Shingeki no Kyojin blends themes from shōnen and seinen meta-genres ( Bryce & Davis 2010 Shodt 1996), but also from post-apocalyptic fiction, horror, and other genres. They seek revenge by enrolling in the survey corps, a military force with the mission of reclaiming Titan-infested territories, but become involved in a complex web of conspiracies involving the survival of humankind. The story focuses on step-siblings Eren Yaeger and Mikasa Ackermann, and their friend Armin Arlert, who lose their families in a Titans attack. The outer cities and districts host peasants, workers, and merchants. The city inside wall Sina is home to the nobles and the royal family.

Each wall also marks social and economic distinctions. The last survivors of the Titans’ onslaught found safety in three cities surrounded by concentric walls: wall Maria (outermost), wall Rose and wall Sina (innermost).

Shingeki no Kyojin or ‘Attack on Titan/The Attacking Titan’ ( Isayama 2009–ongoing) is a manga that features the fight of humankind against the ‘Titans’, human-looking creatures that vary in height and size, display little or no intelligence and eat humans for no apparent reason.
