Royal Government arc

The Uprising arc is the sixth story arc of Shingeki no Kyojin series.

Introduction
The situation inside the walls becomes critical after the murder of Pastor Nick and a subsequent attempt to kidnap Eren and Historia. Knowing that the king's actions greatly endanger the humanity, Erwin begins his plan - the plan to overthrow the government!

Summary
The soldiers finally return after Eren's rescue, albeit in a terrible state and with a lot of casualties. Eren blames himself for allowing to be captured, however, after Jean and others speak to him about the possible ability of him controlling the Titans, he regains his resolve. Meanwhile, it is revealed that humanity would barely have enough food to support the refugees for a week if Wall Rose were to fall. Dot Pixis reveals these details to Erwin. Levi expresses pity at Erwin's lost arm, but Erwin claims it's a small price for all the soldiers that have died due to his orders. They are then joined by Connie and Hange who reveal the possibility of Titans being humans completely fused within their body. This theory is supported by the events in the Ragako Village as all the humans have seemingly turned into Titans, including Connie's parents, much to his sorrow. Levi then reveals to Erwin that his team has been remade with several members of the 104th Trainees Squad members in order to watch over Historia and Eren. Far away from any civilization, Eren is reminded of the original Levi Squad as his new team bickers among themselves.

Some time later, as an imperfect Titan form of Eren falls to the ground, Mikasa and Hange are forced to remove Eren's body from the Titan by force. A day later, after Eren wakes up, not remembering anything, he is informed of the experiments' results, learning that he has shown no signs of the hardening ability and even lost his intelligence after mysteriously recalling about his father. After Levi describes their situation to be quite bleak and Hange suggests to focus on the Wallists, Eren suddenly witnesses an image of a girl, not knowing her identity or where the memories of her come from. In the capital city, Mitras, Erwin rides a carriage along with Nile Dok, when the former questions the later about Pastor Nick's murder, much to the shock of the Military Police Brigade's Commander. It is revealed that the interior Military Police is not directly under the Brigade's command. The two then recall their past as they talk about Nile's wife, Marie, and eventually Erwin's decision to choose Titans over her. Meanwhile, Levi's Squad recieves their orders from Erwin and they eventually reach the Trost District. After Levi is confronted by several villagers, Eren and Historia end up being kidnapped. However, it is revealed that the two kidnapped are Armin and Jean in disguise. Mikasa and Levi easily track the kidnappers' location and prepare to act, the latter ready for action with his foot injury feeling better.

The kidnappers enter the warehouse where Armin and Jean are being kept and are ambushed by Mikasa and Levi who had taken out the guards before their arrival. Subduing the three kidnappers, Levi interrogates the boss who Mikasa recognizes as the merchant boss, Dimo Reebs, that was blocking the gate during the Trost incident. Insisting he doesn't know anything, Levi takes Reebs to the top of the wall blocked by Eren overlooking Trost. He points out that Eren blocking the broken gate is what saved the merchant's town, then he asks him what his motives were for kidnapping Eren and Historia and the negotiations between the brigade for doing it. Claiming he was following orders and that he was threatened not bribed, Reebs points out that as a result of their failure his business will be seized by the government and his workers will lose their jobs in addition to his and others' lives being silenced. Levi talks about how if the merchant's business vanishes, Trost will stop functioning and many would suffer. To this Reebs asks if he will give Eren and Historia to prevent that which Levi replies he will under three condtiions. That his company would rise up against the government and central brigade with the Scout Regiment, that the company will completely trust the Scouts, and that when ever the Reebs Company obtains rare food or luxury items that they will first give it to the Scout Regiment to which the merchant accepts all conditions. On a rainy night, Reebs takes two of the Central Brigade's officers, Sanes and another, in a wagon to where he tells them he's keeping Eren and Historia. The wagon slips of the edge of a cliff and the two officers fall into a running river and disappear. As this was Reeb's plan, the officers are taken by the Scout Regiment where Sanes is bound to a chair with Levi holding pliers, wearing a blood-stained apron, and Hange setting a tray of small torture tools.
