Urahara was briskly walking towards the barracks of the first division, he had asked for audience with several captains and this time he didn't want to be late one second.

He arrived on time, although a bit winded. He never got winded, he never hurried either, so when he entered the meeting room in his current state the present captains were aware that whatever had happened must be important.

"Urahara Kisuke, I trust that you have gathered us here for something important?" Yamamoto said, keeping his straight face.

"Yes sir, I'll try my best to keep it simple and short."

The captains nodded, the ones in the room were Shunsui, Ukitake, Kuchiki Ginrei and Unohana.

"You see, ever since I became the captain of the twelfth, I've been using my spare time on one of my hobbies, trying to understand how time itself worked, now, it never was really interesting, I used it more as relaxation; but a few hours ago I... received a message through the instruments I used. I think it's from the future."

As he promised, he had kept it simple, but even so, everyone needed some time to adjust and for the news to sink in.

"Are you certain? And what is the message?" Yamamoto was the one to recover first and no one said anything else since Yamamoto asked the two questions that were on everyone's mind.

"Yes, I am certain; the message is written down here." He pulled out a piece of paper out of his robes and handed it to the General.

Yamamoto first read it to himself a few times, before he read it to all the people present.

"The message says:

I am coming from the future to stop the Gotei from being destroyed.

Urahara, do not tell the vice-captains of this.

I will be there in a days time."

"It could be a trap." Kuchiki Ginrei stated calmly. No one had anything to add to that, it could very well be a trap, they had no way of knowing.

"Urahara, how will this person arrive?" Unohana was the one to ask.

"Whoever it is, he or she will arrive, I can actually make an entry point wherever I wish, but without one made, that person could arrive anywhere in Soul Society."

"So it cannot be avoided... very well, is there anything you wish to add Urahara-taicho?" Yamamoto said, still thinking about the strange development.

"I can construct the entry point and have it ready in 2 hours at most, as of right now, we have 20 hours left."

"Very well, is there anything any of you wish to add?"

"We sould be ready for a fight just in case." Ukitake said speaking for the first time during the meeting.

"Noted. Urahara-taicho, you will construct the entry point in one of the empty buildings I show you, in 20 hours all captains will be assembled for the meeting and we shall see what happens then. Dismissed!"

The hours had passed quickly and Urahara had built his contraption that looked surprisingly simple for something that should be complicated.

Everyone was gathered already.

The machine Urahara had built was a simple circular platform with some cables connected to the monitors he had set up.

Yamamoto was standing across the entry point with captains to both his left and right. When he had explained what was going on some were outraged, some were yelling that it was a trap and some (Kiganjo Kenpachi) were silent, not really interested. After he had managed to calm them, they had prepared themselves.

"Draw your swords." Yamamoto barked out and everyone complied.

"1 more minute." Urahara said from behind his instruments.

The minute passed in silence, no one really daring to say anything.

Silent buzzing started emanating from the platform and everyone gripped their swords a bit tighter.

There was a gust of air and a powerful reiatsu appeared in front of them.

The person that appeared was a tall young man with a giant cleaver-like sword resting on his shoulder, but the most prominent was the haori of the first squad he was wearing.

He was facing away from them, but Urahara and his monitors were right in front of him.

"Urahara-san? I thought there would be more people waiting for me."

Urahara didn't say anything, he was surprised that it actually worked, he just looked at the general and the rest of the captains behind the time traveler.

Ichigo noticed the look and turned around to see who else was there.

"Old man, you look the same as the last time I saw you..." he noticed that they all held their swords ready.

"Oh, right, you think this is some sort of a trap;" he started digging through his robes and pulled out a letter, "Old man, this is for you from, well, you... you knew you wouldn't trust me so you had a letter for yourself written and... just read it, I'm already lost." Yamamoto carefully took the letter and opened it, inside he saw his own handwriting.

After reading it he closed it.

"Sheathe your swords." He ordered and everyone complied, some more readily than others. Ichigo placed his sword on his back and it wrapped itself in bandages.

"I'm Kurosaki Ichigo, acting Commander-General from about 100 years in the future." this got him some odd looks from the group. "I know you still don't trust me and frankly I don't care, I'm here to save the future, after I do that I'll leave."

"What do you mean 'save the future'?" Kyoraku asked, still eyeing Ichigo with suspicion.

"I'll give you a short explanation now, I have this thing which can show you my memories, I'll show you the details later, right now the traitors need to be stopped."

"Traitors? Who are they?" Yamamoto, never being one to go ignore any kind of betrayal spoke first.

"Aizen Sousuke, he's a lot more powerful than he shows." before his voice could be drowned out by the gasps and yells of denial he continued, ", Old man, you had to use Ittokaso on him, and it still did nothing more than just singe him a bit."

A lot of eyes were on Hirako now, but instead of being surprised he was angry.

"I knew there was something about the bastard, but betrayal?" he was seething and was on the verge of storming off to slay the bastard.

"Calm down Shinji, if it was that easy to just kill him, I would have sent a message with a warning and there wouldn't be any need for me to come back. His Kyokasuigetsu is a really powerful Zanpakuto, you are all susceptible to his hypnosis, he can make you attack your allies while you think that you're attacking him..." he saw the disbelief on their faces. "Here's some proof of it."

He held out a fist sized orb and a projection appeared on the wall.

They saw a redheaded man with a broken Zanpakuto from Ichigos eyes.

"I can use this tecnique only once, but it will leave an opening, use it."

Ichigo charged towards Aizen, his timing perfect, his aim perfect, and yet his sword was stopped by a single finger.

The image blurred and the scene was now different, Aizen was floating towards the sky on a piece of land inside a Negacion. Together with him were Tousen and Gin.

"No one stands on the top of the world. Not you, not me, not even gods. But the unbearable vacancy of the throne in the sky is over. From now on...I will be sitting on it."

"Deluded bastard..." Hirako was still angry.

"Not really, it took him centuries of planning and careful action, but he became immortal eventually."

"What!?" those who didn't say it, were most definitely thinking it.

"What time is it now? I want to get rid of him as soon as possible." Yamamoto narrowed his eyes at this.

"That is unacceptable, he is to be captured alive and imprisoned."

"And I say that THAT is unacceptable, he already managed to escape from Muken once. I don't wanna give him any more chances."

Once again, people were surprised, Muken is not a prison that you should be able to escape from.

AN: That's as far as I got, as usual, you're free to borrow the theme and even the stuff I have now, but only if you notify me, I want to see the results.
