There is a goal to have a pure-yuri route for Eillana's storyline, yes, but the code needs some reworking to make it happen properly for a yuri-only option. The goal for now is to finish up some of the work with redoing UI (stats screen, map screen, class selection, skill selection ,etc) and then start on redoing the relationship system at some point in the future to make it easier to keep up with.
I also need to improve my ability to draw two-person scenes a bit, which I'm working on now as well.
