Seeing this Zanpakuto, Kōga's eyes filled with terrifying killing intent as he looked towards the figure rapidly approaching.

"Yo, long time no see, 3rd Seat Kōga." Stopping about 30 meters in front of Kōga, Ailin waved at Kōga with a smile.

To the others in Soul Society, Kōga was a traitor who started a rebellion. But to Ailin, Kōga was his lucky star. Well, of course the one who made Ailin meet Kōga, Haruko Kuchiki, was even more of Ailin’s lucky star.

Just look, after meeting Kōga for just a few days, all the Zanpakutos of the 13 Court Guard Squad Captains had been completely copied by Ailin.

He just needed to resolve Kōga’s rebellion, then Ailin could take the time to make each of these Zanpakutos. By then, Ailin’s Reiatsu would surely rise again.

Additionally, the experiences of these Zanpakutos' owners would also bring about a qualitative change to Ailin’s Zanjutsu. For bringing all these benefits to himself, Ailin was still very grateful to Kōga in his heart.

"Ailin!" Kōga burned with fury.

It was this person who had ruined everything of his. If not for Ailin's appearance, he, Kōga, would have become Haruko’s husband, the Kuchiki family head in the future, as well as the future 6th Division Captain. But because of Ailin, now he had lost everything.

"Indeed, long time no see."

Although the two had just parted last night, their identities, strengths and beliefs were now worlds apart from yesterday. It felt as if a long time had passed.

"But still, I have to thank you. It was you who made me see the hypocrisy of this world. To thank you, I'll have your Zanpakuto become my power!"

Kōga then pointed his Zanpakuto at Ailin. "Bankai - Mukōjōchū Muramasa!"

Boom!

Tremendous Reiatsu erupted from Kōga as a purple aura spread outwards with him at the center. These past few days, Kōga had reviewed his battle with Ailin over and over in his mind.

He remembered that before Ailin had released his Zanpakuto, his own Muramasa had indeed controlled Ailin's, forcing Ailin to damaging his right hand with Kidō to throw away his Zanpakuto.

This time, Kōga decided to seize Ailin's Zanpakuto right at the start, making it his assistant. Additionally, the materialized Zanpakutos around Kōga also surged at Ailin like a tidal wave. Kōga was preparing to kill Ailin in the fastest speed possible.

Perhaps Ailin's Zanpakuto ability was powerful, but just based on it being immune to Muramasa's control after releasing, that was already enough for Kōga to decide Ailin couldn't be allowed to live.

The narrative has been taken without permission. Report any sightings.

No one liked something beyond their control. Especially when that something's existence was their nemesis.

As the purple aura spread past Ailin's body, the materialized Muramasa had found Ailin's inner world, entering Unlimited Blade Works.

Within Ailin's innate boundary, Muramasa's eyes widened in shock, frightened stiff by everything he saw.

This was the soul space of that Shinigami from just now?

A Shinigami could only have one Zanpakuto right?

So why were there so many Zanpakuto existences here?

And if he wasn't seeing wrongly, behind that Shinigami was... his own figure?

"Welcome, Muramasa. Unfortunately, from the day I awakened this ability, anyone entering this space has to die!" After speaking, Ailin turned and left. At the same time, his voice echoed within this innate boundary.

"Everyone, I know you've been rather bored recently. This guy here is to entertain you! My only requirement is that he can't leave here alive. Everything else is up to you."

......

"Impossible!"

In the outside world, Kōga felt like he had lost his connection with Muramasa.

Muramasa's Bankai invaded the enemy's soul space, using some method to turn the opponent's Zanpakuto against them, stirring up resentment until the Zanpakuto submitted to Muramasa's control. Because time flowed differently in soul spaces, the instigated Zanpakuto would materialize almost immediately in reality after being controlled.

But now, not only was there no materialized Zanpakuto from Ailin, even his own Muramasa hadn't appeared.

"Why is it impossible?"

Ailin opened his eyes, smiling as he asked Kōga, "3rd Seat Kōga, you couldn't even control my Zanpakuto six days ago. Why would you think you can control it now?

Moreover, haven't you considered that I have the absolute strength and confidence to come recapture you alone?"

Ailin's words made Kōga's pupils constrict violently.

The next moment, Kōga's crazed voice yelled out. "All of you, kill him!"

Whoosh!

Over forty Zanpakutos with clear forms and five hundred plus shadowy Zanpakuto silhouettes charged madly at Ailin under Kōga's order.

"Projection—"

Buzz buzz buzz...!

Spiritual power surged as numerous swords materialized overhead, transforming into beams of light that shot down like raging storms at the incoming Zanpakutos.

Boom Boom Boom!

"Ahhhh..."

For a time, explosions and miserable screams sounded continuously. At least over a hundred Zanpakutos died in that volley. Their shadowy forms dissipated as their physical sword forms broke into segments, falling onto the ground.

After that sword rain, a "sword forest" had appeared before Ailin. Beneath the forest were countless shattered Zanpakuto fragments.

"Kill!"

Despite Ailin insta-killing hundreds of materialized Zanpakutos in one move, the remaining ones still swarmed towards Ailin like bees to honey under Kōga's command.

Whoosh—

Ailin's body turned into an afterimage, dashing into the sword forest. He randomly pulled out a Zanpakuto from the ground and moved as quick as lightning, piercing through dozens of Zanpakutos.

Shing Shing!

Blood splattered everywhere. These Zanpakutos fell in bewilderment, not even seeing how they were struck before death.

Whoosh!

Within the crisscrossing shadows, Ailin would pick a new sword from the forest almost every time after killing seven to eight materialized Zanpakutos, continuing his rampage.

Every sword change also brought some adjustment to Ailin's battling style.

Be it as fast as the wind, quick as lightning, mighty as a mountain or violently raging like an inferno...

Any Zanpakuto entering the forest would be slaughtered by Ailin before even reaching a third of the way in!

That's right, this was no longer battle, but outright "slaughter"!
