I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Chohei Kambayashi's Yukikaze was military fiction that even I, a military fiction newbie, could follow along with. This, on the other hand, tosses you into the deep end with a map of Europe labeled with new country/empire names and a few footnotes. I suspect some of what's going on right now might have links to real European history around World War I and World War II, but I'm not following along well at all.
I really liked the bit from Major von Lergen's POV, as he struggled with the knowledge that he was going to have to give Tanya a highly regarded medal, even though he knew from her academy days that she's a dangerous monster who shouldn't be given any opportunities to rise in the ranks and potentially be put in charge of other human beings. We're back to nothing much happening, though, now that that battle is over. Tanya's testing an experimental orb. I really need to look up some screenshots of the anime, because I can't picture the flying scenes at all.
