The event manga of 2012, the most exciting and overwhelming action shonen of recent years, awarded in its homeland with the prestigious Kodansha award for "best manga for boys". A giant that appears out of nowhere, destroying the city walls. That day, humanity remembered the terror of being controlled by them... the humiliation of living like birds in a cage. It all happened 107 years ago. The entire human race... except for a few... was devoured by the giants. All those people ended up directly in the stomachs of those beings. That's how our ancestors thought of building enormous walls that the giants could never cross. They managed to create a territory safe from the threat of the giants, but... that was up until five years ago. But now it's our turn, the humans. From now on... we will be the ones to devour the giants! Now, finally, the human race can take back its dignity. We can win. For humanity, it's time... to attack!
