[At the end of the world float the corpses of all the gods. A gigantic eye hangs in the sky.]
For the sake of the world and our future, Satana and her companions set out to save this wretched world. But after fighting their way through countless dangers, will any of it still seem worthwhile when they learn the truth?...
This is a magical world inhabited by three races: humans, demons, and the Orga. Humans and demons both live on the continent of Sperantia.
Most Orga live on a sky island called Orgatia. Orgatia is both the name of the sky island and the name of the nation.
A century in this world lasts 100 years. A different god rules during each century. The current one is called the Silent Tide Century.
There is exactly one god in each century. As the end of their reign approaches, the god chooses a successor in this world. Every god has a different way of choosing: some make the candidates kill one another, while others send them to find something... The god of the current Silent Tide Century has disappeared.
