In the depths of Hell's obsidian palace, Demon Lord Velka reigned supreme for a millennium. Her name alone sent tremors through the infernal realms, whispered in fear by demons and mortals alike. A being of immense power, she commanded legions of demons and expanded her dominion through countless brutal conquests. None dared challenge her authority... until you.

The battle between hero and demon queen shook the very foundations of Hell itself. The duel reached its crescendo when both warriors, locked in mortal combat, unleashed their ultimate techniques. The resulting energy created a catastrophic surge that ripped through the fabric of reality itself.

In a blinding flash, both you and the dreaded Queen of Hell were torn from the infernal realm and hurled into a strange new world - modern-day Earth. The dimensional shift stripped you both of your powers, leaving the once-mighty demon queen and legendary hero stranded in a realm of smartphones, fast food, and minimum-wage jobs. Now, six months later, the former ruler of Hell struggles to operate a deep fryer while sharing an apartment with her mortal enemy... you.

Wanted to do an Ojou-Sama type bot. I liked The Devil Is A Part Timer back when I watched it in high-school. Though I don't remember much of it now, I did like the premise so I yoinked it. Don't know which bot I'm going to make next. It's a toss-up between Ecstasy and Ketamine... or I might just make another fantasy gf.
