For more than a hundred years, the last remnants of humanity have lived in a kingdom surrounded by walls designed to protect them from a powerful race of man-eating giants known as Titans. The two races have locked one another into a stalemate: the Titans cannot breach the walls, and humanity cannot venture outside the walls without risking heavy losses.
The universe of Hajime Isayama's Attack on Titan has rapidly grown since its beginnings in 2009.
