Blue Submarine No.6 Anime [Hearts, Pilots]

Blue Submarine No. 6 (青の6号, Ao no Roku-gō, literally "Blue No.6"), officially translated in Japan as "Blue Sub 006", is a post-apocalyptic 3-volume manga series written and illustrated by Satoru Ozawa. The manga was published in 1967 by Shogakukan's Weekly Shōnen Sunday magazine.

When the OVA adaptation was announced by Gonzo, the manga was revised into 5 volumes under the new name AO6. It was published by Seika Bukansha and was serialized in Sebun Comics magazine in June 1997. The OVA series was released in 2000. The OVA had also received two video games for the PlayStation and Dreamcast.

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.
