The Survey Corps rides out beyond the walls on a large-scale expedition, taking Eren with them. But the plan unravels from the very start. A Female Titan—one with human-level intelligence that targets soldiers with chilling precision—suddenly appears and tears through the long-range scouting formation. Who unleashed it, and to what end? Even the pursuers cannot see the enemy's true face, and Levi's elite squad is thrown into chaos. Volume 4 lets the scent of a human-faced enemy lurking inside the walls grow unmistakably strong.
