Help! I am bound to Aizen!

Hearing Yoruichi's words, Kaelith Yurei was a bit surprised.

According to her, Kisuke Urahara hadn't yet achieved any prominent position within the Second Division, let alone transferred to the Twelfth Division.

In other words, the current Kisuke Urahara was like an untapped asset—much like a rare early investment with limitless potential.

If Kaelith did him a few favors now, he'd gain Urahara's gratitude and a sense of obligation. Then, Kaelith could fully leverage Urahara's talents, pushing him to complete various research projects and inventions that would be of great use.

Kaelith's demands weren't excessive; he simply wanted the technology and video game development in the modern world to advance by two centuries.

With Urahara's capabilities, that shouldn't be too much to ask, right?

Imagining the bright future ahead, Kaelith couldn't help but smile.

Yoruichi noticed Kaelith's expression and gave him a puzzled look.

Kisuke Urahara... From the name, he must be a man. Was he one of those types with such a cute, androgynous look?

Kaelith really did have… broad tastes. A trace of admiration sparked in Yoruichi's heart.

"Sōsuke!"

At the sound of Kaelith's shout, several people in the cafeteria instinctively glanced toward Aizen, who was sitting in the corner.

Aizen sighed, placing a hand on his forehead. He disliked unnecessary attention, and Kaelith seemed to check many of his least favorite boxes.

With a helpless look, Aizen watched as Kaelith sped across half the cafeteria and took a seat beside him.

Seeing Aizen eating alone, Kaelith asked curiously, "Where are Kuchiki Sōjun and Seinosuke Yamada?"

"Kuchiki hasn't been at school all day, so I'm not sure where he went. Yamada Seinosuke is back in the dorms, focusing on his studies. He even asked a friend to bring him his meal."

Hearing this, Kaelith frowned. Sōjun Kuchiki's personality wouldn't allow him to skip class without reason. He'd have to ask Sensei Kinoshita about it later—maybe he knew something.

After getting his meal, Kaelith sat down across from Aizen and began recounting the hand-to-hand techniques he'd learned from Captain-Commander Yamamoto earlier that day.

At first, Aizen listened calmly while eating. But soon, a hint of surprise crossed his face.

"Impressive… As expected of Captain-Commander Yamamoto. His technique seamlessly integrates Spirit Pressure into physical movements, creating explosive power with each strike."

"With these foundational techniques, one could develop moves that, while appearing simple on the surface, could rival even some Kidō spells in power."

Hearing Aizen's analysis, Kaelith's eyes widened. Unlike Kaelith, who was a transmigrator, Aizen had no prior knowledge of Yamamoto's famous Ikkotsu (One Bone) technique. Yet, based solely on the basic training Kaelith described, Aizen had deduced most of its effects.

Was this guy truly a fellow student or some ancient genius reborn?

While Kaelith was astonished, Aizen had already begun considering ways to apply the technique.

After a moment, he asked, "Kaelith, how much of this technique have you mastered?"

Kaelith held his bowl of soup, replying, "I just started today. How much could I possibly know?"

"Perfect, then eat up. When you're done, let's spar and test it out."

The hand-to-hand combat training Kaelith had brought back piqued Aizen's interest.

After their meal, they headed to the dojo, changed into training uniforms, and began practicing Yamamoto's techniques. At first, Aizen struggled a bit, his Spirit Pressure not entirely in sync with his movements.

But within less than half an hour, he began to get the hang of it.

"Ha!"

Aizen took a sudden step forward, fist clenched at his waist, and launched a punch.

Though the motion wasn't particularly fast, Kaelith felt a massive pressure emanating from it, like facing a formidable beast.

He raised his arms, condensing Spirit Pressure into a shield.

Ducking the punch would've been easy, but he was curious to see its effect.

Boom!

The impact nearly made Kaelith's eyes pop out.

At first glance, Aizen's punch seemed ordinary, something any martial artist might execute. But the moment his fist connected with Kaelith's forearm, a terrifying surge of Spirit Pressure burst forth, piercing through Kaelith's shield and penetrating his arm.

If not for Kaelith's deep reserves of Spirit Pressure, this punch might have had him spitting out his dinner.

Aizen looked at his hand, equally surprised by the result.

Yamamoto had only taught Kaelith the basic training method, without explaining its advanced applications.

This punch was something Aizen had devised on his own, using Yamamoto's foundation. He hadn't expected it to be this powerful.

Realizing Kaelith's state, Aizen quickly approached. "Kaelith, are you alright?"

"I'm fine; it's nothing serious," Kaelith replied, flexing his wrist with a wry smile.

He now looked at Aizen as if staring at some kind of monster.

It wasn't the punch's sheer force that shocked him, but the fact that Aizen had managed to trigger a system prompt with that strike.

System notification: Binding detected. Sōsuke Aizen has acquired a new skill—automatically syncing. Sync complete! You've advanced your understanding of hand-to-hand combat and mastered the secret technique Ikkotsu (One Bone).

This abnormal guy had actually managed to replicate Yamamoto Genryūsai's signature move, Ikkotsu, by using basic training and sheer intuition.

Outrageous.

Seeing Kaelith was fine, Aizen sighed in relief.

With a slight smile, he said, "That move just came to me out of nowhere."

"I'll explain the principles behind it, and you can try it yourself."

Kaelith shook his head. "No need. I already understand it."

Aizen blinked in surprise. "Are you sure? That technique goes beyond just a punch and a release of Spirit Pressure."

"How about a test?" Kaelith replied, grinning mischievously.

Aizen felt a foreboding sense of curiosity but couldn't believe Kaelith had grasped the move he'd only just discovered.

He nodded, assuming a defensive stance, signaling Kaelith to attack.

Kaelith chuckled, taking a deep breath.

Unlike Aizen's experimental punch, Kaelith's was executed with full confidence.

Ikkotsu!

Aizen's pupils constricted as Kaelith's fist drew near.

In the next instant, it felt as if a freight truck had hit him head-on, sending him flying back uncontrollably!
