Added Check Character as Saber has so many clones I have no idea on whether this is her or not.

Eyes are green so that discards all the Alters (their eyes are yellow), breasts are medium-sized so that discards the Lancers and summer Ruler (their's are huge) and her hair is styled in a french braid so that discards Lily, MHX and and MHXX (they wear ponytails)... I'd say she's the original Saber.
