Konoha.
In an open clearing in the middle of the forest.
Kakashi and Yeruashi's power was at Chuunin level, naturally he couldn't fight in the backyard of the house.
"Are you ready?"
Kakashi gripped the kunai in each hand, his body was slightly leaning forward, with his eyes intently watching Yeruashi's every move, ready for combat.
Yeruashi, for his part, stood in place, with the white light chakra sword in his hands, looking at Kakashi calmly and saying, "Begin!"
Whoosh!!!
The moment Yeruashi's words fell, Kakashi ran towards Yeruashi quickly.
Quickly closing the distance, Kakashi swung his arms sharply, hitting two kunai from both sides at once, Yeruashi swung the short sword diagonally, calmly blocking Kakashi's double attack with one move.
Klang! Klang!
After a brief exchange of blows, Yeruashi's eyes glowed as he launched a strong swing with his sword, destroying the two kunai with force and piercing Kakashi's chest.
Poof!
Kakashi's figure turned into smoke.
Shadow clone!
"Katon: Gōkakyū no Jutsu" ( Jutsu: large fireball).
In the next instant, a voice came from behind Yeruashi, and with the scorching heat approaching, a huge fireball was seen approaching Yeruashi's back.
Yeruashi kept his cool, kicked the ground hard and rushed forward, avoiding a direct collision with the fireball.
Whoosh! whoosh! whoosh! whoosh!!!!
And in the next instant, seven or eight shuriken spun and flew out of the fireball, engulfed in flames, completely blocking Yeruashi's retreat.
"Quite a clever combination of ninjutsu and shuriken."
Yeruashi smiled slightly, and the white light chakra sword in his hand suddenly moved with great speed, leaving a residual image in the air.
Impressively, Yeruashi hit all eight shurikens in the blink of an eye.
Whoosh!
Almost at the same time as Yeruashi repelled the shurikens with his sword, Kakashi's figure emerged from the ground less than a meter behind him, the kunai he held in his hand stabbed into Yeruashi's back and said.
"I win."
A sweat stain poured down Kakashi's forehead and his eyes glistened, for the first time since he and Yeruashi clashed and fought, he had beaten Yeruashi!
However, just at that moment, Yeruashi, who was in front of him, turned his head, smiled weakly at him and said, "You really think so?"
Poof!
Yeruashi's figure took a step back, deliberately crashing into Kakashi's kunai and disappeared in a flash of white smoke.
This scene startled Kakashi, with a look of bewilderment.
Shadow clone?!
"How is this possible..."
Before Kakashi could finish the sentence, there was a sound of air splitting behind him, and he abruptly turned around and raised his hands, reflexively blocking the attack.
A strong kick landed in his hands and Kakashi's figure staggered backwards a few steps before he steadied himself.
"Was that a shadow clone?!"
Kakashi looked at Yeruashi in disbelief.
During the battle, Kakashi carefully watched his brother's every move. How can I use Kage Bunshin no Jutsu without being noticed?!
"No!"
Yeruashi shook his head and said, "That was a normal clone."
Kakashi paused for a moment and sharply exclaimed, "Impossible! Normal clones can't attack, how could he stop my flaming shurikens?"
"The Shurikens were blocked by the main body!"
Yeruashi calmly replied, "Look carefully, I'll show you."
With one hand holding the hilt of the white light chakra sword, Yeruashi's other hand completed the two seals of the Jutsu with one hand and incredibly fast speed, almost in an instant.
Bunshin no Jutsu!
Kawarimi no Jutsu!
"This... "
Kakashi flinched and was silent for a while.
He also often combines cloning and replacement, because these are the most basic and easy to use ninjutsu taught at the Academy, it's not the combination itself that's amazing, but the speed of performing Yeruashi's seals!
And he performed the seals with one hand!
And he could do it even faster than with two hands!
Although Kakashi always knew that Yeruashi is incredibly fast, much faster than him, but this time the speed of performing seals was too outrageous! This is not something a normal person can do!
"...This speed, this is not something a normal human can achieve!"
Kakashi exclaimed in surprise.
Yeruashi wasn't surprised by Kakashi's reaction.
After all, he used a triple acceleration this time, adding the seals with the double acceleration state was still not out of reason, but performing hand seals in a triple acceleration state would be completely abnormal and even a bit creepy from a normal person's perspective!
"... Who knows"
Yeruashi shrugged and said, "Maybe my motor nerves are different than normal..."
Kakashi looked at his brother and rolled his eyes, as if to say "don't take me for a fool", even if his motor nerves are really unusual, it can't be that exaggerated.
"Hmm, you didn't excel in speed before... it started about two years ago and you're constantly getting faster..."
Kakashi fell into a reverie, remembering the past and assessed Yeruashi's speed, saying, "This is too abnormal and already starting to look like a Kekkei Genkai, if you can move even faster..."
Kekkei Genkai!
This word is familiar to all ninja, in the world there is a great variety of Kekkei Genkai, the most common fusion of basic types of chakra, leading to the formation of the elements of explosion, heat, etc. Kekkei Genkai also includes Sharingan, Byakugan and Shikotsumyaku, etc.
Yeruashi's speed is actually slower than Jounin, but the problem is that it seemed unnatural, as if his whole person was in some sort of accelerated state, showing a disconnection with the world.
The only explanation one could think of was a Kekkei Genkai.
The Hatake clan does not have an inheritable Kekkei Genkai, its basis has always been the Hatake kenjutsu, passed down from generation to generation since the Age of the Fighting Kingdoms, but in the world there were cases of Kekkei Genkai awakening, and there were many.
The special state shown by Yeruashi may not be considered a Kekkei Genkai right now, but it can increase the speed much more.... It should be a special Kekkei Genkai!
Yeruashi pondered and said, "Well, it seems like that's the case."
In Naruto's world, there are many different abilities, even something completely perverted like Izanagi, a Kekkei Genkai that allows you to increase speed doesn't seem too unusual.
Kakashi looked at Yeruashi, pondered and said, "If you think so too, then there shouldn't be any mistake, but I don't remember reading about this kind of Kekkei Genkai, nor have I heard of it anywhere..."
Yeruashi stroked his chin and said, "If there is no record, then I should be the first to wake him up, in that case... let's call it, phantom release."
"Phantom?"
Kakashi thought and said, "Very fitting, this incredible speed really looks like a Ghost."
Yeruashi blurted out the first thing that came to his mind, this is nothing more than a simple disguise, if this ability was really a Kekkei Genkai, then it would be worth calling it ... Time Release!
