Fullmetal Alchemist: The Invariance of a Story Deciphered from the Law of Equivalent Exchange
1. Overview
More than a decade has passed since the serialization ended, and twenty years have passed since its birth. In a modern society where the speed of information consumption is accelerated to the limit and content that was popular yesterday is relegated to the oblivion of tomorrow, the story of "Fullmetal Alchemist" (hereinafter referred to as FMA) continues to shine with an additive brilliance rather than fading. Why does this work transcend borders and generations, "shaking the soul" as Romi Park, the voice of Edward Elric, described it? Seeking the reason solely in "nostalgia" or "perfection as entertainment" is insufficient.
The purpose of this paper is to dissect the significance of the "redefinition" presented by this work, which has achieved the monumental feat of 80 million copies in circulation worldwide, on the occasion of its 20th anniversary, with the cold perspective of a cultural phenomenon analyst and the passion of a storyteller. In an era of advancing digitalization where all phenomena are governed by algorithms and efficiency, the "Law of Equivalent Exchange" depicted by Hiromu Arakawa, its limitations, and the ethical choices that lie "beyond" it can serve as a catalyst for the challenges of technical ethics and the loss of humanity that we face today.
Fullmetal Alchemist: Work Status and the 20th Anniversary Trajectory
Cumulative Circulation: Over 80 million copies of the series in circulation worldwide (the highest record for Square Enix).
20th Anniversary Event: "Fullmetal Alchemist Exhibition RETURNS" (held in Tokyo and Osaka). Over 300 original manuscripts and drawings, figure prototypes based on key visuals, and valuable materials from the anime version were gathered in one place.
Media Development: Continued multi-layered media mix including two TV anime series, two animated films, a live-action film, stage plays, and the new smartphone game "Fullmetal Alchemist MOBILE".
Enduring Influence: The brand value continues to be maintained and expanded even after the end of serialization, such as with the 2017 live-action film adaptation and the 2023 stage adaptation.
In this paper, I will first present an abstract that logically organizes the structure of this work, and then delve deeply into the resonance of the story, its technical system, and the design philosophy of the protagonist, Edward.
2. Abstract
This report analyzes the invariance of the narrative structure of Hiromu Arakawa's manga "Fullmetal Alchemist" from technical and sociological perspectives. The analysis focuses on three points: the fictional physical and ethical system of the "Law of Equivalent Exchange" within the work, the deep psychology of "trauma and conflict" held by the characters, and the impact of "multi-layered villains" that eschew simple good-versus-evil on modern society. The results of the investigation reveal that the "growth model involving self-sacrifice" presented by this work and the "ethical boundaries" set against a sense of technical omnipotence function as a redefinition of humanity in the AI era. This work transcends the framework of mere entertainment and has established its value as a "spiritual foundation" for surviving in modern society.
3. Introduction: The Resonance of the Story—Why Do We Seek "Steel" Again Now?
"The feeling of having stepped into the world of FMA itself." This statement made by Romi Park, the voice of Ed, at the venue of the 20th Anniversary Exhibition "RETURNS" perfectly captures the emotion that fans hold for this work. Over 300 original manuscripts were displayed. In them, the overwhelming obsession Hiromu Arakawa poured into the tip of her pen and the energy of her brushwork, which seemed to scrape the paper, remained at the same temperature. Park smiled as she shared the anecdote of buying out the Colonel Roy Mustang "Rain (Candy) Day Useless Candy" at the merchandise corner, showing her deep love for the work, but behind that approachability, a sense of awe for the "resolve" emitted by the original drawings always drifted.
Why are we drawn back to the story of "Steel" so strongly? It is because the existence of a boy named Edward Elric, who bore the heavy burden of being a "State Alchemist" at the young age of 12 and continued a journey that felt like crawling on the ground to regain his "brother's body" lost through his own mistake (human transmutation), is so incredibly sincere. His red coat is a crimson reminiscent of the Philosopher's Stone, yet underneath, he wears "black" clothing to hide the oil stains from maintaining his automail. This design encapsulates his way of life, constantly facing the gritty pain of reality while holding up his ideals.
In this "uncertain era without correct answers" that is the modern day, the words Ed utters, "Stand up and walk. Keep moving forward. You've got those fine legs, don't you?" carry a "weight" that goes beyond simple encouragement. Because they are spoken by someone who himself once sank to the depths of despair and stood up on his own despite bearing the cost of heavy steel limbs, those words shake our souls. This work is not a nostalgic keepsake. It is a philosophy in progress that makes us re-recognize "the pain of walking on one's own feet" in an age where efficiency and automation are considered virtues. In the next chapter, I will delve into the technical aspects of the backbone that supports this story of the soul—the cold and precise system design called "alchemy."
4. Systematic Analysis: Alchemy's System Design and Ethical Boundaries
What makes "Fullmetal Alchemist" unique is that "alchemy," which corresponds to the "magic" in the work, is designed like an extremely logical and systematic white paper. This is not a miracle of convenience, but a technical system based on clear "constraints" and "costs."
4.1 The Three Stages of Alchemy: Comprehension, Decomposition, and Reconstruction
Alchemy follows these three strict processes.
Comprehension: Fully grasping the atomic composition and characteristics of the target substance.
Decomposition: Breaking the bonds of matter and causing it to collapse temporarily.
Reconstruction: Remaking it into a different shape based on the grasped structural information.
When Edward transmutes weapons, he touches the floor or walls to perform the technique because he uses the "matter of the entire field" as raw material. The author, Ms. Arakawa, elevated the idea of "it would be interesting if there were magic that could pull things out of walls and ceilings" into a "technology" through these logical steps.
4.2 The Mechanics of Equivalent Exchange and the Law of Conservation of Mass
The absolute principle of alchemy is "equivalent exchange." The law of conservation of mass, which states that "nothing can be created from nothing," and the law of natural providence, which states that "the same quality can only be created from the same quality," give the story tension. What is noteworthy is the technical background regarding the "energy source" of Amestris's alchemy. The energy of crustal movement that the alchemist uses was actually restricted by the existence lurking underground called "Father," which acted as a buffer between the alchemist and the crustal energy. As a result, the fact that alchemy can be "sealed" by the will of "Father" alone becomes a major plot point in the final stages of the story due to this technical vulnerability.
4.3 Comparative Analysis with Alkahestry
In contrast, "Alkahestry," which was transmitted from the great eastern nation of "Xing," utilizes a completely different energy source.
This contrast suggests that technology evolves in completely different ways depending on its "origin" and "philosophy," giving it a depth that goes beyond mere differences in combat ability.
4.4 The 'Price' and Atrocity of the Philosopher's Stone
The "Philosopher's Stone," which is the core of the story, is called an all-purpose amplifier that ignores equivalent exchange, but its true nature is an "energy body condensed from the souls of living humans." This setting, which confronts the reader with technical ethics (the atrocity of using human lives as material) behind the sense of technical omnipotence (a stone that can grant anything), poses an extremely profound question to the reader. The reason Ed and Al vow to "return to their original bodies without using the stone" is because it means rejecting the ugliest aspect of technology, which is "consuming the lives of others to achieve one's own goals."
【Cheat Sheet】Basic Knowledge of Alchemy
Alchemy Circle: A device for activating techniques that incorporates a construction formula into a "circle" that circulates power. The circle symbolizes the circulation of power and time.

The Three Major Restrictions of State Alchemists:
Thou shalt not create humans: Adherence to ethics. There are also political reasons to prevent the maintenance of private armies.
Thou shalt not create gold: Prevention of economic chaos. An economic policy restriction to curb inflation.
Thou shalt pledge loyalty to the military: A military regulation for managing alchemists as "human weapons."
Clap Transmutation: Possible only for those who have seen the "Gate of Truth." An advanced technique where the alchemist themselves becomes the construction formula, and the joined hands serve as the alchemy circle, acting as the price.
These "logics" are not just settings, but are closely tied to the characters' "choices." In the next chapter, we will delve deeper into the design philosophy of the protagonist, Edward Elric, who struggled and grew within this system.
5. Structural Analysis: Edward Elric—The Design Philosophy of an 'Incomplete Genius'
The protagonist, Edward, is distinct from the classic shonen manga model of "striving to become the strongest through effort." Although he is a "genius" who is already close to level 100 at the start of the story, his essence is "incomplete," and he is designed as a boy who always carries a sense of "guilt."
The Symbolism of Automail
The extremely realistic insights Ms. Arakawa gained from her part-time job directing traffic at a rehabilitation center are reflected in the automail, which is the core of Ed's design. The strength of a person walking with a prosthetic leg hanging from their waist. The automail inspired by this is not just a weapon, but a device that constantly makes him re-recognize the "pain of what was lost." Oil stains are inevitable in the maintenance of automail. He chooses clothes based on black so that the dirt is not noticeable, and wears a crimson coat over them, inspired by the Philosopher's Stone. This color design expresses both his sin and his indomitable will.
Concealment and Disclosure of the Inner Self
Ed's long bangs were designed with the intention of hiding his emotions. Arakawa-san stated, "I wanted to create an atmosphere of having something to hide," and frequently used the technique of "concealment," intentionally preventing readers from reading Ed's expressions. Furthermore, his complex about his short stature had a brilliant piece of foreshadowing in the setting. In fact, his height did not increase because he was continuously sending nutrients to Al's body on the other side of the Gate of Truth. This fact proved that the bond between the brothers was not just spiritual, but connected on a biological and physical level, giving readers a profound surprise.
The Shift to "Non-Killing": A Choice That Seized the Steering Wheel of the Story
The strategic significance of this work is symbolized by Ed's determination in Episode 41: "A way to lose no one else," and "If someone is about to be sacrificed in front of me, I will protect them." Initially, Arakawa-san envisioned a hard-hitting development, even considering a path where Ed would kill people by the end of his journey. However, as the story progressed, Ed's own will began to surpass the author's intentions. The conviction that "Ed would definitely say this" caused Arakawa-san, the author, to steer the story in a new direction. This choice of "non-killing" was proof of the true "independence" of a boy who had learned to acknowledge his own ignorance, stop carrying everything alone, and rely on adults. Ed grew from a "child trying to solve everything by himself" into an "adult" who believes in a network with others.
6. Examples and Influence: Social Impact and the Trajectory of the 20th Anniversary
The paradigm shift brought about by "Fullmetal Alchemist" has extended beyond the manga world after its serialization ended, and even into the global cultural sphere.
The Multi-layering of Villains: Beyond Simple Good vs. Evil
This work also depicted thorough backstories for the enemy side, the "Homunculi." The interpretation that "evil has its own pride, different from that of humans" can be said to be the source of the method used in the later "Demon Slayer: Kimetsu no Yaiba" to depict the sorrow of the demons. For example, the ugly yet poignant inferiority complex toward humans that Envy, the embodiment of "Envy," showed at the end: "Maybe I'm the one who's envious..." Also, the cold, clear pride shown by Lust, the embodiment of "Lust." Such multi-layered villain portrayals elevated the story from a simple victory of justice to a collision of incompatible values.
Reception Overseas: Global Empathy
The reason it is enthusiastically supported in the English-speaking world as "Fullmetal Alchemist" is that while it is based on a Christian context (the Tree of Sephiroth, Nicolas Flamel, Ouroboros), it also deals with universal themes such as "historical tragedy" and the "darkness of military regimes," symbolized by the Ishval Extermination Campaign. The setting that the founding of Amestris itself was a device for the Homunculi's purpose reminded readers of colonialism and the ego of great powers in real history, giving readers around the world a sense of realistic fear and empathy.
Achievements of Media Mix and the Significance of Implementation
Anime, theatrical versions, live-action, and the smartphone game "Fullmetal Alchemist MOBILE." The key to maintaining brand value is that the "soul of the original work" is respected in all these developments. The exhibition of materials at the 20th Anniversary Exhibition "RETURNS" was a ritual for fans to confirm the "physical implementation" of paper, ink, and the pressure of the pen tip in an age of digital dominance. The details residing in every single prop, such as Colonel Roy Mustang's research book on encrypted female names, are what established this fantasy world as a "fact" in our hearts.
7. Conclusion and Future Prospects: The "Price" Beyond Equivalent Exchange
As is clear through this article, the final destination reached by "Fullmetal Alchemist" was the acquisition of humanity by "discarding the law of equivalent exchange." Edward Elric's choice after the final battle to trade his own "Gate of Truth (the ability to use alchemy)" to retrieve everything of his brother Alphonse. It is a story of ultimate rebirth, choosing warm "connections" as a human being even if it meant discarding his identity as an alchemist.
The cold equation of "equivalent exchange" reigns as a dominant logic in the modern AI era and a society where everything is quantified and automated. However, the words Winry Rockbell returned to Edward's clumsy proposal ("I'll give you half of my life, so you give me half of yours!")—"I'll give you all of it, not just half"—fundamentally overturn this logic. Human love, trust, and the heart that cares for others exist in a "gratuitous realm" that can never be quantified.
In an automated society, the strategic significance of Ed choosing "human connection (analog)" over "ability (algorithm)" is immeasurable. We acquire many "abilities" in search of efficiency, but to obtain what is truly important, we may sometimes need the courage to close those convenient "doors" ourselves.
As Romi Park said, this work shakes the soul of anyone who touches it even once and is engraved in the heart as a lifelong treasure. Even after passing the 20th-anniversary milestone, the memories of the journey Ed and Al walked, covered in mud and stained with oil, will never rust. The incalculable "love" and "will" that lie beyond equivalent exchange. When you turn those pages again, you will discover within your own heart the "steel will" that continues to shine across the ages.
