Attack on Titan won't not show its face on TV again until next year, but the franchise isn't letting its anime roots rot. An update from Kodansha Comics recently went live, and it confirmed a fan-favorite spin-off of Attack on Titan is getting an anime run.
Over on Twitter, adverts about Attack on Titan began making rounds, and the promo confirmed Wit Studio is making a 3-part OVA miniseries for Attack on Titan: Lost Girls. There are few details out about the DVD extra, but Wit Studios is expected to release more details as the release draws closer. The OVAs will come included with an upcoming Attack on Titan manga bundle which collects volumes 24-26.
If you are not familiar with Attack on Titan: Lost Girls, then you have a bit to catch up on. The story was published back in August 2015 before Kodansha confirmed it has licensed the serial for a collected release. The manga is based on a novel of the same name, and Ryosuke Fuji wrote and illustrated the serial. The story itself focuses Mikasa and Annie by exploring the leads' backstories.
Attack on Titan: Lost Girls is made up for three collected stories. The first is titled "Wall Sheena, Goodbye" and follows Annie a day before the Survey Corps go on a mission to find a lost girl named Carly. Annie gets separated during the search mission and uncovers a wide-ranging criminal ring within the Stohess District which could affect her secret mission to find the Coordinate for Paradis.
The second story focuses on Mikasa and is titled "Lost in the Cruel World." The story takes place in an alternate universe where Titans never existed, so she grew up with her parents by her side. Mikasa ends up meeting Eren Yeager despite the change, and it follows the start of the two's friendship.
As for the third story, "Lost Girls" sees Mikasa and Annie come together in a brief encounter during their military training days. The girls talk about their training regimes, and they even broach the sensitive topic of why they each chose to join the military.
