Centuries ago, humanity was driven nearly to extinction by colossal, humanoid monsters known as Titans, forcing the survivors to cower behind enormous concentric walls. The true horror of these giants lies in their consumption of human flesh, which seems motivated not by hunger but by pleasure. To ensure their survival, the remnants of humanity lived within these defensive barriers, enjoying a hundred years without a single Titan encounter. But that fragile peace is shattered when a Colossal Titan breaches the supposedly impregnable outer wall, reigniting the desperate fight for survival against the man-eating abominations.
After suffering a devastating personal loss at the hands of the invading creatures, Eren Yeager dedicates his life to their eradication by joining the Survey Corps, an elite military unit that battles the merciless humanoids beyond the walls. Alongside his adopted sister Mikasa Ackerman and childhood friend Armin Arlert, Eren enters the brutal war against the Titans, racing to find a way to defeat them before the last walls fall.
