Attack on Titan: Part 2

After returning to human form, adolescent combatant Eren is seized by the military and sentenced to death for his titan tendencies. But before he can be executed, Eren is snatched by another titan, only to learn the truth behind their origins, the walls surrounding their colony and the government's ulterior motives. Meanwhile, Armin and Mikasa galvanise their squad and return home, looking to use a long-dormant bomb to plug the gaping hole in the wall and keep the monstrous titans at bay. (scmp.com)
