Declaration of War

Sensen Fukoku (宣戦布告)

Willy begins his theatrical presentation to the local and international audience while Eren and Reiner listen in a basement below the stage with Falco. Willy tells the well-known story of Marley's hero Helos, who formed an alliance with the Tybur family to defeat the Eldian King Fritz. However, he reveals Fritz and the Tybur family fabricated the myth themselves. 

King Fritz actually wanted peace and willingly went to Paradis Island with the remaining Eldians, vowing to renounce war. His ideology was passed through his bloodline, which kept his successors bound to his desire for peace while vowing to release the Wall Titans if the peace is shattered by Marley. Meanwhile, Pieck and Porco are sent down a trap door by a Marley soldier which drops them into a small, stone-walled cellar which effectively prevents them from transforming into Titans. The Panzer Unit is sent to look for them. 

Back in the basement, Eren reminds Reiner of their past as adversaries. Eren explains that since his arrival in Marley, he has realized that the two of them are alike, but with contrasting beliefs due to their different upbringings. They hear Willy announce above them that Eren is a threat to world peace as he is not of the Fritz family after gaining the abilities of the Founding Titan as Eren's parts start to regenerate. 

Just as Willy declares war on Paradis, Eren transforms into the Attack Titan and bursts out of the basement, throwing Willy into the air and positions himself to consume the figurehead of the Tybur family.
