Armin awakens to find himself surrounded by Conny Springer, Christa Lenz and Ymir. As Armin heads back to the rearguard, he blames himself not being strong enough to save Eren. Meanwhile, an Abnormal Titan approaches the city’s exit gate, which is crowded by refugees. Once Mikasa kills the Abnormal Titan, she threatens a greedy merchant holding cargo to let the refugees pass first. After she is thanked by a mother and daughter, Mikasa has a flashback. In the year 844, a year before the fall of Wall Maria, Mikasa was targeted by three slave traders, who murdered her parents in a struggle. After Grisha and Eren discovered the corpses while making a visit, Eren secretly tracked down the slave traders to a nearby hut and killed two of them in an attempt to save Mikasa. However, the third slave trader appeared and began strangling Eren. Encouraged by Eren, Mikasa overcame her fear and gained resolve to kill the third slave trader. After the children are found by the Military Police Regiment, Mikasa was invited to live with Eren and Grisha. Back in the present, Mikasa slays more Titans and goes to help the other squads evacuate.
