One of them. Dipper gleeful x reader

Thats so cool!

   You were always not quite right in the head. You had always loved beating people and had almost murdered your sister. Your parents thought it would be best to ship you to gravity falls so you couldn't hurt anyone else at your house.

   You were walking down the street when you saw 3 girls. The one who looked like the leader had a black leotard, turquoise jacket, turquoise headband, brown hair , and black heels.
   The one who looked like she was the fighter of the group was heavy set, had on a purple shirt, blue jeans, and had short brown hair. While the other girl had on a green blouse, glasses, black leggings, and black short hair.
   Suddenly a boy came up to them and gave something to the leader. It said I love you in it.
   The girl who was heavy set attacked the boy and nocked him unconscious.
   "Woah!" You said as you walked up to the girls.
   "What should we beat you too?" The leader said.
   "No." You say admiring the leader and the fighters bloody fists, "just that was so cool! I love beating random people!"
   "Then you should be my friend!" Said the leader of the group.
   "Really?"
   "Yea. My name is Mabel gleeful. This is candy." She said pointing to the short one with glasses, " and this is Grenda!" She says pointing to the heavy set one.
   "I'm y/n l/n. I think we could be good friends."
   "So are you gonna show us your house or is show you our houses first?" Mabel asks.
   "Oh I don't have a house my mom shipped me off here alone with no money cause I tried to kill my sister." You say twirling your hair.
   "Oh we are DEFINITELY going to be best friends! By the way you can stay with me and my brother in our mansion." She says putting her arm around you , "Come on I'll show you the place. Btw Grenda Candy, your houses await you."
   Once you get to Mabel's mansion she shows you a room full of turquoise things suck as a bed, a dresser, a desk, a nightstand with a lamp, ext.
   "This is your room. Let's get you introduced to my brother." She says excitedly.
   You walk to a living room the size of your whole house back at home and see a boy who looks like Mabel sitting on the couch.
   "Brother dear! This is y/n she is gonna be my new friend she is staying here."
   "Have you given here the test yet?"
   "No brother dear I was waiting for you!" She says pulling you and the boy to the kitchen.
   She grabs a dagger and hands it to you then her and her brother grab one for themselves.
   "By the way did I mention my name is Dipper." The boy dipper says.
   "Come with me. Time to put your brain to the test!" She says pulling you to the courtyard.
   There is a girl with a sweater that reads Pacifica, blonde hair, purple skirt, chip earrings, and black flats chained up to the wall.
   "So this is our enemy Pacifica pines! Come and have some fun with her." Mabel says twirling the dagger.
   Mabel walked up and put the dagger to Pacifica's arm.
   "Don't be shy like this!" Mabel says as she cuts deep into Pacifica's arm.
   "Don't mind if I do!" You say cutting into her other arm.
   You stab her hard in the stomach and evil laugh.
   In return Mabel pats your back and so does Dipper.
   "Your a gleeful now!" She says while dipper nods.
   Dipper finished Pacifica off and throws her into a hole.
   Mabel pulls out a necklace that has the same blue charm as dippers bow tie and Mabel's head band. She hands it to you.
   "With this you can use telekinesis!" She says as you gladly put on the necklace.
   "Thanks sister dear! Feels good to finally be with people of my style!" You say putting your arms around the two twins. The twins smile and walk inside whit you.
