Piggy x Reader

The Reader is visited by a demon to be kept alive during a apocalypse, forcing them to be mentally tortured beyond recognition.

Piggy x Reader is a fanfiction where the reader survives in a Piggy multiverse. For the book to end, I will have to reach 12 main chapters, but I am using a wheel for naming the chapters so I wouldn't know when it ends.
On the wheel:
I choose (main chapter)
What I imagine next (main chapter; just what I immediately imagine to happen next)
Randomly picked reference (Main chapter),Where I pick a reference chapter from anything. For example if I chose Piggy for chapter one if I landed on this, then I have it be House or Alleys or something involving a first chapter like Decay. Or a book or show not about piggy or related to Piggy but I name the chapter after one of the first places in it.
'Extra chapter (spin again)"I land on it, I spin again to what the extra chapter will be about. the extra chapter is what will possibly make the book longer than 12 chapters. I want to make multiple books, unlike Piggy which only has 2 books. "Character reference" Instead of a place for a main chapter, it is a character and the place don't matter. Each book of this small fun series will have the cover be the first infected/non-infected to chase/attack the reader.

And the reader in each book is the same character and the books will have lore and plot. Just instead of the Piggy main lore. Just the reader's lore and adventures. Each book will have one main plot which is at the very top of the description.
