I do have to say though, the MC is a fucktard. It's not just Marie, but he also caused some of this due to his own ineptitude in growing the balls to take a life. Dude pussy footed for so long, that everything came to bite him in the ass if he only properly resolved the problems instead of letting all of them go alive. Sure, there's no need to kill every enemy you go against, but at the very least the principality enemies should have been killed, including Hertrude or whatever her name was. I don't care for her background history or whatever, as the author seems to have her as a somewhat more important character than just simply a villain, but I really couldn't care less about her. Realistically he should have capped that bitch during the initial fight he had with them.
