Reference excerpt

Nobunaga the Fool (ノブナガ・ザ・フール, Nobunaga za Fūru) is a Japanese stage play and anime series, part of a wider franchise titled The Fool by anime creator Shōji Kawamori. The play is a combination of live actors produced by Avex Live Creative and animation by Satelight, first performed on December 8, 2013.

Plot Once upon a time, there were two planets called the Western Star and the Eastern Star. The two sides were bound by the "Dragon Vein" spanning the heavens. The civilization that once had prospered has now turned to a tale of dreams, as the inextinguishable flames of war tear the realm asunder. The two planets remain engulfed in endless battles. The return of the super technology known as "Sacred Treasures" could revolutionize the world order, but no one knows of them but one person—a "heretical girl". A girl from the Western Star, Joan Kaguya d'Arc, saw divine revelations of the birth of a "Savior King" who will save the world. She embarks on a journey to the Eastern Star with Leonardo da Vinci, "the one who observes the world". They come across the heretic of the Eastern Star and "the greatest fool of the day", Nobunaga Oda.

Characters

Main characters Nobunaga Oda (オダ・ノブナガ) Voiced by: Mamoru Miyano (Japanese); Scott Gibbs (English) Nobunaga is the main character and a member of the Oda Clan in the Eastern Star. He is usually taken as a fool for his brash and impulsive behavior, thus both his father and the court claim that his brother Nobukatsu would be a better successor to his father. He obtains powerful Giant Battle Armor from Da Vinci, naming it "The Fool" in homage to his reputation. He is prophesied by Joan to be the Savior King that will unite both the Western and Eastern Stars. He chooses to become the Destroyer King and faces and is killed by his retainer Mitsuhide. However, against all prognostic, what he destroys is not the creation itself, but the power of destruction instead, and becomes the avatar of chaos. Before dying, he declares his love for Joan, and vow to encounter each other in their next lives. Joan Kaguya d'Arc (ジャンヌ・カグヤ・ダルク, Janne Kaguya Daruku) Voiced by: Yōko Hikasa (Japanese); Juliet Simmons (English) Joan is introduced as a woman ostracized from the village Domrémy who is guided by divine revelations of an ominous future for the Western Star. She meets Da Vinci and joins him in his journey to the Eastern Star, where she meets Nobunaga and disguises herself as a male retainer called Ranmaru Mori to fight by his side. She possesses the Sacred Treasure of Absolute Purity, one of five powerful amulets that can empower a Giant Battle Armor. She frequently has doubts as to Nobunaga being the Savior King, claiming she will never understand him. Eventually, she receives her own Giant Battle Armor from Da Vinci, naming it Orléans. She appears to be developing slight feelings for Nobunaga, as evidenced by her jealousy during the betrothal ceremony between Nobunaga and Himiko. She admitted her love for him later on while conversing with Himiko. She is fatally injured during the final fight and remains with Nobunaga, even after he becomes the King of Destruction, until both die, while declaring their love for each other and vowing to meet in their next lives. Mitsuhide Akechi (アケチ・ミツヒデ) Voiced by: Takahiro Sakurai (Japanese); Mike Yager (English) Mitsuhide is one of Nobunaga's retainers who is extremely calm and collected. He is Nobunaga's chief political advisor and the master of the Oda Clan's shinobi forces. A kind man despite his quiet demeanor, he reluctantly assassinated Nobukatsu in order to ensure that Nobunaga succeeds the clan. He seems to have feelings for Ichihime, evidenced by the fact that he felt shocked when Caesar proposed to her. He is brainwashed by Arthur, and comes to believe that Nobunaga is the King of Destruction and tries to kill him in order to save the world. After Arthur is killed, he chooses his own path and kills Nobunaga, while realizing that he is the true Savior King and vows to Nobunaga and Joan that he will create a world of peace. Hideyoshi Toyotomi (トヨトミ・ヒデヨシ) Voiced by: Yūki Kaji (Japanese); Greg Ayres (English) Hideyoshi is another one of Nobunaga's retainers who is hyperactive and vulgar, which earned him the nickname "monkey". He has shown to be proficient with machinery and is capable of great acrobatic feats, implying training in the shinobi arts. He eventually steals his own Giant Battle Armor from the Western Plant, which he named Goku, and is given the Sacred Treasure of Wind by Nobunaga. After being nearly killed by Alexander, he becomes part cyborg after being saved by Himiko's powers. He is the only person that knows that Mitsuhide killed Nobukatsu, after being told by the former. Leonardo Da Vinci (レオナルド・ダ・ヴィンチ, Reonarudo Da Vinchi) Voiced by: Tomokazu Sugita (Japanese); David Wald (English) Da Vinci is a genius inventor from the Western Star. He is the one who builds "The Fool" and entrusts it to Nobunaga. He usually provides guidance to Joan and others by giving tarot card readings. He came to Joan in her village and travels with her to find out the meaning behind her divine revelations and to find the "truth" of the world. After ending his painting The Last Supper, he dies after finally understanding the truth of the world, while letting all his tarot cards fly away.

Worked examples

Example 1 — a first encounter with Nobunaga the Fool

Start with the simplest possible case. Write down what Nobunaga the Fool 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 Nobunaga the Fool 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 Nobunaga the Fool 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 Nobunaga the Fool

In research: Nobunaga the Fool 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 Nobunaga the Fool 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: Nobunaga the Fool is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2013 plays, 2014 anime television series debuts, Action anime and manga, so understanding it makes those chapters shorter.
In everyday life: Look for Nobunaga the Fool 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.
