Guilty Shadow

""Why?" Really? You don't get it? I'm the same as you. I didn't have any other choice. That's why."

- Eren reveals his intent to Reiner

Guilty Shadow (疾しき影) is the 1st chapter of the 25th volume and the 99th chapter overall of the Attack on Titan manga, written and illustrated by Hajime Isayama.

Overview
Reiner is shocked by Eren's presence in Marley, and begins breaking down after Eren indirectly threatens the civilians watching the festival above. Falco is instructed to stay in the room. Lord Tybur finishes his preparations, as crowds take their seats. The presentation begins, and an apparent Marleyan soldier summons the Warriors on behalf of Magath.

Reiner questions Eren on why he came to Marley. Then they begin to listen to Willy's speech, where he recounts the understood history of the world. Eren and Reiner continue talking, and Pieck and Porco are led into a room, where a trap door is pulled underneath them. Falco realizes Eren is from Paradis, whilst Willy declares that the known history is a lie. He explains it was King Fritz who saved the world, and never actually posed a threat. He expands though, that Karl Fritz' power has been stolen, and a rebel resisting world peace had appeared: Eren Yeager.

Summary
Years ago, Bertolt continued to discuss with Reiner and Annie about the suicide victim they came across. Annie mused that he wanted someone to forgive him for his past actions, something they do not deserve since they abandoned Marcel. Bertolt theorized that he wanted to instead be judged by someone.

Back in the present, Reiner is still stunned to see Eren. Confused by Reiner's reaction, Falco says he must merely be surprised to see Eren after such a long time; Eren thanks Falco for bringing Reiner to him, mentioning that unshared stories to tell. He then asks Reiner to sit down. When he hesitates, Eren mentions that they can hear the stage very well from where they are. He notes that the building above them, although located in the back of the stage, is full of people anxiously waiting to see the play. Eren finishes by showing both Falco and Reiner his hand, which is now bleeding; realizing the gravity of the situation at hand, Reiner finally sits down. When Falco tries to leave, both Eren and Reiner request that he stay.

Right before the play begins, Willy Tybur is informed that it is time to head to the stage. He is greeted by Kiyomi Azumabito on the way out. He comments that he must look terrible, but she instead says that he is brave and bids him farewell. After he departs, she motions to both her bodyguards and leaves the area. In the stands near the stage, Reiner's mother Karina spots Mr. Leonhart, Annie's father. He comments that it has been some time since they saw each other. They talk for a while and Mr. Leonhart mentions that Mr. Hoover finally passed away peacefully in his sleep. They reflect on how he was proud of his son devoting his life to Marley. When Karina mentions Annie as well, Mr. Leonhart disagrees, reaffirming that his daughter is not dead but still alive. While they wait, Pieck notices many higher-ups in attendance including General Calvi and numerous ambassadors and friends of the Tybur family; Colt states the power of the Tybur family is impressive, despite Porco's comment that they are still Eldians like the rest of them. As the ceremony begins, Udo and Gabi both notice that Reiner and Falco have not yet returned. Just then, a soldier approaches and informs the Marley Warriors that General Magath has summoned them. Underground, Falco realizes the play has started. Reiner asks Eren why he is in Marley. When Eren replies that he is here for the same reason as Reiner, he does not have a choice, Reiner starts to break down and tremble.

Willy Tybur comes on the stage and tells the story about the bloody history of Marley and Eldia. The Eldians ruled the world by utilizing the power of the Titans. According to their information, the number of people lost from then until now is estimated to be three times that of the current global population, including the eradication of numerous ethnicities and cultures. The Great Titan War began once the enemies of Eldia were all gone, using eight of the Titan powers to constantly fight amongst each other. Then the Marleyan hero Helos aligned with the Tybur family to force King Karl Fritz to flee the island, but he left with the powers of the Founding Titan in his possession. Willy goes on to discuss the failed Paradis Island Operation with the return of only two out of the four Titans that were sent. Eren reminds Reiner that he and his comrades were trying to save the world when they destroyed Wall Maria.

The soldier escorting Pieck, Porco, and Zeke orders the latter to go to the front door and has the other two follow him. Pieck tries to start a conversation with him but the man mentions that he was just sent in for security and has no intention of talking with her. On their way there, Pieck spots her Panzer unit, the soldiers who man the guns on her Cart Titan. She briefly greets them before the they continue to follow the soldier. Eventually the soldier escorts them inside. When Porco asks where Magath is, the soldier brandishes a knife and triggers a trapdoor, trapping both Pieck and Porco underground.

Falco is curious about Reiner's behavior towards "Mr. Kruger", asking himself if they are truly old friends. He then realizes that Eren and Reiner must have known each other from when Reiner was on Paradis. Up above, Willy declares the truth for the first time: it was not Helos nor the Tyburs who were the heroes of Marley, but King Fritz. A pacifist, he took pity on Marley and aligned with the Tybur family, fabricating the deeds of the hero Helos. He reveals that they were behind the collapse of the Eldian Empire and mentions that the King's threat of unleashing the Wall Titans if their peace was disturbed was also a lie. His belief of peace would be carried down with his successors, as well as freedom for Marley: the Founding Titans would be held to Karl Fritz's vow renouncing war, and if the day would come when Marley arrives to destroy Eldia, they would accept it. However, King Fritz's final wish was for a brief era of peace for him and his people.

As the crowd begins to wonder about this revelation, Willy proclaims that the desire for peace was destroyed by the recent rebellion that has taken place on Paradis. Proclaiming that someone of non-royal blood has taken the powers of the Founding Titan, he states the world is now facing yet another crisis. A rebel against peace is coming for Marley, and his name is Eren Yeager.
