The Attack on Titan novel Attack on Titan: Lost Girls will receive its own manga adaptation, debuting in the Aug. 9 issue of Kodansha's Bessatsu Shonen Magazine. Ryōsuke Fuji will author the manga.

Written by Hiroshi Seko and published in December in Japan, Lost Girls is based on mini-visual novels included with the Japanese Blu-ray release of the hit Attack on Titan Anime. The book collects three short stories focusing on Mikasa and Annie: "Lost in the Cruel World," "Wall Sina, Goodbye" and "Lost Girls."

Vertical Inc. announced last week at Anime Expo that it will publish the Lost Girls novel in North America.

According to Anime News Network, Bessatsu Shonen Magazine will also reprint Satoshi Shiki's spinoff manga Attack on Titan: Before the Fall, based on the prequel novel by Ryo Suzukaze (Vertical has already released both in North America).

Debuting in 2009, Hajime Isayama's hit manga Attack on Titan has more than 50 million copies in print.
