You fell into the Underground, but you cant remember your previous life. Now, you are surrounded by strange monsters, who have also never seen a human before. Will they let you live? [written 2017]

Rollertale is an au that I made. Original characters belong to Toby fox. In this au, everyone wears roller blades of some sort, either in-line, or regular skates. Most people just walk around, but I...... I love to skate. I've been skating since I was little, and now I just travel everywhere by roller blading there. Of course, stairs are hard to go up unless I take my roller blades off. I'm not really a fan of walking though, it's to much work for such little movement. I'm a usual at a roller rink called rolling souls. Since monsters were released, there is a restaurant in there called grillbys, run by a fire elemental, you guessed it, named grillby. Since I use one pair of roller blades for travel, I have a second pair that I use for roller blading in the rink. One day, a family of monsters, and the ambassador comes to the rink. Life just got a lot more interesting.

You have already been through a pacifist run for normal Undertale after curiosity about Mtt Ebott, but something doesn't feel right and when you get to the surface everything goes wrong so you do the only thing you can think of and have Frisk reset. You end up at the beginning of the game only to realize Frisk isn't there and the monsters aren't the same. They are chess players. You are curious about what Sans would be like here, and unexpectedly fall for him even though in undertale he was more like an older brother kind of guy. White moves first, so you have to make the first move the entire time and hope to win the game.

This is a rewrite of my other book Musical Souls, which is still up on my profile if you'd like to read it :) I'll add in a more personalized description as I get further in, but for now here's just a few little facts. This is a sans x reader! Pretty much normal Undertale Au but with a few small changes. Nothing to notable. Main character is a musician with a rough past, and lots of depression and anxiety issues. She loves to sing and share her ideas, as well as give advice; but tends to only open up when she is wearing her mask. A bit of a slow burn, but not annoyingly slow, as I tend to get bored with writing the same content over again. For a good while they will both be rather oblivious though. Animals (specifically cats and dogs) are common in all of my books especially this one. There will almost always be a cat with the main character throughout the entirety of the book. Sans will interact with normal main character as well as her alternate ego, and for the most part stays clueless in the beginning. Chapters tend to be anywhere between 950 words and 3000 words. I like to find a natural close to each chapter and sometimes it takes a while. Anyways I hope you enjoy.

[Underswap Papyrus x reader] You have a secret. You are the last of your kind, shapeshifter / Human hybrid. The very culmination of your being constantly pleads for you to be honest about who you are, but your kinds law prevents you from doing so. Will you be honest and open about your powers with your new friends, or will you continue to lie and hide in the dark? (Yes the title is a pun, if you aren't aware bonafide means honest/ trustworthy, yes the title contradicts itself it's supposed to show the struggle between logic and emotion.)

"There she is!" I hear an excited voice shout. This would be a fan of mine. And all of her friends are now running towards me. You know I love my fans, really I do, but I hate this kind of fan. The kind that reached for my mask. The kind that didn't want my identity to stay a secret. Just before a girls out stretched hand could grab the family heirloom that covered my face I turn and take off down the street. This was just my luck. (This is a Sans x Reader fanfiction where the reader is a Musician. She hides her identity with a mask. More information in the Prologue.) [Also: this has nothing to do with my other undertale book series] {Also again: Art is not mine unless it has been clearly drawn with regular pencil and paper, including the cover.}
