The game has been changed, so what is on 99th Floor of Aincrad?

Four years have passed since Zero Requiem, and for Lelouch vi Britannia, the immortality that came with inheriting his father's Code is a fate worse than death. Having been forced to hide away from the world to preserve the peace he won, Lelouch lives the life of a captive or a recluse, until C.C. brings him a set of Nerve Gear - the gateway to a world he can live in.

No Summary for now.

After the Zero Requiem, Lelouch has returned to a world of eternal solitude. And yet, evil is not gone, and Lelouch has to decide whether or not he can muster another facade to save the world from destruction. And who would've guessed that the evil he faces finds its root in the infinite worlds of virtual reality...

He didn't know whether this was fiction or reality. But life has a nasty way of digging up old wounds from a past life. For Kirito the Black Swordsman is actually Lelouch vi Britannia reincarnate, and his precious Asuna is Shirley Fenette. What happens when their past life memories interfere with their lives now? The young swordsman will discover the secrets of his past.

My whole life was a gruesome game. I created Zero Requiem to end this bloody game of chess once and for all. But I was given another chance to live in a world without racism and discrimination. For once i thought i will be allowed to live in peace but fate had another plan for me. As I Lelouch Vi Britannia am thrown into another game of life and death!

When Lelouch Vi Britannia died, the collective unconscious owed him a debt. Now it seems it can be repaid. For one who never had time for games, it was ironic Lelouch would find himself trapped in one. But unlike the other ten thousand players of sword art online, he was different. The glitch in the code.

How would the story change if Zero had a Knight that helped him from the start? Who was just as bitter about Britannia as him? Who fought for similar reasons? Who helped not only him but the witch and the Queen as well? Who knew what it meant to lose someone and give everything for a loved one? [rated M cause I'm nervous]

As a result of the Zero Requiem, Lelouch has been killed and sent to another world by the Collective Unconscious. There, he finds two worlds that are completely different from his own. One being present in what he knows to be reality and the other being present in a video game called: Sword Art Online, and funnily enough, he just so happens to own a copy.

Lelouch need to die to bring peace, but that did not meant he will just die quietly. He had a plan that even if he die, his mind will continue to exist, protecting the world. Still, after years protecting the peace, he found himself trapped in online game that C.C force him to play without a way out with her. One-shoot.
