I had hoped to review this before Christmas.

The Kingdom of Alsace has been caught in a middle of a power dispute between the higher Kingdom of Brune's Dukes, having been captured by the rival nation of Zhcted and it's war maiden Eleonora, Alsace leader Tigre joins his captors in saving Alsace and preventing Brune's Dukes from seizing the throne, leading to a wider war for power involving other War Maidens and armies all the while Tigre inheriting a black bow and it's power to change the tide of battle.
This anime badly wants to be a harem as it makes every effort to make it's female cast standout but still holds back in favour of it's tactical warfare blueprint as each battle is described like a battle out of Dynasty Warriors Empires, but it means that the anime is treated more like a glorified game of chess rather than an action epic, not a bad thing, I actually like chess but that doesn't exactly inspire excitement.
The dub is pretty good as all roles are built up well for the setting, there's also a chibi mini series which just makes me want to see them in Isekai Quartet.
Final Verdict: A well written series designed to appeal to tactical warfare fans but doesn't fully translate as an anime, it's also clear that someone missed the memo on making it a harem series.
