How would a normal otaku survive in a world where she is trapped in an experiment tube and in front of her is the hidden boss of her favorite novel Highschool DXD, will she be able to live a fulfilling life or will her fate be at the hands of her enemies. Or will she throw everyone into an illusion and make everything under her command? English isn't my best language so please do excuse the grammar and spelling mistakes. I don't own high school DXD or the other fanfics that are references for some of the characters in my novel. If you want to read advanced chapters go to: patreon.com/Nauty_Manu

Until one day Mio and Maria stubble upon what looks like a dungeon little did they know there would be a group to follow them not far back What or who will awaken once they both engage in a battle for territory.
