This is a complex and diverse planet, a blue world whose surface is covered by 88 percent ocean, known as Azure Star.
In its deep seas dwell enemies that humanity cannot defeat alone. The Sirens in the north observe the world from the Arctic, while the Deep Sea Fleet and Deep Sea ships are spread across the oceans. Humanity has lost control of 90 percent of its seas.
Humanity's only hope lies in the ship girls, born through special construction methods. Only they can help humanity reclaim control of the seas.
PS: This is a ship-girl fanfic focused on Ship B, with Ship R and Ship C as secondary pairings. The ship-girl and Deep Sea settings are based on this novel's own interpretation.
This novel and its characters are entirely fictional. Any resemblance to actual people or events is purely coincidental. Please do not imitate.
