Brother and sister Tatsuya and Miyuki Shiba are just about to start their first year at the renowned First Magic High School of Japan. But the school's ironclad rules mean that the brilliant Miyuki enters the prestigious Course 1, while her older brother, Tatsuya, is relegated to Course 2—and that's just the beginning of their troubles!
