The concept of the story is really interesting, it's not your average isekai where the MC's main goal is to defeat a Demon Lord or make peace between the demons/monsters and humans or build an advanced settlement but instead it's a isekai where the MC's main goal is to defeat his yandere sister that gets reincarnated to the same world as him, the beginning might be unsettling for some tho. Also, people are talking like the author made the MC a pedo, I get where they get this but it is a big stretch, too bad this manga got axed.
