Author's note: Yup, I'm starting another story again. I saw lots of other Bleach fanfic about Ichigo and time travel. Then, a thought came across my mind, "Why not Aizen?" So here I am, with this story called Second Chance. Enjoy!

"Speaking."

'Thought.'

'Zanpakuto talking.'

Chapter 1: A new Chance.

Human fear that which they cannot see.

The war with the Quincy had raged on. The power of the Vandenreich was beyond what Soul Society could ever imagine. Almost all of the captains and lieutenants had been killed, with other countless seated and unseated officers. Even the head captain, the famous Yamamoto Genryusai Shigekuni, stood no chance against the leader of the Vandenreich. He put up a great fight against the Quincy leader, using everything he had, and still he was among those killed in the end. Soul Society was destroyed.

And just like Soul Society, Hueco Mundo was also no more. All of the hollows had either been killed or captured to become their slave. With the fall of both Soul Society and Hueco Mundo, the world had lost its balance. Seeing the world become unbalanced, the spirit king sent out his best army to fight the Quincy. They were the Royal Guard, the special force of the king, the best of the best. And yet, they were no match against the Vandenreich.

As the army of the Quincy moved on, they assassinated the king in the spirit realm. They killed anyone who dared to oppose them. And with the death of the spirit king, everything was thrown into chaos.

The new spirit king, formerly the leader of the Vandenreich, ruled with iron hands. Every day was a struggle to survive. There was no peace at all.

But within that dark chaotic world, there was still a group who had yet to give up the light known as hope. They kept fighting the darkness without yielding to its overwhelming threat.

This group, known as Knight, was a group that consisted of eight people. Every race was present in that group.

Grimmjow Jaegerjaquez.

He would be less surprised if it was Ulquiorra or even Starrk, but Grimmjow? Never in his wildest dreams could he have imagined that Grimmjow would be the one who survived this long. Grimmjow Jaegerjaquez, representing the arrancar race.

Ishida Uryu.

The only Quincy on the light side and the only one who dared to fight against the king of Quincy without any fears. Ishida Uryu, representing the Quincy race.

Inoue Orihime.

She was still a cheerful girl with unbelievable kindness in her heart. But at the same time, she had also changed. The clumsy little girl he kidnapped all those years ago had now turned into a really powerful warrior. Inoue Orihime, representing the human race.

Yasutora Sado.

His loyalty was definitely unquestionable—he would follow their leader to the very end. Yasutora Sado, representing the fullbring race.

Kuchiki Rukia.

Everything about her had changed the moment her brother died to the point where she was almost unrecognizable. She was cold and merciless, an assassin, a perfect killing machine. She trained every day, all to avenge her brother. She had vowed to destroy the Quincy army. Though, she was still how she used to be around their leader, and only their leader. Kuchiki Rukia, representing the soul reaper race.

Kazuki Emiko.

Enigma was the best word to describe her. Even for a genius like him, she was still a confusing one. She was the last to join their group. Their leader was the one who found her wounded on a dark street alone in the human world at night and brought her to their group. Kazuki Emiko, of a race still unknown.

Aizen Sousuke.

Then, there was himself. Yes, he, Aizen Sosuke, the biggest traitor in Soul Society, the master of plans, the most genius man in all of the three worlds, second only to Urahara Kisuke. Soul Society needed to use every available force they had, even it meant that they had to ask for help from a traitor like him. Aizen Sosuke, representing the third dimensional being race.

Kurosaki Ichigo.

And of course, their leader, the human with a reaper and a hollow power inside him, the number one guardian, Kurosaki Ichigo, the man who changed him, the one with the power to casted away the painful solitude from his heart, the only one he could ever trust to guard his back. Kurosaki Ichigo was someone worth to protect. He had always been the unique one and, not that he would ever admit it out loud, but Ichigo was the only one he could ever consider a friend or a family member. Kurosaki Ichigo, representing the vizard race.

And… How again was it that he was in this position right now? Lying in his own pool of blood while feeling that his life force was disappearing in every seconds? Oh, that's right, this was the last battle between their group and the Quincy army. The winner would take everything, and the loser would lose everything. They were fighting against the Stern Ritter while the leader of both sides were fighting one on one. Both were evenly matched until one of the Stern Ritter shot a sneaky attack to the orange-haired Vizard. He hadn't had enough time to cast a kido spell, so, he had thrown his own body in order to protect Ichigo. A very stupid move, but he didn't regret it. He was able to save Ichigo's life.

He could hear one of his comrades shouting, "Hang on! Hang on!" but he knew he wouldn't make it. Without the Hogyoku that he had lost in one of the many battles against the Quincy army, he was left as a mortal being. Soon, he would become just one of the many who fallen in the fight against the Vandenreich.

"I just wish for this to never ever happened. This war and your death, I reject."

That speaker spoke in a really small voice, barely above whisper, and the last thing he saw was Orihime's teary eyes before he was blinded by a white light instead of the darkness that supposed to greet him.

And thus the sword of fate fell anew.

The second chance had began.
