Attack on Titan: Lost Girls (進撃の巨人 LOST GIRLS Shingeki no Kyojin: Lost Girls?) is a novel and compilation of three stories written by Hiroshi Seko, a scriptwriter for the Attack on Titan anime. The first two stories, "Lost in the Cruel World" and "Wall Sina, Goodbye" are based on the visual novels of the same names, released on the Blu-ray copies of the anime. A third story, "Lost Girls," was a new release. The three stories were also adapted into a manga of the same name.


LOST GIRLS tells of the times and spaces in between the plot points, through the eyes and ears of the saga's toughest - but more taciturn - heroines. What they thought, and felt, and did on and off stage come to the fore via a medium distinctly suited to conveying interiority: language.

The two novella-length offerings were originally included as bonus features in the initial Japanese Blu-ray released, while the introduction and the titular story are unique to the book. A manga rendering of this official spinoff is slated to appear stateside from Kodansha Comics.[3]

Lost Girls

As Mikasa Ackerman sends Annie Leonhart's Female Titan plummeting to the ground in Stohess District, a flood of memories rush into Annie's mind. Among those memories, Annie recalls a moment when she and Mikasa spoke in the year 849, during their days in the 104th Training Corps.

While peeling potatoes in the kitchens of the training grounds, Mikasa arrives to give her the silver blade-ring Annie keeps on her person. Mikasa asks about the blade within the ring, to which Annie tells her that it is a self-defense item. Mikasa is skeptical of an expert fighter like Annie needing such an item. Annie lies to Mikasa, saying that the ring is a gift from her parents. Mikasa explains that she does not want Annie to wear her ring when sparring with Eren Yeager, to avoid injuring him.

As she is about to leave, Mikasa asks Annie why she joined the Training Corps. Annie claims she wants to join the Military Police Brigade, and Mikasa believes that Annie's desire is out of some necessity rather than coveting a luxurious life. Mikasa asks Annie what is burdening her, and Annie brings up her ring. She cannot be callous towards the trinket, she says, because of the purpose behind its design, even if it is a trivial one. After Mikasa leaves, Annie thinks to herself, hoping that the day the ring must be used will not come, despite knowing that such a day is inevitable.

In Stohess District, Annie's memories come to a close as her Female Titan falls.
