This is a complex and diverse planet. This is a blue planet whose surface is covered by 88% of sea water. This planet is called the Azure Star.
Here, there are enemies in the deep sea that are invincible to humans alone. The Sirens in the north serve as observers and use the North Pole as an observation base. Deep-sea fleets and deep-sea amphibious ships are spread across the entire ocean. Humanity has lost 90% of its control over the sea areas.
The only hope for mankind is those ship girls born through special construction methods. Only they can regain control of the sea for mankind.
PS: This is a ship girl fanfic about main ship B, sub-ship R, and ship C, so the settings about ship girls and the deep sea are based on the settings in this book.
This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
