Attack on Titan: The Anime That Made the World Uncomfortable

By Yoshi | Japan Unveiled

I want to begin with a moment that I think captures what makes Attack on Titan different from almost every other manga and anime series produced in the last twenty years.

There is a scene — I will not specify exactly where it occurs, because the location in the story matters, and I do not want to deprive anyone of arriving at it naturally — in which a character who the reader has been rooting for, who has been established as a protagonist whose values we share, does something that is genuinely evil. Not evil in the comic-book sense — not the villainy of a person whose badness is established from the beginning and serves as a narrative obstacle. Evil in the specific sense of a person whom we understand, whose reasoning we can follow step by step, whose conclusion we can see the logic of — and who, from that logic, commits an act that we cannot excuse.

The reader’s response to this scene — if they have been paying attention to everything that led to it — is not simple. It is not the clean horror of watching a villain do something villainous. It is the more complicated horror of watching someone you understood make a choice you cannot forgive, and finding that your understanding of them does not dissolve in the face of the unforgivable act. They are still comprehensible. That is what is horrible.

This is what Attack on Titan does at its best. And it does it consistently, across 139 chapters, in a work that is genuinely unlike anything else in mainstream manga.

What Attack on Titan Is: The Premise and Its Deceptions

Attack on Titan — Shingeki no Kyojin in Japanese — is a manga by Hajime Isayama, published in the monthly magazine Bessatsu Shōnen Magazine from September 2009 to April 2021. The anime adaptation, produced by Wit Studio for the first three seasons and by MAPPA for the final season, ran from 2013 to 2023.

The premise: humanity lives inside concentric walls, protected from giant humanoid creatures called Titans that devour humans without apparent motivation. One day, the outermost wall is breached by two abnormal Titans — a Colossal Titan of unprecedented size and an Armored Titan — allowing the smaller Titans inside. In the chaos of the breach, the protagonist Eren Yeager watches his mother consumed by a Titan.

Eren enrolls in the military, vowing to kill every Titan on earth. His best friend Mikasa — the most physically gifted soldier of their generation — and his other best friend Armin — the most strategically gifted — join him. They graduate, join the Survey Corps (the branch of the military that ventures beyond the walls), and begin the process of discovering that the world outside the walls is nothing like what they were taught to believe.

This is the premise as stated. The premise is a deception.

Not a dishonest deception — everything in the premise is accurate. But the premise describes the first quarter of the story as though it were the whole story. What Attack on Titan becomes, across 139 chapters, is something that the premise does not prepare you for and that I cannot describe without spoiling. What I can say is this: by the midpoint of the series, every assumption established in the first quarter has been overturned, and the story has become something structurally and thematically different from the post-apocalyptic action manga the premise implies.

The Walls: A World Designed to Deceive

The world-building of Attack on Titan operates on two levels simultaneously — the level of what the reader is told, and the level of what is actually true.

The society inside the walls is stratified. The Military Police, who protect the King and maintain order in the interior, are the most privileged branch. The Garrison, who maintain the walls, occupy a middle position. The Survey Corps, who venture beyond the walls into Titan territory, are the least valued and most dangerous posting — the branch where idealists and people with nothing to lose end up. The political structure — a monarchy, a church, various power factions — is established in the background before becoming central to the story.

The Titans themselves are the first deception. They appear, in the opening of the series, to be simply monsters — mindless predators whose only purpose is to consume humans. This is what the characters believe. This is what the reader believes. The process of discovering that this belief is wrong — that the Titans are something else, that their origin is something specific and something that changes the moral structure of the entire conflict — is the central narrative engine of the series’ first half.

The revelation of the Titans’ true nature is one of the most effective plot revelations in recent manga. It is effective not because it is surprising — though it is surprising — but because, in retrospect, the evidence for it was present throughout. Isayama planted the information that makes the revelation coherent across the first half of the series, in ways that reward re-reading and that make the series feel, in retrospect, exactly as deliberately constructed as it is.

Isayama’s Achievement: The Moral Architecture

The specific achievement of Attack on Titan that distinguishes it from other ambitious manga — that makes it, I think, the most morally serious mainstream manga of its generation — is the consistency and rigor of its moral architecture.

Most manga, when it introduces moral complexity, introduces it in the form of sympathetic villains — antagonists whose backstory explains, if not excuses, their actions. This is a legitimate and effective technique. Demon Slayer uses it. One Piece uses it with considerable sophistication. The sympathetic villain creates moral texture without requiring the reader to revise their fundamental understanding of who the heroes are.

Attack on Titan does something harder. It requires the reader to revise their fundamental understanding of who the heroes are.

The characters the reader has been rooting for — Eren, Mikasa, Armin, the Survey Corps — are not simply heroes. They are people with specific perspectives, specific cultural formations, specific limitations of understanding that their position inside the walls has produced. The people they fight against are not simply villains. They are people with their own specific perspectives, their own legitimate grievances, their own coherent reasons for doing what they do.

This does not mean that all positions are equally valid. Attack on Titan does not collapse into relativism — there are genuine moral distinctions between characters, genuine differences in the amount of harm they choose to cause and in their willingness to acknowledge the harm they cause. But the distinctions are not simple, and the series refuses to let them be simple.

The most demanding thing the series asks of its reader is to maintain simultaneous moral evaluation of characters they care about — to hold the complexity of caring for someone while acknowledging the wrongness of what they do. This is the kind of moral work that good literature asks of its readers. It is unusual in manga.

Eren Yeager: The Most Controversial Protagonist in Anime

Eren Yeager is the most contested protagonist in recent anime history, and the contestation is productive — it is the evidence that the series is doing what it set out to do.

In the series’ first act, Eren is a conventional shonen protagonist — passionate, determined, driven by rage at the Titans and grief for his mother. He is not particularly interesting as a character in this phase; his function is to propel the plot forward and to give the reader a point of identification for the action sequences.

In the series’ second act — as the mysteries of the world outside the walls begin to be revealed — Eren begins to change. The change is gradual and internally coherent. Each revelation about the world’s true nature, each loss he experiences, each confrontation with the gap between what he was told and what is actually true — these accumulate and produce, slowly but perceptibly, a different person than the one the reader met at the beginning.

By the series’ final act, Eren is not recognizable as the protagonist of the first act. He is someone else — someone who has thought through his situation to a specific conclusion and who pursues that conclusion with a totality of commitment that admits no revision. Whether this transformation constitutes character growth or character destruction, whether Eren at the end is the fullest expression of who he always was or a distortion of it, whether the reader should mourn him or condemn him — these are the questions that the fandom has been debating since the final arc began and will continue debating.

The debate is the point. Isayama created a protagonist whose trajectory forces the reader to examine their own moral commitments. What do you do with a character whose early self you loved and whose later self you cannot excuse? How do you hold both versions simultaneously? What does the gap between them tell you about the conditions that produced it?

These are not trivial questions. They are the questions that good literature asks. Attack on Titan asks them in the form of shonen manga, which is unusual and, I think, admirable.

The Historical Resonances: What the Series Is Actually About

Attack on Titan contains historical resonances that have been widely discussed and that require honest acknowledgment.

The visual design of the series — the militarism, the imagery of marching soldiers, the specific propaganda aesthetics of the Marleyan empire — draws explicitly on World War Two imagery, and particularly on the imagery of European fascism. This is not subtle. The uniform designs, the political structures, the relationship between the Marleyan state and its Eldian subjects — all of it is visually and structurally reminiscent of specific historical realities.

The Eldian people — the ethnic group within the Attack on Titan world who have been persecuted by Marley, forced to wear armbands identifying their ethnicity, confined to specific zones — are read by many commentators as an allegory for Jewish people under Nazi occupation, among other historical parallels. This reading is supported by the text. It is also complicated by the text — the Eldians have their own history of imperial violence, their own specific relationship to the powers that the series depicts, that resists simple allegory.

The series has been criticized in some quarters for what critics see as an ambivalent relationship to its own historical resonances — for using the imagery of historical atrocity as narrative material in ways that may aestheticize rather than interrogate it. These criticisms are worth engaging with seriously rather than dismissing.

What I can say is that the series’ engagement with its historical material is more consistent than these criticisms acknowledge. Attack on Titan does not glorify the violence it depicts. It shows the cost of violence consistently and specifically — in bodies, in trauma, in the psychological damage that perpetrating and witnessing violence produces. The final arc, in particular, is a sustained meditation on the futility of cycles of violence and the specific horror of what it looks like when someone tries to break those cycles through more violence.

Whether the series fully succeeds in what it is attempting is a question that reasonable people can disagree about. That it is attempting something — that it has a genuine argument to make about violence, about history, about the relationship between suffering and the drive to cause suffering — seems to me beyond reasonable doubt.

The Final Arc: The Most Debated Ending in Recent Manga

The final arc of Attack on Titan — specifically the final chapters that conclude the series — has generated more discussion, more disagreement, and more genuine critical engagement than the ending of any other manga I can recall in the past decade.

I will not describe the ending in detail, for the usual reasons of not wanting to deprive anyone of experiencing it directly. What I will say is that the ending makes choices — specific, consequential choices about where the characters end up and what the series’ ultimate argument is — that some readers find brilliantly consistent with everything that came before and that other readers find unsatisfying in specific ways.

Both responses are legitimate. The ending is genuinely ambiguous in ways that are productive rather than simply evasive. The ambiguity is the argument: the series is not interested in offering a clean resolution to the questions it has raised, because those questions — about violence, about cycles of history, about what human beings are capable of and what they are capable of becoming — do not have clean resolutions.

The fandom’s response to the ending has been, accordingly, divided and sustained. Years after the manga’s conclusion, the debate about the final chapters continues. This is the appropriate response to a work that was genuinely asking something of its readers rather than simply entertaining them.

The Anime Adaptation: A Decade of Visual Ambition

The anime adaptation of Attack on Titan is, across its full run, one of the most visually ambitious television anime series produced in the past two decades.

The first three seasons, produced by Wit Studio, established the series’ visual language: the ODM (Omni-Directional Mobility) gear sequences — the Survey Corps swinging through landscapes on cables, fighting Titans in three dimensions — are some of the most inventively choreographed action sequences in anime, using the specific freedom of the animation medium to create action that could not exist in live action.

The fourth and final season, produced by MAPPA after Wit Studio declined to continue, represents a different approach — more restrained, more interested in the political and interpersonal drama of the final arc, less reliant on the kinetic action sequences that defined earlier seasons. The change was controversial among fans who preferred the Wit Studio aesthetic. It was also, I think, appropriate to the material: the final arc is not primarily an action story, and the visual approach that served the earlier seasons’ action emphasis would not have served the final arc’s more static, more interior drama.

The animation of specific key sequences — particularly in the final season — is as high quality as anything produced in contemporary anime. MAPPA’s production, despite the difficult conditions under which it was made (the studio’s production schedule was reported to be extremely demanding), produced work of genuine visual ambition.

Should You Watch It?

Yes. With specific caveats.

Attack on Titan is not comfortable entertainment. It is genuinely violent, in ways that are not gratuitous but that are also not flinched from. It is emotionally demanding, in ways that some viewers will find rewarding and others will find exhausting. And it requires attention — the world-building and the narrative complexity reward careful viewing and punish distracted viewing.

If you are prepared for these conditions, Attack on Titan is one of the most rewarding anime series produced in the twenty-first century. It is the series that most completely demonstrates what the medium is capable of when it takes its own moral and narrative ambitions seriously.

Begin with the anime. The Wit Studio first season is among the finest single seasons of television anime ever produced, and it will tell you within a few episodes whether this is something you want to continue. Most people who begin it continue it.

The world inside the walls is not what it appears to be. Neither is the story being told within it.

Pay attention. Everything is connected. And by the end, you will have opinions.

That, I think, is exactly what the series was designed to produce.
