The man-eating humanoid giants we call "Titans" first appeared over 100 years ago, devouring humans without motive or remorse.
What was left of mankind retreated behind three enormous concentric walls. No Titans have breached the walls since, and humanity has lived in peace.
After a century of relative peace, the people within the walls are growing restless. A young man named Eren and his
friends Armin and Mikasa venture to the wall’s edge with the hopes of seeing what’s on the other side. But before
they can get there, the unthinkable happens; a Titan larger and more fierce than any that have been seen before
breaches the wall, kicking a large hole through the base of it.
Now, a once isolated world is flooded with seemingly indestructible Titans, and the only way to beat them is to fight back.
But the military forces Eren joins to protect humanity appear to be protecting some secrets of their own. The future looks
bleak, but there’s more to Eren than meets the eye: he may be humanity’s last hope against extinction.
