The added fantasy in this anime helps it stand out among other historical anime. Despite what most people would think, the fantasy and historical drama themes are woven together perfectly. The romance isn't exactly the best, mostly because it's just an afterthought in my opinion.
The story ties your thoughts on what the participants in war go through to protect their honor and country. Though like most historical dramas, it's a real tear jerker. The plot makes it so that you start to understand what the characters are feeling throughout the many battles they fight.
One of the downsides to the anime was that Yukimura Chizuru can't really protect herself. It makes sense, yes, but I have yet to find a good historical anime that features a female protagonist that doesn't constantly need saving.
Overall, this anime is very enjoyable and has a well-thought story.
