I like that idea about the sisters. "Snow and Sky" (Sora = sky, Yuki = snow) perhaps? But that'd lack the 2 in the title so probably not that.

"Two Sisters" is just too generic to make a good title, though it could mislead people into thinking it's about one pair of sisters when it's really about the other (either Sorano/Yukino or Mira/Lisanna) or be about both pairs.

It could also be about the Juliet any Hyne.
