Don't you want to see bullish rich lady fall because of her arrogance?
If only it were so 'sophisticated'. I admittedly skipped most of the h-scenes, but it basically starts off with her going to loot the dungeon because fantasy world. She didn't really listen, the monsters and humans had some trade agreement and no harming each other, so she's a criminal. She is told so and asked to stop, but proceeds to loot because she was a rich bitch and wants to keep being one. When she came back, she seemingly forgot she had cheat powers that allowed her to stomp the demon lord and just allowed the villagers to rape her and the mayor to threaten her over taking away the loot she got from the dungeon. In 'retaliation' for allowing herself to get raped by the villagers, she allows the villagers to rape the demon lord because she tattled about her crimes in the dungeon, so the logical conclusion was overpowering the demon lord (that's vastly more powerful than the villagers) and allowing the villagers to rape her as well and turn her into the villagers' cumdump for the humiliation she had to suffer (due to her own stupidity and incompetence alone)! And raping the demon lord is apparently a-ok with their non-aggression treaty or whatever. Correct me if I'm wrong, I mostly just skimmed and skipped, but this seems to be the level of sheer stupidity we're dealing with here.
There's also some h-scenes that involve her getting defeated and raped by monsters, this might give her some vague justification for having it out for the demon lord, but since you have to actively try to lose, I never got any and the story made even less sense than the horrible 'translation' alone does. It had some interesting concepts thrown in, like the demon lord getting her abilities overwritten by useless peasant abilities through sex or something, but the 'translation' ruins anything based on words and ideas. It's just shit all around, there's dozens of games that do this trope competently, this doesn't seem to be one of them.
