Attack on Titan: Lost Girls, written by Hiroshi Seko, 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 Mikasa and Annie. What they thought, and felt, and did on and off stage come to the fore front via a medium distinctly suited at conveying integrity: language.

The two novella-length offerings were originally included as bonus features in the initial Japanese Blu-ray releases, 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.
