Naruto: If Sasuke Awakens Entry System

The bloody world seemed endless. Sasuke realized he was trapped in his consciousness space. What was happening?

Suddenly, a black line pierced through, transforming into a massive, pitch-black golem. The monstrous entity towered over the space, connecting the sky and the earth. Its upper body had three heads and eight arms, while its lower body resembled writhing octopus-like tentacles.

With a deafening roar, the golem emitted a black mist that began corroding the bloody space. In mere moments, half of the realm had turned into a dark abyss. Sasuke's eyes widened in shock. The golem was trying to devour his consciousness! If it succeeded, he would become a mindless follower of the evil god, just like Hidan—a puppet, forever forgetting his quest for revenge.

Clenching his fists, Sasuke gritted his teeth. He would never accept such a fate. "I can't die. Not before I avenge Itachi!"

The black mist spread further, consuming three-quarters of the space. At that critical moment, Sasuke's Mangekyō Sharingan flickered to life. A strange red light emanated from his eyes, transforming into Susanoo to resist the golem. The life-and-death battle began, shaking the earth and turning the skies blood-red.

In the real world, White Zetsu observed Sasuke with curiosity. "Why isn't he moving after being hit by the black line?"

Black Zetsu replied, "The black line is likely connected to Sasuke's consciousness space. The entity behind Hidan is probably trying to devour Sasuke's will."

White Zetsu sneered. "Consciousness space? I have a feeling Sasuke won't escape this time."

Jūgo, ignoring the danger, charged toward Hidan in desperation. Before he could reach him, an invisible force threw him back. Crashing to the ground, Jūgo half-knelt, panting heavily. Beside him, Sasuke stood unsteadily, trapped in the internal struggle of his consciousness.

Jūgo's mind raced with memories—being saved by Sasuke, their warm daily moments together. Tears welled in his eyes as he envisioned Sasuke smiling at him, saying, "See you again, Jūgo," before turning away.

Gritting his teeth, Jūgo's face twisted with determination. "Sasuke, I won't let you die. Never!"

Placing his hand on Sasuke's, Jūgo began pouring all his chakra into him, his body trembling as he pushed himself to the brink.

White Zetsu frowned. "Is he trying to save Sasuke?"

Black Zetsu scoffed. "It's useless. Against such a terrifying entity, Sasuke doesn't stand a chance."

Suddenly, Sasuke's Mangekyō Sharingan shed tears of blood. His aura surged explosively.

Black Zetsu gasped, "What? Sasuke's pupil power is rising so rapidly. Such incredible will!"

In the consciousness space, Susanoo was on the verge of collapse, and Sasuke knelt, exhausted. The bloody world around him had almost completely turned black. His ears rang, his breath grew shallow, and his vision blurred.

Was this the end?

"No! No matter what, my determination for revenge will not falter! No one can stop me. Fight, only fight, even if it means destruction!"

Suddenly, a beam of blue light pierced through the darkness. Sasuke blinked in disbelief as the light transformed into Jūgo's ethereal form.

Jūgo smiled and placed his hands on Sasuke's back. "Let's go together, Sasuke."

An immense flow of chakra coursed into Sasuke, reigniting his strength. His heart pounded, and blood boiled with determination.

[Ding! The host surpasses their limits in battle. Mangekyō Sharingan evolves.]

[Mangekyō Sharingan (Gold ★★★☆☆) → Mangekyō Sharingan (Gold ★★★★☆)]

The Mangekyō flared brilliantly, and Sasuke's pupil power multiplied. Rising to his feet, he roared, "This is my last attack! SUSANOO!"

With his words, Susanoo reformed, fully restored. But this time, it didn't stop there—it grew larger, matching the golem's size. Two majestic wings unfurled from its back. This was the complete form of Susanoo!

The golem hesitated for a moment, seemingly surprised by Susanoo's transformation. But Sasuke wasted no time.

"Divine Arrow of Oblivion!"

Susanoo charged forward like divine thunder. The golem bared its fangs, claws slashing wildly. But it was too late.

Boom!

Susanoo's attack pierced through the golem's chest, obliterating it. The golem let out a final wail before shattering into fragments. The consciousness space returned to normal, and Sasuke emerged victorious.

In the real world, the oppressive black clouds dissipated, and sunlight streamed down. Hidan lay pale and motionless on the ground.

Jūgo, trembling, collapsed beside Sasuke.

Black Zetsu muttered, "Impossible... Sasuke defeated the evil god's consciousness? Such willpower is terrifying."

Half a Month Later

At the Ryūnosuke Society base, Karin fussed over Sasuke. "Your eyes have recovered, but don't overuse the Mangekyō. Do you want to go blind?"

Sasuke replied calmly, "I'll be careful. Thank you for everything, Karin."

Karin blushed but huffed. "Don't think this means you can just ignore me! Anyway, don't push yourself so hard again."

"How is Jūgo?" Sasuke asked.

"He's recovering. With my help, he'll be back to normal in a month."

Sasuke nodded, relieved. The battle had been a close call, but the rewards were undeniable.

[Chakra: 320,000 microcal → 400,000 microcal (Super Kage 4th stage).]

[Defeat Kakuzu: Reward—Master of Five Elements merged into God of Five Elements (Gold ★★★★★).]

[Defeat Hidan: Reward—Immortal Evil Power merged into Immortal Seal (Color ★☆☆☆☆).]

The Immortal Seal granted Sasuke the ability to create an Immortal Mark, which protected its bearer from fatal injuries once. However, producing it consumed significant vitality, limiting its use.

Karin rushed into the room with a scroll. "Sasuke, traces of Akatsuki members have been found. They've captured the Sand Village's Jinchūriki."

Sasuke's eyes narrowed. "Was Itachi involved?"

Karin shook her head. "We couldn't confirm. The opponent is too strong for us to approach."

"Tell our people to retreat. I'll handle this myself."

Sasuke's Mangekyō glowed faintly as he turned toward the horizon. "Akatsuki... You're next."
