I have been having a very hard time as of late and have decided to channel all of my anger to to creativity, so here's a story about Aizen. Enjoy.

Aizen sat on the floor of his cell, the seals that restrained him still strong. It was dark, pitch black in the bare room, his one uncovered eye closed as he sat. "Eighteen." He said to himself as he sat. "It's been eighteen years since my last visitor Kisuke, what brings you here today?" He asked as the door to his cell opened and in stepped the clog wearing shop keep.

"Funny, I asked myself the same thing as I walked down here." He spoke calmly before dropping a bag to the ground and taking a seat on the floor several feet away from the immortal prisoner. "Maybe I'll figure it out as we play." He shrugged as he opened the bag and pulled out several boxes.

Aizen finally opened his eyes to look at the man in the cell with him. "I'm assuming Shunsui is aware of your presence." He said before looking down at the several games set up in between the two. Chess, Shogi, Go and Connect Four along with a bottle of sake. Once all four games were set up the pair began playing all three simultaneously.

"Probably, else I doubt I'd be here." Kisuke shrugged as he made a move on the chess board while Aizen placed a piece on the Go board.

Nodding Aizen thought over his move for the shogi game before reaching down and grabbing one of the sake cups and pouring himself some. "They often forget to bring me meals down here and only ever bring water, this sake is definitely a welcome change." He chuckled before moving a pawn on the chess board. "You must get bored out there, always being the smartest one around can definitely get tiresome."

"Hm, you're not wrong. It makes finding a chess partner very difficult. Maybe that's why I'm here, to face a challenge." He shook his head before taking a sip of sake. "I'm sure you know, but your sentence was lessened to sixteen thousand years because of your assistance in defeating Yhwach."

"Yes, I was informed. It doesn't really change much." Aizen said casually.

The pair continued taking turns making moves for the various games in relative silence. "If you were free, what would you do?" Kisuke asked out of the blue.

Aizen was quiet as he thought over the question for several minutes. "I'm not sure, with the Soul King gone I find myself without much purpose. My entire life has been dedicated to deposing that... thing." Aizen answered honestly before growing quiet once again. "Maybe I'd take up teaching, I did enjoy the short time I taught at the academy."

"Checkmate." Kisuke said moving his bishop into position to corner Aizen's king.

"Connect four." Aizen retorted with a smirk as he dropped his final chip into the game.

"I truly hate you Aizen, and I never want to see you walk free in this world." Kisuke said before taking a sip of sake. "That being said I respect you, for both your power and mind. Which is why I want to make you an offer."

Aizen raised an eyebrow. "You have my attention."

Reaching into his shirt Kisuke withdrew a metal canister covered entirely with seals and markings. "Inside here is a... key I guess you could say. One that will open a door to a completely separate reality. With it I could free you from here, but you will never return to Soul Society, Hueco Mundo, or the Human world. For all intents and purposes you will be exiled from this plane of existence for the rest of eternity."

Aizen studied the round canister Kisuke held, maintaining a neutral look on his face. "I'm assuming there's no way of knowing anything about the world it would send me to then?"

"Correct, for all I know it could send you to an empty void forever." He nodded.

"And what's stopping me from attempting to recreate this and come back?" Aizen asked grinning slightly.

"The power source for this is a piece of the Soul King's remains." He answered simply earning a nod from Aizen.

"I see." He said as he stared at the object for several minutes. "I'll do it."

Standing Kisuke nodded. "Then I bid you farewell Sosuke Aizen." Twisting the canister a blinding light filled the cell.

Remnant

Ghira Belladonna sat on his porch with a smile as he stared up at the night sky, in his lap laid his young daughter Blake who purred quietly in her sleep as he petted her head. "I thought you two would be out here." He heard the voice of his wife speak from behind him.

Sitting down next to him she rested her head on his shoulder. "She's out like a light, I guess playing at the docks with her friends all day tired her out." He said turning his head and kissing the top of his wife's head.

"It's hard to believe she'll be turning four next month, I'll need to buy some ingredients to bake a... oh my." Kali lost her train of thought at the sight of a bright light high up in the sky. "Is that a meteorite?" She asked squinting her eyes.

Ghira watched as the light grew brighter and brighter before there was a burst and a pair of streaks shot out in separate directions. It took several seconds for the sound to reach them but when it did it sounded like a gunshot, waking Blake up in the process. One of the two streaks flew far off into the distance and over the horizon, the other however seem to be flying directly towards them. Standing Ghira quickly handed his squirming daughter to his wife as he watched the object flying directly over their town before hearing a loud blast sound from beyond the walls. "Kali, take Blake to bed. I have a feeling that wasn't just some meteorite."

Hours Later

Aizen stared up at the shattered moon in the sky from where he laid in the crater he created upon landing, blood was leaking from his mouth and several open wounds across his body. The most painful of which was the large sphere shape chunk of flesh missing from his chest. He wasn't sure how, but some how the process of coming to this world managed to severe his union with the hogyoku, which did explain why he wasn't regenerating. He'd lost his hollow powers because of the split leaving him incapable of healing his wounds rapidly. His spiritual energy seemed to have taken a large hit as well, if he were to gauge it he'd say he was at only around twenty percent of the power he had before, or double the average level of a captain. To top everything off he was completely naked, the only thing that came through with him it seems was the sword clutched in his hand.

"There it is!" He heard a voice shout from not to far away, he didn't really react, he couldn't muster the energy to move.

"What's down there?" Another voice spoke.

"I haven't looked yet chief." The first voice spoke again.

There was a few moments of silence. "By the gods, WE NEED A MEDIC."

That was all Aizen heard before closing his eyes and for the first time in nearly two decades he fell asleep.

Days Later

Aizen's eyes cracked open and quickly he senses were struck by a wave of pain from across his entire body, it wasn't anything he'd not felt before, in fact it wasn't even close to his top five most painful experiences, but it was definitely uncomfortable. The worst pain he'd ever felt was definitely when Kurosaki used his final getsuga, followed closely by Gin's bankai destroying most of his torso.

Forcing himself to sit up he looked around at his surroundings, a simple room with sparse furnishings. Looking down at himself he found that aside from bandages that were tightly wrapped around several parts of his body he was only wearing a pair of boxer shorts he hadn't had before. All of this told him that the inhabitants of this world were both intelligent and generous enough to assist a person in need, not to mention they were able to see him in the first place.

Closing his eyes Aizen extended his senses and searched the area around him for life, hundreds of energy signatures appeared in his mind telling him he was in a town of some sort. Raising his hand he placed it to his chest and began focusing his spiritual energy until a green aura began emanating from his hand. When it came to healing kido he was no Unohana but he was skilled enough to handle injuries of this level with relative ease.

Within fifteen minutes he was recovered enough to get out of bed and move towards the closet against the wall, opening it he smiled at the sight of a traditional grey mens ukata with matching pants. Quickly dressing he looked around the room for the only possession that came to this world with him, unfortunately Kyoka Suigetsu didn't appear to be present.

Sighing Aizen walked over to the door and slid it open stepping out into an empty hallway, deciding to move towards the nearest energy in the home he was in Aizen quickly found himself standing in a kitchen of sorts where a woman wearing mostly black with cat ears on her head stood with her back to him, seemingly preparing tea. "Honey don't forget that Blake has dance class at the neighbors this evening." She said hearing Aizen enter the room obviously mistaking him for someone else, her husband if he were to guess. "Ghira, did you hear- AHH!" She shrieked in surprise as she turned around and found it wasn't her husband behind her, there was a loud crash as she dropped the tray that held to the floor.

Holding up his hands Aizen knelt down and began picking up the shattered glass. "My apologies ma'am, I did not mean to startle you." He spoke in the gentle voice he'd spent decades perfecting, his tone completely devoid of any threat.

Holding her chest the woman slowly calmed herself. "Please, allow me." She said kneeling down as well and also began picking the glass shards. "You're the man my husband found in the desert, the doctor said you wouldn't be up for at least another week so I hadn't expected to see you."

Putting on his best 'I'm harmless' smile he shook his head. "I should have announced myself before entering the room."

"KALI!" A large man shouted bursting into the kitchen. "What's happening?" He demanded looking around, his eyes quickly landing on Aizen.

Bowing his head to the large man Aizen spoke. "Please forgive me. When I woke up I was confused and left the room I was in after dressing myself. When I entered into the kitchen I accidentally startled your daughter here and caused her to drop the tray she was carrying." He knew full well the woman wasn't his daughter but he also knew a little flattery could go a long way, especially when it wasn't obvious that it was indeed just flattery. Manipulating people was an art he was proud to say that he was the undisputed grand master of.

Looking to Kali who blushed slightly as she grabbed the last piece of glass. "Please, it was an accident. Also I'm his wife not his daughter." Her smile was wide as she moved to grab a rag to clean up the tea.

Standing Aizen bowed once again to the large man before him. "I apologize again for worrying you sir. I understand it is you who I have to thank for my rescue and treatment." He said straightening back up.

Noticeably calming down the man nodded. "Yes, I hadn't expected you to awaken so soon, you were in terrible shape when we found you. Please come to my office, I'd like to hear how you ended up falling from the sky completely naked grasping a sword." Clear suspicion filled his voice.

"Of course sir." Nodding Aizen followed the man through the rather large home until they reached an office where the large man gesture towards a chair next to a couch.

"Now, please explained the events that lead to your arrival on Menagerie. It's been nearly twenty years since the last time a human arrived on our shores and it definitely was from the sky." Ghira spoke leaning his head on his fist. Aizen nodded suppressing a smile, that last sentence provided far more information than this man could possibly understand for him. It told him that there were indeed humans in this world and this community were members of a race that consider themselves separate, also based off the fact that no humans had been here in such a long time it told him that the relationship between the two races was strained, however because they had allowed him to live and nursed him back to health it was clear they were not out right hostile to each other.

Aizen was silent for only a moment as he thought over his options. "To be entirely honest sir I'm not sure my self." He gave a fake heavy sigh and placed his face in his hands. "The last thing I remember before waking up in your home was a blinding flash of light followed by pain across my body. I remember my name, swordsmanship, and that I was a traveling teacher. Beyond that I don't know anything." Lying like this was to easy.

The man stared at him for several moments. "You said you were a traveling teacher, may I ask why a teacher would need to practice swordsmanship?"

"For self defense sir, I also believe the way of the sword is great for self discipline." Aizen answered without hesitation, taking a deep breath purely for theatrical reason Aizen straighten himself up. "If I may, I completely understand your suspicion of me. A random armed human falls from the sky and claims not to remember anything, it sounds like the plot to a cliche novel. But I assure you sir that I hold nothing but gratitude to you for helping me in my time of need." Standing from the seat he was in Aizen dropped to his knees and bowed his head to the floor, normally he'd die before doing such a thing but the persona he was going for needed to appear to be as humble as possible. Getting on this mans good side could be the deciding factor as to whether he could peacefully gain access to a source of information on this world and at the moment that was his main goal. "If there is anything that I may do to return your kindness please tell me and if I'm able I will."

Ghira couldn't help but stare at the man prostrating himself before him, for a apparent human to do such a thing before a faunus was all but unheard of. In fact he half expected this man to be out right hostile upon his awakening, but here he was an extremely well mannered and humble man on his knees thanking him. "Please raise your head, there's no need for such things. You were injured in an area normally densely populated by grimm, helping you was the right thing to do. Honestly it's a miracle you weren't found by the grimm before we found you, now that I think about it I don't think we even encountered any of the beasts along the way." The man said scratching his beard. "You said you were a teacher correct? What subjects do you teach usually?"

Taking his spot back in the chair Aizen leaned forward. "I'm very well versed in mathematics, cellular biology, basic sciences, and swordsmanship."

"Hmm." Ghira hummed to himself. "I have an idea... my I just realized I don't even know your name."

Aizen smiled widely. "Sosuke Aizen."

Seven Years Later

Aizen sat behind a desk absent mindedly looking over test papers, it had been seven years since he accepted Ghira's offer to become a teacher for the children of Menagerie and seven years he'd spent learning everything he could about Remnant. To most seven years would feel like a long time to spend simply gathering information, but Sosuke was different. After spending literal decades just sitting and staring at the inside of an empty cell, seven years of teaching children math and science flew by in what felt like days to him.

If he was honest with himself he would admit that he actually very much enjoyed teaching even if the subject matter was as basic as it got. He wasn't in any real rush either, he had no plans or long term goals. He wasn't building an army, or planning a coup, or attempting to slay a god. He had no purpose in this world what so ever and in his seven years he hadn't managed to find one. Instead when he wasn't teaching he spent the majority of his time learning as much as he could.

One topic that fascinated him was Aura. He bought every book and scientific journal on the subject he could get his hands on. Back in the soul society he was, arguably, one of the leading experts when it came to souls. Then he finds himself in a world where human and faunus souls acted so fundamentally different than what he had ever seen before. Semblances also peaked his interest, the idea of a unique manifestation of ones self couldn't help but draw comparisons with the zanpakuto.

"Mr. Aizen, I've finished." A small voice brought him out of his thoughts causing him to look up at the source, an eleven year old Blake stood holding a sheet of paper.

"Thank you Blake." He nodded taking the paper and placing it on a stack of others.

"Um, daddy wants to know if you were still coming over for tea tomorrow." She asked with a blush on her face that greatly reminded him of his former lieutenant.

Smiling warmly at the girl he nodded. "Of course, please tell Chief Belladonna that I'm looking forward to it."

Smiling in return she skipped back to her seat and he returned to grading papers.

Somewhere in Mistral

A young teenage woman with long black hair sat beneath a tree whimpering, in the distance was a large mansion. Her clothing consisted mainly of patch work rags. Her eyes a bright Amber color. Cinder Fall was not having a good day. Her step mother and sister had again been treating her worse than dirt and she'd finally gathered the courage to run away, only now that she had left did she realize she had nothing to her name and nowhere to go.

Picking herself up again she began walking through the thick forest that covered the area, making her way towards the sound of running water in the distance. After crying as much as she had she was thirsty.

Finding the river didn't take long and she quickly dropped to her knees not caring about getting dirty and began taking hand fulls of water. She drank like that for nearly a minute before finally splashing some on her face she stood up and took several deep breaths. Looking around she noticed a large smooth rock and walked over and took a seat on it. "Now what do I do?" She thought to herself.

Out of the corner of her eye she noticed a twinkle that caught her attention, it came from in the water of the river. Tilting her head she stood and slowly stepped into the luckily shallow and slow moving river, she had to suppress a shiver from the cold water. Carefully she moved over to the source of the twinkle and reached down into the water grabbing. Pulling it out she was amazed by what she'd found.

It was a perfectly spherical gem of some type that gave off a bright light blue glow. It was heavier than she'd expected it to be and she couldn't help stare into the swirling energy within it. Something about it made her feel odd, made her feel strong.

This turned out a lot longer than I had expected it. Leave me a review and tell me what you all think. LATER.
