The Final Season (S4)
About
【Season 4 Story Timeline】 ■ Marley Arc ・Marley is a military nation that uses Titans as weapons. They segregate and discriminate against Eldians in internment zones. ・They win the war against the Mid-East Allied Forces, but the development of anti-Titan weaponry threatens their military superiority. ・Marley rushes to seize the Founding Titan. ・After returning, Reiner attempts suicide due to guilt. ・Willy Tybur, head of the Tybur family, declares war on Paradis Island before the world. ・During the speech, Eren transforms into a Titan and destroys the stage. The Survey Corps launches a surprise attack and seizes the War Hammer Titan. ・During the retreat, Gabi infiltrates the airship and shoots Sasha dead. ・This operation was Eren's solo decision. The rift between him and the military becomes definitive. ■ Paradis Civil War Arc ・Eren is detained for his rogue actions. ・Eren's supporters, led by Floch, form the "Yeagerists" and expand their influence within the military. ・Zeke arrives on Paradis Island. His true goal is the "Eldian Euthanization Plan" (stripping reproductive abilities using the Founder's power). ・The Yeagerists force military officials to drink wine spiked with Zeke's spinal fluid, taking them hostage and succeeding in a coup. ・Eren violently pushes Mikasa and Armin away, causing the outward collapse of their trio. ・Gabi and Falco realize there are "ordinary people even among the enemy" on the island, shaking their values. ■ Contact with Zeke and Activation of the Rumbling ・The Marleyan army launches a surprise raid on Shiganshina District. ・Zeke transforms the soldiers who drank his spinal fluid into Titans, causing chaos. ・Gabi shoots Eren's head off, but the head touches Zeke's hand, entering the world of the "Paths." ・In the Paths, Zeke asks for cooperation with the Euthanization Plan, but Eren refuses. ・Eren speaks to the Founder Ymir, and Ymir releases her power of her own will. ・The Colossal Titans within the walls awaken, and the Rumbling begins. ・Eren declares to all Eldians: "I will exterminate every life outside the walls." ■ Final Battle ・The remnants of the Survey Corps and Marleyan warriors join forces to stop Eren. ・Annie awakens from her crystal and joins the group. ・Hange dies stalling the Colossal Titans in a solo charge, entrusting the role of Commander to Armin. ・Floch is shot dead during the battle at the port. ・Levi decapitates Zeke, fulfilling his vow to Erwin. ・Mikasa cuts off Eren's head within the Founding Titan. ・The Founder Ymir is liberated, and the power of the Titans vanishes from the world. ■ Conclusion ・Eren's true intentions are revealed after his death: he killed 80% of humanity with the Rumbling so that the friends who stopped him could negotiate peace as "heroes." ・Mikasa's choice was the key to ending the power of the Titans. ・Eren himself says he "doesn't know why he did it," suggesting it wasn't a perfectly rational plan. ・All Eldians who had become Titans return to human form. ・Armin and the others become peace ambassadors. ・In the distant future, Paradis Island is destroyed by war. ・In the even further future, a giant tree resembling Ymir's tree appears again, ending with a hint of the Titans' return.

Intro
Beyond the sea, there was not freedom, but the world.
The "outside" dreamed of within the walls was no paradise. Borders, nations, history—there, multiple walls existed in different forms. People called each other "devils" and directed hatred toward one another. That structure was no different from the one inside the walls.
On the continent, the flames of war never cease, and children compete for merit just to survive. On the island, the boy who reached the sea no longer smiles. The horizon, once a symbol of freedom, has turned into a boundary separating friend from foe.
There is no answer to who is right. However, morning comes to both sides of the sea. People think of their loved ones and stand up to live through today.
Open your eyes. Listen closely. Is it gunfire, the sound of waves, or someone's crying?—What you hear changes depending on where you stand.
Today, once again, your day begins in this world.
Example 1
A conversation when reuniting with Reiner in the basement the night before the Liberio raid. When asked why he keeps moving forward, he repeats the words Reiner once said. It's because... I was born into this world.
Right after decapitating Eren in the final battle, while kissing Eren's lips. A parting word. See you later, Eren.
The moment he showed his resolve to take over the role of Commander after Hange's death. Please... make me the Commander of the Survey Corps that fell into hell.
Right after decapitating Zeke, muttering before the visions of Erwin and his fallen comrades. Reporting that he fulfilled his promise. Are you watching...?
The final words muttered while being burned during a solo charge into the swarm of Colossal Titans. He lived his life as a Titan researcher to the end. Ah... Titans really are incredible...!
