"Dipper, Dipper!" Mable yells, shaking her brother awake.

"Huh? Mable? Whats wrong?" Dipper asks while yawning.

"There's a cat thing outside of our door! It's asking for a contract?" She practically yells.

"Huh?" The boy gets up out of his bed and picks up a big book with a big '3' on the front. He flips through the book while his sister joins him.

"What did it look like?" Dipper asks Mable.

"Ummm...Like a white cat creature..with really weird ears." Mable replies. As Dipper looks through the book he sighs.

"I don't think i'm going to be able to find it without knowing more about it." He says. "Is the creature still out there?"

"Yeah I think!" Mable says grinning. "Lets go find it!" They both get up and head towards the door of the shack. Mable jumps up and down, trying to look through the little peep hole in the door.

"Dip! Its still out there." She says. Dipper nods and slowly opens the door open. Then he quickly swings it open the rest of the way, creating a loud boom, hoping that it will scare the creature. When Dippers eyes clear he then sees a...a...white cat thingy.

"Huh? What are you?" He asks out loud.

"Hello. My name is Kyubey. Would you like to make a contract?" It asks.

"Huh? A contract?" Dipper asks.

"Yes! A contract! You can become a magical girl if you would like, only for the low price of making a contract with me!" Kyubey says, without moving its mouth.

"A magical...girl?!" Dipper asks. "I am not a girl!"

Kyubey tilts his head to one side. "Oh. My mistake. Well then how about you? Would you like to make a contract and help save the universe?"

Mable looks at the creature and gasps. "HUH? Me? Save the universe?" Dipper on the other hand haw now looking down at the ground, muttering something about looking like a girl.

"Yes! All you have to do is make a contract with me! First you will have to tell me what you wish for, and I will grant it! You will then become a magical girl!" Kyubey replies.

"Any wish! Oh wow! Well, then I wish for-" Mable started. She was cut off by a loud explosion. Dust flew into the air and a larg blast of wind caused Mable and Dipper to fall down.

"Mable!" Dipper called out. "Are you okay?"

"Dip! I'm fine!" Mable says, running towards her brother. "But where did Kyubey go?" She asks once the dust cleared. There was a large pile of fur where Kyubey had once stood. Was it...dead?

"Oh i'm sorry about that it seems someone is trying to stop me from making a contract." A voice said from behind the twins.

"AH! What just happened?" Mable said jumping back. "I thought you had died."

Suddenly a girl with blonde hair jumped down in front of them and Kyubey. She glared at the creature.

"What do you think your doing? Moving into another universe? Where not going to let you ruin this universe also! Leave now!" The mystery girl yelled.

"You won't let me you say? Why is that? I'm just helping this universe you know. But I guess i'll leave for now." Kyubey responded without showing any emotion. The creature jumped on top of the shack and vanished. The blonde girl turned around to the two kids.

"If you ever see that creature again, never make a contract with it please. You will regret it forever. It will come back to bite your back later in your life." She says seriously. "I hope you take this seriously."

Mable's eyes widened. "Why? Are you a magical girl? Why can't I become one?" She asks. Mable thought that this girl looked reaaallly cool! She was super pretty and she was saving the universe? Mable wanted to do that to!

The girl softly smiled. "Yes, I am. But I deeply regret making this decision. You see, Kyubey tricks girls and then steals their souls."

"Wait what? Iv never heard of anything like that, nor read anything like that in the book!" Dipper cried out.

"That makes since. You see, we come from a different universe. The things we kill have come into this universe. They are called 'witches'." She says. "Me and some fellow magical girls have come into your universe to try to eliminate the witches before they take over everything." The girl says.

"Hey Mami! Where did you go?" A voice calls in the distance.

"It seems i'll have to go. Stay safe." The girl says, smiling.

"Wait! I wan't to know more about this 'magical girl' stuff!" Mable calls out. The girl had already left before Mable had time to chase after her. "Weird...I wonder what that was all about." She says.

Dipper nods. "Yeah...I had never heard about anything like that." Dipper was very confused. These so called 'Magical Girls' had come from a different universe? They had their souls stolen? They battle witches? It was all very interesting, and there was nothing like this in the book! He could make a huge discovery!

"Mable. We are going to find out more about them." Dipper stated and Mable cheered and twirled in circles while holding Waddles.

AN: Yeah I really don't know. But this is happening! I had this idea when I was half awake (When I have all my good ideas). So hopefully this will end up being good. Thanks for reading!
