The Girls' Journey Among the Stars

(This world is a crossover of Kantai Collection, Azur Lane, and Arknights.) The Abyssals quietly appear across the oceans. A group of girls and their admiral fight the expanding threat at sea, all unbeknownst to the world... The girls will defeat the Abyssals' rampage, root out humanity's deep-seated corruption, and march toward the stars, proclaiming with their lances of light and tungsten-alloy kinetic warheads: "On the attack, we are unstoppable! On defense, our iron fortress will never fall!"
