Attack on Titan OVA (2013) - Episode 6 - Wall Sina, Goodbye: Part One [English Subbed]

Summary :- On the day before the 57th Exterior Scouting Mission, Hitch gives Annie Leonhart the task of finding a missing person, Carly Stratmann, the daughter of a wealthy merchant in Stohess District. She visits the Stratmann family mansion to ask Carly's father, Elliot G. Stratmann, about the circumstances that may be related to her disappearance. After little success, she researches the Stratmann family records for further information and discovers a connection between Carly and a tavern in Stohess District, the Pit Lidors.

At the tavern, Annie learns from the rowdy patrons that Carly frequently visited the tavern and was friendly to everyone there, but she often got angry when the patrons took the drug coderoin despite her casual attitude when they took other drugs. The bartender directs Annie to the neighborhood where Kemper Boltz, Carly's lover, lives, saying that he may know more about her activities. But after searching Kemper's home she finds coderoin and the corpse of a man beneath Kemper's bed. Before her search can be complete, an irritated neighbor comes to the door.
