Attack on Titan: Lost Girls

Two heroines, two desperate missions—one hunts a missing heiress, the other battles a nightmare of fate.

When the enigmatic Titan shifter Annie Leonhart receives a covert assignment, she must vanish from the front lines without leaving a trace. To cover her disappearance, she enlists the reluctant Hitch Dreyse, who bargains for Annie’s help on a seemingly routine missing‑person case. The victim, Carly Stratmann, is the privileged daughter of a powerful mogul, and her sudden vanishing draws Annie into the seedy underbelly of Stohess District. With only 24 hours before the investigation collapses, Annie must navigate a labyrinth of street thugs, clandestine drug trade, and corporate secrets. Each clue she uncovers only deepens the mystery, revealing a tangled web of corruption that threatens to expose the very foundations of the city’s elite. Meanwhile, Mikasa Ackerman wrestles with a haunting premonition about Eren Yeager. As memories of past conversations with Armin and the looming dread of losing her comrades flood her mind, she slips into an unsettling alternate reality. In this dream‑like state, familiar events replay with subtle, terrifying variations, forcing Mikasa to confront the possibility that some tragedies are immutable. The OVA juxtaposes Annie’s gritty, investigative sprint with Mikasa’s introspective, psychological turmoil, offering a dual narrative that expands the Attack on Titan universe beyond battlefield carnage into the shadows of personal sacrifice and hidden conspiracies.

Two side stories set in the Attack on Titan universe: a noir-style mystery following Annie as she investigates a missing-person case tied to a dangerous drug ring, and a psychological what-if scenario where Mikasa relives traumatic events in a dream world. Expect moderate violence, drug-trade themes, and emotional intensity consistent with the franchise but slightly more contained than the main series.
