"In the early 21st century, the majority of Earth's landmass is submerged due to rising sea levels. Enter the Fleet of Fog, a host of sentient alien battleships of unknown origin who easily decimate earth's naval forces. Humanity is now on the verge of extinction. In the year 2039, the stalwart Captain Chihaya Gunzou and his intrepid crew on the Blue Steel fleet may be humanity's last chance to fight off the alien invaders. The Blue Steel fleet happens to contain a secret weapon that could turn the tide of war: a mysterious I-401 submarine that can transform intoa girl"--OCLC.

"The Fog battleships Haruna and Kirishima have been destroyed through the combined efforts of the I-401 and the Japanese government's "White Whale" sub, and the port of Yokosuka is safe--but the same can't be said for the I-401. While still damaged from the battle, the 401 comes face to face with a Fog submarine that Iona doesn't recognize, and it's not exactly friendly! Back on land, Haruna, the mental model of the destroyed ship, is found by Osakabe Makie. The mental model and the precocious human child strike up an unlikely friendship, and Haruna learns that there's far more to Makie than meets the eye"--Back cover.

"Chihaya Gunzou, captain of the sentient submarine known as I-401, is renowned for his unorthodox tactics. His unpredictability is a strength when it's just him and his crew against the world, but with two massive Fog battleships attacking their home port, Yokosuka, the I-401 has to team up with a human-built submarine to try to take them down--without letting the Fog ships anticipate their next move!"--Back cover.

"The I-401 and her intrepid crew, captained by Chihaya Gunzo, have escaped the trap set for them by the Fleet of Fog outside their home port of Yokosuka. Successfully returning home after two years away should be a triumphant occasion, but there are those who think otherwise. In fact, if they have their way, they will take the I-401--along with her mental model--Iona, away from Gunzo entirely and bring her back under government control"--Back cover.

"The mansion where Professor Osakabe and Makie live is under attact, and nobody is happy about it: not the government, not the residents, and not even the attacking soldiers, who find themselves face to face with Haruna and learn firsthand that even without their battleships, the Fog's mental models are a force to be reckoned with! Haruna's world has been turned upside down since the I-401 destroyed her and Kirishima's battleships, She's learned that Osakabe Makie is a Design Child, and a potentially valuable resorce for the Fog, but Makie has also become her friend. And now Haruna is quickly learning to the meaning of both "friendship" and "loss" -- concepts she's never have to grapple with before"--Back cover.
