[The corpses of all the gods are floating at the end of the world, and there is a huge eye in the sky. ]
For the sake of the world and our future, Satana and her companions set out on the road to save this miserable world. But does the hardship along the way become unworthy the moment you learn the truth? …
In this magical world, there are three races: humans, demons, and Oga. Both humans and demons live in this continent called Sperandia.
Oga mostly lives on a sky island called Ogatia. Ogatia is the name of the island in the sky and the name of this country.
Every 100 years in this world is a century. Different gods ruled each century. The current century is called the Century of Tide and Silence.
There is only one god in every century. Before the end of the century they manage, the gods will select the next god in this world. Each god's selection method is different, either letting them kill each other, or asking them to find something... The gods of the current century of silence are missing.
