Girly Air Force (ガーリー・エアフォース, Gārī Ea Fōsu) is a Japanese light novel series written by Kōji Natsumi and illustrated by Asagi Tōsaka. A manga adaptation by Takahiro Seguchi launched Monthly Shōnen Ace in October 2018, and an anime television series adaptation by Satelight aired from January to March 2019. Earth has come under attack by the Zai, a mysterious "armed group" using unusually highly advanced weapon systems far superior to any Terran military technology. A young Chinese-Japanese teenager named Kei Narutani and his Chinese friend Minghua, both living in Shanghai, are force-evacuated to Japan when the city is attacked by the Zai. During their escape by sea, several Zai fighters begin sinking the evacuation fleet when Kei suddenly witnesses the Zai being repelled by a strange airplane. When the plane subsequently crashes, Kei rushes to aid the pilot, but is surprised to find a pretty girl at the controls.
