Once upon a time a couple trolls in her circle of nearby acquaintances got into a bit of an argument that... snowballed and sort of spilled over into the general surrounding area as it turned into a chain of crazy murderous revenge and then less specifically directed mayhem and murder. Hirune was intending to quietly sit it out, but while she will almost never pick a fight, she'll finish ones that get brought to her, which was how that ended.

ALSO yesssss she would love to discuss that with him at length because man does she like to words words words about social philosophy, even if the other person doesn't see eye to eye with her—that just makes it more challenging and therefore more fun.
