[................. but. that's too vague. i don't. how do i. but.]

I'm... I'm Ilya's sister. There was a really big fire when I was young and everyone around me died, but Kiritsugu saved me and adopted me. And then we were on the run for a long time, and after he - [ENDED UP IN KIREI'S BASEMENT NOPE NOPE NOPE CAN'T SAY THAT] - he disappeared, I found Ilya and we lived together.
