Attack On Titan Vol. 21 Limited Edition W/ Booklet

In a world where humanity has been pushed to the brink of extinction by a terrifying race of man-eating giants known as Titans, the towering city walls that had kept humans safe for over 100 years are suddenly breached by a single Colossal Titan of unimaginable size.
The intense trauma of witnessing his own mother being devoured by a Titan gives birth to an unlikely young hero—Eren Yeager, who solemnly vows to slaughter every last Titan on Earth. Together with his adopted sister Mikasa and best friend Armin, they join the military and train to join the most elite group of Titan-slayers, and, along the way, discover the unknown mysteries regarding the Titan and human races…
In Vol. 21, locked in a desperate battle against the man-eating Titans with the fate of humanity on the line, the Survey Corps gets ever closer to Eren's basement and the mysteries locked within. But to get there, they are faced with a terrible choice that will affect every human soldier…
This Limited Edition also includes a bonus booklet depicting a side story of the Survey Corps of an incident told from the characters' different perspectives.
