Reference excerpt

Qualidea Code (クオリディア・コード, Kuoridia Kōdo) is a Japanese multimedia project co-published by Shueisha's Dash X Bunko imprint, Fujimi Shobo's Fujimi Fantasia Bunko imprint, Media Factory's MF Bunko J imprint, Shogakukan's Gagaga Bunko imprint, and Shueisha's Jump Square magazine. The original concept was developed by Marvelous and a three-person unit of writers known as Speakeasy made up of Kōshi Tachibana, Sō Sagara and Wataru Watari. It launched in 2015 with several light novels, and a manga began serialization in Jump Square in 2016. An anime television series, produced by A-1 Pictures and directed by Kenichi Kawamura, aired between July and September 2016.

Plot The story takes place in a world where humankind is at war against an enemy called the "Unknown". Children who were evacuated to a cold sleep facility during the invasion by the Unknown several decades ago wake up from their slumber and learn that their bodies developed supernatural abilities called "World". In order to protect Japan from the Unknown emerging from the Tokyo Bay gate, the boys and girls wage battles for the defense of the cities in the Kantō region (Tokyo, Yokohama (Kanagawa), and Chiba).

Characters

Main Ichiya Suzaku (朱雀壱弥, Suzaku Ichiya) Voiced by: Soma Saito Ichiya is the protagonist for Sonna Sekai wa Kowashiteshimae. A head student representative from Tokyo. He is a person with high confidence and thinks low of others, but probably due to him having terrible conversation skills. He shows respect to adults as older people have helped him in his childhood. It is hinted that he has romantic feelings toward his childhood friend, Canaria. Canaria Utara (宇多良カナリア, Utara Kanaria) Voiced by: Yui Ishikawa Canaria is the student representative from Tokyo and its sub-head. Canaria is Ichiya's childhood best friend who is actually a year older than him, but because she was late a year during the cold sleep, her age is now same as Ichiya. She affectionately calls Ichiya "Icchan". She is the only one whose staff can't fly, which means she has to be carried by other students whenever they engage in battle. She has romantic feelings toward Ichiya and it is hinted that their feelings are mutual. Asuha Chigusa (千種明日葉, Chigusa Asuha) Voiced by: Chika Anzai Asuha is the student representative and head of Chiba, and also Kasumi's younger sister. Kasumi Chigusa (千種霞, Chigusa Kasumi) Voiced by: Yuma Uchida Kasumi is the protagonist for Dōdemo Ii Sekai Nante. Student representative and sub-head of Chiba, he is Asuha's older brother whom she calls "Onii". He always has quarrels with Ichiya, although according to his sister this is because "he's only able to talk to people by replying in mean words", which is also why he can't stand Canaria. He usually holds the sniper position. Maihime Tenkawa (天河舞姫, Tenkawa Maihime) Voiced by: Aoi Yūki Maihime is the protagonist for Itsuka Sekai o Sukū Tame ni. Student representative and head of Kanagawa with a carefree and a bit childish personality, but is a good leader. She has godlike powers, but sometimes has no control over them. Hotaru Rindō (凛堂ほたる, Rindō Hotaru) Voiced by: Ayaka Fukuhara Hotaru is the student representative and sub-head of Kanagawa. She dotes and spoils her friend since childhood Maihime, whom she calls "Hime", too much to the point that she can't bear the moment she isn't with Maihime.

Others Aoi Yaegaki (八重垣青生, Yaegaki Aoi) Voiced by: Sora Amamiya Aoi is a student from Kanagawa who is part of the student administration. Her World is the ability to spread anything to a wide area.

Worked examples

Example 1 — a first encounter with Qualidea Code

Start with the simplest possible case. Write down what Qualidea Code claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Qualidea Code 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 Qualidea Code 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 Qualidea Code

In research: Qualidea Code appears in astronomy 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 Qualidea Code 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.
In the classroom: Qualidea Code is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2015 Japanese novels, 2016 Japanese novels, 2016 anime television series debuts, so understanding it makes those chapters shorter.
In everyday life: Look for Qualidea Code outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Qualidea Code in simple terms?

Why does Qualidea Code matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
