Naruto: Reborn in His Younger Self

---

The return of Orochimaru's hands was undeniably great news for Naruto.

Not only was Orochimaru the greatest scientist and biologist in the ninja world, but he was also an expert in medical ninjutsu and human experimentation.

This was evident in the exceptional skills of his most outstanding student, Kabuto Yakushi.

However, before Naruto embraced the change he had in mind, there were two important people he needed to meet first.

Naruto didn't want them to see him differently—at least, not yet. In this life, for their first impression, he wanted to appear as he originally was.

"Konan, is there any hidden place in Amegakure? Somewhere solid and suitable for training?"

Konan frowned slightly. "You mean a secret training chamber?"

Naruto nodded.

Nagato answered, "Yes. There's an underground chamber beneath the tower in Amegakure. Hanzo built it. It's spacious and well-fortified. I used it when I first developed Pain and trained to control the Rinnegan."

Naruto's lips curled into a smile. "Perfect."

He turned to Orochimaru. "Uncle Snake, I'll need your help. Strengthen the security—set up additional barriers."

Orochimaru narrowed his eyes. "Naruto-kun, are you planning to...?"

A secret underground chamber wasn't enough. He also wanted extra barriers.

This was a clear precaution—because something inside would be too dangerous.

If it was just training, there would be no need for such extreme measures.

What exactly was Naruto trying to suppress?

Orochimaru's mind instantly connected the dots.

The Nine-Tails.

Naruto must have acquired the key to the Eight Trigrams Seal. Otherwise, there was no way he'd be this confident.

Nagato turned to Konan. "Take them to the chamber. I'll remain here in case of any unexpected situations."

Konan nodded.

Naruto glanced at Nagato and grinned. "Thanks, Senpai."

They descended a long underground staircase, finally reaching the hidden chamber.

Konan used her Paper Jutsu, summoning dozens of small paper butterflies. With another hand seal, she ignited them.

Boom! Boom! Boom!

One by one, flames erupted as the paper set fire to the oil-filled braziers lining the chamber walls.

In an instant, the entire chamber was illuminated.

Naruto now saw the full scope of the room.

The underground space resembled an enormous inverted bowl, spanning an area almost as large as a football field.

The ground was laid with polished, ultra-hard marble, each slab perfectly aligned.

Faint traces of battle scars remained—sword marks, burn patterns, and shuriken imprints—a testament to the fierce training conducted here in the past.

The surrounding walls were reinforced with thick, solid granite. According to Konan, they were at least fifty centimeters thick.

Clearly, Hanzo had spared no effort in constructing this place.

Konan turned to Naruto. "This was Hanzo's training ground for his elite forces. It's durable enough to withstand high-level ninjutsu. You can unleash your power without concern."

Naruto surveyed the room before nodding in satisfaction.

He walked to the center of the chamber and faced Orochimaru.

"Uncle Snake, it's time."

Orochimaru smirked, then created three shadow clones. They positioned themselves in a square formation around Naruto.

Hand seals flew in rapid succession.

"Four Purple Flame Formation!"

A blazing purple barrier erupted, sealing the area.

Konan's eyes widened in surprise.

A secret underground chamber. Now, an elite-level barrier as well?

Just what was Naruto planning?

Naruto nodded at Orochimaru, then sat cross-legged, closing his eyes.

Orochimaru narrowed his gaze. Then, he turned to Konan.

"If he loses control and I can't suppress it, go upstairs and bring down all Six Paths of Pain."

Konan's breath hitched. "Is it that serious? Naruto, what exactly are you—"

Orochimaru's voice was grave. "He's about to awaken something more terrifying than the Shinigami."

Inside the Seal – The Mindscape

Naruto's consciousness plunged into the familiar sewer-like realm where the Nine-Tails was sealed.

"Yo, Kurama! How've you been? Miss me?"

He approached the enormous cage with a grin.

Inside, the massive fox lay curled up, one eyelid slightly raised. Upon seeing Naruto, it snorted and shut its eyes again.

"Tch. Don't act so familiar, brat."

Naruto chuckled. "You really need to work on your attitude. Keep this up, and I'll start feeding you dango!"

Kurama's ears twitched, then its eyes snapped open, filled with rage. "You damn humans are all the same!"

Naruto shrugged. "C'mon, no need to get all worked up. I mean, we both know how this ends. Eventually, you'll warm up to me, and we'll be best buddies. Right?"

Kurama's pupils narrowed dangerously.

This was the part it refused to accept.

The future? The idea that he—the mighty Nine-Tails—would ever trust a human? Impossible.

Why should it believe that?

All its life, humans had only ever treated it as a weapon.

Madara Uchiha controlled it. Hashirama Senju sealed it. Uzumaki Mito and Uzumaki Kushina imprisoned it.

The cycle never changed.

Humans didn't seek cooperation—only domination.

Kurama's hatred ran deep, stretching across generations.

And now, this brat had the audacity to act so casual, as if their future partnership was inevitable.

Naruto, however, wasn't here to argue philosophy.

"Well, let's not waste time, Kurama. I came for something important."

With that, he stepped forward and tore off the sealing tag.

Kurama's eyes widened in shock.

"You—!! What do you think you're doing?!"

Naruto smirked.

He raised his left hand. Chakra flared, forming the shape of a key—the key to the Eight Trigrams Seal.

"Isn't it obvious?" His voice was calm. "I'm unlocking the seal."

Then, without hesitation—

He pressed the key against his stomach.

—CLICK.

The moment the lock mechanism clicked, the entire seal began to shift and unravel.

Kurama let out a thunderous roar.

The massive cage shook violently, and with a deafening crash—

The Nine-Tails smashed the gates open!
