Absolutely heartbreakingYou aren't the first person to ask about Hureya. I was contracted to produce her bad ends and aftermath of defeating her, with the brief specifying the whole stocks thing. However after writing that it felt a little too mean to just leave her there forever, particularly as the player can't help but get to know her motivations, so I also added the option to let her go. Unfortunately, this then generated the impression that more content is to come for her. And no, emphatically, there isn't.
Would absolutely love to have more of her or a very similar character in the future
Honestly even just a little event/ability to meet up with her again and roleplay existing sex scenes would be amazing
