In a world where magic has evolved from myth to everyday technology, the First National Magic University Affiliated High School distinguishes students into Course 1 and Course 2 based on exam performance. Siblings Miyuki and Tatsuya Shiba enroll in First High, with Miyuki excelling in Course 1 and Tatsuya placed in the less prestigious Course 2, known derogatorily as 'Weeds.' Despite this divide, Miyuki is determined to showcase her brother's exceptional magical prowess to the skeptical school, highlighting that Tatsuya is a magician of unparalleled skill. Mahouka Koukou no Yuutousei offers a fresh perspective on the events of Mahouka Koukou no Rettousei, narrated through Miyuki and other female characters in the series.
