Attack on Titan

Attack on Titan (Shingeki no Kyojin) is an ongoing manga series written and illustrated by Hajime Isayama. An anime television series adaptation produced by Wit Studio aired on MBS between April 6, 2013 and September 28, 2013, and is expected to get a second season.

Plot
The story of Attack on Titan centers around the adventures of Eren Jaeger and his best friends Mikasa Ackerman and Armin Arlert. After the wall which protects Eren's hometown is breached by Titans (giant humanoid creatures), including the 60-meter skinless Colossus Titan and the abnormally intelligent Armored Titan, a young Eren suffers the death of his mother at the hands of the Smiling Titan. Once Eren and his friends are evacuated from the district to safety, he vows revenge against all Titans and later enlists in the military, accompanied by Mikasa and Armin.
