Mahouka Koukou no Rettousei Shizoku Kaigi-hen (魔法科高校の劣等生 入学編) is the manga adaption of the 'Master Clans Conference Arc' from the 17th to the 19th light novels.

The year is 2095. Magic has been tamed as another form of technology, and the practice of magic is now a rigorous discipline. 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!
