Attack On Titan: Part 1

One hundred years ago, the Titans appeared and devoured most of mankind without remorse. The survivors of the apocalypse retreated behind three enormous concentric walls and regrouped. After a century of peace, a larger and fierce Titan breaches the wall, allowing the other predators to run rampant. A boy named Eren is devastated when his mother is killed by the invaders and he enlists with his friends to fend off the Titans and restore stability.
