The core concept here is just stupid. "Do what I say or rape!"
I went to the webnovel to see how bad it was, aside from making it clear that the girls are broken it's largely glossed over... which I fear the manga may not gloss over quite as much. Then they start talking about how they think MC is some special power equal to armies potentially and they're excited... What? You think someone is going to be loyal to you after you GANG RAPE people for no reason? This is just brain dead stupid why are there so many lazy authors who just go that route for easy shock material? All these actions will accomplish is making sure the people involved do everything they can to pay you back for what you've done.
