Erita

The Earth has been ruined by human greed and left covered in a strange substance. The only human being left is Erita, a six-year-old child; Erita is humanity, and humanity is Erita. Gaon, an artificial intelligence with the special order to "always put Erita first" constantly sends rescue messages into space to ask for Erita's salvation from aliens, who Gaon believes are better than humanity.

But will the message reach them? Can Gaon keep Erita safe on a mutant monster-infested Earth? In the face of humanity's greatest crisis, Gaon must choose between the Erita of today and the Erita of tomorrow.
