"Walls of Hope, Wings of Freedom”( Season 01 ).

The walls had always stood, towering and unshakable, guardians of humanity’s fragile hope. To those born inside them, they were both prison and sanctuary — a reminder of weakness and a shield against extinction. For Eren Yeager, a boy of burning spirit and restless heart, they were chains he could not bear. While others accepted the walls as protection, Eren saw them as cages. His eyes, sharp with fire, longed for the world beyond, the vast unknown swallowed by Titans.

But on that fateful day, the world shattered.

The Colossal Titan appeared in a thunder of steam and lightning, its massive face rising over Wall Maria like a nightmare reborn. In a single kick, the unthinkable happened: the wall, once thought eternal, crumbled. The ground shook, the air filled with ash, and the lives of thousands were swallowed in chaos. Among them was Eren’s world — his home, his mother.

Pinned beneath the rubble, his mother’s final smile seared into his soul, Eren screamed as she was devoured by a Titan. It was not merely grief that filled him; it was rage, raw and consuming. In that moment, the boy’s heart forged an oath that would shape his destiny: to slaughter every Titan until none remained.

That vow burned brighter than his tears.

The fall of Shiganshina forced survivors into the inner walls, carrying hunger, despair, and bitter resentment. Yet for Eren, Mikasa, and Armin, it lit a path — the path of soldiers. They enlisted in the Cadet Corps, swearing blades and blood to humanity’s fight. Training was brutal, but Eren’s determination was unbreakable. While others wavered, he endured falls, bruises, and failures, his eyes fixed on one truth: strength was the only path to freedom.

Mikasa stood as his unshakable shadow — protector, sister, and silent guardian. Armin, though frail in body, shone with a mind sharper than any blade. Together, they became more than cadets; they became the remnants of Shiganshina’s dream, a trio bound by loss and fire.

But no training could prepare them for what lay beyond the gates.

When humanity launched its desperate mission to reclaim Trost, Eren stepped onto the battlefield for the first time. The reality was merciless — comrades crushed, devoured, erased in an instant. Titans were not simply monsters; they were fear incarnate. Yet Eren did not falter. His heart surged with vengeance, and his blade found flesh.

Until fate struck.

In a single moment of sacrifice, Eren threw himself to save Armin, only to be swallowed whole by a Titan’s jaws. To his friends, he was gone — another name carved into tragedy. To humanity, he was a symbol of how fragile hope remained.

But within darkness, something stirred.

From the Titan’s belly, a power long dormant awakened. Flesh tore, bones snapped, and the world trembled as Eren was reborn — not as prey, but as predator. He emerged not as a boy, but as a Titan himself, his rage manifest in colossal muscle and fire. No one could understand it. Fear and suspicion spread faster than courage. Was he human? Was he monster? Even his closest allies struggled to see past the terror of what he had become.

Yet when the walls of Trost stood on the brink of collapse, it was Eren — half-man, half-Titan — who bore the burden of salvation. With his newfound power, he moved a massive boulder to seal the breach, halting the Titans’ invasion. In that moment, humanity glimpsed something they had long forgotten: hope.

But hope came with a cost.

Eren was placed under watch, treated as both savior and threat. The military quarreled over his fate — execution or weapon. It was in this crucible of suspicion that Commander Erwin Smith and Captain Levi emerged, men who saw beyond fear into possibility. With their guidance, Eren was given a chance: to join the Survey Corps, humanity’s only line of offense beyond the walls.

And so, the journey continued.

Beyond the walls, Eren faced not just Titans, but truths hidden in shadow. The Female Titan appeared — swift, ruthless, and cunning, unlike any enemy before. It slaughtered without mercy, tearing through soldiers with terrifying intelligence. Yet Eren, driven by his vow, confronted it head-on.

The battles were not just against Titans, but against despair itself. Comrades fell, blood stained the forests, and hope once more wavered. Still, the Survey Corps pressed on, uncovering fragments of the greater mystery — that Titans were not merely beasts, but once human.

And with each revelation, Eren’s vow deepened.

By the end of that season of blood, humanity stood shaken but unbroken. Shiganshina was lost, but Trost stood. The Survey Corps had survived, though scarred by betrayal and death. And Eren, once a powerless boy staring beyond the walls, had become the keystone of humanity’s survival — the wielder of a Titan’s power, the bearer of impossible responsibility.

But in his heart, the vow remained unchanged.

The walls were not salvation. They were cages. The Titans were not undefeatable. They were enemies. And Eren Yeager, with fire in his veins and fury in his soul, would not stop until every Titan lay in ruins.

For beyond fear, beyond despair, there waited only one truth:

Humanity must fight — or be devoured.
