Ao no 6-gou

Humanity’s reckless treatment of the planet has finally come to a head, and now the very oceans have risen in revolt. The brilliant but unhinged scientist, Zorndyke, has unleashed a monstrous, intelligent aquatic army upon the surface world, drowning cities and decimating populations. As the last remnants of humanity cling to survival, their only hope lies with the elite submarine fleet, Blue Submarine No. 6, and its crew of skilled but often cynical operatives. Navigating a world forever changed, these submariners must confront not only Zorndyke’s terrifying bio-engineered creations, which blend animalistic ferocity with chilling intelligence, but also the moral ambiguities of their desperate war. With breathtaking 3D CG animation bringing the submerged battles and desolate landscapes to life, this acclaimed series plunges viewers into a visceral fight for humanity's future against an enemy born of its own mistakes.
