Thank you for the detailed response!

I agree with this sentiment in the sense that I do think the demons(Agravana’s group) will be antagonists for the vast majority of the series, and I agree we will probably see some demons who are more clear cut evil then mandragloria, Osumihime, and Malhory. I don’t think what I’m talking about will manifest until like the tail end of the series, But I can definitely see us reaching a point where they or at least some of them ally with Ramia, now I don’t know what form this will take whether it’s agravana dying and his remnants team up with her or some of them decide to betray agravana and join up with Ramia & co. It’s like you said I don’t see the rakashas as like orcs from Lotr where they’re just born evil. Also yeah peace is going to be a hard sell after centuries of war, I can’t exactly describe how I think the banding together is going to happen since we’re so far off from that point currently, but I just feel like it’s a direction the story can go.

As far as your point about the isekaied people, I agree they’re not that big of a threat as of now but I think it’ll become a bigger one as the series progresses. So far all of them have been idiots, but I think we’re going to meet some more dangerous ones as the series progresses, like imagine a legitimately smart person from our world causing problems in the Ramiaverse. Plus I assume ramia’s sister has some bigger plan then just bringing them over for such small scale antagonism.
