Three Realms of No Peace, Solitary Hell Beings

"Nelliel Tu Odelschwanck."

Nelliel said in a low voice, "That is my name, not Miss Antelope."

"Sorry, sorry." Kouya scratched his head and said, "I forgot to introduce myself earlier. My name is Gaoyu Kouun, and this is my Captain, Sosuke Aizen."

Because he already knew the other party's identity from the manga, he almost forgot in reality that he shouldn't have known her name at all.

"Do you want to bring a Hollow into Seireitei? Is it really okay to do something so against discipline in front of the Captain?" Aizen pushed up his glasses.

"Although it's not good to say this, Captain Aizen has also done many forbidden things, so this one won't make much difference."

"You really are..."

"Wait a moment." Nelliel frowned and said, "I never said I was going to Seireitei."

As if! She was a Hollow, and going to Seireitei would be walking into a trap.

Seireitei was different from other places. It had a 'Soul-Concealing Membrane' that enveloped it.

The Soul-Concealing Membrane was a defensive barrier that prevented enemy attacks, and at the same time, it was a 'prison' that prevented internal spiritual bodies from leaving. Even with a Garganta, it would be difficult to move within the Soul-Concealing Membrane.

"Don't you want to understand the 'civilization' of Soul Society?" Kouya said.

In fact, he was reluctant to part with Nelliel's Soul Ability. The ability to change size seemed useless, but it could be very useful in many situations.

For example...

When disguising?

If she transformed into a child, no one would know it was him when he did bad things.

And no one would suspect a child of doing bad things, right?

He really needed such an ability right now.

"I see..." Aizen seemed to have thought of something. He said faintly, "Kouya-kun, let's go back. What you are thinking of will come true in the not-too-distant future."

What?

What did I think of?

I just wanted to gain Nelliel's favor!

Kouya complained inwardly, but he couldn't say it out loud, so he could only sigh.

"Then goodbye, Miss Antelope, no, Nelliel Tu Odelschwanck, in the future..."

"See you in Hueco Mundo."

Aizen opened a Garganta again, and Kouya followed him in.

Before going in, he greeted Nelliel again.

"You'd better not come to Hueco Mundo again."

Nelliel said in a low voice, "Hueco Mundo is not a territory for you Shinigami. If you come again next time, it might not be me you encounter."

"Perhaps everything will be different next time we come," Kouya smiled.

Who says Hueco Mundo isn't the territory of Shinigami?

Perhaps by the next time we come, Shinigami will already be the masters of Hollows.

Kouya returned to Soul Society with Aizen, not Seireitei, but Rukongai.

"Hoo..."

Kouya took a breath. "Although the spiritual particle concentration here is not as high as in Hueco Mundo, the air in Soul Society is indeed fresher."

"At least, there's no aura of slaughter."

"No slaughter... huh." Aizen's glasses reflected the light, and he showed a mysterious smile.

"Kouya-kun, are you interested in becoming a Captain?"

Kouya quickly shook his head.

"No, I don't have that kind of talent. If possible, please let me continue to be a Ninth Seat."

"Gin will become the Captain of the Third Division in a month. I originally intended for you to be the Vice-Captain of the Fifth Division."

"Please spare me. A Ninth Seat suddenly jumping to Vice-Captain will attract attention," Kouya's heart tightened.

This Aizen really thinks I'm some amazing guy, but I'm just pretending. My current strength is at most that of a high-ranking Lieutenant.

"Therefore, you need merit."

Aizen took a step to the side and clapped his hands.

The next moment, a 'Shinigami' walked out of the jungle ahead.

The Shinigami's face was flushed, and he even seemed to have some tentacles on his body. If he weren't wearing a Shinigami uniform and holding a Zanpakuto, no one would have thought he was a Shinigami.

Especially...

The Captain's Haori on him!

"Wow, isn't this a bit too much?"

Gaoyu looked at Aizen. "A captain of the Third Division who's been infected? Captain Aizen, you don't mean you want me to deal with this monster, do you?"

"No, this is a failed product," Aizen said in a low voice. "Because its Reiatsu was too weak, after it parasitized a captain, it was instead counterattacked by the abilities."

"The berserk Spiritual Power rendered him unable to even use his Zanpakuto, so he's useless now."

While Aizen was speaking, the tentacle monster completely ignored him and stared directly at Gaoyu.

Gaoyu's heart tightened. He knew he couldn't appear too flustered, or the mystery he'd put on with Aizen would be completely shattered.

There was no choice. It looked like he'd have to use Shūhei's Black Sun!

"Vice-Captain, huh..."

Gaoyu sighed. "I'm stating this upfront: I won't be handling official duties. You can leave this sort of thing to Captain Aizen."

With that, he drew his Zanpakuto.

"Black Sun."

Gazing at the monster charging towards him, he softly chanted.

The next moment, something incredible happened!

A viscous darkness suddenly appeared behind him, like thick ink!

The darkness slowly spread and rotated, forming a circle, resembling a black sun.

The instant the black sun formed, it released immense heat, especially towards the tentacle monster that had already lunged at Gaoyu!

Boom!

The power of Black Sun erupted instantly. Black flames ignited on the monster's body. The terrifying heat and intense melting caused the monster to immediately let out screams and howls!

"Rooooar!!!"

Metastacia roared. It thrashed violently on the ground, but Gaoyu simply walked up to it and plunged his sword into its brain.

This alone wasn't enough.

Gaoyu thought to himself. While Metastacia had appeared before him, there shouldn't have been only one.

He had seen before that Metastacia could parasitize multiple Shinigami.

If it had gathered all its strength, parasitizing a captain's body shouldn't have resulted in such a berserk state.

Because Gaoyu recalled Metastacia easily merging with Vice-Captain Shiba Kaien.

Even though the gap between a captain and a vice-captain was vast, it shouldn't have directly caused this level of ability backlash.

Furthermore, this Hollow had been modified by Aizen.

Gaoyu looked at Aizen and saw that a faint, almost imperceptible smile was indeed on his face.

Therefore, he didn't withdraw the Zanpakuto plunged into Metastacia's head.

Instead, he softly chanted again:

"May all beings in the three realms find peace and freedom from suffering, may the inhabitants of the solitary hell..."

He had released his Zanpakuto!
