Huh, it seems like Obsidian and Yu have met at least twice before: when Yu was a kid, Obsidian threw her off a cliff, then met her again when Yu was, maybe, 10 and killed Father William. Her dialogue here implies that either both times, or just in the latter situation, Obsidian had gotten quite emotionally vulnerable with Yu, possibly using her to get to William, her true mark. Yu's over-the-top violence may be thus viewed as (though not excused by) the anger of a deeply hurt serial ex.
My guess is that Obsidian is an assassin for the (criminal) underworld, albeit a reluctant one judging by Yu's second flashback of William's death. Her memories appear to be wiped clean after every hit, allowing her to blend back into the society as a lowly succubus. I do not think that Yu was her actual mark when she threw her off a cliff, otherwise she would make sure she was dead. Rather, I speculate that both times, Obsidian was actually protecting Yu, but "disposing" of a witness in a way that she was sure to survive. Of course, we'd have to wait and see if any of the above resembles the author's plot.
