Captain Levi tells the story of how the human race came to be at the end of its tether with the Colossus, Titan, and Sphinx. The humans managed to construct a wall around the city, but it was destroyed by the Sphinx, and the city was stolen from them. Five years later, the survey corps, led by Captain Levi, attempts to free the city from the wall. He tells the audience that his troops are stronger than an entire brigade of soldiers, and that they will be able to capture the city in the coming battle.
