What if Naruto was Trained by Sosuke Aizen

The Shadow Clone Technique

The Shadow Clone Technique, a B-rank ninjutsu developed by the Second Hokage, Tobirama Senju, was widely known throughout the ninja world. It allowed the user to create physical clones that could perform tasks, gather information, or even fight. However, the technique had a significant drawback: when a clone dispersed, its memories and experiences would return to the original user. This meant that if a clone experienced pain or death, the user would feel it as well.

For Naruto, this technique was a double-edged sword. With the vast reserves of chakra provided by the Nine-Tails, he could create hundreds—or even thousands—of shadow clones to accelerate his training. But the pain and exhaustion from the clones' experiences would also be amplified, potentially overwhelming him.

Naruto had learned about the technique from Sasuke, who had warned him of its dangers. "If you summon too many clones at once, the pain from their experiences could break your mind," Sasuke had said. "You need to be careful."

But Naruto was undeterred. He had a plan.

Kyuubi's Warning

Inside the sealed space, Kyuubi lounged in his gaming chair, his massive form hunched over the computer. Naruto had just explained his intention to learn the Shadow Clone Technique.

"Smelly brat, your mother—" Kyuubi caught himself mid-sentence, remembering the internet slang he'd picked up from his games. "I mean, your hen, the Shadow Clone Technique, is dangerous. The previous Nine-Tails Jinchuriki struggled with it. If you're not careful, you'll end up in agony."

Kyuubi's tone was dismissive, but there was a hint of concern beneath his words. He remembered Kushina, Naruto's mother, who had once attempted the technique without fully understanding its risks. The pain from hundreds of clones dispersing at once had brought her to tears.

"Start small," Kyuubi advised. "Don't create too many clones at once, or you'll regret it."

Naruto nodded, his expression serious. "I understand. I'll be careful."

Kyuubi snorted. "With my chakra, you could create thousands of clones if you wanted. But don't push yourself too hard. I'll teach you the hand seals after I finish this level."

The First Attempt

In the training ground, Naruto stood alone, his hands moving through the familiar hand seals. "Multiple Shadow Clone Technique!"

Bang! Bang! Bang!

A series of explosive sounds echoed through the air as hundreds of Naruto clones appeared in the clearing. Each clone wore the same white robe and had the same determined expression as the original.

"Hi, everyone," Naruto greeted his clones.

"Hello!" the clones responded in unison, their voices booming like thunder.

Naruto smiled, pleased with the result. The technique had worked perfectly. But now came the real test.

"Alright, let's see how this works," Naruto said, turning to one of the clones. "I'm going to dispel you to see how the pain feels."

The clone raised an eyebrow. "Why me? Can't you pick someone else?"

Another clone chimed in, "I'm different. You can't see my true potential."

Naruto sighed. It seemed his clones had inherited his independent streak. "Enough. I need to test this."

With a quick motion, he dispelled one of the clones. A sharp pain shot through his chest, but it was manageable—a dull ache rather than a crippling blow.

"Not bad," Naruto muttered. "But if hundreds of clones were dispelled at once, the pain would be unbearable."

To be safe, he reduced the number of clones to ten. Standing before them, he addressed the group.

"Alright, everyone. Our goal is to get stronger. Without hard work, talent is wasted. To become Hokage, we need power beyond everything. So—"

One of the clones interrupted him. "This motivational speech isn't working for me. I've already seen through the illusions of life."

Another clone smiled warmly. "Naruto, I agree with you. Let's work together for a better tomorrow."

Naruto rubbed his temples. His clones were as stubborn and varied as he was. "Fine. Just don't slack off. Train hard."

The clones scattered, each heading off to practice different techniques. Naruto watched them go, a mix of pride and exasperation on his face.

"Looks like my true personality is more troublesome than I thought," he muttered, picking up his sword, Kyouka Suigetsu, to begin his own training.

The Third Hokage's Observation

In his office, the Third Hokage watched Naruto's training through his crystal ball. A thoughtful expression crossed his face.

"Naruto has learned the Multiple Shadow Clone Technique," Hiruzen murmured. "But how?"

He considered the possibilities. The Uchiha clan was an obvious suspect, but Sasuke had only mentioned the technique in passing. It was unlikely he had taught Naruto the hand seals.

"Could it be the Nine-Tails?" Hiruzen wondered aloud. The idea was surprising but not impossible. If Kyuubi had decided to cooperate with Naruto, it could explain the sudden mastery of such a complex technique.

Hiruzen's eyes narrowed. "This could accelerate Naruto's growth. But he still needs more bonds to keep him grounded."

He made a mental note to assign Naruto to Iruka's class at the ninja school. Iruka, despite his personal hatred for the Nine-Tails, was a kind and compassionate teacher. He could become another guiding light for Naruto.

The Road Ahead

As Naruto continued his training, he felt a sense of satisfaction. The Shadow Clone Technique would allow him to train multiple skills simultaneously, drastically increasing his growth rate. But he knew the road ahead was long and fraught with challenges.

The ninja school awaited, and with it, new opportunities to grow stronger. Naruto was ready to face whatever came his way.
