Nankoufuraku no Maou-jou e Youkoso: Debuff wa Fuyou to Yuusha Party o Oida Sareta Kuro Madoushi, Maou-gun no Saikou Kanbu ni Mukaerareru / Welcome to the Impregnable Demon King Castle: The Black Mage Who Got Kicked Out of the Hero Party Due to His Unnecessary Debuffs Gets Welcomed by the Top Brass of the Demon King's Army / / 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.
