The Attack on Titan Girl Power Bundle contains: Attack On Titan Lost Girls Novel and Attack On Titan The Harsh Mistress Of The City Novels 1 & 2.
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.
Attack on Titan: The Harsh Mistress of the City was written by Ryo Kawakami and illustrated by Range Murata.
With Wall Maria breached, communities within the Quinta district have been cut off from each other creating famine and chaos. A young field commander named Rita is tasked with a mission to reconnect transit across the massive district while putting her troops and residence right in the vanguard as Titans descend on her town.
