I am (Y/N). I'm 15 years old. I'm a big fan of Undertale. And with some of my friends, we have a power that every fan of Undertale would kill to have. We can travel through the Multiverse. Thanks to @UndertaleFan69 for posting this comment where everything started.

This is from the readers point of view. You don't know where you came from. You don't know where you've been. You don't even recognise yourself. You're lying in the street whilst it's pouring it down. Your hurt and alone. Your clothes are in even worse condition than you are. You feel that your going to die there. Until a short, joking skeleton named Sans, Invites you to come and live with him, and his brothers.

The barrier was lifted, the monsters were free but not accepted; hell broke loose, the wars were resumed. The monsters had no choice but to retaliate to the human's advances. Resources were scarce, the earth seemed unhabitable and the only way to survive was through violence. You lost all hope when you were forced to comply to such vile doings; being left alone by your family loosing them to a friendly fire during an escape. You were all alone; until he came along. ☆Violence, Cursing, Sexual Themes☆ ☆Gender-Neutral Reader☆ ☆Slowburn☆

[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)

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.
