Kantai Collection often called KanColle is a popular card game from DMM and Kadokawa Games where military vehicles are moe-ified into female characters. If this sounds like Moe Moe Taisen from SystemSoft Alpha, you’re right, but the KanColle series only has Japanese ships.
KanColle has blown up into a mixed media series with manga, anime, and a PlayStation Vita game. KanColle Kai was originally slated for release this year. It was bumped back to 2015, now spring 2015 to come out alongside other KanColle projects like the anime which airs in January.
KanColle Kai is being made by Kadokawa Game Studio, the same team that developed Natural Doctrine.
