I present to you all a highly original story about a person who we shall call " Y bastard ", or just "Y" don't ask why. ( Disclaimer : the faux-author has taken the liberty to fill in plot holes that are yet to be disclosed )

So the story goes, in a fantasy world, there exists no kingdom with a ruler, but an emotionless ruthless God bastard who enslaves magical beings called "systems " and makes them act as grim reapers to guide souls after they are taken to the after-life by the most honorable truck - Kun.
