"Ship Girls" are anthropomorphized representations of naval warships, primarily from World War II, depicted as young women with characteristics and traits inspired by their respective ships. This concept originated from the popular Japanese media franchise Kantai Collection, where players collect and battle with these characters, each embodying the history and features of the actual vessels. The genre has expanded into various forms of media, including anime, manga, and video games, attracting a dedicated fanbase. Each Ship Girl typically has unique abilities and personalities that reflect the ship's specifications, such as speed, firepower, and historical significance, creating a blend of military history and fantasy.
