Overview:
Evil reigns in the world, most of the human kingdoms are enslaved by the forces of darkness,
and those that remain are defending with their last strength.
People make up legends about ancient artifacts called "Onems". It is said that if you collect them all,
then you can gain complete control over the forces of darkness.
There are rumors that this is just a fairy tale to calm people down.
The witch Erina travels through the ancient abyss where all the monsters are rumored to come from.
The old witches convinced her that the "onem" legend was not just a legend. On her way,
she will have to meet a lot of monsters and just bad people...
But the witch does not yet suspect that something is wrong with her...
