@Lichzim I'm basically think of a doujinshi called sword dancers where we have a female Archer that has white hair. It's on mangadex
https://mangadex.org/title/8957/fate-stay-night-sword-dancers-doujinshi
So that means future Illya is now vulnerable and could die if it means past illya saves the world. But where is the salvation for future Illya? Going back to the past, she sacrifices her identity (can't be two illyas in one timeline) and basically has to reinvent herself. I see
>Miyako hits on Yuno on page 3
>Yuno goes blank and doesn't compute
>Yuno hits on Miyako on the last page
>Miyako doesn't notice
Is Miyako too pure or is being Yuno just suffering?
