I love the plot because it really shows how unnerving it is, It's like the heroes are their slaves and the NPCs themselves are okay with it because they're already dead.
I can take Dyne(not in a fight) but DAYUMMM we love gentle giants, Love Caius and Kouichi's dynamics they're such a healthy couple which is unusual for smutty mangas
Why the fuck did you need to add 1ncest you weirdo
