Attack on Titan Vol 4 by Hajime Isayama

Attack on Titan, Vol. 4, the Survey Corps launch a daring plan: have Eren, in his Titan form, attempt to repair the breach at Wall Rose, marking the first time in a century that humans try to reclaim territory lost to the Titans. But controlling a Titan is far from easy. Eren’s erratic power threatens disaster, even as the people depending on him’s survival rest on a knife’s edge.

As the fight rages, we flash back to Eren, Mikasa, and Armin’s grueling training period—where bonds are forged, weaknesses exposed, and new allies emerge (including Sasha Braus, the “Potato Girl”). This volume not only pushes the action further, but also deepens the world: politics, social divisions, and the cost of survival weigh heavy on every decision.
