Trigger warnings provided at the beginning of chapters. (Tags as of now are pre-emptive based on my favourite ships and characters to write for)

    "What the f*** did you do to me?!" Reaper sighs as he gets up and opens a portal. Killer glances into it and freezes as he sees a coffin being put into the ground, Nightmare, Cross, Horror, Dust and Error standing next to the hole that it's being put in, all dressed in black clothes. Horror Is crying, Nightmare looks like he hasn't slept in days and the rest of them look miserable. "You died. The fall killed you."

    Reaper was on a mission, and a fairly important one, too. He was to go undercover as a mortal, find the anomaly known as Geno CQ, and kill him. Easy, right? ...It was definitely not as easy as he thought. Safe to say, he gets a bit... distracted from his initial goal. tldr: amateur dumbass reaper x constantly on the verge of death = surprisingly good romance Ships: Afterdeath, Errorink (background), Bad Sans Poly (background), Dreamberry (background). Only the Bad Sans Poly is established at first, everything else develops over time!!! Warnings: Gay Swearing Death (duh) Injury and blood Bullying Future Lemon (will change rating to mature when I post that part, I am the same age as Geno and Reaper here so I'm pretty sure it's ok for me to write it) Poly Cover art from thedanniewannabe on Tumblr :>> Writing by me (obviously)

    None of this is in no way canon and is just a little story I thought of randomly. Please keep that in mind when reading this. Horror has a very... unexpected... secret. Out of options he has no choice to tell his boyfriends, also known as the 'bad sanses'.

    Deceived by his multiverse, Balance landed with the help of a friend in a new world, a new multiverse. He has to go through big changes in order to adapt there. He still has so much to learn. About himself and this world. Or: A what-if-scenario of my mutation-verse, if their reaction to Balance had been different.

    Please for goodness heavens, don't comment if you're really young, I had to delete enough of cringy comments. Also please don't leave any suggestive comments, there's a reason why this book doesn't have lemons (aka I'm sex repulsed). Just some one-shots about Error!Sans. Mostly fluff and some angst. Basically me throwing here whatever comes to my mind. Error is short, not because I said so, but because it's canon. In some chapters ships are directly shown, while in others they're not. If that's the case then they're probably friends, but there's nothing stopping you from seeing them as a ship. (Cover belongs to yufy01 on tumblr)

    Don't let the cover deceive you, I tend to do more serious roleplays...... occasionally based on more crack-y premises. Okay, maayyybe on the rare occasion I'll suggest a plot where Nightmare gets stuck in a mattress for 30 years until Ink buys it from a thrift store, cuts it open for a craft project, and finds him chillin in there
