Attack on Titan

In a world where humans were on the brink of extinction, a small percentage of the population managed to survive by retreating behind a series of extremely high walls, taller than even the largest of their monstrous predators: the Titans. These towering beings, typically several stories high, seem to have no intelligence and devour humans for pleasure rather than sustenance. After over a century without a Titan sighting in the southern district of Shinganshina, a horrific event unfolds when a 60-meter Titan breaches the outer wall, unleashing a flood of smaller Titans into the city. Witnessing the tragic aftermath, teenage boy Eren and his foster sister Mikasa are left to pick up the pieces, with Eren vowing to wipe out every last Titan and exact revenge for humanity.
