After touching the power switch at a psychiatric hospital, Jessica transmigrated into another world as a wealthy young lady who was paralyzed in bed. She decided to laze around at home until she died.
After all, the world outside was crawling with people with supernatural abilities and demons. She had no powers or golden finger, just a little money.
It wasn't until a demon unleashed by her enemies backed her into a corner that a voice spoke from the depths of her soul:
"Twilight Sparkle, you should be dead!"
"Huh? Where am I?"
"Oh! A body worthy of me! Come on, child, let's dance!"
Aatrox: "Where shall we go to kill?"
Jessica: "I was thinking of finding a few girls to party with."
Aatrox: "You've got me wrong, buddy. I meant the ultimate plan to destroy the world. When all is said and done, what does killing mean to you?"
Jessica: "Finding more girls to party with!"
(Basically, it's the story of a crazy party animal and a Darkin going crazy, rotting, losing their minds, and having a blast together, while leading all the girls they meet astray along the way~)
