Dislcaimer: I do not own Bleach.

A/N: For those who are confused, this is a story about Aizen who is Ichigo's brother. There is another Aizen in this universe who is a captain and is doing very bad things. Aizen Kurosaki has just followed Ichigo into Soul Society, a few hours after Ichigo went in. Aizen got 'trained' by Urahara who knows more than he is letting on.

KKKKKK

It has very lonely in the room all by herself and all Rukia's been doing was thinking, thinking about her pasts, her regrets. All the insignificant and significant issues and choices she has ever done. Her life before becoming a shinigami, her life after and her life now and the terrible mess she was in.

As she rethought her life and everything, her thoughts went back to a certain orange haired boy. Ichigo Kurosaki was a pain in the ass, a powerful fighter, and most of all an idiot to the bone. But he was such a lovable idiot.

She hoped he was safe at home with his family. In the quiet and stark plainness of her cell, Rukia counted the hours and days. She started thinking about Chad, Ishida, Inoue and Ichigo. She thought about Ichigo's family, the crazy father and the two younger sisters. The elder brother who she never meet but once, not that it counted for he never saw her.

She wandered if he would've liked her, if all of the Kurosaki family was crazy or if he could see ghosts too. She saw pictures of the older boy. In comparison to Ichigo, he was always smiling not scowling or blank faced. The eldest sibling of the Kurosaki house and the one whom Rukia had almost no knowledge about.

In fact…

Rukia tilted her head up gaze at the ceiling. She didn't even know his name except that the girls of the family calls him Ai-ni. During their time together, Ichigo didn't really talk much about his older brother. It wasn't that Ichigo didin't want to, it was just the issue was never brought up. It was the just the sheer amount of hollow attacks, school and the meeting/confrontation of all the other people just pushed the issue into the back of her mind.

She did see a picture before. It was a Halloween picture of the group from a few years back. Ichigo was absolutely cute back then, his fuzzy orange hair covered by a police man's cap. Even then he had a perpetual frown and furrowed eyebrows. Yes, she was not ashamed to say she squeed at the picture.

Next to him was a taller brown haired boy with red-brown eyes. He too was dressed in a police officer's outfit. Ichigo had to explain to her that he was wearing contacts and that his brother was near sighted and without contacts or glasses he was a blind as a bat. A cute bat but a really blind one. One who is prone into walking into walls.

Ichigo also readily told her about the tattoo incident. How Isshin blew a gasket for ten straight minutes before laughing for the following twenty. Ichigo was snickering as he told her recalling the look on his older brother's face and how comical it was.

The only other thing she knew was that he goes to a different high school than Ichigo and was off on an exchange program/summer school. That meant there was one less person to hide Ichigo's powers from, one less person to involve in this mistake.

During her time here, she accepted her execution. She accepted the orders from the central 46 no matter how inane they were. It was times like these that she remembered that Soul Society was flawed. That bad things happen to good people and that Gin Ichimaru was a scary ass person. But there was nothing to be done. Even her adopted brother didn't plead her case. No one helped her. So all she could do is think.

Acceptance.

It was the least she could do for dishonoring the Kuchiki name and shaming her brother who took her in.

As her last act she will right the wrong.

Be well Ichigo she thought silently. He would be safe in the Living World. He would live, age and then die. He will become a shinigami properly. He won't remember her but at least he will live to his full potential. Even if she die, she will die happy and content.

KKKKKKKKK

Aizen ran through the Dangai, his small legs making it harder to get through the tunnel than if he was at his normal size. But alas, his shinigami self looked only eleven or twelve and barely topped four feet. He wore the standard shinigami garb but was a pint sized person compared to his real body.

It wasn't his fault he was tiny as a kid an only got a growth spurt when he got older. But when he first became a shinigami, he was small. His soul self would remain that size due to his lack of maturity. At the very thought Aizen rolled his eyes. He was lots mature, heck he was more mature than Urahara who wore that ridiculous hat.

If the heart believes itself to be young then the soul is young. Aizen didn't like the thought of that due to his inner child, he would be this small. He wanted to be big. His sword was as big as he was, and that wasn't fair. At least it was sealed. When he first became a shinigami, his spiritual energy was strong and he had to learn how to control it. That was his first lesson. By learning how to seal his soul cutter and by wearing reiatsu suppressors, Aizen was able to keep under the radar.

He did not want shinigami coming and killing him or taking him away. Soul Society is very touchy of ryoka and of humans learning the existance of shinigami. Besides it wasn't as if Urahara taught him much. Urahara stated to him that his zanpakuto was not meant to teach others in ways of shikai or bankai. So Urahara taught him other things.

Control.

Control.

Control.

If there was anything Urahara drilled into his head was control. Power was nothing if you can't direct it at will. So that was what he did, he learned control. He learned sword fighting by taking kendo classes and sometimes some fencing. From there he learned a variety of martial arts, karate, and judo.

He even learned stuff from Star Wars. Some movies had really good stunt doubles.

There was a lot of things he did to supplement what Urahara didn't teach him. He dabbled in Jujutsu, Taekwondo and some Boxing. Most of this was done on his own time, in-between the school work and helping out at the clinic. Most of it was self taught, through books and practicing it with the daily fights with Isshin. He wasn't an expert at any of those but he could recognize most exaggerated movements and defend himself. Unlike Ichigo he didn't focus on karate and as such in a straight out fight with Ichigo using karate he would lose. Ichigo was one of the better fighters in Karate.

But in a straight out brawl he would win. Even without using his illusions, he could maybe get in a tie with Ichigo in a fight. Ichigo had freakily impressive stamina. It wasn't athletic stamina, it was the kind you would expect out of a very fit twenty year old man, not something in a teenager. It was the kind you see in American marines who run for twenty miles up a mountain with sixth pound packs on during one hundred degree temperature.

Aizen was a mixed martial artist. He liked, for once, to be unpredictable. This way, he can switch from form to form, gaining the element of surprise. He knows various grappling moves, submissions, kicking, punching, using his elbows and knees. He also knows how to use the environment to his benfit and he wasn't above throwing dirt into a person's eye. Aizen actually thought he knew enough to beat Urahara only to get his ass handed to him by Yourichi. She then proceeded to tell him all his mistakes and proceded to beat him up the entire week. In the end, he learned more from her than he did from Urahara for physical combat. He also had a nice collection of bruises from that week.

In all six years, the only thing he learned was shinigami history, kido spells, shunpo-even that was self learned-and control. He lost count in the sheer amount of times he was used as a guinea pig in his experiments and the times he was dropped into the training area against some unknown thing and expected to survive it. Urahara was a sneaky bastard and conniving too. Very manipulative too.

Just the thought of Ichigo meeting Urahara made him worry. At times, Ichigo can be very gullible and easy manipulate, he should know, he himself manipulated Ichigo multiple times. Aizen hoped that whatever trouble was occurring, Ichigo would be able to keep himself alive and in one piece.

In this small, miniature shape, he would be able to sneak by people unseen. If that doesn't work, he could always make them see something different. Also, if, life and death situation, he could take off the reiatsu suppressor disguised as ear clips. Urahara warned him to not take them off unless he was something really, really, really, really bad was going to happen. That was the only time the smiling shopkeeper went dark and serious. So Aizen kept them on.

In comparison to Ichigo, his reiatsu was held in. Instead of pulsating everywhere, it was kept inside him. This made it more managable. It also didn't give Aizen a clear idea in how much reiatsu he had. It left him in the dark. There were times, he was tempted to see how much reiatsu he had but Urahara's dark look in his mind kept him from doing it.

At least, Urahara's history lessons were helping him.

The Dangai or the crack between Soul Society and Living World would only be open for four minutes. In that short time span, he would have to run through it and exit before the time limit it reached. If he was still inside it he would be very dead. Or deader.

Aizen didn't really believe that to be possible. And he really didn't want to find out either.

The Dangai is filled with Kouryuu, sticker than industrial glue and more deadly. The Kouryuu was dripping from non-existent walls and onto the floor. The floor was covered in bones that snapped as he ran on them. The place was caving in as well, making it impossible to turn around. All you can do it go straight.

With his zanpakuto strapped to his back, the blade as long as he was, he ran nimbly and swore to himself that dying here is not a great way to go. If anything, he will choose the place he dies and the reason he died. He would accept nothing else.

As he sprinted towards the exit, Aizen thanked whatever god or deity that had power that the Seimichio wasn't out. From what Urahara taught him, it looked as big as a train and was covered in Kouryuu. Little did he know, it was out hours before, nearly running over Ichigo and his friends.

With one last jump into the gleaming exit, he was catapulted out into Soul Society. The portal was open several feet into the air, nearly making him plummet to the ground. In a futile attempt to fly, he crashed into the trees, head first, making a bump on his head.

He sat there dazed before a pair of hands grabbed him and dragged him away. Seconds later, a pair of socks and sandals appeared.

"I thought I saw something here." Said a voice before moving away.

Aizen looked up to see a grinning boy.

"Sssh." The boy placed a finger on his lips before indicating to move with a hand.

Aizen followed the boy into a house. Once they were in the safety of the house, Aizen saw that there were other inhabitants.

They were in Ryuutamashikai, the poorest and closest area to Torrorei, where the shinigami live. Here souls were given a number and showed an area where they should go. Rarely can a person find someone from their own time or their own family. Most people don't remember what their past life was and make new lives. Those who have strong reiatsu have to eat or die. Those with strong reiatsu are sometimes found by shinigami patrols and taken into the Academy.

"I'm Shibata." Said his rescuer. "Are you like Ichigo and the others?"

Aizen perked up at the word Ichigo, faltering slightly at the word others. "Who are these others?"

Shibata was happy to explain. "Inoue-chan, Chad-san, and Ishida-san." He paused. "Also a talking black cat."

Aizen had no clue who the other three were but he had an inkling who the cat was. Yourichi-sama must've gone with Ichigo and others. That was good, even though he disliked the evil cat woman for her antics. Yourichi was a master at hand to hand and most likely a former head of the Secret Corps in Soul Soceity. With her, she won't steer them into trouble.

"Thank you for helping me." Aizen bowed. "My name is Ai…Ai-ni."

"Ai-ni?" Shibata blinked. "That's a funny name."

Ai-ni rolled his eyes. "That's why my sisters call me and sometimes Ichigo when he's being a complete idiot."

"You're Ichigo's brother?" Shibata stared at Ai-ni intently. "You don't look like him."

Ai-ni flipped his hand dismissively. "Yeah I know. I don't have orange hair or furrowed eyebrows."

Shibata grinned. "Where are you going to go now? Are you going to jump the gate? Where did you come from? Are you with Ichigo's group? Do you also have a talking cat?"

Ai-ni frowned and peaked out of the window and saw the biggest gates he'd ever seen. The gates were called Torureimon and usually had a gatekeeper guarding it. Strange thing was, there was no gatekeeper. But the gate was still there.

"What happened?" He tunred around to face Shibata.

Shibata's grin widened. "Ichigo went up against Jidanbou and defeated him. There's a lot of talk cause no one got past Jidanbou for three hundred years." His smile dimmed a little. "Then one of the shinigami cut off one of Jidanbou's arms." His smile went back to full brightness. "But Orihime-chan fixed him up."

From the small and rather compressed description, Ai-ni learned that Ichigo was a rather powerful shinigami. Ichigo got into a fight. Ichigo got friends and one who can heal. That was good. It was always good to have a healer on the team. Good. This was good. This meant Ichigo got friends who can fight and who can help.

"You should stay here for the night." Shibata tugged at his sleeve. "Mom and dad says it is okay."

Ai-ni shook his head. "I have to find Ichigo and meet up with him."

Shibata nodded.

"Thanks for saving me." Ai-ni stood, a slight smile appearing on his face. "Hey how high do you think those walls are?"

Shibata blinked at the question. "Are you going to jump it?"

Ai-ni smirked. "Ah, no."

He left the house and went towards the walls. It was nighttime. The lack of light would give him a much better cover than the brightness of day. Ai-ni started off at a run, using shunpo, gathering speed before using his momentum to run up the wall. This was very dangerous and very stupid but it might work.

By using his shortness and speed with a lot of momentum, he should be able to scale the wall and get up high enough to at least jump to the top. This way he won't have to deal with the gate itself. Besides, most people don't look up when looking for intruders.

He was three quarters of the way when his foot slipped. By channeling all his energy into his feet, he jumped up, flipped over in the air and the strong wind blew him towards the wall at very high speeds.

"Awk." He clung onto the edge of the top of the wall with both hands. Ai-ni pulled himself up onto the wall and stood.

That was a bit of a mistake.

Ai-ni yelped as a strong wind nearly pushed him over. This position was decidedly bad to be in. As he weathered the winds Ai-ni thought he felt Ichigo's spiritual pressure. It was outside the walled in area. Damn, that meant Ichigo wasn't inside yet. Ai-ni turned to jump down when the wind blew him off the wall and into Torrorei.

"Umha." He landed on his feet, absorbing the shock through his legs. He stood, looking at the looming walls. Damn, now he can't get over the walls due to the large population of shinigami. He really didn't want to alert them of his presence.

"At least they didn't catch me yet." He muttered to himself, reaching over to touch his zanpakuto in reassurance.

"Alert, Alert." A loud bonging sound resounded. "Intruders in the City! All Personals Should Report To Their Stations."

The heck? Ai-ni hid in a shadowed area between houses. No one saw him. And he couldn't feel Ichigo's reiatsu anywhere near this place. So who was invading? And even if they did see him, they would've found him already.

What was going on?

With that thought in mind, Ai-ni disappeared into the shadows. With the shinigami in a heightened state of alertness, he shouldn't draw attention to himself.

"I Repeat Alert. Intruders In the City! Please Return To Your Appointed Stations!"

Something wicked was going on in Shinigami Town.

KKKKKK

Meanwhile, Ichigo was fast asleep from accidentally causing an explosion. He had Yourichi's tail in his hands and was bending it in really bad shapes. The others tried to stop him but alas, Ichigo was making Yourichi's tail into an art form. The frantic wails of Yourichi did not make Ichigo falter.

In the end, it took the whole group's effort to yank Yourichi's tail away from the crazy hands and into safety. Sadly, her tail was still bent in many shapes. And Ichigo slept on.

KKKKKKKK

KKKKKKKKK

Ta, dah. Chapter two!
