The story is set in the distant future, when the Earth's oceans have risen and flooded most of the sea-lying land on Earth. The rogue scientist Zorndyke caused the flooding, which killed countless individuals, and most of humanity's remaining cities have been attacked or destroyed by Zorndyke's army of half-animal "hybrids". The remaining humans begin to wage war against Zorndyke's seagoing creations for survival. Humanity's best hope for a resolution to the conflict lies with its submarine forces, among which is the focus of the story, Blue Submarine #6. It is revealed that Zorndyke is attempting to decisively end the conflict in the favor of his hybrid children by artificially inducing a polar switch using geothermal energy at the South Pole. Characters
: The lead protagonist who is a pilot for underwater vessels. He is contacted by Kino to help with the Blue Fleet operation. : A young woman around 18 years of age who enlists Hayami to help the crew of Blue 6.
: The Captain of Blue 6. While serving in the Marine Self Defense Force Submarine Division, he became an alcoholic and his wife and child left him. He became an instructor at the International Naval Academy by swearing to give up drinking. He is a veteran of Musuca battles and has experience in fighting Verg. Understanding his former student; Tetsu Hayami's great abilities and seeing the need for them, he pushed him to rejoin Blue Fleet. : The antagonist of the story, who is supposed to be attempting to destroy humanity. He has created a series of hybrid creatures to carry out various tasks, known as the Army of Chiron. Many seem to have gone beyond his control, though they claim to be doing his will. : The "Admiral" of Zorndyke's navy. He is very prone to fits of anger and jealousy and even savagely attacks Mutio for interacting with a human. His biggest motivation appears to be his "Papa"'s approval, and he constantly seeks it by killing humans. He foolishly believes that humans make his "Papa" sad, and not the war(s) they are involved in. : A member of the aquatic hybrid race created by Zorndyke (often referred to as nereids). She is saved by Hayami and she later returns the favor. She becomes an outcast due to her interactions with Hayami. Even though she was banished by Verg and brutally beaten by her sisters, she still consoles him in the last episode. This forgiving nature may have developed during her interactions with Hayami and the Musuca Red Spot, or because of her natural compassion.

However, since the announcement, there has been no news nor reports of any progress. Reception
Eric Luce of Ex criticized the second manga for its characters and pacing stating: "This manga moves so slowly, one is tempted just to skip pages at a time to find a scene where something is happening. The characters seem to exist without a past so they lack any real depth". The Blue Submarine No. 6 OVA was ranked as the 70th best anime of all time by the Japanese magazine Animage. It was ranked 25th best anime of all time by Wizard's Anime Invasion. The Society for the Promotion of Japanese Animation awarded the it "Best OVA, U.S. Release" for 2000. Anime News Network praised the OVA for its animation stating: "Oceanscapes are beautifully rendered, aircraft looks extremely realistic, and the underwater fighting is simply breathtaking". However criticized the characters stating: "The characters, although nicely designed, are sparsely drawn and shaded, and there is absolutely no personality to them whatsoever". Eric Luce also praised the graphics and animation stating: "The producers of this show are pushing many boundaries in composition and editing. this show is probably one of the best uses so far of integrating the two". Bryce Coulter of Mania criticized the plot stating: " The flashy production and great musical score doesn't mean a whole lot without a decent plot. Blue Submarine No. 6 tends to ride the fence in this area". Carlos Ross of THEM Anime Reviews initially praised the series for its graphics, plot and characters. However a decade after the review and CGI and cel shading became the norm in animation, he updated his review criticizing the characters and plot. He had since referred it as a transition between classic "acetate age" and the modern computerized form of Japanese animation. For the Blu-ray release of the OVA, Anime News Network gave a more positive review stating: "Despite some dated-looking CG, on the whole Blue Submarine No. 6 stands up surprisingly well. Its writing flaws may have become more apparent over time, but it can still be a thrilling view and its roughly 120 minute total length keeps the story so compact that viewers do not have much opportunity to get bored". Helen McCarthy in 500 Essential Anime Movies claimed that anime had "an interesting story, beautifully animated, with some jaw-droppingly good design concepts". She praised the characters design, especially Zorndyke's and stated that director Maeda "is one of the most imaginative visualists in anime". See also
