What if Naruto was Trained by Sosuke Aizen

Life at the ninja school was often uneventful, but Naruto found a sense of routine in its simplicity. Though he occasionally entertained the thought of skipping class, he always reminded himself of the importance of maintaining a good reputation. Every day, he arrived on time, sat through lessons, and participated in training without complaint. His dedication earned him the respect of his peers and teachers alike.

On this particular morning, Naruto entered the classroom as usual and took his seat. Before he could even settle in, Sakura approached him with a shy smile, holding a cup of freshly squeezed orange juice.

"Naruto-kun, drinking juice in the morning is good for your health," she said, her cheeks tinged with pink.

This marked the tenth consecutive day Sakura had brought him a morning drink. Naruto accepted it with a warm smile. "Thank you, Sakura. But you really don't have to go through the trouble. Orange juice isn't cheap, after all."

"It's no trouble at all!" Sakura stammered, waving her hands nervously. "We have plenty of orange juice at home. It's, um, leftover—no, I mean, we have too much, and it would be a waste not to drink it."

Naruto chuckled softly at her flustered explanation. "Alright, thank you then. I appreciate it."

As he sipped the juice, he noticed a pair of eyes watching him from across the room. It was Hinata Hyuga, the girl with short lavender hair and pale white eyes. She quickly looked away, her face turning bright red as steam seemed to rise from her head.

"Good morning, Hinata," Naruto greeted her with his usual gentle smile.

Hinata's response was a barely audible squeak as she buried her face in her hands. Naruto couldn't help but find her reaction endearing. He remembered her from a few years ago when he had helped her during a difficult moment. She had always been kind-hearted but painfully shy. He wondered if she had grown stronger since then.

From what Rock Lee had told him, Hinata was the eldest daughter of the Hyuga clan's main family. Like Sasuke, she was a central figure in her clan, with access to vast resources and training. Naruto had no doubt that her abilities were formidable, even if her demeanor suggested otherwise.

The classroom buzzed with chatter until Iruka-sensei walked in, silencing the room with his presence. "Everyone, today we'll be conducting actual combat exercises," he announced.

The room erupted in excitement. This would be their first official sparring session since starting at the ninja school, and everyone was eager to see how their classmates would perform. Naturally, all eyes turned to Naruto and Sasuke, the two prodigies of their class.

"Combat practice? Perfect. I'll show everyone why I'm the top of our class," Sasuke said with a confident smirk.

Naruto remained calm, his expression unreadable. "Young eagles are fearless because they don't know fear," he replied cryptically.

Sasuke raised an eyebrow. "I've been thinking about that saying for a while now. It doesn't make much sense, you know." He sighed, then his expression turned serious. "Naruto, I'm going all out this time. No holding back. You'd better be ready."

Naruto's smile didn't waver. "I'm looking forward to it. Just don't be disappointed if I don't use Kyoka Suigetsu."

The sparring matches began with two relatively unknown students. Their fight was clumsy and unrefined, a clear indication of their inexperience. Most of the class quickly lost interest, but Naruto watched intently, analyzing their movements and techniques.

"Next up, Hinata Hyuga versus Ten Murakami," Iruka called out.

The atmosphere shifted as the Hyuga clan's name was announced. Naruto leaned forward, curious to see Hinata in action. Sasuke, sitting beside him, offered his commentary.

"The Hyuga clan specializes in gentle fist techniques. Their Byakugan allows them to see the chakra pathways in their opponents' bodies, giving them unparalleled insight. It's a rare and powerful kekkei genkai, though it's nowhere near as versatile as the Sharingan," Sasuke said, his tone dripping with pride.

Naruto glanced at him. "You really think the Sharingan is superior?"

"Of course," Sasuke replied without hesitation. "The Byakugan is limited to insight. The Sharingan can do so much more—copy techniques, cast genjutsu, and even predict movements. The Hyuga clan may be prestigious, but they lack the true power of the Uchiha."

Naruto didn't argue, though he privately believed Sasuke's arrogance might one day be his downfall. Instead, he focused on the match.

Hinata assumed a defensive stance, her Byakugan activating as the veins around her eyes bulged. Her opponent, Ten Murakami, looked nervous but determined. He charged at her with a kunai, but Hinata effortlessly deflected his attacks with precise, fluid movements.

Sasuke frowned. "Is this all the Hyuga clan can do? I could take down an opponent like that in one move."

Naruto shook his head. "You're missing the point. Hinata's using gentle fist techniques to redirect his energy. She's not just defending—she's studying him. This might be her first real combat experience, and she's using it to learn."

As the fight continued, it became clear that Hinata was in complete control. Despite Murakami's efforts, he couldn't land a single hit. Eventually, he collapsed from exhaustion, while Hinata remained calm and composed.

"Not bad," Naruto murmured, impressed. "She's holding back, but her potential is obvious."

Sasuke crossed his arms, clearly unimpressed. "Hmph. The Hyuga clan has some skill, I'll give them that."

The next match was the one everyone had been waiting for. "Uchiha Sasuke versus Uzumaki Naruto," Iruka announced.

The classroom erupted in cheers and whispers. Sasuke stood up, his confidence radiating as he strode into the arena. "Finally, it's our turn, Naruto. Let's see if you can keep up with me."

Naruto followed at a leisurely pace, his demeanor calm and collected. "Arrogance can be a stumbling block, Sasuke. Don't let it trip you up."

Sasuke smirked, drawing a kunai and assuming a fighting stance. "I'll show you the power of the Uchiha clan."

Naruto closed his eyes, a move that confused everyone in the room. Sasuke frowned. "What are you doing? Are you giving up already?"

But before Sasuke could react, Naruto's movements became a blur. He darted forward with incredible speed, his eyes still closed. Sasuke barely had time to block the first strike, but the force of it sent him skidding backward.

The room fell silent as Naruto's true speed and skill were revealed. Even Iruka looked stunned. Sasuke, however, grinned fiercely. "Not bad, Naruto. But I'm just getting started."

The two clashed in a flurry of blows, their movements too fast for most of the class to follow. It was clear that this was no ordinary sparring match—it was a battle between two prodigies, each determined to prove their strength.
