It was a time of political instability. While most of Europe was involved with power struggles, the island country of Kuchen followed its own independent path; and with the leadership of an intelligent king and his advisors, the people worked to restore their kingdom. These advisors, with strong minds and good backgrounds, were graduates of a prestigious boarding school known as the Rozenstolz Academy. Follow the lives of the five students with the potential to become the king's next advisors (known as the Strahl candidates), as they strive to achieve their dreams.
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.
Both series have a fantasy-historical setting. While both feature a large cast of handsome male characters, they don't get overly caught up in fanservice and the like, instead opting for a serious approach. Saiunkoku focuses more on romance and a female character, while Meine Liebe is more about the male characters, their friendships, and politics.
Aya, Omi, Ken and Yoji are four seemingly normal high school boys, who make up an elite assassin group known only as Weiss. The hits involve taking out corporate businessmen and corrupt politicians; however, trouble arises during a routine job, when Weiss clashes with a rival gang of assassins, Schwarz. With Schwarz in the way, they will reach the limits of their elite skills while trying to defeat their ultimate target: the Takatori family...
It is difficult to pin down exactly what makes Weiss Kreuz and Meine Liebe so similar since one deals with hitmen in the modern world while the other takes place in a academy in a vaguely historical setting but they share a certain atmosphere. The almost all male ensemble that has to interact and cooperate in close quarters as well as the contrasting personalities add an air of drama, the characters' backgrounds that are brought to weight on the narrative and the overall feeling make these titles reminiscent of each other. Those who were able to turn a blind eye to the flaws of one are likely to enjoy the other.
For the young women at the Lillian private school for girls, nothing is more prestigious than Rosa Sinensis, Rosa Gigantea, and Rosa Foetida, the beautiful and talented women who head the student council. When a young girl named Yumi's path is intertwined with Sachiko, a successor to the council, things will never be the same for the both of them. Maria-sama ga Miteru is a quiet tale of forbidden romance, friendship, and the everyday life of a school girl.
Both Meine Liebe and Maria-sama ga Miteru focus on an almost single gender cast (boys in Meine Liebe and girls in Maria-sama ga Miteru) attending a private academy, and the (supposedly, in some cases) prim and proper students that attend it. Meine Liebe focuses more on politics and dueling than Maria-sama ga Miteru, but both still have the ranking and social status pretenses in them. Both also use foreign language and concepts in them (German and French, respectively), and have hints at shoujo or shounen-ai at times. Both are very character driven, dramatic series - if you liked one, be sure to check out the other.
The country of Gazth-Sonika has been engaged in a civil war for more than a decade, struggling to stay afloat amidst attacks from the anti-government faction known as Garza. With lies and corruption seeping into the political food chain, a mysterious book in one young girl’s possession may be the only key to uncovering the truth and bringing an end to the war. This book, however, is sought by many. And when the invincible agent Madlax is hired to protect those in search of its truth, Gazth-Sonika dispatches a ruthless soldier to make sure that truth stays in the darkness...
Ouran High is a school for the extremely wealthy or, in Haruhi's case, the extremely talented. But no amount of talent will help when Haruhi accidentally drops an eight million yen vase in a music room. The vase was the property of Ouran High School Host Club, a group of attractive young men who, for a fee, provide their time and affections for their lovesick clientele: the female students. Fascinated by this strange new specimen, a poor and clumsy commoner, they force Haruhi to work for them until the debt is repaid; but they get a lot more than they bargained for...
Both series focus on an exclusive "group" of rich boys at an elite boarding school. Meine Liebe is more serious and Ouran is definitely more of a comedy, but if you like one you should find the other enjoyable, even if only for the fact that both of these "groups" are made up of "attractive" characters.
