Levi's biggest challenge? - Ayumi Chagara, a tough soldier in a special unit.

But is a soldier of the Scout Regiment and former resident of the underworld allowed to have such dreams? And how can they come true when they just have lost Wall Maria and Operation Recapture is imminent?

Story "Chagara - Chaos in the Darkness":
Shortly after midnight on his birthday, Levi is standing in Peter's room with Commander Erwin, completely soaked. Peter does not belong to the Military Police Regiment nor to the Garrison Regiment and yet he is a Commander. Of what? And why does Peter resemble Erwin? But while Levi thinks about these questions, Erwin and Peter hurriedly plan their next steps. Peter's troop is about to be disbanded - a great loss for humanity, as Levi can tell from Erwin's reaction. The only solution: to join the Scout Regiment. More specifically: 50 soldiers, including Ayumi Chagara, who causes Levi to ask even more questions. Why did she choose the soldier's life? Where do all her scars come from? Why is she so familiar with Erwin and Mike? Why does he let her drink from his teacup? And why does he suddenly pick daisies with trembling hands? ... And ... who is the boy who meets Levi in front of the tea shop?
