The assumption that the future would remain unchanged was shattered by the sudden attack of the Titans. The outer wall of Wall Maria was breached, and even in the Quinta District, where Mathias and his allies resided, Titans emerged. This led to a disruption in the supply line from the nation, causing citizens to become anxious. Rita, a soldier who had joined the occupation force, attempted to safeguard the town that had descended into turmoil. However, due to the brutal tactics employed by the brigade using actual Titans, the entire city was gripped with fear. In order to locate Rita, Mathias enlisted the aid of a group of thieves.
