What's left of mankind has hidden in a giant, three-walled city, trapped in fear of these bizarre, giant humanoids known as the Titans. Little is known about where they came from or why they are bent on consuming humankind, but the sudden appearance of an enormous Titan is about to change everything... 

The Survey Corps is engaged in a desperate, final battle to retake Wall Maria and defeat the Titans once and for all. Eren must use his new powers to seal the holes created five years ago in the Shiganshina District gates, not to mention to finally reach the basement of his old home and find what secrets lie hidden there. But the most difficult part of the operation will be surviving whatever clever traps the Colossus Titan, Armored Titan, and Beast Titan have prepared for them! Now that Erwin is gambling with every last human life, who will triumph?
