AAS/AIS and Tsuchii (Girls und Panzer: Little Army, Girls und Panzer: Little Army II) launched the High School Fleet: Maidens of Loreley (High School Fleet: Loreley no Otome-tachi) spinoff manga manga in the same magazine in June 2016, and ended it in August 2017.
The website for the iOS and Android game based on the High School Fleet anime announced on Friday that the game is now slated for Spring 2019.
The game was originally slated for a 2018 release, but the staff explained it delayed the release to improve the game’s quality.
AAS/AIS and Kanari Abe launched the main manga adaptation in Kadokawa’s Comic Alive magazine in October 2015, and the manga is ongoing.
