Overview
After graduating from Junior High, Eren loses his will to live and becomes a shell of his former self. Armin and Mikasa try to find him a new purpose in life, when Krista tells them that the students of Marley Academy are in danger.

Summary
At the Attack Junior High School graduation ceremony, Eren cries and yells at Reiner, Annie and Bertolt, claiming he'll never forgive them for going to a different high school when they promised they'd all stay together.

The next school year, Eren, Armin and Mikasa start school at Attack High School, and day by day, Eren becomes more depressed and soulless due to his life's goal of driving out the Titans being abandoned. Mikasa and Armin decide to set out and find a new purpose in life for Eren.

They first decide to see if Eren enjoys eating new foods at new restaurants, but when he is offered his favorite food, cheeseburger, he doesn't want it and continues to whine. They encounter Sasha at the restaurant, and Eren gives her his cheeseburger.

Next, they take Eren to a pet store thinking that an animal would help Eren out. Eren seems receptive to a cat, but goes back to wallowing in his despair. As they leave, they see Connie at the register, who tells them to pay their bill.

As they walk away from the store, a soccer ball rolls over to them, and is retrieved by Jean, who brags about being a star player on the Attack FC. Eren slowly gets up and kicks Jean away.

As they return to the school, Armin says that they should have gone to Marley Academy with Reiner and co. But, his thought is interrupted by Krista, who tells them that the Marley Academy students are in danger, and shows them a picture of a Titan hand looming over them. Eren gets up once again.
