Fleet Girls are anthropomorphized representations of naval warships, primarily from World War II. They are featured in various media, including video games, anime, and manga. Each girl embodies the characteristics and historical significance of the ship she represents, often showcasing unique abilities and traits related to naval warfare. In the popular game Kantai Collection, players collect and command these girls in strategic battles against enemy fleets. The concept has gained a significant following, leading to adaptations in other forms of entertainment, such as Azur Lane, which also features similar characters and gameplay mechanics centered around naval combat.
