Attack on Titan (2022) Plot Summary Explained

Eren starts the Rumbling as a radical attempt to break the inherited cycle of hatred and war between Eldians and the outside world. Working through Ymir in the Paths, he releases the Wall Titans so they will march beyond Paradis and kill the population outside the island. The later release of Eren’s memory blocks reveals a more calculated motive: he intended the catastrophe to spare roughly twenty percent of humanity, even though most of the world would die.

Foreshadowing: Eren’s childhood vow of revenge foreshadows the later escalation of his hatred into a willingness to sacrifice most of humanity.

Mikasa kills Eren because he has become the agent of the Rumbling and refuses to stop the genocide, despite the global coalition’s attempt to reach him. Their bond makes the choice emotionally devastating, but she treats stopping him as her duty rather than allowing personal love to determine the outcome. She decapitates him in the final confrontation, and his death ends the Titan crisis.

Foreshadowing: Mikasa’s repeated protection of Eren establishes the emotional bond that makes her final attack against him so consequential.

Eren inherited the Attack Titan from Grisha rather than creating its power spontaneously. Grisha passed that power to Eren shortly after the breach of Wall Maria, and memories of the transfer resurface during the Battle of Trost, when Eren first transforms. The later Shiganshina revelation adds that Grisha had obtained the separate Founding Titan by eating Frieda Reiss and passed that power to Eren when Eren ate him. These two inherited lines explain why Eren can access both the Attack Titan and the Founding Titan’s Coordinate.

Foreshadowing: Eren’s recovered memory of Grisha granting him power foreshadows the later Shiganshina revelation about Titan inheritance.

The Paths are atemporal gateways that connect Eldians across time and space, and they lead Eren and Zeke to Ymir Fritz, the original Titan. Ymir’s consciousness holds the Founder’s power, but it is also burdened by a tortured history that has kept her within the Paths for thousands of years. Zeke wants her to stop the Subjects of Ymir from reproducing, whereas Eren persuades her to use that power for his own design, enabling the Rumbling.

Foreshadowing: Eren’s earlier use of the Coordinate shows how one shifter can influence thousands, anticipating Ymir’s role in releasing the Wall Titans.

Eren is the last active link between the Founder’s power and the Titans, so killing him severs the source that sustains their transformation. Pure Titans revert to human form, Titan Shifters lose their abilities, and the Eldians are freed from the curse that let Marley turn them into weapons. The death therefore ends the Titans as a supernatural threat, not merely Eren’s role in the Rumbling.

Foreshadowing: The Paths reveal that Eren’s power runs through Ymir Fritz, making his death the release point for every Titan transformation.

The three walls conceal enormous, dormant Wall Titans rather than containing only defensive stonework. Their later release through the Founding Titan’s power becomes the mechanism behind the Rumbling. The discovery means the walls are part of Paradis Island’s hidden Titan infrastructure, not just barriers built to keep Pure Titans out.

The Pure Titans inside Wall Rose are transformed human beings from villages within it, not creatures that crossed the wall. Their appearance exposes the central truth that all Pure Titans are human victims of Titan transformation. This changes the Survey Corps’ understanding of the enemy from a separate species into a human-made catastrophe.

Foreshadowing: The earlier discovery of Titans sealed inside the walls establishes that Titan presence on Paradis can be hidden in places no one suspects.

The Coordinate lets Eren command other Titans, turning them from independent threats into weapons under his control. He uses it to kill the Smiling Titan that murdered his mother and to send Pure Titans after Reiner and Bertholt. The same connection to the Founding Titan ultimately helps him unleash the Wall Titans, so this power is both a tool of revenge and the mechanism of the story’s largest catastrophe.

Foreshadowing: His ability to redirect Pure Titans during the Wall Rose battle foreshadows his later ability to awaken the Wall Titans.

Reiner and Bertholt are infiltrators: Reiner is the Armored Titan and Bertholt is the Colossal Titan, both working for Marley to capture Eren and the Founding Titan. Their attempt to kidnap Eren and Ymir exposes the conflict beyond the walls, and Ymir willingly leaves with them so Historia remains out of enemy hands. Their betrayal turns the Survey Corps’ internal struggle into the opening phase of a larger conflict with Marley.

In Attack on Titan, Eren joins the military because the Colossal Titan’s attack on Shiganshina kills his mother, leaving him consumed by a need for revenge on Titans. He enlists with Mikasa Ackerman and Armin Arlert and trains to become a soldier so he can fight the creatures that destroyed his home. His early vow begins as personal revenge but eventually becomes the justification for a much larger attack on the world.

Foreshadowing: Eren’s vow after his mother’s death establishes the revenge motive that drives his later radical choices.

Grisha leaves Eren with the clue that the truth about their world is waiting in the Yeager basement, so the Survey Corps treats it as the key to explaining the Titans. Reclaiming Shiganshina is therefore not only a military objective but a way to reach the basement and uncover the island’s hidden history. The basement eventually reveals that the Eldians are an oppressed people trapped on Paradis Island rather than humanity’s last survivors.

Foreshadowing: The clue about the Yeager basement appears in Eren’s recovered memory during Trost, guiding the operation toward Shiganshina.

Historia refuses Rod Reiss’s plan because she will not help him preserve the Reiss family’s power by turning Eren into another Titan vessel. She rejects his demand that she devour Eren and smashes the serum, ending the succession scheme before it can proceed. Rod drinks the serum himself, becomes an Abnormal Titan, and is killed, leaving Historia to take the throne.

Foreshadowing: Historia’s hidden royal identity, revealed during the Wall Rose battle, foreshadows Rod’s later reliance on her bloodline.

Eren and Zeke orchestrate the raid on Liberio to provoke Marley and move Eren’s larger plan forward. During the attack, Eren kills Willy Tybur and gains the War Hammer Titan’s power by devouring Willy’s sister Lara. The strike is therefore both a direct attack on Marley’s leadership and a calculated step toward the invasion and Rumbling that follow.

Foreshadowing: Zeke’s cooperation with Eren during the Liberio operation hints that their shared strategy extends far beyond a single raid.

After Erwin Smith’s death, Levi Ackerman injects Armin with Titan spinal-fluid serum so he can take Bertholt’s Titan power. Armin then eats Bertholt to complete the inheritance, making him the new Colossal Titan. The transfer preserves the Survey Corps’ ability to confront Reiner and Bertholt, and it illustrates the two requirements for inheriting a Shifter’s power: serum and consumption.

Foreshadowing: Kenny’s serum and the possibility of inheriting a Shifter’s power are established before the Battle of Shiganshina.

After the Rumbling and Eren’s death, Paradis Island and the wider world begin rebuilding, while Queen Historia leads peace negotiations intended to prevent another cycle of war. Armin, Levi, and Mikasa are recognized as heroes, and the Titan threat disappears, but the final scenes show Shiganshina reduced to rubble in a later conflict. The ruined city and the tree on Eren’s grave create a bittersweet ending in which temporary peace gives way to another cycle of violence.

Foreshadowing: The tree planted over Eren’s grave grows into the same kind of tree associated with Ymir’s discovery, visually linking the fragile peace to the threat of renewed war.
