natural atmospheric balance, making it highly unstable and rich in negative charges.If allowed to accumulate unchecked, it could theoretically reach a level capable of destroying the world. Of course, that would require isolating the enormous charge difference...Uncontrolled, this device creates artificial rain. Controlled—it becos the strongest weapon in the world."
The Third Hokage placed a hand on the coil, whispering:
Third Hokage: "...Stronger than any S-rank forbidden technique."
Haruto nodded slightly and shifted to tactics: From what I know, only a handful of Sand and Sound shinobi are inside the village. Most are hiding outside. If you send over 100 lightning-style ninjas, I can eliminate every threat outside. The ones inside? You can handle them, right?"
The Third Hokage was left speechless—not just by the device's power, but by the paradigm shift Haruto represented. In a world where combat was traditionally personal—between individuals or tight squads—Haruto introduced sothing terrifyingly systematic. A technique capable of turning natural disasters into strategic tools.
Third Hokage: "Haruto... Do you realize what you've made? This technique could change the structure of the ninja world... and how battles are fought."
Haruto's expression dimd. "Honestly... I wanted to use this for peace. For agriculture. But this world forced to weaponize it first. I love peace. I hate killing. But I'm also selfish. I want to protect my friends and this village. If they're threatened... I'll beco a demon king if I must.Maybe my path really is to stop killing... by killing. Until... there's peace."
In that mont, Haruto thought of the tragic figures of history—the Third Hokage, the Fourth Hokage, Itachi, Shisui, Jiraiya—sacrificing themselves endlessly for peace that never ca.
"I want to end that. I want to make a world where the next generation doesn't suffer the sa tragedies."
He was silent for a mont, then forced a bright smile.
"Don't worry, old man. I'm just complaining.
This technique isn't as invincible as it sounds. It's slow, needs prep, and depends heavily on environnt. It's defensive at best, not really practical for offense.
Actually... it's just a small part of a bigger idea I call Legion Ninjutsu. Techniques requiring many people. After this battle, I'll probably be known across the ninja world.That's when it's ti—you'll retire, and I'll form my Fifth Hokage Guards."
Haruto's eyes sparkled: "We'll build a massive unit... I've already nad it—The Burning Legion. If anyone opposes my dream... I'll drop a legion-level ninjutsu at their gates and scare them half to death!"
The Third Hokage couldn't tell if Haruto's smile was real or just a mask. Maybe even Haruto himself didn't know. But in the Third's mind, he could already see it—nations forming legions, massive techniques obliterating enemies, the old world of ninja combat gone.
Haruto's inventions could breed ambition. Even the smallest hidden villages might rise to challenge the great powers. Haruto probably saw it too... and feared it.
And yet—
Third Hokage: "Haruto. I believe in you."
Haruto looked up, surprised.
"...Huh?"
Third Hokage: "Even if your creations are misused, you're the one who can set things right.Aren't you?"
For a mont, Haruto stood stunned. Then he smiled again. This ti—it was real.
"Of course. I will beco strong enough to challenge the entire world."
