The Irregular at Magic High School

Mahōka Kōkō no Rettōsei is a light novel.

Plot
Magic is a product of neither legends nor fairy tales, but instead has become a technology of reality since a time unknown to people. Supernatural power became a technology systematized through magic, while magic became a technical skill. A "Supernatural Power User" became a "Magic Technician." Magic Technicians (in short, Magicians) are nurtured through Magic High Schools and Universities.
