Here in the world of Giants Attack, where the reconnaissance teams fight with all their might to liberate the people of Dia and Paradise Island from the giants sent by the scientist and Marley,.... Strange events begin to take place, inside the great walls after they know the truth about the Marley, wars have broken out on all fronts. But in a mysterious month, unknown teams began to appear at night... It controls the giants from afar, stops them with a word, and disappears without a trace. People call them "shadows" . Every attempt to track them fails, no one knows where they are coming or where they are going. But the secret investigations revealed something terrifying: The DNA of the Shadows matches the lineage of Levi, Irwin, Mikasa, and even Irene. As if they were their children... But there is no evidence. Hanji says worriedly: "So that's true... We are fighting the future itself." In the midst of the battles, a mysterious shadow looms over the walls of the Marley — a girl with long black hair who moves faster than any soldier, stops only one giant, and then disappears before anyone can reach her. No one knows her name, But they call her among the armies: "the leader from another time." She is the one who leads them... She is in charge of everything. Levi whispers as he watches her from afar: "The way it moves... Look."
