Attack on Titan: Lost Girls

At Stohess District Military Police base, Annie tells her roommate that she needs a day off. In return she agrees to help find her roommate's friend, Carly Stratmann. Annie visits Carly's father, who appears to know very little about his daughter, but Annie suspects that he is withholding information. Stratmann owns the Marleen Company which used to trade between Wall Maria and Wall Sina, but now the company is on the brink of collapse although he appears wealthy. Annie traces Carly to the Pit Riddles bar where Carly appears to be a regular, with more money than she should have. There, Annie physically extracts information about Carly's boyfriend Kampfer Boltz from some regular customers. She investigates his accommodation, finding a large quantity of the illicit drug Codeloine and a body under the bed.

Annie confirms the body she found in the apartment is that of Kampfer Boltz, which places her in a difficult position as a Military Police officer. As she leaves, she is intercepted by two other investigators, Wald and his assistant Lou. They prepare to dispose of her, but she tricks Lou into triggering her Titan form, however when she returns to normal, Lou shoots both her and Wald. Annie recovers from the fatal shot and the wounded Wald reveals that Stratmann had also hired him to find Carly, and Stratmann knows all about her secret life. Before he dies, Wald tells Annie that Kampfer offered to hire them to blackmail Stratmann about his daughter's situation and demand a ransom for her return. Annie tracks down Lou, finds Carly and then discovers that she and her father are involved in manufacturing and distributing Codeloine. To cover her own involvement, Annie eventually arranges passage for Carly escape to Wall Maria. Annie's next task is to infiltrate the Survey Corps' 57th reconnaissance mission and capture Eren Jaeger.

At Wall Maria, Mikasa has a vision of her family life when she first met Eren, the son of Doctor Jaeger. Walking together in the woods, she and Eren encounter wolves eating human bodies, but when Eren approaches them, the wolves retreat. The two children gradually became friends and Eren tells Mikasa about his friend Armin and his dreams of joining the Survey Corps and visiting the outside world beyond the wall. Although she likes him, Eren is only fixated on his dreams, even after seeing Survey Corps casualties caused by encounters with Titans and injures he suffers fighting to defend their reputation. When Eren tells Mikasa that he and Armin plan to "jump" the wall in a hot air balloon she wants to go with them. However at the appointed time, she is intercepted by a masked "man of the mirror" who threatens to turn her into a killer and tells her that she cannot avoid Eren’s death. She appears to kill the man, but it is only a trick and she continues to the meeting place. Mikasa eventually finds Armin, who tells her that Eren sacrificed himself to save him. Back in the present, Mikasa realizes that Eren will follow his destiny and that she will be by his side.
