DIO's blessing upon this wonderful world [Male DIO reader X Konosuba]

YOU BEST BELIEVE IM DOING THIS

 AS IT SAYS IN THE TITLE: YOU BEST BELIEVE IM DOING THIS! THIS BOOK GONNA BE UPDATED NEXT WEEK (hopefully)

Edit: Also wanted to include a disclaimer here, I am not following konosuba all that much in this book. The Demon King in this is probably going to be more of my own demon king rather than Konosuba's as an example of one thing thats changing. There's gonna be more of course but just a quick warning/heads up.
