Attack on titan - the beginning box set

In this post-apocalyptic sci-fi story, humanity has been devastated by the bizarre, giant humanoids known as the Titans. Little is known about where they came from or why they are bent on consuming mankind. Seemingly unintelligent, they have roamed the world for years, killing everyone they see. Collecting the first four volumes of the phenomenally successful Attack On Titan in a slipcased edition, this is the perfect introduction to the brutal and immersive world of the Titans.
