Shingeki no Kyuojin (SnK), is a Japanese manga series written and illustrated by Hajime Isayama. Snk is set in a world where human live inside cities surrounded by towering walls. They were forced to retreat behind those enormous walls of a fortified city to escape the massive, man-eating Titans (-giants) that roamed the land outside their fortress. Titans seem to have no intelligence, devour human beings and, worst of all, seem to do it for the pleasure rather than as a food source.
