The Impregnable Demon King’s Castle and the Expelled Black Mage of the Hero’s Party (Official)

“Don't just stand there doing nothing you pain in the ass…! Or does your "Black Magic" specialize in that too?”

In the present era, adventurers, demons, heroes, and demon lord, are no longer occupations that put one's lives at stake. With the world at peace, it is an era where conquering dungeons has been transformed into entertainment. Adventurers and monsters are able to fight with a substitute body made of magic, popularizing dungeon conquests with no deaths. Having lost his job, the “Black Mage” Remme struggled with finding another party until one day a beautiful woman appeared before him telling she had a job for him.
