Mahou Shijou Gakuin no Kishi: Mahou Tekisei Zero no Makenzukai

In a world where magic has replaced the era of knights, a magic academy named Elfina grants special status to those with magical abilities. Zero Antarc, a knight class student who cannot use magic and is naturally classified as a Shirogami, faces daily prejudice. He becomes involved in a conflict with a student from the magic class, who mocks his lack of magical knowledge.
