Fanfics de Final Fantasy VII com Red XIII - Tag Mystery

What if a girl ends up another world? Only to find out that she is an assassin from a castle that is hired to kill someone but is mistaken by an elfen girl to be a princess of that castle that she is an assassin of... But of course she doesn't believe it, that is until her target's twin brother overheard a certain conversation and decides to take matters into his own hands. He kiddnapps the girl and takes her to the very organization that holds the very person who she supposed to kill... Only to get trained by him and put in a predicament... She has to also work with his best friend to kill her target...
This may all sound confusing but it will get clearer on what the Shadow Warriors Organization is all about...
And what this girl's true purpose is...

What happens if almost all soldiers were created for one purpose and one purpose alone? And that is destroy everyone and everything in thier path. While living out normal everyday lives just as regular humans.
But what if something goes horribly wrong and the latest experiment gets infused with wolven dna and ends up going haywire only to be put down a second later by the very ones who created him. And this is experiment X-201. Or better know as Cloud Strife.
Cloud is an sixteen year old experimental android that had to be put down many times. Due to a lot of failures and collapses that happened many times. One was due to dna insurgance that had caused a lot of difficulties during the making process. And one was due to the fact that someone made a very horrible mistake...
And this one was recent...
By infusing his dna with that of a werewolf. And a human.
So now like most androids that we're built in the same laboratory as that of thier fellow soldier, he became one himself. But was the most human of them all.
And the most dangerous.
Especially since he is the very cause of a time warp that just won't go away.
And who does drag along with him?
A young ninteen year old girl who ends up sharing a predestined relationship with.
And ends up becoming her... PET.
Things can't go wrong can it?
Oh yes it can.
Since Cloud is no longer an android...
But a soldier.
A 100% human soldier.
And that means one thing.
Unlike his predesors he can feel.
And boy is he pissed off.
