A prequel series to the number-one manga bestseller. Humanity has learned to live in complacency behind its high walls, protected from the giant Titans. But when a Titan-worshipping cult opens one of the gates, a Titan wreaks havoc, consuming the cultists. After the rampage is over, two young Survey Corps members are shocked to discover a pregnant woman's partially digested corpse—with her baby still alive inside it! What will the fate of this child of the Titans be? And how will humanity learn to cope with the Titan threat?
Angel and Xenophon's Device, meant to help humanity combat the Titans, has always confounded those who were meant to use it. But years later, after Sharle successfully brings Angel out of his underground home, he is ready to correct its fatal flaw for good. But that's only half of the problem--the Survey Corps will need a grueling new training program to make use of it!
