Fate in Bleach: Unlimited Blade Works!

Within the Twelfth Division barracks, Kageroza Inaba was jolted awake by a symphony of alarms.

As he checked the surveillance footage from the World of the Living, his hands transformed into a blur of motion, swiftly silencing the alarms and erasing all records.

On the screen before him, Ailin, clad in golden armor, stood with his arms crossed, his gaze aloof. For a moment, Inaba thought he was looking at a god!

He quickly recognized the other combatant in the battle raging above Karakura Town. It was Sōsuke Aizen, the captain of the Fifth Division, one of the two Mod Souls he had deployed.

However, this "Sōsuke Aizen" was vastly different from the mild-mannered captain in Inaba's memories. Even through the screen, Inaba could sense that this "Aizen" was dozens of times stronger than the original.

But what truly puzzled Inaba was the identity of the armored Ailin. If he wasn't mistaken, it was the Reigai he had created.

Inaba turned on the laboratory lights. Ailin's Reigai floated within a nutrient tank.

His gaze fell upon the Reigai's neck. Three inconspicuous black dots adorned its skin.

Due to Ailin's immense power, Inaba had taken extra precautions while creating his Soul Soldier. He had not only tampered with the "Mod Soul" but had also embedded three high-level Kidō seals within the Reigai, capable of instantly subduing Ailin.

The armored figure in the surveillance footage had the same three black dots on its neck.

In other words, the Ailin in the World of the Living was the same as the unconscious Reigai before him!

But he hadn't implanted the "Soul Candy" pill yet. How could the Reigai have awakened and traveled to the World of the Living?

"The Dangai… The Kōtotsu!"

As this question surfaced, the answer appeared in his mind.

Only the Kōtotsu, the monstrous creatures that dwelled within the Dangai, could send Ailin's Reigai through time.

But why would he send Ailin to the past to eliminate Aizen?

Inaba quickly understood.

Aizen's Mod Soul had betrayed him.

His original plan had been to wait until he had created Reigai of all the Gotei 13 captains before initiating his revolution.

That was why, after discovering the black cat, he had deployed the Mod Souls of Aizen and Isshin Shiba.

But it seemed Aizen's strength had exceeded his expectations.

He had broken free from Inaba's control and had even killed Shiba's Mod Soul.

To prevent Aizen's Reigai from escaping and causing further problems, Inaba had to eliminate it.

He wasted no time. He opened the drawer beneath Ailin's nutrient tank and retrieved a gray Soul Candy pill. He then sent it through a tube, feeding it to the Reigai.

…

Within his Innate Domain, Unlimited Blade Works, Ailin strolled through the forest of swords. He casually drew a blade, used "Analysis" to resonate with it, unlocked its abilities, and tossed it aside.

Every weapon analyzed by Ailin would automatically find its designated location based on its power level. Zanpakutō with seated officer level and above would fly to the sword hill, finding a place to settle.

Those below seated officer level were simply scattered throughout the vast expanse of Unlimited Blade Works.

With each weapon analyzed, Ailin's spiritual pressure, amplified by his Innate Domain, increased slightly.

Suddenly, Ailin paused.

He had sensed someone attempting to connect to his Innate Domain.

Besides himself, who could possibly access this space?

Had someone stolen his spiritual pressure?

There had been instances in the Soul Society where two Shinigami wielded the same Zanpakutō.

According to the Seireitei's research, this occurred when someone learned the name of a Zanpakutō and deliberately interacted with its wielder, allowing their own spiritual pressure to be influenced.

This way, during their "Zanzen" meditation, when they called upon the Zanpakutō's name, they could potentially tap into the original wielder's spiritual pressure, enter the Zanpakutō's soul space, and gain its power.

This typically happened with Zanpakutō that possessed the title of "strongest."

After all, information about these "strongest" Zanpakutō had been passed down through generations.

Whenever a "strongest" Zanpakutō chose a new wielder, that individual would possess unique traits.

For example, Toshiro Hitsugaya, chosen by Hyōrinmaru, the strongest ice-type Zanpakutō, had been able to freeze ordinary people with his spiritual pressure even before he learned its name.

Ailin knew that in the original storyline, Hitsugaya had encountered such a situation.

A boy named Sōjirō Kusaka, drawn to Hitsugaya's unique traits, had managed to connect to Hyōrinmaru's soul space and gain its power.

Sadly, Kusaka's actions had been discovered by the Central 46, who had ordered him to duel Hitsugaya to determine the true wielder of Hyōrinmaru.

Now, Ailin suspected that someone had obtained his spiritual pressure and conducted an experiment, allowing another individual to connect to his Innate Domain.

However, to Ailin's surprise, the one connecting to his Innate Domain was himself.

As Ailin, curious to see who had managed to connect, granted the intruding consciousness access, their minds collided.

In that instant, they gained a clear understanding of each other's existence.

Ailin, within his Innate Domain, then divided all the Zanpakutō into two groups.

The first group consisted of Zanpakutō from the Bleach world. These were off-limits.

The second group comprised weapons he had created based on his memories.

He placed no restrictions on these.

In fact, he hoped these weapons would leave their own mark on this world.

"The Reigai rebellion… To think Ōko Yushima is already preparing at this stage. But it makes sense. If he didn't start now, he wouldn't be able to initiate his plan to replace the Gotei 13 captains so soon after Aizen's betrayal."

"This world is getting more and more interesting!"

Ailin shook his head, dismissing the matter. He had granted his Reigai access to the weapons he had created, allowing it to wreak havoc.

He would let his "other self" provide a grand spectacle for the world!

…

Boom!

A burst of spiritual pressure shattered the nutrient tank, reducing it to dust.

"Is this… the spiritual pressure of the Seireitei's 'Strongest Shinigami'? For a moment, I thought I couldn't breathe."

"No, it wasn't my imagination. Under Captain Ailin's spiritual pressure, I truly couldn't breathe."

As a researcher who had achieved great things, Inaba's attention to detail was impeccable.

Many experiments could be ruined by the slightest error.

"So, you're the one who summoned me?"

Ailin's Reigai opened his eyes and glanced at Inaba, then ignored him.

He approached a nearby nutrient tank and saw his reflection in the glass.

He had flowing black hair, handsome features, and wore a black shihakushō and the captain's haori of the Eleventh Division. He appeared refined and approachable.

But…

Remembering his connection to the Innate Domain, he grasped his clothing.

Rip!

He tore off his shihakushō and haori, their durable fabric offering no resistance.

Refined and approachable? That was his original!

He, the Reigai, was invincible!

Golden spatial ripples appeared beside him, and he drew a Zanpakutō from the void.

"Sun, transform into armor!"

As he uttered the command, the Zanpakutō transformed into a golden light that merged with his body, materializing as a suit of golden armor.

This armor was based on a weapon wielded by a demigod.

Once fused with its wielder, it could reduce the impact of any attack by ninety percent.

In other words, while wearing this armor, Ailin's Reigai would only sustain a tenth of the damage.

Even Head-Captain Yamamoto's Bankai, with its power reduced to a tenth, would only inflict minimal damage.

The golden armor transformed Ailin's Reigai's aura. His gaze became cold and indifferent, as if he held no regard for the world.

Inaba watched, his heart pounding. When Ailin drew his Zanpakutō and released it into the same golden armor he had seen in the surveillance footage, he finally breathed a sigh of relief.

It seemed Captain Ailin's Reigai hadn't lost control.
