Comparative statistical chart showing the correlation between real-life historical warship displacement tonnage and the breast size of associated equivalent fictional characters from the Japanese online game "Kantai Collection" (艦隊これくしょん). All raw data values relating to the real-life historical warships are obtained from publicly available information including the English Wikipedia and elsewhere, whilst the fictional character breast size is an arbitrary unit estimated by the chart's author based on visual comparison of the characters in question.The game "Kantai Collection" involves a series of fictional characters known as "fleet girls" (艦娘; "kanmusu"), who are moe anthropomorphisms of real-life historical warships from World War II. Within the game, there is a general trend where ships with a historically larger displacement tonnage are depicted with larger breasts, with the exception of certain classes of aircraft carriers and submarines, which act as statistical outliers that deviate from the general trendline.
