Attack on Titan (Manga)

Attack on Titan (進撃の巨人) 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 eighteenth volume.

Title
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".

Plot Summary
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.

Prequel
A prequel to the series titled Attack on Titan: Before the Fall has been released in Japan in the form of a light novel. There are three books so far. The first is about a weaponsmith named Angel Altonen and his development of what would become mankind's best weapon against the Titans, Three Dimensional Maneuver Gear. The second and third books chronicle the mysterious origins and life of a boy named Kuklo (meaning "one eyed giant" in greek - "Κύκλωπας") and his struggle to be accepted by the townspeople after being found as a baby in the remains of a Titan.

These novels are also being adapted as a manga.
