Let justice be done, though the heavens fall.
However overpowering the rest of the world, these both were not everything there is about the anime. The anime had a lot of other characters, a lot of strategy involved, and most of all, it displays the true nature of politics, basically of the old times. The way everything has been depicted in the anime, I believe, despite the fact that all the concepts involved were far too otherworldly, this anime might have been the biggest Slice of Life anime for how closely it closely it imitates the real world's concepts, values, ideals and systems.
It isn't everyday that an anime which can combine the concepts of politics into a love story, which seems to be set in an extremely different and fantasy like situation, is aired. The story is so beautifully put, yet it pains the heart at points. But keeping aside all the melodrama, there wasn't much action in the anime to boast about. It was decent, but it was more about a guy fantasizing about a girl, and another guy doing the same. It wouldn't be wrong to say that this anime almost took a harem turn, only to increase the negative rating it could receive. The music of the anime was by Sawano Hiroyuki, which is my personal favorite composer, who has also given music for the recently released Anime title Owari no Seraph / Seraph of the End. The animation was by A-1 pictures, who seemed to have been really busy with all the projects that it redirected most of its resources onto this project, leaving other anime (like Denpa Kyoushi) with less budget to actually become a good anime.
Conclusion : The anime has a fair amount of romance, lots of melodrama, a somewhat happy-ending, all put together in a Science Fiction setting. The animation is what is the biggest plus pointer about the anime, followed by the music, but the letdown to most people is the climax, which might have been the most perfect depiction of politics that we have seen in an anime.
