The Visitor and the Contractor

There exists another world separate from the present era [Far East]. Its name is [Purgatory]――a world that produces being from nothingness, from all life and death and all things. [Purgatory] contains poison, and those who harbor it within their bodies are able to wield poison as a form of magic. And beings capable of defeating the calamities and defilements that lurk in darkness. [Marebito], who are Purgatory itself, and [Contractors] And those who obtained poison for some reason――they fight. This is the story of such people. Since this is my first creative novel in a while, I'm sure there are shortcomings, but I would be happy if you could enjoy it.
