{THERE IS LEMON BUT READING IT IS OPTIONAL AND WONT AFFECT THE STORY} You've aspired to be a Monster specialist ever since the monsters had left the Underground. You leave on your first expedition to find as much information on each Monster as you could but then you're sidetracked when you wander into a cave, where the barrier once stood, though you didn't know it and helplessly wander into the Underground and meet a strange skeleton who really sparks your interest.

NOT A LEMON. just wanted you to know that. I love Sans. He's the best. So, what better way to show it, than a fanfic where we date him? Y/n is a half human. Her mother was human, and her father, a skeleton. The moster war was 50 years ago, but ever since Frisk disapeared 30 years ago, human hostility towards monsters has increased. An entire mob of humans killed and entire monster villiage, and y/n's mom, that lived at the base of Mt. Ebott. That was where Frisk was last seen, and so humans assumed they killed her. Y/n, now 22, survived however, by running up Mt Ebott, and falling. What will happen now? Read to find out.

Despite her doubt in him, Ink treats (Y/N) like his younger sister and she loves him like the family she never had. They live in a house together in the Doodlesphere where Ink protects her with his life, determined to keep her safe. She is friends with just about everyone from all AUs and travels with Ink whenever he goes to one. There's only one place Ink doesn't take her. The anti-void. Why? She has no clue.

(Y/N) is finally ready to go back to the monsters she holds so dearly. After about a year of mental and physical training she has finally gotten her emotions under control. But has she gone emotionless? After plugging the thumb drive with her save file on it into her computer, (Y/N) soon discovers something. In a desperate attempt to save themselves, or maybe just a way of revenge, Chara corrupted the save file. Now, all the monsters that (Y/N) befriended are out to kill her. Can (Y/N) survive? Will she defeat Chara and find a way to get her friends back to normal? Or will she instead join Chara and erase everything? Find out in Into Hell. Once again I'm making the gender pronouns she because it makes it so much easier to write, which means quicker updates. I'm really sorry if your a male.

Gaster is the current royal scientist, set with a mission to break the barrier and free monster-kind from their underground prison. His loyalty and persistence to the task is clear, since he'll make whatever sacrifice necessary to complete it. However, even a perfectionist can be blind to some of their own flaws. Gaster has a habit of pushing things or himself too far. An accident occurs in the lab. Whilst trying to save him; one of his lab assistants, Y/N, gets injured. Burdening himself with even more pressure and guilt to fix it, Gaster thinks that doing all of her work for her will cover up the incident. Still, the sad reality is that the damage can't be undone. Well, Gaster ends up spending more and more time with her. As a result, both of them gain an entirely new perspective of the other, they aren't just another monster in a lab coat anymore. Hey! It's Oreo aka Writer~San! Undertale, it's characters, and it's fanart do not belong to me. However, the story does!!! I hope you enjoy it! (^w^)~
