Naruto Gone Insane

"Hehe, little brat, do you think you can challenge me just because you've awakened the Mangekyō Sharingan?"

Kurama's eyes sharpened, like two blades cutting through the air, locking onto Naruto with deadly precision.

Naruto met his gaze fearlessly, a sly grin spreading across his face. "Kurama, you've been controlled by the Mangekyō Sharingan twice before, haven't you?"

"You little brat!"

Kurama's lips twitched, not in amusement, but with a suppressed fury that hinted at the storm brewing beneath. His voice rumbled like distant thunder. "Get in here. I'll tear you apart myself!"

Naruto laughed, stepping forward with confidence. "Alright, Kurama. Show me the strength of the so-called strongest tailed beast."

The rain ceased, and the sky cleared as Naruto made his move, diving headlong into the cage that imprisoned Kurama. After all, this was a sealed space—if he died here, it wouldn't be real.

"ROAR!"

Kurama lunged with a mighty swipe of his claw, the air splitting with its sheer speed. But Naruto sidestepped effortlessly, letting the strike land harmlessly behind him with a resounding crash.

"Shadow Clone Technique!" Naruto clapped his hands, summoning dozens of clones that surrounded Kurama in a semicircle.

"Wind Style: Vacuum Jade!"

The clones inhaled deeply, chakra gathering in their mouths, before unleashing a barrage of Wind Style attacks like machine-gun fire. Kurama shielded himself with his tails, the vacuum bullets colliding with explosive force.

The ground shook, and smoke billowed around Kurama as the attacks left fresh wounds on his tails. Emerging from the smoke, Kurama snarled, his voice dripping with mockery. "Not bad, brat…"

"Wind Style: Rasengan!"

Before Kurama could finish, Naruto's clones charged forward, each wielding a Rasengan. Kurama's heart skipped a beat—no honor in this little brat's tactics.

"Damn it!" Kurama thought, sweeping his tails defensively while bracing for impact.

Suddenly, nine crimson torii gates descended from above, pinning Kurama's tails to the ground.

"What... What is this?!"

"Mingshenmon!"(I just thought it was cool name nothing else) Naruto declared, his grin widening. The sight brought a flash of memory to Kurama—a long-buried humiliation under Hashirama Senju's control.

Stunned for a moment, Kurama hesitated, and Naruto's clones didn't waste the opportunity. They rushed in, smashing their Rasengan into Kurama in a flurry of attacks.

"Bang! Bang! Bang!"

The explosions created another wave of smoke that engulfed Kurama's massive form. But Naruto's Sharingan revealed everything. Though battered, Kurama's fighting spirit burned brighter than ever.

With a roar, Kurama shattered the torii gates and scattered the smoke. "Enough games, brat! You've made me angry!"

Kurama's nine tails rose, surging toward Naruto. But Naruto stood his ground, his hands moving in a calm, practiced motion.

Nine colossal wooden hands erupted from the ground, intercepting the attack.

"Wood Release?" Kurama's voice betrayed his shock.

Naruto smirked, pointing to his left eye. "Not quite. This is my Mangekyō Sharingan ability"

The power of Naruto's left eye allowed him to manifest illusions into reality—a technique that made Kurama's earlier skepticism melt into unease.

"Wood Release: True Thousand Hands!" Naruto clapped his hands again. Trees burst from the ground, spiraling upward to form a massive wooden figure. Though smaller than Hashirama's legendary creation, this Buddha-like construct had nine hands instead of a thousand.

Standing atop its head, Naruto gazed down at Kurama. "What do you think, Kurama? Impressive, isn't it?"

Kurama snarled, memories of his past humiliations swirling in his mind. "Don't underestimate me, kid!"

Gathering his chakra, Kurama began forming a Tailed Beast Bomb. His cheeks bulged as the high-density black energy condensed. With a deafening roar, he unleashed it toward Naruto.

Naruto's face hardened. "Mangekyō Sharingan: Bishamonten!"

The space before him twisted into a massive black vortex, swallowing the Tailed Beast Bomb inch by inch.

Kurama's eyes widened. "This brat's eyes are troublesome…" He began preparing a second Tailed Beast Bomb, unwilling to let up.

But Naruto had his own plan. Shadow clones sprang into action, creating an enormous Rasengan that dwarfed them. The original Naruto retreated to conserve his chakra.

"Kurama, ever heard of a ball falling from the sky?" Naruto's clone shouted as it leapt down with the colossal Rasengan.

Kurama countered with his Tailed Beast Bomb, and the two attacks collided mid-air. The resulting explosion rocked the sealed space, its blinding light consuming everything.

When the dust settled, Naruto stood unharmed at the cage's entrance, his Sharingan spinning. Kurama lay within the ruins, battered but not broken.

"Your right eye… what is it?" Kurama growled.

Naruto smiled, pointing to his right eye. "Bishamonten. It lets me absorb and convert any energy into my own."
