The basic plot of Attack on Titan (or Shingeki no Kyojin as it is referred to in the original Japanese) is simple: humanity has been reduced to a small remnant that lives inside walled areas out of fear of gigantic, humanoid, man-eating creatures known as "Titans" and a diverse cast of soldiers strives to defend our species. However, when going through episode to episode, we will definitely be surprised because of many plot twists in the story. Moreover, the motifs that the author - Hajime Isayama uses to lay the foundation, develop the story as well as build the characters for the story is also an issue worth our in-depth analysis.
