Battleship Girls: the Rise of the Admiral

In World War II, all sea routes in the world were impassable due to the attack of the Black History Fleet. In order to regain control of the sea, humans created equipment based on battleships in human history. These equipment can only be used to adapt to the situation. These adaptors are all the only ones in a hundred, and the higher the adaptability, the rarer they are in this world... This novel and its characters are purely fictitious.
