Jujutsu Kaisen: I am Sasuke Uchiha

Nodding to each other, Naobito and the clan leader readied themselves to attack once more when the unexpected happened.

Resisting the gravity with everything he could pull out, Sasuke simply turned his gaze back to Fugaku, as chakra built up within his left eye. Without hesitation, a trickle of blood flowed down his cheeks as he readied himself...

No one expected or anticipated just what Sasuke could pull off. An inky black cyclone of flames erupted from beneath the feet of the old man, swallowing his figure in an instant, turning him to ash in less than a second, with a searing heat equal to that of the sun, before any of them could react.

Sasuke groggily pulled himself to his feet and shook off the ringing sound in his ears, and the little headache, as his hand clutched his left eye that seemed to be in pain.

Meanwhile, the two surviving gobsmacked elders, Naobito and Asahi, the clan leader snapped out of their reverie as they watched the last of Fugaku's ash drift into the sunset.

*BASTARD!*

They roared in sync. Naobito undid his robes in an instant exposing his muscular upper half as he grabbed a katana and flashed towards Sasuke in a split second. Asahi the clan leader wastes to no time as well and blitzed towards the youth while wrapped in lightning..

The three of them clashed in an epic showdown, two against one. Naobito battled like a madman. Despite his projection sorcery being completely seen through by Sasuke, he still used it to its full potential, jumping in and out of frames erratically, making even Sasuke never lower guard against him.

Asahi on the other hand moved and fought like a thunderbolt, making use of explosive attacks and movements to try to catch the opponent offguard, with his body fully encased in lightning.

Meanwhile, more than a third of the chakra that the system had purchased with 3 million pts had been exhausted by one Amaterasu. Hence it opted for simplicity and efficiency, resorting to only taijutsu to fight off the two old men.

Despite going all out in attack, Naobito and Asahi were barely able to keep up with Sasuke, to even dream of touching him. He was like a snake, slipping out of tight spaces formed by the conjoined attacks, with his incredible agility and fluidity in combat.

Narrowly escaping a slash to the neck from Naobito's blade, Sasuke watched as the elder man jumped into another frame and disappeared, tracing the trajectory of his cursed energy until he got him, trapped him with several metal wires, before a kick sent him skidding a few meters back.

This gave him the much needed room to deal with the pestering old man and his weak lightning cursed technique. Wrapping a kunai in lightning, Sasuke flickered to Asahi and began an all out assault, moving at untold speeds. The kunai in his hand was like a scythe, drawing and harvesting blood from the old man with every slash.

*Clan Head!"

Recovering from the kick, Naobito picked another frame and appeared right in front of Sasuke in a tight spot. Seeing this, Sasuke's eyes squinted and he flipped backwards, landing gracefully. That attack from Naobito had been unexpected even if he caught it coming towards him.

Powering up both eyes this time with his chakra, he stretched out his arm towards the space in front of the two...

Blood trickled down his left eye, followed by an insane attack. An impressive number of inky black flaming spikes erupted from the ground beneath their feet, nearly tearing them apart.

Naobito was quick to switch to a different frame, disappearing from the range of attack, effectively dodging it, but Asahi wasn't so fortunate. One spike pierced into his left arm and he watched his palm burn to ash almost instantly as the heat began eating up his arm.

"Arghh!"

With a loud and painful cry, he empowered his right hand with cursed energy and chopped off the flaming hand, as he watched it combust and burn into cinders almost instantly.

"Die!!"

Naobito rushed over from behind him, jumping into multiple frames hoping to take advantage of Sasuke disorientation to finish him once and for all.

*SLASH!*

His blade successfully ripped into the youth's back as blood spurted out. A wide smile formed on his face which abruptly ceased when he saw the body of the Sasuke he had pierced, morph into crows that flew away while cawing. He turned around, ready to switch frames only to find a pair of demonic Mangekyou Sharingan glaring into his soul as he dropped to his knees in terror.

In the wake of neutralising Naobito and his particularly worrisome technique, Sasuke's figure slowly walked up to the bleeding clan leader with a kunai in hand, ready to put an end to all of this.

"Hahaha. You monster. To think even we are not your match. Perhaps, only that Gojo brat can put a stop to you..." He paused for a moment and staggered to his feet, wiping the blood at the corner of his lips.

"But. I won't go down that easily!" An immense amount of cursed energy began billowing around his figure, forming a cyclone that began to revolve endlessly, amidst crackles and booms of thunder.

"Domain Expansion : Eternal Tempest!"

With a loud roar, and a massive output of cursed energy, both men found themselves in an enclosed domain, resembling a desert, and a bountiful sky filled with dark clouds.

"Hahaha! My cursed technique allows me to summon bolts of natural lightning and incorporate them into my attacks. Summoning too much lightning can harm me in the process, but in here, I am the God of Lightning. I can summon endless amounts of lightning up to any voltage, until the target is completely eradicated!!!"

*CRacK! CrAcK!*

*BOOOOM!*

He monologued with an evil laugh, amidst the booming thunder, yet Sasuke stood still, only lifting his head to glare at the massive bolts of lightning that streaked within the ckouds.

The system was already beginning to experience subtle difficulties in utilizing the remaining chakra which only meant one thing, the five minutes were almost over. His body slowly began heating up as the effects of Kenjaku's poison began to unravel once more.

"Die!*

*BOOOOOM*

The first bolt descended, a massive beam akin to three large palm trees, struck right at Sasuke, decimating the land beneath his feet. Then the second followed, the third, the fourth...

Massive lighting bolts smashed into him continuously for almost 30 seconds, until it ceased.

"Hahaha. No one has ever survived my domain, absolutely no-

What?!!"

Asahi laughed joyously, thinking it was over, after all, his domain was rumoured to be one of the strongest within the clan having a flawless kill record....up until now.

His brows raised in surprise when he saw Sasuke still alive and kicking, yet what shocked him was the purplish avatar that protected the youth. A massive ribcage shielded his figure and a huge arm extended from it, shielding him from the lightning onslaught from above.

Sasuke himself had his head hung low, his breathing erratic, as he bled profusely. Time was running out. His body had already begun feeling the effects of Kenjaku's poison yet it held on, for one last ditch attempt.

He lifted his head, showing a bloodied visage, which scared even Asahi, in conjunction with those demonic eyeballs.

His arm slowly stretched out, as he used the last of the chakra in his possession. His left eye began to bleed, yet he stood his ground and proceeded with his attack.

Amaterasu's Hellish flames burst to life around his body, it's searing heat scalding and corroding the lightning domain before the flames began to fuse into a small inky black orb that revolved around his fingertips.

"I'm not going to let you win!!!!"

Asahi roared out, pouring the last of his cursed energy into his domain as the power of lightning resurfaced once more, ready to tear Sasuke apart.

"Fall!!"

Asahi's roar broke the silent stalemate and both attacks soared towards the targets. A massive draconic shaped lightning bolt blasted towards Sasuke from above, while the Inky black flaming orb shot towards Asahi with a slower pace, as space itself folded under it's immense pressure ...

*BOOOOOOOOM!*

With the domain's cancelling effect, Naobito, who had been sucked into a Hellish genjutsu broke out of it after Sasuke was swept into the domain.

For the first time, tears found their way into his eyes, as he crouched down, shivering and shuddering. Only God knew what exactly Sasuke had put him through. An endless loop where he had to live out his biggest fears and regrets an infinite amount of times would take the soul from every man no matter how strong.

Within his cries, he turned his head to the side, and the moment he saw the domain, his fists tightly clenched and he hoped, deep down that that demon would be torn apart within. However, before his own two eyes, the domain, that was supposed to be nearly indestructible from within was instantly blown apart as a shockwave ripped into the land.

Smoke arose from the explosion, as parts of the domain began to break apart and drift away like ash. From the smoke, a bloodied figure dropped to the ground, staggering to regain his footing, as steam arose from his body.

"Monster.."

Naobito upon seeing the victor emerge from the short battle nearly collapsed to the ground, as he slowly backed up, his eyes widened in fear, as Sasuke's bloodied figure walked closer and closer to him.

He could've fought for his life. Yet he did the only thing his instincts instructed him to do. He powered up his cursed technique, switched frames and disappeared. Yes, the grande second in command of the Zen'in clan ran.

Sasuke on the other hand simply took another step forward and instantly, his body began to convulse and he immediately slumped to the ground, as blood began to pool underneath his body.

*Step*

*Step*

Unbeknownst to the unconscious Sasuke, a figure walked out of a nearby forest with slow and steady steps, gaining towards his position with every passing second..

White hair dyed red with blood, a bleeding nose, and a disheveled figure, yet his sparkly azure eyes glowed with an ever burning flame. He stopped about a meter from Sasuke's unconscious body and glared down in annoyance.

Gojo Satoru, the victor in the battle of the strongest, against his best friend, Suguru Geto now stood victorious before his nemesis. The only regret being that he had not been the one to tear him apart to such an extent.

His eyes glowed for a moment, and he held his fingers out, as cursed energy billowed. A small blue energy sphere slowly coalesced atop his fingers as space itself folded around him like mirrors.

But...

Before he could even launch the attack, a swift figure out of nowhere flashed into the light and grabbed Sasuke's bloodied figure right before Gojo, undetected by the six eyes, until he decided to show himself.

Toji who reappeared several meters away dropped Sasuke onto the ground as he raised a brow, seeing as how his arm turned red from the heat Sasuke's body was giving off, as if he had been boiled alive or something.

"Who are you?!"

Gojo asked in agitation, as he spotted Toji several meters away, his eyes narrowing, expressing his discomfort at how he had only noticed Toji after he had snatched Sasuke right before his own eyes.

"Shush, snowflake. We'll meet pretty soon. You can ask your questions later .." Toji didn't even spare him a glance, as he took out a cloth, wrapped Sasuke within and hoisted him onto his shoulder.

"You would not escape from me again! Sasuke!"

Gojo roared, as he powered up his cursed technique's lapse blue, yet before he could fire, Toji was nowhere to be found and all that was left in the forest was him...
