This adult visual novel starts off hard, with the death of one of the main characters, and doesn't stop there - another one is tortured, thrown in a cargo crate with her dead parents and has to turn to cannibalism to survive.
From the end of the first episode, it is made pretty clear in what direction everything is happened - Wilfried himself states what the fate of the witches will be once he "wins" - and he does carry out what he says, at least with one.
