Reference excerpt

The Irregular at Magic High School (Japanese: 魔法科高校の劣等生, Hepburn: Mahōka Kōkō no Rettōsei; lit. "The Poor Performing Student of a Magic High School") is a Japanese web novel series by Tsutomu Satō.

The story takes place in the 2090s decade of Japan where technology has allowed magic to exist, and follows Tatsuya and Miyuki Shiba, siblings who enroll into the First High magic high school. They attempt to live their daily lives in peace while keeping their connections to the infamous Yotsuba clan secret, but Tatsuya is shunned for his apparent ineptness while Miyuki attracts attention for her magical abilities. In 2013, each story arc received a manga adaptation with varying manga artists and publishers. That same year, an anime television series adaptation by Madhouse was announced, and aired from April to September 2014. The Irregular at Magic High School franchise has been localized for English by two companies; the light novels and one of the manga adaptations are licensed by Yen Press, while Aniplex of America licensed the anime series.

Synopsis

Setting The series is set in a world with an alternate history, where magic exists and has been refined through modern technology. However, the ability to use magic is determined by genetics, limiting the number of magicians in existence. Following a 20-year long Third World War that reduced the world's population to 3 billion, the world's superpowers have shifted to four nations: The United States of North America (USNA), the New Soviet Union, the Great Asian Alliance, and Japan. In Japan, the magic community is informally governed by the Ten Master Clans in lieu of the government. Due to the limited number of magicians, they are treated as a commodity and forced to enter magic-related schools and professions. Nine magic high schools exist in Japan; they each specialize in different aspects of magic and are simply referred to by their numbers.

Plot 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. They enroll into First High which segregates its students based on their magical abilities. Miyuki is enrolled in the first course and viewed as one of the best students, while Tatsuya is placed 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.

Worked examples

Example 1 — a first encounter with The Irregular at Magic High School

Start with the simplest possible case. Write down what The Irregular at Magic High School claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Irregular at Magic High School before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Irregular at Magic High School ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Irregular at Magic High School

In research: The Irregular at Magic High School appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses The Irregular at Magic High School in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
