In the inaugural season, viewers are introduced to Orpherus, Eduard, Camus, Lui, and Naoji, five noble students enrolled at the esteemed Rozenstolz academy in the European realm of Kuchen. These youths belong to the Strahl class, grooming them for future advisory roles in the royal court. Amidst their studies, they navigate treacherous waters filled with corrupt officials, clandestine operatives, assassination plots, and power-hungry foes that jeopardize the nation's stability and even the monarch's life. Into this volatile mix steps Isaac, an English author whose presence adds another layer of complexity to their already tumultuous world.
