"The story was simple."
No, it really wasn't. Still confused. Doubly confused why so many women in this world find the sad guy with sad eyes so attractive, but hey that's anime.
Ynow for a story in a medieval setting there's an awful lot of progressive bullshit in it. Why the fuck would a noble family with powers tied to their lineage not only say blood is not important but neither is marriage. Are they gonna start saying having children is not important because you can...
A lot of deus ex machina shit going on. Apparently they have crystal cameras and the brother just happened to be alive and show up. Stuff like that should be foreshadowed a bit better.
