Be advised, as someone who was masochist enough to read the other works by this artist that aren't available here, I can say that they can seriously go to dark places.
I expect this manga to delve into fully depicted rape (Ch1 was nothing), extreme gore / twisted violence, and exceptionally dark characters, much worse to what we've seen so far, at the bare minimum. If the girl says, "I can kill a baby," this mangaka is the type who would have no issue portraying such an act in a full double-page spread.
I've even seen comments in Japanese of people wondering if the mangaka is right in the head, lol.
I'll probably wait til this ends, so I can read it all at once, but just wanted to leave this here.
