Author's Notes: Xion in the world of Final Fantasy XIII. How sweet is that?

Timeline: Before Episode Zero: Promise

Warning: STRONG LANGUAGE and major Xion OOC

Description: Xion lands herself in the World of Final Fantasy, in the 13th Fantasy. How will she interact with Lightning and the others?

Prologue: Arrival START

My name is Xion. I was originally a Replica of a Keyblade Wielder named Sora. I wasn't his image, but an image of the one who he cared about most, Kairi. Because I was a Replica of him, I can wield the Keyblade.

I was originally of Organization XIII, a group of Nobodies who wanted to create their own Kingdom Hearts so that they can acquire hearts from it, thus becoming complete beings. But most of them have faded back into darkness thanks to Sora, except Roxas, who also wields a Keyblade, who he fused back to.

Even though I was with the Organization, I was never really a part of it, which is why they never name themselves Organization XIV. I was a puppet, just in case Sora and Roxas proved useless to the Organization's plans.

To stop them in their tracks, I had Roxas delete me so that I could go back to Sora, which I did. Some of his memories return because of that. As for me, I was supposed to be inside him, but…

I found myself in the crossroads of darkness, where the Heartless was ignoring me, despite me feeling that I now have a true body, soul, and heart. Twilight Thorn then appeared, and after a fierce battle, I won, but fell into a portal of darkness.

I was then transported to the Dark Meridian, where I found one of the three tragic, original Keyblade wielders, Master Aqua. She was wandering the Dark Realm for years, searching for her friends.

She took me under her wing, training me in the ways of the Keyblade. During that, I developed a different personality from my original one during my time in the Organization, and developed new skills and abilities.

My Master Qualification Exam took place in my Awakening, where I defeated Anti-Xemnas to become a Keyblade Master. With that, I renamed myself Xion Hikari. I got rid of my Black Coat, but still kept it as my new outfit was the same design as the older Kairi, but in the place of pink, was black. Aqua then bid me farewell with the promise to meet again, as we went our separate ways.

And that's when my new adventure began, when I fell into a dimensional portal.

...XIII...

Xion POV

"Ow!"

I landed face first on the ground, as I fell from a portal I stumbled into. I rubbed my head as I notice the portal disappearing into nothingness.

"Just great," I moaned, looking around, "Just where the hell am I?"

Normal POV

Xion looked around in what appears to be a deserted village. It looked nearly destroyed, but still standing. She then toured around, trying to find clues to where she is, for she gets the feeling that she's not in her own world anymore.

"Crystals?"

Then air was filled with crystal dust, leading to the conclusion that she was in a world that involves crystals, confirming that she's in a completely different universe.

She was then suddenly surrounded by all sides by strange, crystallized creatures. Some were huge and humanoid while others were just flapping arms.

"Gah! What the fuck are these things?!" she screamed as she un-drew her Dream Sword.

The creatures then attacked, leaping up at her.

"EVENT HORIZON!"

She wildly jumped around, slashing anything that got near her and summoning pillars to cut though them. When the attack ended, the defeated monsters wisped into nothingness.

"That should do it." Xion said as she turned around to find more of those monsters, only in a large group, charging at her.

"Well, fuck me…"
