A crazy world (multi-fandom x reader)

Chapter 1: Welcome to Gravity Falls

[Third person P.O.V]

Ahhhhhhh finally, summer vacation! The Birds are singing and the flowers were blooming, on days like this, kids like you...

Are stuck on a smelly old bus. Why you must ask? Because your parents are to busy to hang out with you so you're going to a place no one even knows about, but your parents know about it and sent you there. out of all places. For the whole summer vacation. They had friends there from high school that they just got in touch with. They apparently have a niece and a nephew that are a little younger then you (You're around 14-15).

It was nice because you were the only one on the bus. The bus stopped and opened the doors waiting for you to get off. You rolled your F/C suitcase off the bus and onto the dusty path. You looked up and saw a... tourist trap. oh boy. The letters on the roof said 'Mystery hack' but the 's' must have fallen off. You snicker at it.

Then you saw a boy wearing an orange shirt, blue vest, a hat with a pine tree on it, and shorts. Then there was a girl that looked just like him but with braces, a red sweater with a shooting star on it. The boy had a book in his hand that looked...Very interesting.

The, guessing, twins saw me and walked over too where you were standing. "HI IM MABEL, WHAT'S YOUR NAME," Mabel asked kind of loud while shaking you by the shoulders. The boy was trying to pry Mabel off of her new found friend. He eventually got the brown haired girl of off you. "Heh, don't mind my sister. I'm Dipper Pines" Dipper help out his hand. Y/N shook it with a smile. "I'm Y/N L/N. Nice to meet you" You said. Mabel gasps "Are you the one staying with us?!" She basically yelled. "Yes, I am," You said [as you posed awesomely] to them both. They both seemed happy about it. 'This summer isn't going to be so bad after all' You thought to yourself

After talking a little while outside, they showed you to their room. 'guess I'm sleeping on the floor' you thought. "Sorry for making you sleep on the floor," Dipper said. "Oh, it's fine." You said with a grumble. Dipper and Mabel laughed.

You, Dipper, and Mabel were sitting in the living room watching TV and passing around a bowl of corn chips. Dipper and Mabel were sitting on the chair and you were on the floor in front of them. All of the sudden a floating triangle just came in the room like nothing weird about that. You jumped and the chips went on the floor. The twins just looked at you like nothing was happening. "Y/N, what's wrong?" Dipper asked. "Y-you guys don't see that!" You pointed to were the 'thing' was. They just looked at you like you were crazy! Then everything went black and white. There was a demonic laugh from the 'thing'. "BILL" Mabel yelled. 'WHAT? IT HAS A NAME' you thought. "Of course I have a name Y/N L/N. I'm Bill, Bill Cipher" Bill announced. "H-how did you know my name?!" You asked. "I know everything that this universe holds little diamond," Bill said.

Bill looked down at the spilled bowl of chips and kind of looked, frightened. "W-well gotta go shooting star, pine tree, little diamond. Remember, reality is an illusion, the universe is a hologram, buy gold BYYYEEEE" then he disappeared.

'This is going to be interesting' you thought grimly.
