Shingeki no Kyojin: Ano Hi Kara

After the Colossal Titan breaches Wall Maria, Eren Yeager loses his home and his mother to the Titans, driving him to swear that he will eradicate every one of them. He joins the military alongside Mikasa Ackerman and Armin Arlert, only for the Titans to break through again at Trost before their training has truly prepared them.

In the battle, Eren reveals an impossible ability to transform into a Titan himself. His power helps humanity reclaim Trost, but it also makes him a source of fear and suspicion. With his fate under military judgment, the question becomes whether Eren is humanity's greatest weapon or another threat within the walls.
