Onepiece: I'm Aizen Sosuke

"As expected of Admiral Zephyr, his aura is truly formidable." Aizen muttered under his breath, tightening his grip on the Zanpakutō resting in his hand.

"Zephyr Admiral? You know that old man?"

The voice came from the wryly smiling figure beside Aizen—**Kizaru**, his relaxed demeanor betraying the fact that Zephyr's oppressive aura hadn't fazed him at all.

Not far from him, **Akainu** stood firm, equally unaffected. Despite their youth, the future Admirals were already demonstrating the traits that would one day make them legends.

Of course, Aizen noted inwardly, Zephyr wasn't unleashing his full might. It wouldn't make sense for the seasoned Admiral to exert himself against mere students.

"It's not acquaintance," Aizen replied smoothly, adjusting his glasses with a calm hand. The faint smile on his face made his response seem almost playful. "I simply know of him."

"He does seem like a nice guy," Kizaru mused, his carefree tone matching his demeanor.

Even Akainu nodded, surprising as that was. "It's rare to meet someone like him. He stands out naturally."

The charisma radiating from Aizen was undeniable. With his composed personality and subtle charm, he seemed to draw people in effortlessly. It was a quiet kind of brilliance—unassuming yet impossible to ignore.

Zephyr's Test

While they conversed, the battle against Zephyr reached its climax. One by one, the students fell to the Admiral's overwhelming strength. Those who managed to endure even a few of his blows were rare exceptions.

When the dust settled, Zephyr's sharp gaze turned to the trio of Aizen, Kizaru, and Akainu.

"Hmph. So, there are some here who can withstand my aura. Looks like not everyone in this batch is all talk," Zephyr thought to himself.

He made no comment aloud, but his subtle smirk spoke volumes.

"It's our turn now," Akainu remarked, glancing at his companions. Though they were strangers at the start, geniuses like them naturally gravitated toward one another. Without needing words, a silent understanding formed between the three.

Suddenly, droplets of molten lava began forming around Akainu, hissing as they touched the ground.

"A Logia user?" Zephyr's eyes gleamed with interest.

Devil Fruits didn't determine strength on their own, but Logia fruits, with their inherent immunity to most physical attacks, were undeniably powerful. And among them, few could match the destructive potential of magma.

Zephyr vs. Akainu

"Drink!" Zephyr roared, his form vanishing in a blur of speed.

Before anyone could react, his Haki-clad fist slammed into Akainu's abdomen, sending him crashing into a wall with a deafening **boom!**

Kizaru's typically calm expression stiffened at the sight. Even with his extraordinary abilities, he hadn't caught Zephyr's movement.

"So fast," Kizaru muttered, his tone uncharacteristically serious.

Aizen, standing calmly nearby, watched with an analytical gaze. "It's only natural. This is Marine Admiral Zephyr. If he struggled against new recruits, it would be laughable."

Kizaru glanced at Aizen curiously. "Are you planning to step in too?"

"Of course," Aizen replied, his tone even. "Opportunities to face an Admiral are rare. It's the best way to understand the peak of this world's power. Only through understanding can we surpass it."

With those words, Aizen stepped forward, releasing an aura so powerful it seemed to ripple through the air.

Aizen's Reiatsu

The gentle sway of his white robes and the calm expression on his face belied the immense pressure emanating from Aizen. It wasn't a random surge of power; it was deliberate and controlled.

"Teacher Zephyr, I look forward to learning from you," Aizen said with a faint smile, his voice carrying a deceptive softness.

Then it came—a wave of **Reiatsu**.

Unlike Conqueror's Haki, this energy was something else entirely. It felt as though it could pierce through the very soul.

Zephyr's eyes narrowed, his perception honed by years of combat instantly recognizing the danger. "What is this...?"

It wasn't just the strength of Aizen's Reiatsu—it was its sheer weight, its overwhelming authority. Even though Aizen had only unlocked a fraction of his power, the pressure was undeniable.

"So, this is Reiatsu," Zephyr thought, his respect for Aizen growing. "This is far beyond anything the others have shown. This kid… he's far more terrifying."

Aizen raised his Zanpakutō, the gentle gleam in his eyes unchanging. "Shall we begin?"

Zephyr tensed, his instincts screaming at him to take this seriously. Against a foe like Aizen, even an Admiral couldn't afford to hold back.
