    I created the cover( Yes I know my drawing sucks its why i made it a story and not a comic) So as I said before this is actually a re-edited story and I decided to go ahead and change the description as well this is no longer an X reader story this is a pure fanfiction Our main character who once went by Alex is now turned into Kris from Deltarune, now he has to deal with the possibilities and dangers of the game is so fond of in real life. but now the dangers lurk even further then before because of his unusual presence, I wonder what will happen ( any and all pictures that I have created will be credited inside the chapters itself, any other pictures will be credited to their creators. Please do not reuse my arts/Drawings you are welcome to do a fan arts but not using my pictures) Inspired by @KarmaAkabane425

    Have you ever thought about what it would be like to be.. Sans? Be Papyrus' lazy and playful brother? Be a comedian with endless jokes? Be the mysterious judge? Be well-liked? You envy him. You wanted to be him. Yet nothing could've prepared you for what's coming. . . . (WARNING, THIS IS A MIX OF CANON AND FANON FACTS. THERE MIGHT BE THINGS YOU DONT LIKE BUT JUST BE THE BIGGER PERSON AND TOLERATE IT. THIS IS NOT MEANT TO BE TAKEN TOO SERIOUSLY AND IS INTENDED ONLY FOR ENTERTAINMENT.) (Cover made by me. As you can see, I made that thing on IbisPaint. I understood nothing about making book covers and I messed up on the proportion many times so I gave up and that's how the cover came to be. Idk how to shade and make backgrounds/landscapes btw) (Tbh I wished I made this far earlier because it's late 2025, no one is going to read this pile of nonsense. 😭) YOU GUYS HAVE AN OPTION TO CHOOSE THE DIRECTION OF THIS STORY THROUGH FREQUENT POLLS I MADE!!! First thought of and made on 1st Dec 2025 Posted on 6nd Dec 2025 cuz I was feeling confident for that hour. I can proudly say I've been doing this book since last year hahhahahahahahaha (get it cuz I did this thing is Dec 2025 and now is Jan 2026?)
