This article is about a special chapter of the manga. For the character, see Levi Ackerman.
A brief summary about the history of the Titans is given, retelling that the Titans appeared around 100 years ago and of the attack on the Shiganshina District by the Colossus Titan. Five years later as the Survey Corps prepare to leave for another expedition, Captain Levi Ackerman is introduced as mankind's greatest soldier with Hange Zoë riding beside him. As the expedition goes on, Levi tries to save a wounded soldier by killing the Titan who is trying to eat him. He then orders his squad to take care of one Titan while he takes care of two of them. After he speaks with the dying soldier as Petra Ral tries to save him. Once the soldier passes on, the Commander, Erwin Smith, tells them that they are going back to Trost District because he speculates that it has been attacked.
The beginning history of the Titans is explained and gives a brief synopsis of the events so far. One hundred years ago, Titans appeared and threatened to wipe out all of mankind. Somehow, the humans were able to build a giant three layer, walled city and managed to live in peace for the next hundred years. However, five years ago, the appearance of the Colossus Titan changed life as humanity knew it. With Wall Maria, the outermost Wall, destroyed twenty percent of the population was wiped out, causing the remainder to retreat to the safety of the second wall, Wall Rose. It was at this time that Eren Yeager, after witnessing the death of his mother Carla at the hands of the Smiling Titan, vowed to kill all the Titans.
Five years later, Captain Levi is introduced, humanity's strongest soldier, said to have the equivalent combat force of an entire brigade. As he and the others in the Survey Corps parade through the street on their way to the gates, Eren, Mikasa and Armin stare at him in amazement. Fourth squad leader Hange Zoë jokes that his admirers would be heartbroken if they knew what a clean freak he was.
Each time the Survey Corps go out, they typically lose thirty percent of their forces, which is what made soldiers like Levi so important. While out on a mission, one of his comrades is caught by a Titan. Half engulfed in the giant's mouth, he threatens him by saying that humans will overthrow them, particularly Captain Levi. As he says this, Levi appears and attacks the Titan, killing it. With reinforcements arriving, he orders Petra Ral to take care of the wounded soldiers. He then orders the other reinforcements to take the Titan on the right flank, while he takes the one on the left. Levi easily takes out the first Titan and then move on to the second, blinding him by throwing both his blades in his eyes then killing him. He then thinks to himself that they are all the same; with the same ridiculous faces. He gets blood on his hands when he finishes off one of the Titans, causing him to take pause and immediately cleans it off. Levi joins Petra and the soldier he saved earlier. Petra states that she is unable to stop the bleeding. With the soldiers dying breath, he asks Levi if he has been useful. Encouraging him, he takes the soldiers hand and tells him he has done more than enough and vows to eradicate the Titans, which allows the soldier to peacefully pass away. Commander Erwin Smith approaches them on a horse, informing them that they must retreat. Levi states that he has yet to reach his limit and asks if Erwin intend to let his subordinates die in vain. Erwin informs him of the latest attack on the city and the movement of the Titans toward it. Worried that the wall may already be broken, they leave and head for Trost District.
