You heard about it. When the barrier was shattered. When monsters were finally free. That was until another war broke down, causing them all to get trapped in the underground again. Rumors spread that the humans killed a child named Frisk for setting them free. "Every monster that we find out in the surface, will be sentenced to death." "Disgusting" "Finally, they're gone" "I hope they stay in the underground, where they belong" It makes you cringe, us, humans are the real monsters. But, you're gonna change all of that. [Quick Warning! This might probably be a slow burn]

[Y/N] lived with her adoptive mother Toriel for a while. How long is that? About three years. Throughout the time, the monsters in the Ruins know her as if they were her siblings. Flowey became way nicer each day around her, losing his soulless behavior. He cares about her so much he promise to protect her. All was well... Until she sneaked out of the Ruins. Going from Grillby's to the Librar(b)y, she went around having fun. Laws did apply, 16 being the age to leave past curfew, 18 being the age to finally date, and 21 to legally marry. One day, I slipped from my own mouth of the presence of a Princess... And Asgore ordered the Royal Guard to break the door to the Ruins... (Cover art made by Zayn-Inverse on DeviantArt)

Your a 18 year old girl named (Y/N), you've been living in the underground for 1 week and you've been staying with Tories. You had run away from a family who never really loved you except your brother. So you tried to do what most people would have done and tried to commit suicide. That plan had failed and that's when you met Toriel. You hear a noise while getting a glass of water, when you go to find Toriel she isn't there. Your panicking and running about the house looking for her. As you turn a corner, you make impact with a tall dark object.

Yeah my account was delrted so today I shall start making a story about Gaster sans and the reader..might lead to smut so be warned

You are an abandoned girl with so many battle scars. The scars you'd received from your dad. The scars you'd received from the society. The scars you'd received from fighting 'him'. ____________________________________ When I listened to this song, I immediately thought of the plot of the story. Therefore, this song gonna be mentioned a lot in this story. :333 Here is the link to the song: Gasoline - Halsey https://www.youtube.com/watch?v=1S5NDIc1_3U

*Do you fear me? "N-No" *Are you sure? "Yes." *You will learn to fear me Heh. Well here we are! I hope you enjoy this sin. I'm going to take my time and let you learn to love the characters slowly. So if you're the ones who like lemon in the first chapter, this is not for you. *Don't worry sweetheart. It will be worth it. (I don't take credit for any of the art)

THIS IS A SEQUEL BOOK!!! IF YOU HAVE NOT READ THE FIRST BOOK YET THEN GO FIND IT ON MY PROFILE!!! Anyway, now for the summary: After death, you hadn't expected much to happen. You fell immediately into a place like the void. You just wanted to reconcile for what you'd caused, but your heart had a wish of its own. You wished to turn back the clock and set things right. You wanted to make everyone forget your existence and make them happy again, even if it left you alone. Well, you're one of the lucky ones. You're wish came true and you reset time. But not everything went to plan.

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!!*

After the monsters are set free, they aren't too keen on befriending humanity. They won't show themselves yet. They will get revenge on the war the humans had waged years ago. Now they attack in secret, getting patrols and assassins prepared at nightfall. One of the pairs of assassins is Gaster!Sans and his brother. When they find a girl who is pretty, kind, and peaceful, maybe they will have a change of heart after all. (Gaster!Sans X Reader)
