Eduard, Camus, Ludwig, Naoji and Orpherus have returned to Rosenstolz Academy after a brief holiday, but things are different in the familiar setting. A new principal is at the helm, and he has plans to change the school in ways that may not suit each student’s tastes. At the same time, Europe is preparing for war, and the proud students are trying their best to become Strahl to serve their country. Honor and righteousness are at stake; who will win this elaborate game of chess?
In an ancient and mythological land called Saiunkoku, the people have begun to recover from a period of war and famine; thus, when an official from the imperial court offers the impoverished and beautiful Shuurei more money than she could ever dream of in return for a favor, she jumps at the chance. What she doesn’t count on, however, is being asked to become a concubine to the recluse Emperor and help him transform into a better leader. What’s more, the Emperor shows little intelligence, seems to have no interest in ruling, and is rumored to prefer men. One thing’s for certain: Shuurei has her work cut out for her!
Both series are historical and political in which the main characters want to achieve power to help make their country a better place but on their path they will meet people who will try and stop them. So if you liked one, you'd surely like the other.
