That's basically the reason I'm reading this instead of Isekai Apocalypse, the female protagonist that isn't a damsel in distress. So rare in the industry.Isekai apocalypse mynoghra is the better version of this story, all the way down to the moral ambiguity, kingdom building, even RTS elements.
Still, I am a sucker for an edge queen, and the story never dips too far in quality so if you hang in there, you'll get some intrigue.
