User blog comment:IcyDevil34/Next Key LRIGs?/@comment-35126423-20180920070419

This seems amusing enough, i think Ulith has a pretty high chance as it seems likely that we'll get another black LRIG next set and she's probably considered more important than Nanashi.

If i was gonna take a really out of left field guess i would say something like her being a white lrig(white also seems likely to get another LRIG next set) with poison fangs; but realistically she'd be a black LRIG with something like labyrinth SIGNI or something.
