Ok this is my first fanfic, but anyways. It's been a couple weeks sense the war between humans and monster ended. The humans were of course to weak to defend they're land. And that's were you come in, you were always alone, your family was killed. But not by a monster. But instead from your own kind.

5 years. 5 years it's been. 5 years since Frisk freed the monsters. 5 years since your mom left you. 5 years you've put up with your father. 5 years of suffering and anguish 5 years of torture and abuse, mentally and physically. But that was gonna be stopped. ~~~~~~~~~~~~~ Meet (Y/N), a abused runaway with an attitude that's bound to make some people pissed. Well, that's kind of an understatement. After her mom leaving and being beat by her dad, she decides to run away, and finds a completely different world. One that makes her struggle to survive. How could she possibly make it? ~~~~~~~~~~~~ Meet sans, the laid back, lazy, and funny skeleton monster from the underground. At least, that's what he used to be. Now, he's known as Gaster Sans. He's still funny, but in a different way. All the laziness is gone. He's charming, clever, and quick. Ever since he combined souls with Gaster, his personality and appearance completely change. Will he ever feel the same, normal, again?

The monsters have finally made it to the surface and have been legalized to roam the surface as they please. The first couple of months have been spent as a paradise where humans and monsters have lived in peace and happiness. But as we all know, humans tend to be afraid of what they don't understand and the appearance of the monsters only seemed to have fueled the rising tension. You are a member of one of the biggest clubs that support the monster's appearance, known as the FMC (For Monsters Corporation). There is a rival club, known as the DM (Destroy the Monsters) that only wants to exterminate the existence of the monsters, and with every passing day, conditions only seem to be getting worse. Determined, you try to make things right and equal for all beings, but things start to alter when you meet with a certain skeleton. And with this certain skeleton, you, dear reader, reveal your biggest, most valuable secret...your little "defect". •°•°•°•°•°•°•°•°•°•°•°•°•°•°•°• COVER ART IS NOT MINE, I ONLY EDITED IT OUT FOR MY COVER. UNDERTALE DOES NOT BELONG TO ME, IT BELONGS TO TOBY FOX. I am simply writing this for the sake of my imagination, as well as for the entertainment of others. Thank you.

This is my first story. Its a Sans x Reader...basically its gonna take place after the true ending. You aren't Frisk or anything, just you. Humanity is actually happy to have monsters back. So yeah. Enjoy.

You're having flashbacks about the past and the life you had with real life monsters. You're feelings to one particular monster takes you to your limits, and you discover something extraordinary yet life changing. (sorry this sounds way better after one of my follows said it's really confusing so I'm sorry if it was) ... Weird but you will understand. ^_^

obsession for freedom.

You were working with Alphys in the lab in Undertale when chaos strikes! In a freak accident, concentrated determination is mixed with an unnamed concoction and blow you through a dimensional rift. When you reawake, you find yourself in what seems to be the beginning of Undertale once again. Upset but not overly surprised, you make your way back to Alphys's lab... Only to find her lab assistant is no longer you! Working with Alphys now is a tall, punkish skeleton with two cracks in his skull and a snarky attitude. As they help you find your way home, will you find more than that? *I DO NOT OWN UNDERTALE OR GASTERTALE!!! I WISH I DID BUT I DO NOT! THIS IS JUST A FANFICTION!!*

War amongst the humans and monsters has really messed things up for you. That is, until you meet a sexy skeleton. ((Note: this is a slow burn. You actually have the chance to fall in love instead of usual fanfic logic. Also reader is gender neutral))

Yes, the whole thing is made with arts. not words. I'm lazy to type. Btw this is Undertale and the aus of undertale + my oc and people's oc. If you do not know Undertale: It is a game developed by Tobyfox and his crew, cost about $10. Do support him by buying it. With cracks, you might have a hard time to find Gaster and the secret bosses. Sooo: Here's the story thing. You meet Gaster about 3 years later after the barrier broke, running from your deadly step-father. But you're still happy go lucky. Gaster in this point, had returned from the void he was trapped in. Introduced to the skele-family and other monsters (WITH SOME OCS LATER), funny things happened a lot. Basically, comedy romance. This is book 1: Artificial love of a Skeleton. In this book your romantic relationship will be with Gaster of course. (Gaster, in this story, is a relative to G!sans and G!Papyrus. NOT FATHER) Btw, this is a slooowwwww-burnnnnnn (takes time for y/n and Gaster to fall-in-love) Yes, you , y/n, will have complicated shit. Love is complicated, but it is easy if you trust one another and forgive one another. (Yes, another character falls in love with y/n. But since y/n's cruel, y/n friendzones everyone HAHAHAHAHAHAHA okay okay no. I mean, yeah. I give people false hopes. HAHAHAHAAHHAHAAHA Not to mention there's deaths and stuff.) Burnnn- I mean no. Anyways: There will be sad parts though, but you'll meet one OC that'll mess up the story plot and the scene. I think there's 2. Maybe 3 Idk, just count them if you want. If any of you got The Right answer i will do special chapter. (Collab with another author. Or take a request.) Let's put credits btw. Undertale belongs rightfully to Tobyfox and his crew. This spin off story belongs to me and my team. (My Sister and my friends, 2 of them. Which I'm gonna say who they are at the end of the book.) If you want to translate, go on. Post it on tumblr or idk hahahaha. But, do ask me if you want to.
