The government's demand for custody of Eren Yaeger and Krista Lenz turns Levi's newly formed personal squad into fugitives. The Survey Corps' recent successes have attracted attention, and someone from Levi's past is dispatched to take the two soldiers. To keep them safe, Levi and his squad must evade the forces pursuing them.
Before the demand, Eren had been working to improve his Titan form following his rescue from the Colossal and Armored Titans. Krista, meanwhile, was struggling with the loss of her friend, and Commander Erwin Smith was recovering from his injuries. Levi had selected Eren and his friends for his new squad. Now, with humanity still confined within two remaining walls, the soldiers face another danger alongside the Titans: human adversaries operating within those same defenses.
