In a world where humanity teeters on the brink of extinction, the remnants of mankind cower behind towering walls, seeking shelter from the monstrous humanoid creatures known as titans. These giants, driven not by hunger but by an insatiable appetite for human flesh, have slaughtered countless lives, leaving survivors traumatized and forever haunted by their presence. For a century, an uneasy peace prevailed, with no titan sightings within the confines of the concentric barriers, but this fragile calm is shattered when a colossal titan breaches the seemingly impenetrable outer wall, reigniting the desperate struggle for survival against these merciless abominations. Amidst the chaos and devastation, young Eren Yeager emerges, forever scarred by the loss of his loved ones to the invading titans. Fueled by an unwavering determination to eradicate the titans, Eren enlists in the Survey Corps, an elite military unit tasked with combating these fearsome adversaries beyond the safety of the walls. Together with his adopted sister Mikasa Ackerman and childhood friend Armin Arlert, Eren embarks on a perilous journey to uncover the secrets behind the titans' existence and find a way to defeat them before the last bastions of humanity crumble. As they face unimaginable horrors and confront the very limits of human endurance, the trio must race against time to protect what remains of their world and forge a path to a future free from the shadow of the titans.
