Jujutsu Kaisen: I am Sasuke Uchiha

... Sorry for the late update guys. This week has been rather busy for me. But I'll continue posting on Monday, so no worries.

" No way..."

Sasuke's mouth gaped in surprise, and he unconsciously took a step back, while the eye of the new figure gazed towards him.

"It's been a while...Sasuke.

Come at me with everything. I won't go easy on you.."

The figure spoke and slowly shifted into a stance, while Sasuke clenched his fist and stabilized his beating heart.

Of all the people within Naruto franchise he could battle, why did it have to be him? Why did it have to be the "copy ninja" Kakashi Hatake himself.

Kakashi stood with a hand seal, as his left eye monitored the minute movements from Sasuke's body.

"Let's do this!"

Sasuke clenched his teeth and waved his hand. Immediately, his purplish cursed energy washed over his body, and the white robe he wore transformed into his normal Shinobi garment, consisting of a brown sleeveless brown tank top, purple armguards, blue black pants underneath a purple cloth with a purple rope to tighten the garments at his waist, and finally his Shinobi sandals.

His Kusanagi materialized on his lower back and he took in a deep breath, pooling every single iota of cursed energy for the upcoming battle.

Simply closing his eyes and opening it for a moment, his irises morphed into his three tomoe Sharingan that shone with a never before seen glow, that far eclipsed previous manifestations, and simply glanced towards Kakashi, as a ripple of cursed energy spread.

Without hesitation, both of them formed the hand seal of confrontation and blitzed towards each other at top speed.

Sasuke was wrapped in blue lightning, while Kakashi seemed to flicker in and out of existence like an apparition.

*BANG!*

Their fists clashed in an epic showdown, as a massive wind wave erupted from the epicenter of the collision.

Without hesitation, both of them quickly began exchanging deadly attacks. Punches, kicks, elbow and knee strikes were thrown into the mix, with both fighters gauging each other's strength and trying to take advantage of any weaknesses.

Kakashi hurled a punch towards Sasuke's chin, however the youth quickly reacted, sidestepping to the side and countering with a kick of his own, to which Kakashi blocked. Without giving him much time to recover, Sasuke followed up with a series of timed punches and kicks, each blow precisely thrown less than a second after the former.

Using the OG's knowledge, experience and battle iq as a foundation, Sasuke refined his hand to hand combat to godly levels, to the point where even someone as experienced and well trained as Kakashi had to switch and go on the defensive.

Dodging a punch, a back heel kick and a knee attack to his chin, Kakashi flipped in midair, brought his hands together and performed a couple of seals, before he unleashed an attack.

"Suiton: Suiryudan No Jutsu ---- Water Style: Water Dragon Jutsu!!"

He employed a powerful move right of off the bat, molding his chakra to unleash a gargantuan water dragon that blasted towards Sasuke at immense speeds.

"Katon!: Goryuka no Jutsu! --- Fire Style: Fire Dragon Jutsu!!"

Without wasting time, Sasuke unleashed a similarly powerful move, firing out a technique he had received from the OG's memories.

*BOOOM!*

The two dragons violently smashed into each other, unleashing a massive shockwave that ripped into the land, before, a large smoke screen diffused into the air.

While preparing for a counter, Sasuke's Sharingan quickly picked up movements towards his right. He quickly drew the Kusanagi and intercepted a kunai attack from Kakashi, however, his eyes widened in shock, as he sensed the volatile chakra brewing within Kakashi's body in that moment.

'Its a lightning clone!'

In that moment, Kakashi's body exploded into a myriad of lightning bolts, that instantly engulfed Sasuke's figure and sent him skidding across the land surface into a large river in the distance.

Landing silently onto the river surface, Kakashi stared into his surroundings that had become stark quiet, as he anticipated Sasuke's next moves.

However...

What he failed to realise were the volatile beams of lightning traveling underneath the water, their aura and presence masked underneath the water.

"Ughhh!"

When he noticed the attack, it was almost too late, and the beams of lighting wreaked havoc on his body, however his figure was replaced by a log and reappeared several meters away. While he had managed to evade most of the attack, he had still been struck by several jolts of the current.

Steadying himself atop the churning waves of the water, Kakashi raised his head with a surprised expression and hardened his gaze.

Looking around him for a moment, he quickly pulled out two kunai and crossed them before his chest

*CLANG!!*

In that instant, a figure wrapped in lightning seemed to appear out of nowhere, his blade humming with purple light rapidly slashed towards the neck of the white haired man. A resounding clang caused the waters surrounding their bodies to part.

They separated and blitzed towards each other within a split second, their blades continually clashing in an epic sword battle. Sasuke's sword techniques were unpredictable. Adding that to his nigh godly reflexes and speed made even someone as skilled as Kakashi unable to keep up with him briefly.

Squinting his eye in clear annoyance, Kakashi parried multiple quick slashes from Sasuke's blade, distanced himself a bit and hurled both kunai towards Sasuke's chest.

*BANG!*

Parrying both blades, Sasuke was about to unleash a Jutsu of his own, when Kakashi flickered before him and kicked out. While crossing his arms before his chest dissolved most of the impact, a slight tremor travelled up his bones as the force sent him tumbling in midair.

However...

Having nearly three lifetime of experiences, from Virgil, being a trained undercover CIA personnel, the OG Sasuke's memories and his own training conferred to him experience that was at least close to Kakashi's.

His body in mid air shifted and corkscrewed acrobatically, as he recovered his bearing, even while upside down in the air.

Flicking the Kusanagi outward, he used his right leg to direct the blade's momentum and kicked it out, sending it piercing towards Kakashi's temple.

Kakashi's eyes widened in surprise, however he spin kicked the blade away, and prepared to unleash a big move when Sasuke's figure came gliding towards him with a kick.

Attached to the Kusanagi was a thin metal string with which the youth utilized to pull himself towards the white haired man.

Kakashi was sent tumbling backwards across the surface of the water, but Sasuke gave him no chance to recover and pressed with incredible ferocity.

With no time to recover, Kakashi was quickly subjected to a seemingly endless barrage of punches and kicks. He tried to counter with his own moves, however Sasuke interlocked their fingers and formed one hand seal, as his cursed energy flared.

Seeing what he was about to do, Kakashi kicked out, however, the youth side stepped, dodging it swiftly, before a kick sent Kakashi's head reeling backwards in pain.

Two punches to the ribcage caused the man to bend over slightly in pain, and Sasuke quickly took advantage of this slip up to form the second hand seal he needed, unleashed a side kick to Kakashi's guts, before he hurled himself into the air, using momentum from the kick.

"Katon: Gokakyuu no Jutsu! --- Fire style: Fireball Jutsu!!"

While in mid air, he quickly sucked in his stomach, puffed out his cheeks and unleashed a massive fireball towards Kakashi's figure.

"Suiton: Suijinheki --- Water Style: Water wall Jutsu!"

Kakashi quickly formed a couple of hand seals, as he faced the blazing destruction of the meteor like fireball.

The next moment, the water around him stirred and arose, surrounding his body and shielding him from the onslaught.

*BOOOM!*

The collision of fire and water diffused an incredible amount of smoke into the surroundings, but both fighters recovered, staring towards each other through the smoke.

"I underestimated you, Sasuke. Your taijutsu and kenjutsu are flawless, your Ninjutsu mastery is incredible. You really are the perfect Shinobi, but this ends here...

Kage Bunshin no Jutsu! ---- Multi Shadow Clone Jutsu!"

Kakashi looked relatively unharmed, however the small tears and holes in his Jonin attire, and the various bruises on his body showed that Sasuke had managed to do some damage to him.

Forming a hand seal, two indentical clones materialized behind him. Unlike the normal clone Jutsu which produced a warped clone like version of the Shinobi, the two clones behind Kakashi were the real deal. The Multi Shadow Clone Jutsu was a forbidden technique created by the second Hokage, Tobirama Senju, that created hyper realistic clones of the user with approximately 70 - 80% of the user's strength.

After unleashing the technique, he solemnly pulled up the headband covering his left eye, revealing a three tomoe Sharingan that glared towards Sasuke.

"According to the principle of the technique, two clones behind him means he has only a third of his chakra reserves left."

Sasuke mumbled to himself and took a deep breath. The battle was going to get serious from this point on. He could tell the Kakashi projection wasn't going to go easy on him anymore, due to unleashing the Sharingan in his possession. This had just become a battle to the death.

"Cursed Seal of Heaven!!"

With a burst of purplish black cursed energy, fiery markings materialized on his body, and coalesced into dark black tattoos on the left side of his body. He could feel a profound strength fill his body, as his cursed energy reserves filled up to the brim, and nearly doubled.

However, this wasn't going to be enough to go against the three tomoe Sharingan Kakashi and two shadow clones, and Sasuke knew it.

"If that's the case....

Kuchiyose no Jutsu!! --- Summoning Jutsu!!..

Aoda!! Come out!!"

Forming multiple hand seals, he bit his thumb and allowed the blood to spray out onto the inky black summoning seal before him.

*POOF!*

A large smoke screen diffused into the surrounding, but as it cleared, a rather massive behemoth of a creature, a purplish black Serpent coiled up in the distance.

Atop its head, Sasuke stood with the Kusanagi in reverse, as he glared towards Kakashi and his shadow clones.

"It's been a while, Sasuke-sama. What are your orders?"

A calm raspy voice reverberated as the snake opened it's mouth, but it respectfully acknowledged it's summoner.

"Kill!"

With one word, the snake slithered towards the opponent with incredible speed, but Kakashi and his clones didn't stay idle either and rushed towards the two.
