In ancient times, monstrous, humanoid beings called Titans nearly eradicated humanity, driving them behind immense walls to live in constant terror. These Titans are unique in their complete lack of hunger-driven motivation, instead devouring human flesh out of sheer pleasure. For one hundred years, humanity knew peace behind their walls, free from any Titan encounters. However, a colossal Titan now breaks through the seemingly impenetrable exterior wall, sparking a renewed battle against these flesh-eating terrors. After facing a devastating loss at the hands of the Titans, Eren Yeager commits his life to destroying them by enlisting in the Survey Corps. This elite military unit fights tirelessly against the ruthless Titans beyond the walls, and Eren, joined by his adopted sister Mikasa Ackerman and childhood friend Armin Arlert, must race against the clock to devise a strategy to defeat the Titans before the walls fall for good.
