The anime is based on the Light Novel series made by Riku Misora, and AnimeNewsNetwork describes the history as follows:
The “school sword action” story revolves around Magic Knights, modern magic-users who fight with weapons converted from their souls. Ikki Kurogane goes to a school for these Magic Knights, but he is the “Failed Knight” or “Worst One” who is failing because he has no magical skills. However, one day, he is challenged to a duel by Stella, a foreign princess and the “Number One” student. In this duel, “the loser must be obedient for life.”
