Attack On Titan Vol. 12

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…
“The Chase Is On!”Eren is taken by the Colossus and the Armored Titan. Will Erwin and the Survey Corp be able to rescue him without getting slaughtered?
