Naruto: Eye System(Rewrite)

(I am gonna restart my Pokemon fanfiction pls check it out.It will be called Pokemon:Ace's adventures.)

Yuto swiftly caught Hitomi before her body could hit the ground. "She must've pushed herself to the limit like Naruko." Yuto muttered, glancing at her closed eyes. He could sense that her chakra reserves were almost depleted, a clear result of awakening her two-tomoe Sharingan and overexerting herself in the battle.

'Naruko and Hitomi are both out now,' he thought, a mix of amusement and exasperation creeping in. 'If Fuu and Kakashi pass out next, I'll officially call myself Taxi No Shinobi 'He chuckled slightly at the mental image of carrying them all back one by one while dressed in a taxi driver suit, though his smile quickly faded as reality set in.

Switching locations with one of his marked kunai, Yuto transported himself to Fuu's home. Gently, he laid Hitomi down next to Naruko, ensuring both were in a comfortable position. The clone he'd left behind earlier gave him a quick nod of acknowledgment before returning its focus to watching over the two unconscious kunoichi.

Yuto didn't linger. He switched back to the battlefield immediately. As he landed, he spotted Fuu still holding her initial jinchuriki form. Her glowing yellow eyes and the silvery sheen on her beetle horn hand radiated power.

Yuto joined her side, already channeling his chakra. "Let's finish this," he said, to which Fuu nodded. The two rushed toward Kakuzu, who was locked in an intense duel with Kakashi.

Kakashi's hands blurred through a series of hand signs before he exhaled a Fire Style: Fireball Jutsu, the roaring flames clashing midair with Kakuzu's Lightning Style: Lightning Bullets Jutsu. The collision resulted in a powerful shockwave, forcing the combatants to steady themselves as fire and lightning crackled in the aftermath.

On the other side, Yuto took a deep breath. 'Radiation Style: Radiation Beam!' he thought, unleashing a piercing, purple-hued energy beam from his mouth. This was the jutsu he got inspiration from a certain purple coloured Godzilla. The beam blazed forward, slicing through Kakuzu's giant thread appendages and disintegrating part of the terrain. Fuu also slamed her Horn hand on the ground. 'Insect style:Horn smash!', she thought as the ground beneath Kakuzu cracked violently, splitting apart and almost swallowing him into a gaping pit.

But Kakuzu wasn't finished. His monstrous form shifted, and with a guttural growl, he exhaled a supercharged Lightning Style: Electromagnetic Murder Jutsu. The sheer power of the attack tore through the battlefield, ripping up stone and soil alike.

"Fall back!" Kakashi commanded, retreating to a safer distance along with Yuto and Fuu. They regrouped as the dust began to settle, their eyes fixed on the towering figure of Kakuzu. His body had now transformed into a grotesque mass of threads, his shape swelling into a giant, twisted form almost five times Kakashi's size. The threads writhed like living tendrils, oozing malice and raw killing intent.

Kakashi exhaled slowly, focusing his chakra as he prepared to unleash a supercharged jutsu. With a firm stance, he channeled a massive amount of energy into his lungs. "Wind Style: Great Breakthrough!" he bellowed, sending a torrential blast of wind hurtling toward Kakuzu.

Yuto quickly joined in, releasing waves of radiation energy that intertwined with Kakashi's wind, creating a volatile storm of purplish-black winds.

Fuu's eyes narrowed, the emerald glow of her chakra flared, and she added her contribution. "Insect Style: Poison Powder Jutsu!" she called out, releasing a shimmering, powdery substance that merged with the already lethal winds. The combination attack became a devastating cyclone of toxic, glowing energy barreling toward Kakuzu.

Kakuzu, however, remained unfazed. His massive form stood firm, his threads shifting unnaturally as he manipulated his chakra. "You'll need more than that," he sneered, sending a massive surge of lightning throughout his body. "Lightning Style: Lightning Disperse Jutsu!"

Lightning erupted from him in all directions, crackling violently and forming a dome of electrified energy. The supercharged lightning expanded outward, neutralizing the incoming attack with an explosive clash of elements. The toxic winds dissipated into harmless particles, leaving only scorched earth in their wake.

Yuto and the others froze in shock, their eyes widening at the sheer scale of Kakuzu's power. 'He's supercharging his attacks now,' Yuto thought grimly. 'With the four masks gone, he's funneling all his chakra into this last one. Every jutsu he uses now is going to be on a whole different level.'

Kakashi's gaze hardened as he glared at Kakuzu. The veteran ninja's mind was racing, he thought back to the unique jutsu of his Sharingan he had used earlier, its toll heavy but its power undeniable. 'I only have one shot at this,' he resolved, his body tense. 'If I fail... the kids won't stand a chance. I know for a fact that Yuto and the girls will surpass me and likely become Kage level in the future, but they are no match for Kakuzu right now. Had I not been fighting against him and distracting him, he would have bombarded the kids with jutsu one after another and killed them.'

He glanced at Yuto and Fuu, his voice steady but carrying the weight of a final gambit. "Stay back. If I fail... run. That's an order."

Yuto's eyes widened in protest. "Kakashi-sensei, what are you planning?!"

But Kakashi ignored him, his Sharingan blazing as it shifted into its Mangekyo form. Chakra surged violently around his eye, and the air around him warped.

Kakuzu's confident smirk faltered as he felt the distortion in space. "What—?!" he began, but his words were cut short.

Reality itself seemed to twist as a giant black vortex appeared around Kakuzu, spiraling with an ominous intensity. The masked ninja's threads thrashed in panic, his body straining against the pull of Kakashi's Kamui.

"No! Not this again!" Kakuzu roared, quickly controlling his threads to anchor himself. The familiar terror of Kamui gripped him; his previous encounter with the technique had scarred him deeply.

But Kakashi poured every ounce of his chakra into the jutsu, his teeth gritting as sweat poured down his face. 'I won't let him escape this time. I'll end it here.' The vortex intensified, ripping into Kakuzu's body.

Kakuzu's threads snapped one by one under the strain. His entire form began disintegrating into the spiraling void. Desperation flashed in his eyes as he made a last-ditch move. With a sickening tear, he detached his head from his body, the final mask still intact behind his head, and used his remaining chakra to break free from his giant body that was sucked inside the Kamui dimension.

Even as his body was consumed, Kakuzu activated a lightning body flicker. A surge of electricity crackled, propelling his head away with blinding speed. He reappeared in the distance, his face twisted in a mix of pain and fear.

For the first time, Kakuzu—the immortal—looked genuinely terrified. Kakashi's unyielding Mangekyo Sharingan death glare burned into his memory.

'Had I not used my thread monster form jutsu earlier, I'd be dead.' The giant thread body gave him enough time to detach his head from the body. His adrenaline surging as he retreated into the shadows. His head raced away, vowing to survive at all costs and to not cross path with the copy ninja again.

Kakashi's knees buckled slightly, his breath labored. His chakra reserves were nearly empty save for some chakra that kept him alive, he was gonna become uncounciois but he held his ground through shear will. He scanned the battlefield, ensuring the threat was truly gone, then he gave a small sigh as his body went limp and he fell in Yuto's arms who shouted his name.
