Looks like my series have quite some resemblance to this guro/horror game Dream of Gluttony

and it totally could be this village :)
They even have older boy and young girl living in the house like that alone who occasionally kill guests (and everyone there kill their guests ;)
So you could imagine that some characters like in that game exist here too :) It even has those 2 twin sisters that I was planning to introduce.
So pretty big coincidence and it may be worth checking that game as it is pretty interesting concept.
