The original The Irregular at Magic High School light novels are written by Tsutomu Sato, illustrated by Kana Ishida and published in Japan by ASCII Media Works under their Dengeki Bunko imprint. Yen Press also publishes an English language version of the series.
Crunchyroll describes The Irregular at Magic High School:
Based on the light novel by Tsutomu Sato, The irregular at magic high school is set in a world where magic exists but instead of using chants and spells, magic users cast spells with their Casting Assistant Device (CAD). The CAD is infused with the user’s Psions (a substance-less thought particle) that activates the device and constructs the magic ritual.
The story follows Tatsuya Shiba, a bodyguard to his sister Miyuki Shiba, who is also a candidate to succeed the leadership of the Yotsuba clan, one of the Ten Master Clans that govern Japan’s magicians. They enroll into First High School which segregates its students based on their magical abilities. Miyuki is enrolled as a first course student and is viewed as one of the best students, while Tatsuya is in the second course and considered to be magically inept. However, Tatsuya’s technical knowledge, combat abilities, and unique magic techniques cause people to view him as an irregular to the school’s standardized rankings
Tatsuya Shiba (司波 達也, Shiba Tatsuya) and Miyuki Shiba (司波 深雪, Shiba Miyuki)
Tatsuya and Miyuki are siblings of the same school year and children to Tatsurou Shiba and the late Miya Yotsuba with Tatsuya being 11 months older than Miyuki; their parents had a loveless forced marriage, and when their mother died, their father married his mistress, Sayuri Furuha, leaving the siblings to live by themselves. Maya Yotsuba, their aunt and the current leader of the Yotsuba Clan, was the reason Tatsuya was born with the unique magic to decompose, reconstruct, and detonate matter (along with some gene manipulation).6Out of fear of his powers, the Yotsuba Clan leadership of that time argued for Tatsuya’s death, forcing Miya and Maya to take measures to ensure his survival: the first was Miyuki’s creation with genetic enhancements in utero, who would act as a seal to Tatsuya’s power; the second was to magically dull Tatsuya’s emotions except for his familial love towards Miyuki; and the third was to assign Tatsuya to be Miyuki’s bodyguard in order to develop his sense of loyalty towards her. During a family vacation in Okinawa, Tatsuya warded off an invasion by the Great Asian Alliance and joined the 101 Independent Magic-Equipped Battalion which is headed by Major Kazama Harunobu. At some point during his life, Tatsuya developed an interest in engineering magical technology and commercialized revolutionary technology through his family’s company, Four Leaves Technology, under the pseudonymous identity Taurus Silver. He is voiced by Yuichi Nakamura and Alejandro Saab
