well t's the author's manga so they can choose t
how they want the plot to go, it doesn't have to follow typical story lines, and if your're uncomfortable, DoN'T ReAd It. Plain and simple.
thought I'd never know that unless you told me
I think the other person can't handle the fact that people very rarely, if at all, like EVERYTHING they see in a story. They definitely seem to think this isn't a typical story line. Ironic. And authors are writing stories that an audience will read.. If they can't handle criticism and grow because of it, like every other worker that deals with the public to some extent, then maybe this kind of job was never for them.
This is no way close to arousal sex, smut theme thing at all. The demons used their power to force the women, girls to have sex with them. The whole story is about the girls, girl got assaulted in sleep and reality. I feel uncomfortable with this. I hope authors out there quit the plot like this. Well, bunch of hentai out there could do if we want to read or watch something like this. Here I still expect better quality smut manga.
