I Refuse to be the Mid-Game Boss! [OP MC, Slow Burn Isekai]

One day, she's going to murder her own village. She doesn't know this because of some vague prophecy given to her or because she wants to do it as revenge, no, she's been Isekaid. Specifically the reincarnation kind, the terms aren't unfamiliar to her, she's read some books with this exact premise even. In those books, the person who gets reincarnated ends up in a peaceful world and becomes some kind of badass. That's their fate. Hers? She goes to one of the worst worlds anyone could have gone to, one riddled with giant rat men, monstrous creatures, and maddened sages. And to top it all off, she's destined to join this band of mad men and become a monster herself, one who will eventually wipe out her own village. But she wouldn't let something like fate or destiny take control of her future. She's gonna take it by the neck and wrestle her way out of such a tragedy, no matter the cost. The problem is though, in a world teeming with monsters, she might have to become one herself in order to save it. ============= What to expect: *Smart MC who knows how to game the system and work her way around it. *A fairly villainous main character but she's not outright evil however and has some morals. *A slightly grim-dark world teeming with poverty, inequality, and death. *Monster hunting and level grinding.
