Attack on Titan Part 1

The man-eating humanoids called Titans first appeared over 100 years ago, devouring humans without motive or remorse. What was left of mankind retreated behind three enormous concentric walls. After a century of relative peace, a young boy named Eren is growing restless. He dreams of one day seeing the world behind the walls. But on the day he and his friends Armin and Misaka decide to investigate the great and mysterious wall that keeps them penned in like cattle, a titan larger and fiercer than any that have been seen before breaches the wall, kicking a large hole through the base of it. Now, titans are flooding the city, consuming much of the surviving human population. Eren and his surviving friends enlist to fight against the insatiable monsters. The future looks bleak, but there’s more to Eren than meets the eye: he may be humanity’s last hope against extinction.
