If Osamu Tezuka is the godfather of manga, Kazuo Umezu is the godfather of horror manga. He's the inspiration of many horror authors nowadays such as Junji Ito.

Human’s endless greed has brought Earth to its inevitable destruction. Now they have to pay the price: ecological horrors which reduce the world population from multi billions to a very low number.

The future is supposed to hold much promise for humanity -- but what if instead the whole world is struggling to survive? Environmental disasters, strange illnesses, and aliens are only a few of the worries humanity has in store in these tales of sci-fi adventure.

In a world where an epidemic, invasion, or unknown enemy has turned it into ruin, few humans have survived. The people with scientific prowess and knowledge are the world's only hope for this apocalyptic danger. Science fiction meets apocalyptic elements are present in this list of series.
