I have to say that I don't much care for the fighting aspects of this manga (seeing someone so dominant isn't very interesting, and they're not drawn all that well either), but I am pretty okay with Cain's integration into the world of nobles and accrual of fiancees. There's some humor in showing people in positions of authority (like the gods and king) with undignified expressions of human emotions. I'm not sure how I feel about Aaron.
More than anything, I think I primarily enjoy this because I enjoy the isekai genre. It's not the best example of such a story and I probably wouldn't recommend it to anybody, but it has those isekai hooks that seem to make me swoon (metaphorically) and it's not bad enough to repulse me, so here we are..
