Gilgamesh

is a manga series written and illustrated by Shotaro Ishinomori. It was serialized in the Shōnen Gahōsha magazine Weekly Shōnen King from 1976 to 1978.

Plot
The story begins as the Tomb of Gilgamesh is discovered by a young scientist named Terumichi Madoka, causing the world's most recognized scientists to gather, initializing the Heaven's Gate project. When an unknown life form called Tear materializes in Delphys - a pit that seems to have no dimensions and that surrounds the tomb of Gilgamesh - and begins to contaminate embryos that surround it, the scientists decide to stop the project completely. However, Dr. Madoka breaches the guard around Delphys and comes into direct contact with Tear, causing an immense explosion that blocks out the sky with a mirror-like layer. This is considered an act of terrorism, as after the explosion, computers and wireless communications stop working, and the planet falls into war and famine.
