Ship Girl but the Burning Boundless Sea

In a world where ship girls exist, some different stories happen... Humanity has long since perished in this world, and only the ship girls are left using the machines left behind by humans to engage in a cruel war with the Black Sea. When the beautiful girls burned their lives one by one in the flames of war and became wrecks buried under the sea, the conflicts in this world are still far away from ending... (The image of the ship girl in this book is based on the characters in the game "Battleship Girls R" and its sister ships. The missing parts may be filled in with the images in the game "Kantai Collection" or the game "Azur Lane". The combat style is based on the game "Atlantic Fleet". Larger-scale battles and strategic deployments will refer more to land warfare. The world view is set by myself. Overall, this is a college student's first attempt at writing.)
