Ao no 6-gou

In the not-too-distant future, a catastrophic event has ravaged the Earth, causing the oceans to rise and engulf most of the world's coastal regions. The malevolent scientist Zorndyke is responsible for this devastation, which has resulted in the loss of countless lives and the destruction of many of humanity's remaining cities. Zorndyke's army of hybrid creatures, beings with animalistic features, has attacked and destroyed the remaining human settlements, forcing the survivors to engage in a desperate struggle for survival. The last remnants of humanity's hope for a resolution to this conflict lie with their submarine forces, among which is the Blue Submarine #6, the focus of our story. Zorndyke's ultimate goal is to ensure the survival of his hybrid offspring by artificially inducing a polar switch using geothermal energy at the South Pole, which would decisively tip the balance in their favor. The submarine's crew, humanity's best chance for a resolution to this conflict, must now navigate the treacherous waters and confront Zorndyke's forces in a desperate bid to preserve their kind.
