Attack on Titan (進撃の巨人 Shingeki no Kyojin?) is a manga series written and illustrated by Hajime Isayama. It was first published in 2009, and is serialized in Bessatsu Shounen Magazine and is currently in its seventeenth volume. 
The original Japanese title "Shingeki no Kyojin" has a dual meaning. The literal meaning is "Advancing Titan(s)" (or more literally "Advancing Giant(s)"). However in Japanese, it can also be taken as "Advance Toward the Titan(s)" which is what the localized title resembles: "Attack on Titan".
The series follows the story of Eren Yeager, his adopted sister Mikasa Ackerman, and their friend Armin Arlert. After the outermost Wall is breached by Titans, including the 60-meter tall skinless Colossal Titan and the abnormally intelligent Armored Titan and his mother dying in the resulting destruction, Eren vows revenge against the Titans and later enlists in the military, accompanied by both Mikasa and Armin. Years later during his first battle against the Titans, Eren discovers that he has the ability to transform into a Titan at will. Seen as a threat to mankind by some and as a ray of hope by others, Eren joins his companions in a desperate fight to protect what remains of their society while looking for answers to the mysteries surrounding the Titans, the Walls and his own existence as well.
