"Here I come, Kakashi!"
Atop a towering building in Konoha, Guy roared as he charged toward Kakashi, blue lightning crackling through the surging chakra surrounding his body.
Facing Guy after his tremendous transformation and dramatic increase in strength, Kakashi immediately felt an immense sense of pressure. Rather than meeting the attack head-on, he continuously retreated, attempting to evade Guy's relentless assault.
Guy's speed had far exceeded his expectations!
Kakashi's expression changed slightly.
In the blink of an eye, Guy had covered a considerable distance and appeared directly in front of him!
Feeling his scalp tingle, Kakashi had no choice but to raise the short blade in his hand and use offense as defense, slashing toward Guy's descending fist.
If he took that attack head-on, he might actually die!
Fortunately, his strategy worked.
Faced with the terrifying cutting power of the high-frequency vibration blade, even Guy, who possessed absolute confidence in his fists, didn't dare risk having one of them crippled.
Just before their attacks collided, Guy abruptly retracted his fist, tightened his core, and twisted his body. Using the rotational force generated by his waist, he forcibly redirected his attack and avoided contact with the blade.
However, Kakashi had barely managed to evade the punch when a sharp whistling sound suddenly reached his ears.
Having changed the direction of his attack, Guy immediately used the twisting force of his waist to unleash a powerful spinning kick!
"Konoha Whirlwind!"
'Oh no!'
Feeling the cold wind rush past his right cheek and the sharp sting against his skin, Kakashi's pupils instantly contracted.
At this distance, there was no time to dodge!
Just as the attack was about to connect, Kakashi raised his right arm and took the blow with his less vital limb. He then rolled his body sideways, attempting to dissipate as much of the impact as possible.
When he finally came to a stop, Kakashi was half-crouching on the ground, his left hand gripping his right arm, which trembled slightly from the impact.
He stared at Guy standing opposite him, his eyes filled with shock and disbelief.
"Guy, I'm genuinely curious. Did you undergo some kind of genetic mutation? Or perhaps some form of human modification that suddenly made you this strong?"
Kakashi himself had only reached his current level of strength after receiving a bionic eye transplant from Mirai.
But how much time had passed since his previous spar with Guy?
During their last encounter, Guy had barely managed to put up a fight before suffering a miserable defeat. Yet in such a short period, his strength had increased by so much.
If someone told Kakashi that Mirai had selected Guy for some kind of special human modification as well, he wouldn't have doubted it for a moment.
"No modification, actually. If I had to explain it, I'd say I've finally found my own path!"
Guy spoke with deep emotion.
Without Mirai, he might never have discovered this path in his entire life.
The path of Magnetic Field Martial Arts!
It was a path perfectly suited to him, almost as though it had been created specifically for his unique talents!
"So, Kakashi! Let's fight! Let's have a battle of wills, staking all our passion and youth on this contest!"
Guy's eyes burned like raging flames. The blue lightning crackling around his surging chakra seemed to intensify alongside the conviction blazing in his heart.
Unlike Guy, whose entire being radiated fiery passion, Kakashi was filled with helplessness and vexation.
Why did he have to run into Guy again?
All he wanted was to enjoy his Make-Out Paradise in peace!
Unfortunately, no matter how helpless he felt, Kakashi understood that avoiding the battle was no longer an option.
Facing a Guy who was more motivated than ever, there were only two possible outcomes.
Victory or defeat.
Atop the Hokage Building, Mirai watched everything unfolding on the neighbouring rooftop.
In this duel between two different systems, which side would ultimately gain the upper hand?
Clang!
Kakashi launched the first attack.
After their brief exchange, he had already gained a clear understanding of the speed and power behind Guy's attacks.
Once Guy seized the initiative, he would unleash a relentless storm of attacks, leaving Kakashi with little room to breathe!
Kakashi's left bionic eye spun rapidly, calculating the optimal trajectory for his strike.
An attack from this angle had a sixty percent chance of success!
The high-frequency vibration blade reflected a cold glint as it traced a tricky arc, stabbing viciously toward the area beneath Guy's right rib.
The insidious angle of the attack immediately placed Guy under immense pressure.
Rather than retreating, he used offense as defense, punching straight toward Kakashi's face.
Neither man wanted to risk a mutually destructive exchange. In the end, they separated, switched positions, and immediately resumed their assault.
Kakashi pressed the button in the middle of his belt.
A viscous nanite fluid flowed out, spreading across his body. After a brief shimmer, his entire figure disappeared.
"This move again?"
Guy frowned.
He had lost their previous spar because of this very technique.
Back then, Kakashi had used his invisibility to appear behind him without warning, pressing the high-frequency vibration blade against his neck before he could react.
Now, facing an opponent who had once again become completely undetectable, Guy fell silent.
The fiery passion that had filled his expression moments earlier gradually subsided. His breathing steadied, his mind cleared, and his demeanour became as calm as a bowl of still water.
Slowly, he closed his eyes.
The fierce battle suddenly fell into an eerie silence.
From a distance, it appeared as though Guy were standing alone on the rooftop, motionless, with no opponent anywhere nearby.
Suddenly, Guy opened his eyes and threw a punch backward.
THUD!
The sound of flesh colliding rang out.
Kakashi's body reappeared, caught in the middle of an attack. His short blade remained poised to strike, only a few centimeters away from Guy's body, while his eyes widened in shock and disbelief.
'What the hell?!'
His invisibility had been broken?!
"How did you do that?"
Kakashi was utterly perplexed.
The optical invisibility provided by his nanite belt wasn't some crude camouflage technique like the invisibility used by the Iwa ninjas.
It was genuine optical disappearance. The technology eliminated the user's visible presence and suppressed the sound and optical reactions associated with movement, making the user undetectable even through conventional chakra sensing.
So how had Guy discovered his location?!
"Vibrations."
Guy grinned.
"Every time you move, you create faint vibrations in the ground. By sensing those vibrations, I can determine your position!"
'What the heck?!'
'Vibrations?!'
Kakashi stared at him, completely dumbfounded.
"Guy, are you actually human? Or is there some kind of monster hiding beneath your skin? Perhaps a spider or a bat?"
Could a human really perceive vibrations with such precision?
Only Mirai, watching from atop the Hokage Building, understood the principle behind what had just happened.
Bionic abilities were the first stage of the Magnetic Field Martial Arts system.
Through the evolution of his physical body, Guy had acquired hearing comparable to that of a bat, along with a vibrational sense resembling that of a spider.
These enhanced senses allowed him to perceive the subtle disturbances produced by Kakashi's movements and immediately expose his optical invisibility.
"Guy, you're even more troublesome than I imagined."
Kakashi's expression became genuinely serious.
"Next, I'll go all out. If you want to win, then take my strongest move!"
Arcs of lightning crackled around Kakashi's body. Even the high-frequency vibration blade in his hand became enveloped in intense electrical discharges.
Unlike the bioelectricity surrounding Guy's body, the lightning coursing through Kakashi's form was the manifestation of his exceptional mastery of Lightning Style, achieved through the nature transformation of Lightning Style chakra.
"Finally getting serious? Feeling the pressure, huh?! This is the passion of youth!"
Guy's gaze burned with excitement, his fervour growing even more intense.
"Eight Inner Gates! Open!"
The chakra surging around his body suddenly churned violently. Lightning flashed through his hair, a cross-shaped vein bulged on his forehead, and his eyes turned completely white as his gaze became ferocious.
Magnetic Field Martial Arts combined with the Eight Inner Gates!
For the first time, this terrifying combination was about to be revealed on the stage of the shinobi world!
The pressure emanating from the two men collided. The air between them seemed to form two enormous walls that pressed against each other before shattering under the force of their opposing energies.
"Secret Art!Lightning Flash!"
"Magnetic Field Martial Arts!Morning Peacock!"
The strongest attacks belonging to two entirely different systems erupted simultaneously, unleashing terrifying power.
Kakashi's body seemed to transform into lightning itself. Even the short blade in his hand became a streak of lightning, its outline almost indistinguishable from the electrical currents surrounding it.
Guy leaped into the sky, his fists striking so rapidly that they left countless afterimages. The friction generated by his punches heated the surrounding air, creating a fiery assault that resembled the magnificent display of a peacock spreading its feathers.
The original Morning Peacock was an attack associated with the Sixth Gate of the Eight Inner Gates. By combining it with Magnetic Field Martial Arts, Guy had transformed it into a unique technique of his own.
Lightning and fire!
Technology and martial arts!
At that moment, two entirely different systems unleashed their strongest forms against each other!
The rooftop was torn apart by the aftermath of their collision. The destructive force spread outward, and numerous villagers throughout Konoha, many of whom had been busy with their daily work, looked up in shock at the top of the building.
"Oh my god! What's happening?!"
"Are enemies attacking the village?!"
The rooftop had transformed into a sea of lightning and fire.
The building began to collapse beneath the tremendous force of the attacks, while nearby villagers fled in panic as the destructive energy spread through the surrounding area.
If the clash wasn't stopped soon, the entire building would collapse. The surrounding structures within a hundred meters would likely be destroyed as well!
Unfortunately, Kakashi and Guy, standing at the very center of the confrontation, had a bitter problem of their own.
Having committed themselves to an all-out attack, neither man could stop.
The outcome of their clash had already slipped beyond their control.
The fact that they had managed to maintain the current situation was itself the result of an unspoken restraint on both sides. If there were even a slight imbalance in their power, the terrifying energy accumulating between their attacks would collapse like a breached dam, releasing its full destructive force in a violent eruption.
"Oh no!"
Just as Kakashi was beginning to regret ever engaging Guy in this battle, a crisp cracking sound suddenly rang out from the high-frequency vibration blade in his hand.
Crack!
The energy accumulated during their clash seemed to have found an outlet.
With terrifying speed, the unstable force swept outward!
Kakashi's expression changed drastically.
'It's over!'
Their own injuries might be manageable.
But the villagers nearby would be caught in the ensuing explosion!
Below them, the villagers stared in horror as the raging energy erupted from the rooftop. The entire ground began to tremble beneath the pressure.
Just as Kakashi was about to despair—
Snap!
A crisp snapping sound suddenly rang out.
The raging, out-of-control energy abruptly solidified.
To the astonishment of both Kakashi and Guy, the violent force began retreating as though it had suddenly become docile. It contracted into a tiny point, hovering harmlessly between them.
"Kakashi, I believe I told you that arrogance is the greatest enemy of a genius."
Kakashi stared blankly at Mirai, unable to comprehend what he was witnessing.
Mirai had appeared beside them and pinched the tiny point of energy created by their combined full-power attacks between his index finger and thumb.
With a gentle flick, the energy emitted another crisp cracking sound before dissolving into countless specks of starlight.
Kakashi was utterly dumbfounded.
Beside him, Guy was equally frozen in place.
A crisis that had threatened to unleash almost the entirety of their combined destructive power had been resolved with such ridiculous ease that neither man could fully believe what had happened.
If not for the enormous circular depression in the ground, they might have wondered whether the entire incident had been nothing more than a dream.
"External aids can make you stronger in a short period, but you must also devote yourself to training."
Mirai's tone carried a clear note of admonishment as he addressed Kakashi.
Kakashi's face had turned pale as he stared at the broken high-frequency vibration blade in his right hand.
During the clash, the energy released by their attacks had exceeded the blade's structural limits. The weapon he had always regarded as his strongest had now been completely destroyed.
"Don't forget, you still owe me a favour!"
Mirai's sudden reminder caused Kakashi's expression to stiffen.
He immediately remembered the agreement he had made when Mirai offered to modify his body.
The bionic eye transplant had come with a condition: Kakashi would have to complete one task for Mirai, a task he absolutely could not refuse.
And now, he still had no idea what that task would be!
If Mirai asked him to do something strange, or even something indecent, he would still be obligated to fulfill his promise.
At that moment, no matter how much he regretted his decision, Kakashi had no choice but to accept reality.
Every gift bestowed by destiny already carried a price.
Kakashi understood that principle all too well.
This was the price he had to pay for obtaining power.
"The Research Department has developed the latest high-frequency vibration blade. I've already reserved one for you. It's considerably stronger than the one you were using."
"I understand."
Kakashi gave a complicated reply, but deep down, he couldn't help feeling that Mirai's foresight was unfathomable.
Had Mirai already anticipated that his weapon would be destroyed during this battle?
His earlier complacency had vanished completely, replaced by a powerful sense of urgency.
Strictly speaking, he had lost this battle.
Guy's strength had far exceeded his expectations.
If Kakashi continued to slack off like this, he would eventually be surpassed by Guy completely.
That was something he absolutely could not accept!
Seeing the change in Kakashi's demeanour, Mirai knew his actions had achieved the desired effect.
After all, Kakashi was the disciple of his older brother, Minato. Given that relationship, Mirai naturally wanted to see him continue growing stronger.
Minato had always been protective of the people he cared about. If he learned from the afterlife that his student spent his days immersed in Jiraiya's romance novels, he would probably be quite frustrated that he hadn't taught Kakashi better when he was alive!
Of Minato's original team of three, Kakashi was the only one who remained.
Mirai still cared deeply about his older brother's last surviving student.
After admonishing Kakashi, Mirai turned his attention to Guy.
"Guy, well done! Your talent in Magnetic Field Martial Arts is far beyond that of ordinary people!"
"Ahhh!!! Hokage-sama praised me! This is the passion of youth!!!"
Guy immediately dropped to his knees, looked up at the sky, and burst into tears of excitement.
The exaggerated display made both Mirai and Kakashi's mouths twitch.
It seemed that after entering the Magnetic Field system, Guy's personality had become even more flamboyant than before.
Mirai was about to say something else when he suddenly sensed something and turned his head toward the distant sky.
The unusual movement immediately caught Kakashi's attention.
He followed Mirai's gaze.
"What's that...?"
Kakashi frowned.
'A bird?'
More precisely, it appeared to be a homing pigeon, the kind specially bred to carry messages between ninja villages.
With his keen observational abilities, Kakashi recognized the bird's purpose at a glance.
But there was a problem.
Konoha didn't keep homing pigeons of this kind.
That meant the bird belonged to another ninja village.
Why would one be flying toward Konoha?
While Kakashi was still puzzling over the situation, Mirai raised his hand.
A terrifying force of attraction erupted, pulling the homing pigeon out of the sky and straight into his grasp.
As expected, a message tube was tied to the pigeon's left leg.
Mirai removed the letter and glanced through its contents. His brows furrowed slightly.
Standing behind him, Kakashi leaned forward curiously to read the message.
The moment his eyes fell on the contents, his pupils contracted.
"This is...!"
Sunagakure was under attack?
The target was a Tailed Beast?
And they were requesting Konoha's assistance?!
A barrage of information flooded Kakashi's mind, leaving him momentarily frozen in place.
