Watch Gilgamesh (Sub) - Episode 1

After an explosion at an archaeological excavation research facility in the Middle East, the world is changed in unthinkable ways. The sky is suddenly a mirror, electronic devices mysteriously no longer work properly, and children who are born after this point seem to have strange, metaphysical powers. Society is but a shell of its former self, and in the midst of the clandestine forces that brought about this eerie apocalypse is an elite group of young, powerful mutants who are working to restore the world under the direction of a woman known only as The Countess.

The story centers on a brother and sister, Tatsuya and Kiyoko, the children of a scientist at the Twin X facility.
