Erika Klause, who has been separated from her brother when she was little, decided to enter Rosenstolz Academy (in Germany), where she was sure to see him. But what she encounters at first day of school is the five Strahl (King scholars) candidates, and three new girl friends, as well as tons of rumor-mongering classmates xD. What could possibly go wrong at finding a long-lost brother in an exclusive school?
Yuki Kaori did the original character designs.
