This is a story about an advanced submarine shipgirl who yearns for the sea, along with her captain and crew.
"Coastal Defense Front S" shares a setting with my previous work, "Coastal Defense Front D," but stands alone as a completely different story in the same world. It can be read independently and won't cause any confusion.
1: This work has an original setting and world, and features shipgirls.
2: This is not a derivative work of any shipgirl or shipgirl-like series, and the shipgirl designs do not use character settings from those works.
3: The story can be considered an alternate world.
4: If you'd like to try something different in a shipgirl story, give this one a look.
