It was very good, which is rare for a ruthless pedant like me to say. The only problem I found was the repetition of using Kira to start a paragraph and the repetition of the use of 'she' to start sentences. I'm not saying you should use loads of fancy words, that's a no no, just vary it about, otherwise it makes the style seem slightly halting and detracting.

Looks like a good prologue. A bit short but from what there is looks like a good story.
