BLEACH: The Dusk In Red

Sakugo walked down a long dark hallway the seemed to be infinite in height, with the only lighting being the thin purple glow which lined the place. At the very end of that hall way was an immeasurable that was far too heavy for anyone too move.

Once she reached the end, Sakugo could feel it. She was so close.

She rested her hands on the door and activated her fullbring. The entire door glowed with a faint green light before slowly pushing open. As it did she could feel a rush of pressure blow in, but it didn't bother her in the slightest.

There was only one man on the other side of the room. He appeared to be sleeping but the second Sakugo entered, his eyes slowly opened.

He was restrained to the wall with what seemed to be numerous black clothes with several red prongs piercing his chest. His right eye and mouth was covered, but even if you completely blinded him, he'd still know you were there.

Sakugo then used fullbring once again, and removed the seal on his mouth.

"Sōsuke Aizen.", Sakugo called to him

.

"I didn't expect another visitor so soon. Now that you've opened that door, I can feel what's going on outside much more vividly. Don't tell me, you did all of this just for me?"

"No. You were our second objective in coming here, but my father wanted me to make you an offer while we were here."

He chuckled a little from this.

"So instead of coming here himself, he sent his little girl instead? I'm curious, what is it that you have to offer me, that makes you think I'll take your side?"

"For starters, I can free you from those shackles. Fullbring can control your seals, and I can remove the rest of them if you want. If you'll cooperate of course."

"Is that all?"

"You can sense the number of Vasto Lorde outside, right? We have even more of those hidden away on our vessel. If we use your Hogyoku, we can create an army of Arrancar that far surpasses the one you had before. You would be able to "

She presented a very tempting offer. Aizen didn't have many Arrancar at the level of Vasto Lorde in the past, so an entire army that could surpass Soul Societies was interesting to him. Even if he returned to Hueco Mundo, there were very few Arrancar that he thought would come back to serve him. However...

"I refuse. The Arrancar were nothing more than experiments to test the Hogyoku, as well as disposable pawns. As far as I'm concerned with them, they were a failure."

Sakugo was confused by this.

"Is your ego getting in the way of the obvious answer? Your freedom is standing right before you! If you come with us now, we can overthrow the Soul King together!"

She suddenly felt a certain pressure surround her. It made her struggle to breathe as she collapsed to her knees. She tried to stand but fear kept her from looking up. It was not Spiritual Pressure, but Aizen's sheer aura.

 "Together? Who do you think I am? Why would I work together with mere insects as equals? If there was anyone that I would even slightly consider working together, it would be a person whose intellect or strength could even hope to match mine. Neither of which you or this 'father' of yours possess."

"I'M NO INSECT! I'M DESTINED TO BECOME A GOD!"

The second she shouted that, her fear intensified. If she stayed like that any longer, she felt as if she would kill herself from insanity. She quickly sealed Aizen's mouth once more before slamming the doors shut behind.

Once she did, the heavy feeling on her chest had finally disappeared. Even once she left however, he could still hear his voice echo in his mind.

"The one who shall stand atop the heavens, is me."

She angrily stomped away into the darkness.

...

The hole Kai fell into was very deep. He fell for what felt like 5 minutes as he unwillingly travelled to his certain doom. He worried for Yuki as he had left her behind with a powerful enemy, but there was nothing he could do about it now.

"Dammit! I should've learnt how to fly properly!"

As Kai fell, he went past several layers of earth. He eventually realized that these were the different floors of the prison. Eventually he could see the ground as he braced himself for impact.

Instead of feeling the hard ground, he was surprised to be dunked in a large body of water. In fact the entire floor seemed to be made of water. He quickly swam back to the top, while also using his Reiatsu to push him above the water, allowing him to stand as if he were on solid ground.

This was something he learnt as part of his training to learn how to fly.

He looked around only to be met with darkness stretching everywhere he looked.

"Sakugo managed to make a hole all the way down here? She wasn't this powerful the last time I saw her. She must've spent quite a bit of time making this."

In front of him were 5 doors that led to no room. They were all positioned in a way that let them all face a door in which laid face up in the water. Of the original 5 doors, four of them were open while only one was closed.

"I remember seeing, 6 layers while I was falling, so...!"

With some deduction, Kai was able to figure out that he was on the 7th floor of the prison.

And that Muken was just under him. He knew that he was in a great amount of danger, but Sakugo was nearby, so he didn't care.

He approached the doors and noticed that each open door did not obey the conventional laws of physics. They seemed to be connected another space, as its entrance clearly led to a room that did not exist in the same space as Kai.

4 of the doors were open, eluding that 4 of the 5 prisoners had escaped. Yet for some reason Sakugo had left the 5th one down here. Why? Kai simply had to know. If it was important, then it wouldn't hurt to know.

Despite how secure this place was supposed to be, the door easily opened. As it did, Kai immediately prepared to draw his Zanpakutō. But as the door opened he was met with a surprising sight.

The inside of the room was dark with no lighting, the entire inside seemed to made up of only dirt. There were a set of broken chains on the floor, but in the centre was a buff but old looking man.

His build was huge yet he was siting on the floor, meditating. His rough face was hidden behind his long grey hair and beard.

"So another one has come huh. Your lucky the other 4 left before you came, otherwise you would've died on your way here."

Kai had already encountered one of them. If they were all as powerful as he, then Soul Society would have it's hands full for a while.

"So 4 of them really have escaped... You look like you can leave quite easily? Why didn't you go too?"

"Unlike them, I imprisoned myself willingly. I'm serving a sentence for a mistake that I made, so very long ago."

He was understandably confused, but if he wanted to leave all of a sudden then it wasn't like Kai could stop him. Suddenly remembering his objective, Kai turned around to leave. And that was when the doors leading to Muken began to open.

Sakugo who was in a foul mood from her talk with Aizen, immediately noticed Kai.

"What are you doing here?"
