Now, I've never read a smut before, but sometimes I was like, "Wait. Why are they naked?" This happened maybe only 6 times throughout the entire manga, but it is still as puzzling as hell....
Other than that, I found the story to be kind of slow, but fast enough that I didn''t drop it. Be warned, the mangaka holds no hesitation in killing off characters. They don't kill them off willy-nilly, but be careful not to get too attached to any of them.
Everything other people have commented about the "queen" as the antagonist is true. I won't repeat it again.
The coolest part was that every once in a while, the manga would have a few pages saying "And in the early 19th century, an archaeologist found the records of place-some-activity-here, although no-one ever knew why something-something was something-something." And in the arc before, the something-something's were explained. I didn't make much sense, did I? Anyways, the ties in with real life were SUPER cool.
I, personally, really liked the art, and in particular, the skirts.
The end, in my opinion, almost was amazing. There are two obvious ways the story could have gone, but the mangaka picked the way that I liked the least. It was not a bad ending, but I think it could have been better.
In total, not bad, but not good. I'm not planning on reading this one again. If you are into wars and relationships, read Red River because it may be your cup-of-tea.
Something that I just remembered: The mangaka does something entirely amazing with the relationship at around chapter 30. It was soo beautifully crafted that I was (and am still) in awe. I will reinforce what I said about the manga being good for those who like reading about relationships(and not necessarily only romantic ones).
