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.
